Exploring the Relationships Between Bacterial Community, Taste-Enhancing Peptides and Aroma in Thai Fermented Fish (Pla-ra).

As a traditional Thai condiment, Pla-ra is used to add flavor and richness to dishes. Nine treatment combinations of Pla-ra formulations created from 3 types of fish (Mor fish, Kradee fish, and Mor + Kradee fish) and 4 different carbohydrate sources (none, rice bran, roasted rice, and rice bran─roasted rice mixture) were studied through a 12 month fermentation period (1, 3, 5, 7, 8, 9, 10, 11, and 12 months). 16S rRNA Next Generation Sequencing (NGS) and LC-MS/MS techniques were used to analyze the microbial diversity and identify taste-enhancing peptides. Descriptive sensory analysis was performed on the extracts of the 108 Pla-ra samples mixed in a model broth. Koku perception and saltiness-enhancing attributes were clearly perceived and dominant in all samples, even though glutamyl peptides, including γ-Glu-Val-Gly, were found at subthreshold levels. The samples from mixed fish and Mor fish fermented with roasted ground rice and rice bran for 12 months had the most typical Pla-ra odors and tastes and had high taste-enhancing activities. NGS analysis revealed the presence of bacteria containing a large number of protease and aminopeptidase genes in the samples. Bacillus spp., Gallicola spp., and Proteiniclasticum spp. correlated well with the generation of glutamyl and arginyl peptides and typical odors in the samples. These results confirmed the typical sensory quality of Pla-ra depended on protein sources, carbohydrate sources, and bacteria communities. Further optimization of the microbial composition found could lead to the development of starter cultures to control and promote flavor development in fermented fish products.

Fortification of condiments and seasonings with iron for preventing anaemia and improving health.

BACKGROUND: Anaemia affects approximately 1.8 billion people worldwide; over 60% of anaemia cases globally are due to iron deficiency (ID). Iron deficiency and anaemia contribute to the global burden of disease and affect physical and cognitive development in children, and work productivity and economic well-being in adults. Fortification of food with iron, alone or in combination with other nutrients, is an effective intervention to control ID. Condiments and seasonings are ideal food vehicles for iron fortification in countries where they are commonly used. OBJECTIVES: To determine the effects and safety of condiment and seasoning fortification with iron alone or iron plus other micronutrients on iron deficiency, anaemia, and health-related outcomes in the general population. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, and other databases up to 24 January 2023. We also searched the International clinical trials registry platform (ICTRP) for any ongoing trials. SELECTION CRITERIA: We included randomised controlled trials (RCTs) (randomisation at individual or cluster level), non-randomised controlled trials, interrupted time series with at least three measure points both before and after intervention, and controlled before-after studies. Participants were populations of any age (including pregnant women), from any country, excluding those with critical illness or severe co-morbidities. We included interventions in which condiments or seasonings have been fortified with any combination of iron and other vitamins and minerals, irrespective of the fortification technology used. DATA COLLECTION AND ANALYSIS: Two review authors independently screened and assessed the eligibility of studies. Disagreements were resolved through discussion or input from a third review author. Two review authors extracted the data and assessed the risk of bias in all the included studies. We followed the methods laid out by Cochrane and used GRADE criteria for assessing certainty of the evidence. MAIN RESULTS: Our search identified 15,902 records after removal of duplicates. We included 16 studies with 20,512 participants (18,410 participants after adjusting for clustering effects). They were all carried out in upper-middle- and lower-middle-income countries. Three studies were controlled before-after studies, one was non-randomised trial, and 12 were RCTs (including three cluster RCTs). Six studies took place in schools; seven in communities; and one each in a nursery/kindergarten, tea estate, and factory. Three studies involved only women, one study involved both women and their children, and all other studies focused on children and/or adolescents. Nine studies used salt as a vehicle for iron fortification, three used fish sauce, two used soy sauce, one used curry powder, and one a "seasoning powder". The dose of iron received by participants ranged from 4.4 mg to 55 mg/day. The sample sizes in the trials ranged from 123 to 14,398, and study durations ranged from three months to two years. Twelve RCTs contributed data for meta-analysis. Six trials compared iron-fortified condiments versus the unfortified condiment, and six trials provided data comparing iron fortification in combination with other micronutrients versus the same condiment with other micronutrients, but no added iron. In one trial, the fortificant contained micronutrients that may have affected the absorption of iron. Overall no studies were assessed as having a low risk of bias. All included studies were assessed to have a high overall risk of bias, with the most concerns being around allocation concealment, blinding, and random sequence generation. There was very high heterogeneity amongst studies in almost all examined outcomes. Condiments/seasonings fortified with iron versus unfortified condiments/seasonings We are uncertain about whether consuming condiments/seasonings fortified with iron in comparison to the same unfortified condiment reduces anaemia at the end of intervention (risk ratio (RR) 0.34, 95% confidence interval (CI) 0.18 to 0.65; 2328 participants; 4 studies; very low-certainty of evidence). We are uncertain about whether consuming iron-fortified condiments increases haemoglobin concentrations (mean difference (MD) 6.40 (g/L), 95% CI -0.62 to 13.41; 2808 participants; 5 studies; very low-certainty evidence). Fortification of condiments/seasonings with iron probably slightly reduces ID (RR 0.33, 95% CI 0.11 to 1.01; 391 participants; 2 studies; moderate-certainty evidence). We are uncertain about whether fortification with iron increases ferritin concentration (MD 14.81 (µg/L), 95% CI 5.14 to 24.48; 4459 participants; 6 studies; very low-certainty evidence). Condiments/seasonings fortified with iron plus other micronutrients versus condiments/seasonings fortified with other micronutrients except iron Consuming condiments/seasonings fortified with iron plus other micronutrients may reduce anaemia (RR 0.59, 95% CI 0.40 to 0.89; 1007 participants; 4 studies; low-certainty evidence). We are uncertain about whether fortification of condiments/seasonings with iron plus other micronutrients will improve haemoglobin concentration (MD 6.22 g/dL, 95% CI 1.60 to 10.83; 1270 participants; 5 studies; very low-certainty evidence). It may reduce ID (RR 0.36, 95% CI 0.19 to 0.69; 1154 participants; 4 studies; low-certainty evidence). We are uncertain about whether fortification with iron plus other micronutrients improves ferritin concentration (MD 10.63 µg/L, 95% CI 2.40 to 18.85; 1251 participants; 5 studies; very low -certainty evidence). Condiments/seasonings fortified with iron versus no intervention No trial reported data on this comparison. No studies reported adverse effects. Funding sources do not appear to have distorted the results in any of the assessed trials. AUTHORS' CONCLUSIONS: We are uncertain whether consuming iron-fortified condiments/seasonings reduces anaemia, improves haemoglobin concentration, or improves ferritin concentration. It may reduce ID. Findings about ferritin should be interpreted with caution since its concentrations increase during inflammation. Consuming condiments/seasonings fortified with iron plus other micronutrients may reduce anaemia, and we are uncertain whether this will improve haemoglobin concentration or ferritin concentration. More studies are needed to determine the true effect of iron-fortified condiments/seasonings on preventing anaemia and improving health. The effects of this intervention on other health outcomes like malaria incidence, growth and development are unclear.

ANTECEDENTES: La anemia afecta aproximadamente a 1800 millones de personas en todo el mundo; más del 60% de los casos de anemia en el mundo se deben a la deficiencia de hierro (DH). La deficiencia de hierro y la anemia contribuyen a la carga mundial de morbilidad y afectan al desarrollo físico y cognitivo de los niños, así como a la productividad laboral y el bienestar económico de los adultos. El enriquecimiento de los alimentos con hierro, solo o en combinación con otros nutrientes, es una intervención eficaz para controlar la DH. Los condimentos y sazonadores son vehículos alimentarios ideales para el enriquecimiento con hierro en los países donde se utilizan habitualmente. OBJETIVOS: Determinar los efectos y la seguridad del enriquecimiento de condimentos y aderezos con hierro solo o hierro más otros micronutrientes sobre la deficiencia de hierro, la anemia y los desenlaces relacionados con la salud en la población general. MÉTODOS DE BÚSQUEDA: Se realizaron búsquedas en CENTRAL, MEDLINE, Embase, CINAHL y otras bases de datos hasta el 24 de enero de 2023. También se realizaron búsquedas de ensayos en curso en la Plataforma de registros internacionales de ensayos clínicos (ICTRP). CRITERIOS DE SELECCIÓN: Se incluyeron ensayos controlados aleatorizados (ECA) (asignación aleatoria a nivel individual o grupal), ensayos controlados no aleatorizados, series temporales interrumpidas con al menos tres puntos de medición tanto antes como después de la intervención, y estudios controlados del tipo antes­después. Los participantes fueron poblaciones de cualquier edad (incluidas mujeres embarazadas), de cualquier país, excluidos aquellos con enfermedades críticas o comorbilidades graves. Se incluyeron las intervenciones en las que los condimentos o sazonadores se han enriquecido con cualquier combinación de hierro y otras vitaminas y minerales, independientemente de la tecnología de enriquecimiento utilizada. OBTENCIÓN Y ANÁLISIS DE LOS DATOS: Dos autores de la revisión seleccionaron y evaluaron de forma independiente la elegibilidad de los estudios. Los desacuerdos se resolvieron mediante debate o aporte de material de un tercer autor de la revisión. Dos autores de la revisión extrajeron los datos y evaluaron el riesgo de sesgo en todos los estudios incluidos. Se siguieron los métodos establecidos por Cochrane y se utilizó el método GRADE para evaluar la certeza de la evidencia. RESULTADOS PRINCIPALES: La búsqueda identificó 15 902 registros tras eliminar los duplicados. Se incluyeron 16 estudios con 20 512 participantes (18 410 participantes después de ajustar los efectos del conglomerado). Todos ellos se llevaron a cabo en países de ingresos medios­bajos y medios­altos. Tres estudios fueron controlados del tipo antes­después, uno fue un ensayo no aleatorio y 12 fueron ECA (incluidos tres ECA grupales). Seis estudios tuvieron lugar en escuelas, siete en comunidades y uno en una guardería, uno en una plantación de té y uno en una fábrica. En tres estudios participaron solo mujeres, en un estudio participaron tanto mujeres como sus hijos, y todos los demás estudios se centraron en niños y/o adolescentes. Nueve estudios utilizaron la sal como vehículo para el enriquecimiento con hierro, tres la salsa de pescado, dos la salsa de soja, uno el curry en polvo y otro un "sazonador en polvo". La dosis de hierro recibida por los participantes osciló entre 4,4 mg y 55 mg/día. El tamaño muestral de los ensayos osciló entre 123 y 14 398, y la duración de los estudios, entre tres meses y dos años. Doce ECA aportaron datos para el metanálisis. Seis ensayos compararon condimentos enriquecidos con hierro versus el condimento no enriquecido, y seis ensayos proporcionaron datos que comparaban el enriquecimiento con hierro en combinación con otros micronutrientes versus el mismo condimento con otros micronutrientes, pero sin hierro agregado. En un ensayo, el fortificante contenía micronutrientes que podrían haber afectado la absorción del hierro. En general, no se evaluó ningún estudio como de riesgo de sesgo bajo. Se evaluó que todos los estudios incluidos tenían un riesgo de sesgo general alto, y las mayores preocupaciones se centraron en la ocultación de la asignación, el cegamiento y la generación de secuencias al azar. Hubo una heterogeneidad muy alta entre los estudios en casi todos los desenlaces examinados. Condimentos/sazonadores enriquecidos con hierro versus condimentos/sazonadores no enriquecidos Es incierto si el consumo de condimentos/sazonadores enriquecidos con hierro en comparación con el mismo condimento no enriquecido reduce la anemia al finalizar la intervención (razón de riesgos [RR] 0,34; intervalo de confianza [IC] del 95%: 0,18 a 0,65; 2328 participantes; cuatro estudios; evidencia de certeza muy baja). Es incierto si el consumo de condimentos enriquecidos con hierro aumenta las concentraciones de hemoglobina (diferencia de medias [DM] 6,40 g/l; IC del 95%: ­0,62 a 13,41; 2808 participantes; cinco estudios; evidencia de certeza muy baja). El enriquecimiento de condimentos/sazonadores con hierro probablemente reduce ligeramente la DH (RR 0,33; IC del 95%: 0,11 a 1,01; 391 participantes; dos estudios; evidencia de certeza moderada). Es incierto si el enriquecimiento con hierro aumenta la concentración de ferritina (DM 14,81 µg/L; IC del 95%: 5,14 a 24,48; 4459 participantes; seis estudios; evidencia de certeza muy baja). Condimentos/sazonadores enriquecidos con hierro y otros micronutrientes versus condimentos/sazonadores enriquecidos con otros micronutrientes excepto hierro El consumo de condimentos/sazonadores enriquecidos con hierro más otros micronutrientes podría reducir la anemia (RR 0,59; IC del 95%: 0,40 a 0,89; 1007 participantes; cuatro estudios; evidencia de certeza baja). Es incierto si el enriquecimiento de condimentos/sazonadores con hierro más otros micronutrientes mejorará la concentración de hemoglobina (DM 6,22 g/dL; IC del 95%: 1,60 a 10,83; 1270 participantes; cinco estudios; evidencia de certeza muy baja). Podría reducir la DH (RR 0,36; IC del 95%: 0,19 a 0,69; 1154 participantes; cuatro estudios; evidencia de certeza baja). Es incierto si el enriquecimiento con hierro más otros micronutrientes mejora la concentración de ferritina (DM 10,63 µg/L; IC del 95%: 2,40 a 18,85; 1251 participantes; cinco estudios; evidencia de certeza muy baja). Condimentos/sazonadores enriquecidos con hierro versus ninguna intervención Ningún ensayo informó datos sobre esta comparación. Ningún estudio informó efectos adversos. Las fuentes de financiación no parecen haber distorsionado los resultados en ninguno de los ensayos evaluados. CONCLUSIONES DE LOS AUTORES: Es incierto si el consumo de condimentos/sazonadores enriquecidos con hierro reduce la anemia, mejora la concentración de hemoglobina o mejora la concentración de ferritina. Podría reducir la DH. Los resultados sobre la ferritina deben interpretarse con cautela, ya que sus concentraciones aumentan durante la inflamación. El consumo de condimentos/sazonadores enriquecidos con hierro más otros micronutrientes podría reducir la anemia, y no se sabe con certeza si mejorará la concentración de hemoglobina o de ferritina. Se necesitan más estudios para determinar el verdadero efecto de los condimentos/sazonadores enriquecidos con hierro en la prevención de la anemia y la mejora de la salud. Los efectos de esta intervención en otros desenlaces sanitarios como la incidencia del paludismo, el crecimiento y el desarrollo son inciertos.

The Potential of Condiments, Seasonings, and Bouillon Cubes to Deliver Essential Micronutrients in Asia: Scenario Analyses of Iodine and Iron Fortification.

Micronutrient deficiencies are still highly prevalent in Asia. Fortification of cooking aids, such as condiments (fish and soy sauces), seasonings, and bouillon cubes, may be an additional strategy to improve micronutrient intake. The current study evaluated the potential impact of iodine and iron fortification of cooking aids on micronutrient intake in Asian countries. A systematic literature search was performed to collect consumption data from different countries in Asia. Data from 18 studies in nine Asian countries were included. Scenario analyses were performed using different fortification levels based on regulations and literature. Mean intake of cooking aids ranged from 3.2-15.9 g/day for condiments and 0.4-11.7 g/day for seasonings and bouillon cubes. When replacing salt with iodized salt (30 µg of iodine/g of salt), iodine intake would increase by 13-119 µg/day for soy and fish sauces (9-80% of the Nutrient Reference Value (NRV)), and 5-83 µg/day for bouillon cubes and seasonings (4-56% of the NRV). Fortification with iron 0.5 mg/g food product for condiments or 1 mg/g food product for bouillon cubes and seasonings improved iron intake for soy and fish sauces by 1.6-8.0 mg/day (11-57% of the NRV), and for bouillon cubes and seasonings by 0.4-5.6 mg/day (3-40% of the NRV). These results indicate that, depending on the consumption pattern, fortification of cooking aids can be a suitable strategy to increase intake of micronutrients.

Formation, texture, and stability of yolk-free mayonnaise: Effect of soy peptide aggregates concentration.

A kind of yolk-free mayonnaise (YFM) with preferable quality was prepared by insoluble soy peptide aggregates (ISPA) in present work. The basic properties, rheology, texture, sensory quality, and stability for YFM with different concentration of ISPA were explored. As ISPA concentration increased from 1.50 wt% to 3.00 wt%, the droplet size of YFM decreased by 5.35 µm, while the storage and loss modulus increased 2.02 and 1.99 times, moreover, the thixotropic recovery percentage, hardness and gumminess of YFM increased to 95.84 %, 13.29 g and 10.05, respectively. Meanwhile, the ISPA concentration had positive effect on the oxidation stability and thermal stability for YFM. Noticeably, YFM with 2.75 wt% ISPA had good textural properties and sensory quality, which were close to those of commercial mayonnaise. In conclusion, YFM prepared by ISPA had low cholesterol level, which provided a new strategy for solving the health problems of traditional mayonnaise.

Influence of an Edible Oil-Medium-Chain Triglyceride Blend on the Physicochemical Properties of Low-Fat Mayonnaise.

Mayonnaise is a semisolid oil-in-water emulsion comprised of egg yolk, oil, and vinegar. One main problem with mayonnaise is its high fat content, so efforts have been made to develop low-fat sauces with similar characteristics to real mayonnaise. The purpose of this study was to evaluate the effect of medium-chain triglycerides (MCTs) blended with edible oil (soybean and olive oil) on the rheological, physicochemical, and sensory properties of low-fat mayonnaise. The results revealed that the shear viscosity decreased with the increase in medium-chain fatty acid (MCFA) contents and decreased with an increasing shear rate. Tan δ was <1, and a semisolid fluid with shear-thinning behavior was formed. The oscillation frequency test showed that the MCFA-containing mayonnaise was viscoelastic. The particle size and oil droplet analyses revealed that the emulsion droplet size and distribution were not significantly different in the MCT group compared to the control. The sensory evaluation demonstrated that the MCFA-containing mayonnaise was acceptable. This study illustrates that MCTs are a good substitute to produce the proper physicochemical properties of mayonnaise.

Fermented shellfish condiments: A comprehensive review.

Fermented shellfish condiments are globally consumed especially among Asian countries. Condiments, commonly used as flavor enhancers, have unique sensory characteristics and are associated with umami and meaty aroma. The main reactions that occur during fermentation of shellfish include proteolysis by endogenous enzymes and microbial activities to produce peptides and amino acids. The actions of proteolytic enzymes and microorganisms (predominantly bacteria) are found to be largely responsible for the formation of taste and aroma compounds. This review elaborates different aspects of shellfish fermentation including classification, process, substrates, microbiota, changes in both physicochemical and biochemical components, alterations in nutritional composition, flavor characteristics and sensory profiles, and biological activities and their undesirable impacts on health. The characteristics of traditional shellfish production such as long duration and high salt concentration not only limit nutritional value but also inhibit the formation of toxic biogenic amines. In addition, this review article also covers novel bioprocesses such as low salt fermentation and use of novel starter cultures and/or novel enzymes to accelerate fermentation and produce shellfish condiments that are of better quality and safer for consumption. Practical Application: The review paper summarized the comprehensive information on shellfish fermentation to provide alternative strategies to produce shellfish comdiments that are of better quality and safer for consumption.

Effect of humectants and Zygosaccharomyces bailii inoculation on the physical stability of oil-in-water emulsions modeling salad dressings.

BACKGROUND: Salad dressing formulations include a pH within 3.2-4.1, salt and other solutes to depress water activity. The interaction between hydrocolloids and other components such as humectants determines their physical and microbiological stability. To our knowledge, the effect of commonly used solutes on physical stability and rheological characteristics of oil-in-water emulsions stabilized by xanthan gum has not been reported, and neither has the effect of a spoilage yeast on physical stability been evaluated. RESULTS: The effect of different humectants (sodium chloride, glucose and xylitol) and Zygosaccharomyces bailii inoculation on the stability of oil-in-water emulsions containing different levels of xanthan gum to emulate different types of salad dressings was investigated by means of droplet size, zeta potential, rheological measurements and confocal laser scanning microscopy (CLSM). Generally, the addition of humectants strengthened the weak or strong emulsion structure, especially xylitol. Glucose or xylitol acted as stabilizers since they decreased Sauter and De Broucker diameter. On the contrary, NaCl destabilized the emulsions since it increased droplet size and exhibited the lowest absolute values of zeta potential. Inoculation with Z. bailii destabilized some emulsions since it increased Sauter and De Broucker diameter. Emulsion droplet size, polydispersity, and xanthan gum and yeast location were confirmed by CLSM imaging. CONCLUSION: This study highlights the key role of humectants and xanthan gum level on physical characteristics and stability of oil-in-water emulsions. Addition of xylitol leads to an enhancement in emulsion rheology and physical stability, suggesting that it is a potential low-calorie multifunctional additive for salad dressings. © 2022 Society of Chemical Industry.

Oil matrix modulates the bioaccessibility of polyphenols: a study of salad dressing formulation with industrial broccoli by-products and lemon juice.

BACKGROUND: The potential health-promoting effects of polyphenols depend considerably on their bioaccessibility, which is affected by the presence of other nutrients in the diet, including lipids. In this study, several salad dressing formulations were prepared using industrial broccoli by-product powder (BBP), lemon juice (LJ), and three different sources of oils (olive oil, hazelnut oil and sunflower oil) to both valorize polyphenol-rich industrial discards and also to investigate polyphenol bioaccessibility. The changes in the bioaccessibility of polyphenols from BBP and LJ were determined using the standardized in vitro digestion model. RESULTS: Four groups of polyphenols (hydroxycinnamic acids, flavonols, flavones, and flavonones) were detected in BBP and LJ. The bioaccessibility of hydroxycinnamic acids and flavonols from BBP increased significantly in the presence of LJ and oils (0.3- to 5.8-fold), whereas there was no significant difference between formulations containing different oil types. On the other hand, the bioaccessibility of phenolic acids from LJ did not change notably after co-ingestion with BBP and oils, whereas flavonoids, including vicenin-2 and hesperidin, were found to be significantly more bioaccessible when LJ was co-ingested with BBP and oils (0.8- to 1.4-fold) (P < 0.05). CONCLUSION: Overall, the current study highlighted that the bioaccessibility of polyphenols from BBP and LJ was modulated in the presence of an oil matrix. © 2022 Society of Chemical Industry.

Hypertension- and glycaemia-lowering effects of a grape-pomace-derived seasoning in high-cardiovascular risk and healthy subjects. Interplay with the gut microbiome.

Purpose: Grape pomace (GP) is a winery by-product rich in polyphenols and dietary fibre. Some recent results suggest that GP-derived extracts could be promising additives in food, specially recommended for low-salt diets. The hypothesis tested in this paper is that the regular consumption of GP-derived seasonings could help in the control of hypertension and glycaemia. Methods: A randomized intervention study (6 weeks) was performed in high-risk cardiovascular subjects (n = 17) and in healthy subjects (n = 12) that were randomly allocated into intervention (2 g day-1 of GP seasoning) or control (no seasoning consumed) groups. Blood samples, faeces, urine and blood pressure (BP) were taken at the baseline and at the end of the intervention. Faecal samples were analysed for microbiota composition (16S rRNA gene sequencing) and microbial-derived metabolites (short chain fatty acids and phenolic metabolites). Results: Among the clinical parameters studied, BP and fasting blood glucose significantly decreased (p < 0.05) after the seasoning intervention, but not for the control group. Notably, application of a novel approach based on ASV (Amplicon Sequence Variant) co-occurrence networks allowed us to identify some bacterial communities whose relative abundances were related with metadata. Conclusion: Our primary findings suggest that GP-seasoning may help in the modulation of cardiometabolic risk factors, mainly in the early stages. Furthermore, it evidences modulation of gut microbiota and functional bacterial communities by grape pomace, which might mediate the cardiometabolic effects of this by-product.

Exploring major variable factors influencing flavor and microbial characteristics of Pixian Doubanjiang.

Pixian Doubanjiang (PXDBJ) is a typical Asian condiment with a unique spicy flavor produced by traditional spontaneous solid-state fermentation. In this study, flavor and the microbial community characteristics of PXDBJ were investigated based on polyphasic detection approaches, and further revealed the potential regulations of the variable factors on its characteristics. Specifically, the chili varieties and the ripening periods affected the features of organic acids and amino acids, respectively. PLS-DA plot demonstrated that the volatiles contents varied by the intermediate product Banpei and the ripening periods although the predominant aroma compounds were roughly the same. Those results were verified by Spearman's arithmetic (P < 0.05), and established a chili variety-classification model based on OPLS-DA plot (Q2(cum) = 0.918, P < 0.05). In addition, the relative abundance of Saccharomycetales, Zygosaccharomyces, and Muribaculaceae varied with ripening periods, and further revealed the contributions of those variable factors to the flavor and correlated with the predominant microbes. This comprehensive study on the raw materials and spatiotemporal characteristics is valuable for exploring the fermentation mechanism and controlling the product quality.

The essential oil of the condiment species Clinopodium thymifolium (Scop.) Kuntze: new natural products and seasonal variation.

BACKGROUND: Clinopodium thymifolium is an aromatic plant species that is widespread in the Mediterranean region. It has been considered as a condiment and is used in cooking. As a promising spice plant, some efforts are being made to introduce this plant as a new crop species and it has been successfully cultivated in northern Italy. RESULTS: Essential oils isolated from the aerial parts of a flavoring species C. thymifolium were analyzed by gas chromatography and gas chromatography/mass spectrometry. The results of a detailed analysis of the chemical composition of the oils showed the domination of pulegone, piperitone, piperitenone and isomenthone, as well as a significant alteration of the pulegone/isomenthone ratio with the developmental stage of the plant. Additionally, a comprehensive chemical analysis of the oils in combination with detailed spectral analyses and chemical synthesis of selected compounds has led to the identification of two new natural products: isomenthyl formate and neomenthyl 2-methylbutanoate. CONCLUSION: The observed chemical variability at the intrapopulation level appeared to be a phenological variation. In an evolutionary sense, the alteration of the pulegone/isomenthone ratio suggests their possible role in the ecological adaptation of the species to pollinators. Significant quantitative changes in the chemical composition of the oil at different phenological stages may be relevant in the case of plant material intended for edible purposes. © 2021 Society of Chemical Industry.

Efeitos do sal de ervas sobre a pressão arterial e a excreção de sódio urinário de pessoas com hipertensão / Effects of herbal salt on blood pressure and urinary sodium excretion in people with hypertension

A presente pesquisa teve por objetivo analisar os efeitos da substituição do sal de cozinha por sal de ervas sobre os valores de pressão arterial e excreção de sódio urinário de pessoas com hipertensão arterial. Trata-se de um estudo de abordagem quantitativa e delineamento quasi-experimental, tipo "cross-over", com amostra de hipertensos cadastrados em três unidades públicas de saúde de um município do estado de Mato Grosso. A coleta de dados foi realizada no período de maio de 2020 a maio de 2022. Por meio de entrevista, foi aplicado o questionário para identificação das variáveis sociodemográficas e o "Questionário de Adesão a Medicamentos - Qualiaids" (QAM-Q). Posteriormente, foi realizada a avaliação antropométrica e a medida casual da pressão arterial. A pesquisa foi dividida em três etapas: Etapa 1 - os participantes permaneceram em uso habitual do sal de cozinha, durante sete dias; Etapa 2 - os participantes fizeram uso exclusivo de cinco gramas de sal por dia, durante 10 dias; Etapa 3 - os participantes usaram exclusivamente o sal de ervas para o preparo das refeições, durante 10 dias. Em todas as etapas, foi realizada a Monitorização Residencial da Pressão Arterial (MRPA) e a dosagem de sódio urinário. As análises descritivas foram realizadas por meio do pacote estatístico IBM Statistical Package for Social Science - SPSS®, versão 25.0. O teste ANOVA foi utilizado para comparações entre as médias pareadas. Os resultados foram expressos como valores médios, desvio padrão (dp), mínimo, máximo e mediana. Para diferença estatística foi considerado p<0,05. Participaram do estudo 24 indivíduos, com idade média de 63,2 ± 10 anos, a maioria mulheres (54,2%), que convivem com companheiro (70,8%), de cor da pele autodeclarada branca (54,2%), com média de 7,6 anos de estudo e aposentados (45,8%). Em relação às variáveis clínicas, houve predomínio de participantes com pressão arterial ótima (45,8%), na categoria sobrepeso (45,8%), com risco cardiovascular elevado segundo relação cintura-estatura (87,5%) e risco muito elevado de acordo com a medida da circunferência da cintura (54,1%); 62,5% se mostraram aderentes ao tratamento. Na comparação entre as três etapas, observou-se redução significante nos valores de Pressão Arterial Sistólica (p=0,003) e Pressão Arterial Diastólica (p=0,001), sem diferença nas variáveis consumo de sal (p=0,66) e excreção de sódio urinário (p=0,66). Ainda que o uso do sal de ervas seja uma estratégia não medicamentosa interessante e inovadora para o controle da pressão arterial, os participantes não aderiram de forma expressiva à intervenção proposta. De qualquer forma, salienta-se que a monitorização do consumo de sódio é primordial para a avaliação do uso do sal pela população, tendo em vista a implementação de medidas visando a redução da pressão arterial e a prevenção de eventos cardiovasculares

The present research aimed to analyze the effects of replacing table salt with herbal salt on blood pressure values and urinary sodium excretion in people with hypertension. This study has a quantitative approach and quasi-experimental design, "cross-over" type, with a sample of hypertensive patients registered in three public health units in a municipality in the state of Mato Grosso. Data collection was carried out from May 2020 to May 2022. Through an interview, the questionnaire to identify sociodemographic variables and the "Medication Adherence Questionnaire - Qualiaids" (QAM-Q) were applied. Subsequently, anthropometric assessment and casual blood pressure measurements were performed. The research was divided into three stages: Stage 1 - the participants kept the usual use of table salt for seven days; Stage 2 - participants made exclusive use of five grams of salt per day for ten days; Stage 3 - participants used only herbal salt to prepare meals for 10 days. Residential blood pressure monitoring and urinary sodium measurement were performed at all stages. Descriptive analyzes were performed using the IBM Statistical Package for Social Science - SPSS® program, version 25.0. The One Way test was used for comparisons between the paired mean values. Results were expressed as mean values, standard deviation (sd), minimum, maximum, and median. For statistical difference, p<0.05 was considered. Participated in the research 24 individuals, with a mean age of 63.2 ± 10 years, most of them was women (54.2%), who live with a partner (70.8%), self-declared white skin color (54.2%), with an average of 7.6 years of formal education and retired (45.8%). Regarding clinical variables, it was observed a predominance of participants with optimal blood pressure (45.8%), in the overweight category (45.8%), with high cardiovascular risk according to the waist-to-height ratio (87.5%), and very high risk according to waist circumference measurement (54.1%), 62.5% were adherent to the treatment. When comparing the three stages, there was a significant reduction in the values of systolic blood pressure (p=0.003) and diastolic blood pressure (p=0.001), with no difference in the variables salt consumption (p=0.66) and urinary sodium excretion (p=0.66). Although the use of herbal salt is an interesting and innovative non-drug strategy for blood pressure control, participants did not significantly adhere to the proposed intervention. Nevertheless, it should be noted that the monitoring of sodium consumption is essential for the evaluation of the use of salt by the population and to implement measures aimed at reducing blood pressure and preventing cardiovascular events

Ethyl carbamate (EC), a potential human dietary carcinogen, is found in fermented foods including the fermented soybean-based condiments, the major part of the Korean diet. Therefore, it is expected that their EC contents might pose health risks. Herein, we collected 111 condiments and estimated their EC contents via gas chromatography-mass spectrometry. Further, dietary intake of EC was evaluated, and the risk levels were assessed via the margin of exposure (MOE) approach and excess cancer risk assessment. EC contents of the condiments ranged from not detectable to 39.47 µg/kg, and the daily EC exposure ranged from 1.4 to 2.0 ng/kg BW per day, depending on gender and age groups in Korea. Of the condiments, soy sauce was the largest contributor to EC exposure. MOE and excess cancer risks for the average consumer were 166,300 and 9.0 × 10-8, respectively, and those for the consumers in the 95th percentiles (P95) were 53,504 and 2.8 × 10-7, respectively, indicating that the risk of exposure to EC is of lower concern in average consumers than heavy consumers. However, the EC exposure from condiments was higher than that in other Asian countries.Abbreviations: EC: ethyl carbamate; GC-MS: gas chromatography-mass spectrometry; MOE: margin of exposure; MRL: maximum residue level; IDL: instrumental detection level; IQL: instrumental quantification level; MDL: method detection level; MQL: method quantification level; EDI: estimated daily intakes; BMDL10: benchmark dose lower confidence limit.

Fabrication and characterization of basil essential oil microcapsule-enriched mayonnaise and its antimicrobial properties against Escherichia coli and Salmonella Typhimurium.

Nowadays, as consumers tend to avoid foods containing synthetic preservatives, technologically processed plant extracts can be a good alternative to these preservatives. In this study, previously obtained basil essential oil microcapsules (BEOM) were added to mayonnaise in order to produce a microbiologically safe product with improved physicochemical properties. Mayonnaises were prepared with 0%, 0.3%, 0.6%, and 0.9% BEOM replacement of the total oil content, called Mayo-Control, Mayo-0.3% BEOM, Mayo-0.6% BEOM, and Mayo-0.9% BEOM, respectively. Additionally, Mayo-SP containing ethylene diamine tetra-acetic acid and potassium sorbate was prepared. The enriched mayonnaises displayed better antimicrobial activity against Escherichia coli than Mayo-SP and Mayo-Control. Mayo-SP showed the best antimicrobial activity against Salmonella Typhimurium, followed by Mayo-0.9% BEOM. At the end of storage, Mayo-0.9% BEOM had the highest apparent viscosity, G', and G'' values due to its high content of gum molecules. Trans-2-heptanal, an oxidation product, was not identified in the enriched mayonnaises or Mayo-SP. Finally, BEOM were efficient in providing microbial safety of mayonnaise and also improved the product's oxidative stability, viscosity, and aroma.

Bioactive and Nutritional Potential of Medicinal and Aromatic Plant (MAP) Seasoning Mixtures.

Medicinal and aromatic plants (MAPs), worldwide appreciated and used as condiments, dyes, and preservatives, possess several biological properties that justify their continuous application in the food industry. In the present study, the nutritional and chemical profiles, as well as the bioactive properties of four combinations of condiments, sold for seasoning poultry, meat, fish, and salads, were evaluated. Twenty-five phenolic compounds (HPLC-DAD-ESI/MS) were identified, with apigenin-O-malonyl-pentoside-hexoside as the major compound detected in all extracts. Oxalic and citric acids were identified in all mixtures (UFLC-PDA), as well as all the four tocopherol isoforms (HPLC-fluorescence). Regarding bioactivities, the mixtures for meat and salads (TBARS) and meat and poultry (OxHLIA) stood out for their antioxidant potential, whereas for the anti-inflammatory and antitumor properties, the mixtures revealing the greatest results were those for poultry and salad, respectively. In terms of antimicrobial activity, all the mixtures revealed the capacity to inhibit the growth of some bacterial strains. In brief, condiment mixtures showed to be a good source of bioactive compounds, as they confer health benefits, validating the importance of their inclusion in the human diet as a good dietary practice.

Enrichment of mayonnaise with a high fat fish oil-in-water emulsion stabilized with modified DATEM C14 enhances oxidative stability.

Enrichment of mayonnaise using delivery emulsions (DEs) containing 70% fish oil versus neat fish oil was investigated. DEs were produced with combined use of sodium caseinate, diacetyl tartaric acid esters of mono- and diglycerides (DATEM), and/or modified DATEMs with different length (C12 or C14) and covalently attached caffeic acid. Physical and oxidative stability of the mayonnaises were analyzed based on parameters including droplet size, viscosity, peroxide value, volatile compounds, and sensory properties. DEs addition to mayonnaise resulted in larger droplets and lower viscosity compared to neat fish oil. However, zeta potential was higher in mayonnaises with DEs containing DATEMs. Mayonnaise containing DATEM C14 had higher protein surface load leading to a thicker interfacial layer, lower formation of hexanal, (E)-2-hexenal, and (E)-2-heptenal as well as lower rancid odour intensity compared to mayonnaise containing DATEM and free caffeic acid, and thus benefitted from the location of the antioxidant at the interface.

Reducing the burden of iron deficiency anemia in Cote D'Ivoire through fortification.

BACKGROUND: Iron deficiency anemia (IDA) is highly prevalent in the Cote d'Ivoire and has severe health and economic consequences. In this paper, we apply a health economic model to quantify the burden of IDA, and the contribution of nationwide mandatory iron fortification of wheat flour and voluntary iron fortification of condiments to the reduction of this burden. METHODS: The analysis for the population from 6 months to 64 years builds on published reviews and publicly available datasets and is stratified by age-groups and socioeconomic strata using comparative risk assessment model. RESULTS: Without the impact of these fortification strategies, the annual burden of IDA is estimated at 242,100 disability adjusted life years (DALYs) and 978.1 million USD. Wheat flour and condiment fortification contributed to a reduction of the IDA burden by approximately 5% each. CONCLUSION: In places with high prevalence of malaria and other infectious diseases, such as the Côte D'Ivoire, food fortification as a nutritional intervention should be accompanied with infectious disease prevention and control. The findings of this study provide additional input for policy makers about the magnitude of the impact and can support the conception of future fortification strategies.

Performance Factors Influencing Efficacy and Effectiveness of Iron Fortification Programs of Condiments for Improving Anemia Prevalence and Iron Status in Populations: A Systematic Review.

Iron fortification of staple foods is a common practice around the world to reduce the prevalence of iron-deficiency anemia. More recently, fortified condiments, including salts, sauces, and powders, have been tested in various efficacy trials. However, there is limited information on how nutritional, environmental, and experimental factors affect their efficacy and effectiveness. The purpose of the present work was to systematically review performance factors affecting the efficacy of condiment fortification trials. Three databases were searched using a standardized keyword search and included based on four-point inclusion criteria. Studies were evaluated against a quality assessment tool and effect sizes were calculated. Studies were ranked as low or high performing, based on whether or not they significantly improved iron-deficiency outcomes (hemoglobin, anemia prevalence, and ferritin levels). Of the 955 retrieved studies, 23 were included-of which, nine performed poorly, eight performed highly, and six were classified as neither because they did not meet the criteria of assessing the three iron outcomes. Results showed that unsuccessful trials did not consider environmental factors such as parasitic infections, nutritional factors such as micronutrient deficiencies other than iron, consumer acceptability of the product or experimental factors such as monitoring and adherence to the trials. Two common performing factors identified among those studies performing highly vs. those that did not were the control of sensory changes and monitoring of consumption compliance (i.e., dose delivery). The present work can be used as decision-making support for nutrition policy makers when determining the appropriate implementation of condiment fortification programs.

Antioxidant and antimicrobial evaluation of rice bran (Oryza sativa L.) extracts in a mayonnaise-type emulsion.

The objective of this study was to evaluate the in vitro antimicrobial and antioxidant activities of different bran extracts and concentrations, and their influence on the parameters of a mayonnaise-type emulsion. To that end, first ethanol and then water were used to extract two rice bran extracts (RBE) from rice bran. Both these extracts were then added at two different concentrations (0.5 and 2%) to the emulsions that were subsequently analysed after seven days under two different storage temperatures, 4 °C and 20 °C. The antioxidant and antimicrobial ability of the extracts were evaluated, along with a control and a synthetic antioxidant. Results indicate the positive effect of rice bran extracts as additives in the food matrix. Ethanolic rice bran extract (EE) at 2% decreased the oxidation as well as mould and yeast proliferation and preserved the emulsion structure, while the other treatments acted in a similar way although their effect was less pronounced.

Formulação de sal de ervas como promotor da redução de sódio em hambúrguer: avaliação sensorial e efeitos na formação de óxidos de colesterol / Formulation of herbal salt as a promoter of sodium reduction in beef burger: sensory evaluation and effects on the formation of cholesterol oxides

Introdução - A carne é um elemento central na alimentação, entretanto, diferentes condições podem levar a formação de produtos da oxidação do colesterol (POCs). Também os efeitos do excesso de sódio na pressão arterial estão bem documentados. Assim, o uso de sal de ervas poderia reduzir o teor de sódio e a formação de POCs. Objetivo - Avaliar os efeitos de diferentes concentrações de sal de ervas na aceitação da redução de sódio e na proteção contra a oxidação lipídica em hambúrguer. Material e Métodos - Os hambúrgueres foram adicionados de dois níveis de sal (0,60% e 1,90%) e dois níveis de orégano, alecrim e manjericão (0,36% e 0,72%). Aos controles FC1 (0,60% de sal) e FC2 (1,90% de sal), foram adicionadas duas concentrações de ervas, compondo as formulações F3 (0,60% de sal e 0,36% de ervas), F4 (1,90% de sal e 0,36% de ervas), F5 (0,60% de sal e 0,72% de ervas) e F6 (1,90% de sal e 0,72% de ervas). A aceitação sensorial foi realizada por escala hedônica e de intensidade do sabor. A cor e textura foram avaliadas por análises instrumentais. Foi realizada a caracterização físico-química das amostras cruas e grelhadas. A avaliação da oxidação lipídica foi realizada logo após o preparo e após 30, 60 e 90 dias de congelamento. Foram determinados os compostos fenólicos totais e a capacidade antioxidante das ervas. Resultados - Todas as formulações foram aceitas, sendo FC2, F3 e F4 as mais aceitas. No atributo sabor, F3 obteve média maior que FC2, indicando maior aceitação do sabor após adição de sal de ervas, em comparação a adição isolada de sal no teor regularmente consumido. A cor obteve médias de aceitação maiores para os controles. A análise instrumental da dureza não apresentou variações, porém pela avaliação sensorial as ervas auxiliaram na maciez. A maioria das formulações foram consideradas com salinidade e condimentação ideal. A retenção de umidade após a cocção foi maior com o uso de ervas. Os teores de fenólicos totais no orégano foi de 16,46 ± 0,25 mg EAG/g, no alecrim de 17,80 ± 0,18 mg EAG/g e no manjericão 3,24 ± 0,34 mg EAG/g. O uso de ervas não inibiu a oxidação lipídica durante a cocção e após, o armazenamento, a inibição ocorreu no teor reduzido de sal (F3 e F5 com 21% e 16%, respectivamente, em 30 dias e 54% e 59%, respectivamente, em 60 dias) e, em 90 dias, apenas F3 apresentou inibição de 22%. Os teores de colesterol variaram entre 35,25 ± 5,34 a 87,13 ± 8,05 mg/100g de amostra seca e a concentração de POCs totais foi de 68,19 ± 2,89 a 123,68 ± 4,51 µg/g de amostra seca. As formulações com ervas não apresentaram menores teores de POCs que os controles. Conclusão - Todas as formulações foram aceitas em todos os atributos, com maior aceitação a formulação adicionada de teor de sal reduzido e do menor teor de ervas, sendo também a formulação com menor oxidação e redução de sal de 40%. A adição de ervas não apresentou efeito sinérgico contra a formação de POCs.

Introduction - Meat is central element in the diet; however, different conditions can lead to the formation of cholesterol oxidation products (COPs). The effects of excess sodium on blood pressure are also well documented. Thus, the use of herbal salt could reduce the sodium content and the formation of POCs. Objective - To evaluate the effects of different concentrations of herbal salt on the acceptance of sodium reduction and protection against lipid oxidation in hamburgers. Material and Methods - The hamburgers were formulated with two levels of sodium chloride (0.60% and 1.90%) and two levels of herbal mixture (0.36% and 0.72%), composed of oregano, rosemary and basil. To the controls FC1 (0.60% of salt) and FC2 (1.90% of salt), different herbs proportions were added: F3 (0.60% of salt and 0.36% of the herbal mix), F4 (1.90% of the salt and 0.36% of the herbal mix), F5 (0.60% of the salt and 0.72% of the herbal mix) and F6 (1.90% of the salt and 0.72% herbal mix). Sensory acceptance was achieved by hedonic scale and flavor intensity. The color and texture were evaluated by instrumental analyzes. The physical and chemical characterization of raw and grilled samples was carried out. The evaluation of lipid oxidation was performed immediately after preparation and after 30, 60 and 90 days of freezing. The total phenolic compounds and the antioxidant capacity of the herbs were determined. Results - All formulations were accepted, with FC2, F3 and F4 being the most accepted. In the flavor attribute, F3 obtained an average greater than FC2, demonstrating greater acceptance of flavor after adding herbal salt, compared to salt in the content regularly consumed. The color obtains higher acceptance averages for the controls. An instrumental analysis of the hardness does not show variations, however, in the sensorial evaluation the herbs helped in the softness. Most formulations were evaluated with ideal salinity and seasoning. Moisture retention after cooking was greater with the use of herbs. The content of total phenolics in oregano was 16.46 ± 0.25 mg EAG / g, in rosemary 17.80 ± 0.18 mg EAG / g and in basil 3.24 ± 0.34 mg EAG / g. The use of herbs did not inhibit lipid oxidation during cooking and after storage the inhibition occurred reduced salt content (F3 and F5 with 21% and 16%, respectively, in 30 days and 54% and 59%, respectively, in 60 days) and in 60 days only F3 showed 22% inhibition. Cholesterol levels vary between 35.25 ± 5.34 to 87.13 ± 8.05 mg / 100g of dry sample and the concentration of total COPs was 68.19 ± 2.89 to 123.68 ± 4.51 µg / g of dry sample. The herbal formulations has no lower COPs content than controls. Conclusions - All formulations were accepted in all attributes, with preference for the formulation added with reduced salt content and the lowest herbal content, and also the formulation with less oxidation and 40% salt reduction. The addition of herbs has no synergistic effect against the formation of POCs.
