ABSTRACT

Introducción. La calidad de los carbohidratos consumidos juega un papel importante en la prevención de las enfermedades crónicas no transmisibles (ECNT). Objetivo. Analizar el índice de calidad de los carbohidratos (ICC) en la población urbana costarricense y su relación con las variables sociodemográficas, antropométricas y la calidad y la diversidad de la dieta. Materiales y métodos. Los datos provienen del Estudio Latinoamericano de Nutrición y Salud, en una muestra representativa de 798 personas entre 15 y 65 años que residen en zonas urbanas de Costa Rica (2014- 2015). En una visita domiciliaria se administró un cuestionario para recolectar los datos sociodemográficos y se pesó y midió a los participantes. El consumo dietético se obtuvo mediante dos recordatorios de 24 horas en días no consecutivos. El ICC se calculó mediante el consumo de fibra, el índice glicémico, la relación carbohidratos sólidos/líquidos y la relación granos enteros/granos totales. Se comparó el ICC según el sexo, el grupo de edad, el nivel socioeconómico, el estado nutricional, la circunferencia de cintura y la calidad y diversidad de la dieta de los participantes. Resultados. El ICC se asoció positivamente con un mayor consumo de energía, carbohidratos totales, proteínas, grasas, colesterol, frutas, vegetales y leguminosas (p<0,001). Un mayor ICC se asoció positivamente con un mayor porcentaje de adecuación de micronutrientes y mayor índice de diversidad y calidad de la dieta (p<0,001), así como con un menor índice de masa corporal y una menor circunferencia de cintura al ajustar por sexo y edad (p<0,005). Conclusiones. El presente estudio demostró que un mayor ICC se asocia significativamente con mejores indicadores dietéticos e índice de masa corporal, por lo que resulta fundamental establecer en Costa Rica pautas dietéticas que permitan aumentar la calidad de los carbohidratos de la dieta con el fin de contribuir en la prevención de las ECNT(AU)


Introduction. The carbohydrate quality index (CQI) plays an important role in the prevention of chronic non-communicable diseases (NCD) and adequate macro and micronutrient intake. Objective. To analyze the carbohydrate quality index (CCI) in the Costa Rican urban population and its relationship with sociodemographic and anthropometric variables and the quality and diversity of the diet. Materials and methods. Data come from the Latin American Nutrition and Health Study (ELANS), in a representative sample of 798 people between 15 and 65 years of age who reside in urban areas of Costa Rica (2014-2015). During a home visit, a questionnaire was administered to collect sociodemographic data, and participants were measured and weighed. Dietary intake was obtained through two 24-hour recalls in non- consecutive days. The CQI was calculated using fiber intake, glycemic index, liquid/solid carbohydrate ratio, and whole grain/total grains. CCI was then compared according to sex, age-group, socioeconomic level, nutritional status and diet quality and diet diversity. Results. The CQI was positively associated with energy intake, total carbohydrates, proteins, fats, cholesterol, fruits, vegetables, and legumes (p<0,001). Also, CQI was associated with a higher percentage of micronutrient adequacy and diet quality and diversity (p<0,001), as well as with a lower body mass index and lower waist circumference when adjusting for sex and age (p<0,005). Conclusions. The present study showed that higher CQI is associated with better dietary and body mass index, which shows that it is essential to establish dietary guidelines for public health in Costa Rica that allows increasing the quality of carbohydrates in the diet to contribute to the prevention of chronic NCD(AU)

ABSTRACT

En el presente estudio se evalúa la incorporación de cáscaras de zanahoria como ingrediente en galletas en diferentes concentraciones, de esta manera se pueden disminuir los desperdicios además de aprovechar nutrientes, compuestos bioactivos y fibra dietética de las cáscaras. Se recolectaron cáscaras de zanahorias, se lavaron, deshidrataron a 60°C por 24 horas y posteriormente de molieron finamente para obtener harina de cáscara de zanahoria (HCZ). Se desarrollaron galletas con la incorporación de 0, 5, 10 y 20% de HCZ en reemplazo de harina (Muestras CZ0, CZ5, CZ10 y CZ20 respectivamente). Se evaluó la preferencia y aceptabilidad sensorial de las muestras de galletas, mediante prueba de ordenamiento y escala hedónica de 9 puntos por parámetros (apariencia, color, aroma, sabor, textura, aceptabilidad general) respectivamente. También se evaluó la saciedad producida por su consumo mediante "Cociente de Saciedad" (CS) que utiliza la Escala Visual Análoga (EVA) para cuantificar el estado de saciedad en diferentes tiempos. Se determinó el contenido de fibra dietética (FD) en la HCZ y en las muestras de galletas por método enzimático-gravimétrico. Los resultados demostraron que la muestra CZ20 logró la primera preferencia sensorial y la mayor aceptabilidad sensorial en forma significativa (p<0.05). La incorporación de HCZ en galletas produjo aumento del contenido de fibra dietética y del CS. En base a los resultados obtenidos se concluyó que la mejor opción resultó ser la galleta con 20% de HCZ, ya que sensorialmente es la de mayor preferencia y de mayor aceptabilidad, contiene más fibra dietética y provoca más saciedad.


In the present study, the incorporation of carrot peels as an ingredient in cookies in different concentrations is evaluated, in this way, waste can be reduced in addition to taking advantage of nutrients, bioactive compounds, and dietary fiber from the peels. Carrot peels were collected, washed, dehydrated at 60°C for 24 hours, and then finely ground to obtain carrot peel flour (CPF). Cookies were developed with the incorporation of 0, 5, 10, and 20% of CPF in replacement of flour (Samples CZ0, CZ5, CZ10, and CZ20 respectively). The preference and sensory acceptability of the cookies samples were evaluated using an an-Ranking test and a 9-point Hedonic Scale by parameters (appearance, color, aroma, flavor, texture, general acceptability) respectively. The satiety produced by its consumption was also evaluated through the "Satiety Quotient" (SQ) which uses the Visual Analog Scale (VAS) to quantify the state of satiety at different times. The dietary fiber (DF) content in the CPF and in the cookies samples was determined by the enzymatic-gravimetric method. The results showed that the CZ20 sample achieved the first sensory preference and the highest sensory acceptability in a significant way (p<0.05). The incorporation of CPF in cookies produced an increase in the content of dietary fiber and SQ. Based on the results obtained, it was concluded that the best option turned out to be the cookie with 20% CPF, since sensorially it is the most preferred and most acceptable, contains more dietary fiber and causes more satiety than the other samples.

ABSTRACT

Background: Apple pomace is a by-product of the fruit juice industry and comprises peel, seed, stem, and pulp tissues. This by-product contains dietary fibers, polyphenols, vitamins, and organic acids that can benefit human health and have a high potential as a dietary source. Baked products are well-known food types to humans and have a key role in feeding people worldwide. Nowadays, enriched products such as bread, cakes, and biscuits are available in stores. Different studies worldwide have been done about applying the by-products of the fruit juice industry in the bakery. Objective: This research aimed to evaluate apple peel (APE) and pulp (APU) powders separately as a partial substitute for wheat flour in cake production. Methods: Apple peel and pulp separately produced as the residual wastes of juicing were dried for 3 hours in oven (60°C). The dried pulp and peel were ground and sieved using a 60 µm mesh. In this research, chemical and physicochemical analyses were performed according to AACC (Approved Methods of the American Association of Cereal Chemists) and standard food analysis methods. Textural characteristic was analyzed by a texture analyzer (Brookfield CT3-10 Kg, US) equipped with an aluminum probe. Results: Different levels of APE and APU powders (10%, 20%, and 30 %) were used to enrich the cakes. The ash content, fat content, water adsorption capacity, and oil absorption capacity of the wheat flour were lower than APU and APE, whereas the moisture content, protein content, bulk density, and pH showed a reverse trend. Adding APU and APP to the cake formula increased total dietary fiber (TDF) from 4.14 % in the control sample to 27.71 % in the sample with 30 % apple peel powder (APE-30). The highest a* colorimetric parameter (redness) in the cake core was 3.82 in the APE-30 sample. The addition of APE and APU significantly increased the hardness, gumminess, and chewiness of the samples (p<0.05). APE-10 samples could improve the nutritional properties of the cakes without significant reduction (p>0.05) in overall acceptance compared to the control sample. Conclusion: The results of this research demonstrated that a partial replacement of the wheat flour with apple pulp and peel significantly increased the dietary fibers, especially insoluble dietary fiber, compared to the control sample. Apple pulp and apple peel powders had the potential for use in cake making as a good source of dietary fibers


Antecedentes: la pulpa de manzana es un subproducto de la industria del jugo de frutas y se compone de tejidos de cáscara, semillas, tallo y pulpa. Este subproducto contiene fibra dietética, polifenoles, vitaminas y ácidos orgánicos que pueden ser beneficiosos para la salud humana y tienen un alto potencial como fuente dietética. Los productos horneados son de tipos de alimentos bien conocidos para los seres humanos y son clave en la alimentación de las personas de todo el mundo. Hoy en día, los productos enriquecidos como pan, pasteles y galletas están disponibles en las tiendas. Se han hecho diferentes estudios en todo el mundo sobre la aplicación del subproducto de la industria del jugo de frutas en la panadería. Objetivo: El propósito de esta investigación fue evaluar los polvos de cáscara de manzana (APE) y pulpa (APU) como sustituto parcial de la harina de trigo en la producción de pasteles. Métodos: Cáscaras de manzana y pulpa producidas por separado como desechos residuales de jugos, se secaron durante 3 horas en el horno (60 °C). La pulpa seca y la cáscara fueron molidas y tamizadas usando una malla de 60 micras. En esta investigación el análisis químico y físico-químico realizado de acuerdo con el AACC (Aprobado Métodos de la Asociación Americana de Químicos del Cereales) y los métodos estándar de análisis de alimentos. La característica textural fue analizada por el analizador de textura (Brookfield CT3-10 Kg, US) equipado con una sonda de aluminio. Resultados: Se utilizaron diferentes niveles de polvos APE y APU (10, 20 and 30 %) para enriquecer los pasteles. La capacidad de absorción de ceniza, grasa, agua y aceite de la harina de trigo fue menor que la APU y APE, mientras que la humedad, la proteína, la densidad a granel y el pH mostraron una tendencia inversa. Además, APU y APE en fórmula de pastel, aumentaron la fibra dietética total (TDF) de 4.14 % en la muestra de control a 27.71 % en la muestra con un 30 % de polvo de pelar de manzana (APE-30). El parámetro más alto a* colorimétrico en núcleo de pastel fue de 3.82 (enrojecimiento) en la muestra APE-30. La adición de APE y APU aumentó significativamente la dureza, gomosidad y masticabilidad de las muestras (p<0.05). Las muestras de APE-10 podrían mejorar las propiedades nutricionales de los pasteles sin reducción significativa (P<0.05) en aceptación general, en comparación con la muestra de control. Conclusión: Los resultados de este estudio demostraron que un reemplazo parcial de la harina de trigo por pulpa de manzana y cáscara aumentó significativamente la fibra dietética especialmente la insoluble, cuando se compara con la muestra de control. La pulpa en polvo y la cáscara de manzana tienen el potencial de uso en la fabricación de pasteles como una buena fuente de fibra dietética.

ABSTRACT

RESUMEN La chía (Salvia hispanica L.) es una semilla originaria de la zona sur de México y Guatemala, que se ha expandido a otros países de latinoamérica. Esta semilla ha sido utilizada con diferentes fines a lo largo de la historia, donde se destaca como producto alimentario debido a su gran versatilidad, ya que puede ser utilizada como semilla, harina integral, fracciones de fibra y/o proteína y aceite. En la actualidad, la investigación de nuevas fuentes alimentarias que otorguen beneficios a la salud ha logrado recopilar información sobre la composición química y valor nutricional de esta semilla y sus derivados (harina y aceite), donde se encuentra principalmente el contenido de ácidos grasos poli-insaturados n-3, destacando el ácido alfa linolénico (C18:3n-3, ALA), que se propone como fuente alternativa de este nutriente a alimentos de otros orígenes, además el contenido de fibra de la chía, principalmente fibra insoluble. En cuanto a los beneficios que se asocian al consumo de chía, se ha visto que tiene estrecha relación con enfermedades crónicas no transmisibles como dislipidemia, diabetes, hipertensión, cáncer, entre otras, logrando captar la atención de investigadores para controlar y prevenir estas patologías que van en aumento en la población mundial. Por lo tanto, se hace relevante profundizar en los conocimientos disponibles sobre esta semilla y sus subproductos para poder establecer los posibles mecanismos moleculares que están involucrados en la generación de beneficios para la salud. El objetivo de esta revisión es presentar una actualización de los beneficios asociados al consumo de semilla de chía y sus derivados.


ABSTRACT Chia (Salvia hispanica L.) is a seed native to the southern part of Mexico and Guatemala, which has spread to other Latin American countries. This seed has been used for different purposes throughout history, where it stands out as a food product due to its great versatility, since it can be used as a seed, whole meal flour, fiber and/or protein fractions and oil. Currently, the investigation of new food sources that provide health benefits has managed to collect information on the chemical composition and nutritional value of this seed and its derivatives (flour and oil). For polyunsaturated fatty acid content, n-3 is found, highlighting alpha linolenic acid (C18:3n-3, ALA), which is proposed as an alternative source of this nutrient to foods of other origins. In addition, the fiber content of chia, is mainly insoluble fiber. Regarding the benefits associated with chia consumption, it is closely related to chronic non-communicable diseases such as dyslipidemia, diabetes, type II, hypertension, cancer, among others, managing to attract the attention of researchers to control and prevent these pathologies that are increasing in world population. Therefore, it is relevant to deepen the knowledge available about this seed and its by-products in order to establish the possible molecular mechanisms that are involved in generating health benefits. The objective of this review is to present an update on the benefits associated with consumption of chia seed and its derivatives.

ABSTRACT

The objective of this work was to develop cookies using sorghum, germinated millet and chia flours. Four formulations (F) were used: F-sorghum (100% sorghum flour); F-Sorghum + chia (50% sorghum flour and 50% chia flour), F-millet (100% millet flour) and F-millet + chia (50% millet flour and 50% chia flour). The germinated millet flour was submitted to microbiological analysis. All cookies were evaluated in relation to chemical and sensory analyses, according to AOAC and hedonic nine-point scale, respectively. The statistical analysis was performed by the variance analysis and Tukey test at 5% probability. The F-millet formulation showed the least humidity content (4.59 ± 0.25g/100g), while chia containing cookies showed lesser concentrations of carbohydrates (F-sorghum + chia: 44.35 ± 4.34g/100g and F-millet + chia: 41.03 ± 1.40g/100g) and higher ash content (F-sorghum + chia: 3.80 ± 0.02g/100g and F-millet + chia: 3.42 ± 0.24g/100g) and of protein (F-sorghum + chia: 15.38 ± 0.44 g/100g and F-millet + chia: 18.06 ± 0.53 g/100g). The caloric value and the lipids content did not differ among formulations. The sensory analysis had 57 evaluators. The cookies produced with chia and germinated millet had higher rates for flavor, texture and general impression. In general, all tested biscuits had good sensory acceptance and nutritional quality being an alternative to increase the consumption of bioactive compounds and antioxidants(AU)

ABSTRACT

ABSTRACT BACKGROUND: Diverticulitis is an acute inflammatory process that affects individuals with diverticular disease. Given the sharp increase in the diagnostic rate of such a pathological process, there was also an increased interest in elucidating the possible causes related to the development of this clinical condition. Among the main factors investigated, diet excels, the object of study of this integrative literature review. METHODS: After searching the virtual health library and PubMed databases, five prospective cohort studies were selected that best answered the guiding question: "Is there a relationship between diet and the incidence of diverticulitis?". RESULTS: It was observed that the high intake of red meat and the low intake of dietary fiber were the most strongly associated dietary factors with the incidence of this inflammatory process. CONCLUSION: Therefore, it is evident that choosing healthy eating habits can considerably reduce the incidence of diverticulitis and, consequently, potentially more serious complications directly related to it.


RESUMO CONTEXTO: A diverticulite é um processo inflamatório agudo que afeta indivíduos com doença diverticular. Diante do acentuado aumento da taxa diagnóstica desse processo patológico, também houve o aumento do interesse em elucidar as possíveis causas relacionadas ao desenvolvimento dessa condição clínica. Entre os principais fatores investigados, destaca-se a dieta; objeto de estudo desta revisão integrativa da literatura. MÉTODOS: Após pesquisa nas bases de dados da biblioteca virtual em saúde e PubMed, foram selecionados cinco estudos de coorte prospectivos que melhor responderam à questão norteadora "Há relação entre dieta e incidência de diverticulite?". RESULTADOS E CONCLUSÃO: Observou-se que o alto consumo de carnes vermelhas e o baixo consumo de fibra alimentar são os fatores dietéticos mais fortemente associados à incidência desse processo inflamatório. Fica evidente, portanto, que a escolha de hábitos alimentares saudáveis pode reduzir consideravelmente a incidência de diverticulite e, consequentemente, de possíveis complicações mais graves diretamente relacionadas a ela.

Resumen Antecedentes: la asociación del alto consumo de carnes rojas procesadas con el cáncer colorrectal hace que los consumidores empiecen a demandar productos cárnicos con un perfil nutricional mejorado. Objetivo: diseñar una carne de hamburguesa comercializable, a base de pechuga de pollo, fuente de fibra y baja en grasa con buena aceptación por los consumidores. Materiales y métodos: con base en una formulación estándar de hamburguesa, se hicieron tres formulaciones con adición de fibra como reemplazante de grasa: F1 contenía fibra de cidra (Sechium edule); F2, de zanahoria (Daucus carota); y F3, de inulina. Se calculó la composición nutricional teórica y se realizó una prueba de aceptación por consumidores con una escala de nueve puntos. Resultados: la formulación más aceptada y con mayor contenido de fibra fue la que contenía inulina, con un puntaje de 7,7±1,4 y diferencias significativas, según la prueba T3 de Dunett, con las formulaciones F2 (p=0,001) y F1 (p=0,000), cuyos promedios de aceptación fueron similares: 6,0±2,5 puntos para F2 y 5,9±2,2 para F1 (p=0,931). Las formulaciones con fibra contenían menos grasa y calorías que la formulación control. Conclusión: es posible lograr derivados cárnicos con reducción del contenido de grasa y aporte de fibra sensorialmente aceptados.


Abstract Background: The association between increased consumption of processed red meat and colorectal cancer has driven the demand for meat products with improved nutritional profiles. Objective: To design commercialized hamburger meat that contains chicken breast as the base, fiber, reduced fat, and is accepted by consumers. Materials and Methods: Three formulations were created with a standard hamburger base and additional fiber as a fat replacement: F1 contained fiber from citron (Sechium edule); F2, from carrots (Daucus carota); and F3 from inulin. The theoretical nutritional composition was calculated and a consumer acceptance test was performed on a scale of nine points. Results: The most accepted formulation by consumers with the highest fiber content was the hamburger containing inulin, rated at 7.7±1.4 points. According to the Dunett T3 test, significant differences were reached by F1 (p=0.000) and F2 (p=0.001). They also had similar acceptance averages: F1 (5.9±2.2 points; p=0,000) and F2 (6.0±2.5 points; p=0.001) (p=0.931). The formulations containing added fiber were lowest in fat and calories when compared to the control formulation. Conclusion: It is possible to achieve meat derivatives with reduced fat and added fiber that are sensorily accepted by consumers.

Os tratamentos foram distribuídos em esquema fatorial 2x4 + ração referência, sendo uma RR sem adição de RSF e quatro tratamentos experimentais com 10%, 20%, 30% e 40% de inclusão do RSF e a suplementação ou não com carboidrases. A composição química encontrada para o RSF, na MN, foi de 89,86% de matéria seca, 0,98% de proteína bruta, 3519kcal kg-1 de energia bruta, 0,19% de extrato etéreo, 27% de fibra em detergente neutro, 19,5% de fibra em detergente ácido, 0,33% de cálcio, 0,43% de fósforo, 0,46% de potássio e 0,12% de magnésio. O uso de carboidrases proporcionou um aumento de 173 e 213kcal kg-1 nos valores de EMA e EMAn, respectivamente, resultando em 1828kcal kg-1 EMA e 1840kcal kg-1 EMAn. Concluiu-se que os maiores níveis de EMA e EMAn foram encontrados para o nível de inclusão médio do RSF de 35% e que a suplementação enzimática pode promover aumento desses parâmetros em até 12% em dietas para frangos de corte na fase de crescimento.(AU)


The energetic values and the bromatological composition of the dry residue of cassava (DRC) were determined for growing broilers with or without carbohydrase enzymes. The treatments were distributed in a 2x4 + reference diet factorial scheme, with one RD without addition of DRC and four experimental treatments with 10, 20, 30 and 40% inclusion levels of RSF and supplementation or not with carbohydrases. The chemical composition found for DRC in natural matter was 89.86% dry matter, 0.98% crude protein, 3519kcal kg-1 gross energy, 0.19% ether extract, 27% neutral detergent fiber, 19.5% of acid detergent fiber, 0.33% of calcium, 0.43% of phosphorus, 0.46% of potassium and 0.12% of magnesium. The use of carbohydrase resulted in an increase of 173 and 213kcal kg-1 in EMA and EMAn values, respectively, resulting in 1828kcal kg-1 EMA and 1840kcal kg-1 EMAn. It was concluded that the highest levels of AME and AMEn were found for the mean inclusion level of the DRC of 35% and that enzymatic supplementation may promote the increase of these parameters by up to 12% in broiler diets in the growth phase.(AU)

ABSTRACT

La enfermedad diverticular corresponde a una condición habitual en el territorio occidental, siendo el hallazgo más frecuente en población de zonas urbanizadas. Respecto a su origen, se ha planteado la influencia de factores ambientales y genéticos, incluyendo en su etiología una inadecuada ingesta de fibra dietética, disbiosis de la microbiota intestinal y niveles alterados de vitamina D. A su vez, la enfermedad diverticular sintomática no complicada (EDNC) corresponde a un tipo de diverticulosis crónica cuyas características asemejan al síndrome de intestino irritable, lo que resalta la importancia en la comprensión de esta condición. Recientemente, se ha discutido la forma en que se aborda la enfermedad diverticular y en el siguiente escrito se expondrá evidencia sobre la patogénesis y su actual manejo.


Diverticular disease corresponds to a habitual condition in the western territory, being frequently found among the population of urban areas. Regarding its origin, the influence of environmental and genetic factors, including the etiology of dietary fiber intake, intestinal microbiota dysbiosis and altered levels of vitamin D have been recognized. Symptomatic uncomplicated diverticular disease corresponds to a type of chronic diverticulosis whose characteristics resemble irritable bowel syndrome, highlighting the importance of understanding this condition. Recently, the treatment of the disease has been discussed and the following review presents evidence on pathogenesis and its management.

ABSTRACT

RESUMEN La fibra dietética ayuda a reducir el riesgo de padecer algunas enfermedades crónicas, a pesar de esto, su ingesta mundial es menor que los niveles recomendados. Este hecho motiva a la industria alimentaria a incorporar fibra dietética, obtenida de fuentes vegetales en productos alimenticios, como el yogurt. El presente estudio tuvo como objetivo evaluar las principales características de calidad de diferentes formulaciones de yogurt, en función de la incorporación de epicarpio de maracuyá deshidratado (EMD), con alto contenido de fibra dietaria (71,4 ± 0,04%), en concentración de 0 y 0,5% y el efecto que ejerce la grasa láctea presente en la leche cruda de vaca, en concentración de 0, 0,5 y 3,0%. Algunas propiedades fisicoquímicas, tales como pH, acidez titulable (%), viscosidad (cP) y parámetros de color por método CIELab fueron evaluadas en seis formulaciones diferentes. De acuerdo con los resultados obtenidos, se realizó un análisis sensorial y se evaluó la estabilidad de dos formulaciones de yogurt, durante un periodo de almacenamiento de 29 días, a 4°C. La incorporación de EMD contribuyó significativamente al incremento de acidez y la viscosidad en el producto. El EMD favoreció la estabilidad del gel y permitió obtener resultados aceptables en atributos sensoriales hasta el día 15 de almacenamiento. La incorporación de EMD en la elaboración de yogurt permitió enriquecer el valor, debido al aporte de fibra dietaria, la cual, puede actuar como sustituto funcional de la grasa láctea.


ABSTRACT Dietary fiber helps to reduce the risk of suffering from some chronic diseases. Despite this, the global average intake of this component is still lower compared to the recommended levels. This fact has motivated to the food industry to incorporate dietary fiber obtained from vegetable sources in food products. The aim of the present study was the evaluation of the main quality characteristics of different yogurt formulations, as the function of the incorporation of dehydrated passion fruit epicarp with a high dietary fiber content (71,4 ± 0,04%), and concentrations of 0 - 0,5% and the effect of dairy fat present in raw cow milk in concentrations of 0, 0,5 and 3,0%. Some physical-chemical properties such as pH, acidity (% of lactic acid), viscosity (cP) and color parameters by use of CIELab system method were evaluated in 6 different formulations. According to the results, a sensorial analysis was conducted and the stability of two yogurt formulations was determined during a storage period of 29 days at 4°C.The incorporation of EMD significantly contributed to the increase of the acidity and viscosity of the product. EMD favored the stability of yogurt gel and allowed to obtain acceptable results in sensorial attributes until day 15 of storage. The incorporation of EMD in the elaboration of yogurt, allowed the enrichment of the nutritional value due to the contribution of dietary fiber, which can act as a functional substitute of dairy fat.

ABSTRACT

Abstract Objectives: Evaluate the effect of combinations of green banana biomass and laxatives in children and adolescents with chronic constipation. Methods: This was a randomized study of 80 children and adolescents with functional constipation according to the Rome IV Criteria, who were divided into five groups: (1) green banana biomass alone; (2) green banana biomass plus PEG 3350 with electrolytes; (3) green banana biomass plus sodium picosulfate; (4) PEG 3350 with electrolytes alone; and (5) sodium picosulfate alone. Primary outcome measure was the reduction of the proportion of patients with Bristol Stool Form Scale ratings 1 or 2. Secondary outcome measures were: increase of the proportion of >3 bowel movements/week and reduction of the proportion of fecal incontinence, straining on defecation, painful defecation, blood in stool, abdominal pain, and decreased laxative doses. Results: On consumption of green banana biomass alone, a statistically significant reduction was observed in the proportion of children with Bristol Stool Form Scale rating 1 or 2, straining on defecation, painful defecation, and abdominal pain. Conversely, no reduction was observed in fecal incontinence episodes/week, blood in stool, and no increase was observed in the proportion of children with >3 bowel movements/week. The percentage of children who required decreased laxative dose was high when green banana biomass was associated with sodium picosulfate (87%), and PEG 3350 with electrolytes (63%). Green banana biomass alone and associated with laxatives was well tolerated, and no adverse effects were reported. Conclusion: Green banana biomass is advantageous as an adjunct therapy on functional constipation, mainly for reducing doses of laxatives.


Resumo Objetivos: Avaliar o efeito das combinações da biomassa de banana verde e laxantes em crianças e adolescentes com constipação crônica. Métodos: Estudo randomizado de 80 crianças e adolescentes com constipação funcional de acordo com os Critérios de Roma IV divididos em cinco grupos: 1) Somente biomassa de banana verde; 2) Biomassa de banana verde mais PEG 3350 com eletrólitos; 3) Biomassa de banana verde mais picossulfato de sódio; 4) PEG 3350 somente com eletrólitos e 5) somente picossulfato de sódio. O desfecho primário foi a redução da proporção de pacientes com as classificações 1 ou 2 da Escala de Bristol para Consistência de Fezes. Os desfechos secundários foram: aumento da produção de > 3 evacuações/semana e redução da proporção de incontinência fecal, esforço na defecação, defecação dolorosa, sangue nas fezes, dor abdominal e redução nas dose de laxantes. Resultados: No consumo somente de biomassa de banana verde há uma redução estatisticamente significativa na proporção de crianças com classificação 1 ou 2 da Escala de Bristol para Consistência de Fezes, esforço na defecação, defecação dolorosa e dor abdominal. Por outro lado, não houve redução nos episódios fecais/semana de incontinência, sangue nas fezes e nenhum aumento na proporção de crianças com > 3 evacuações/semana. O percentual de crianças que tiveram sua dose de laxante reduzida foi alto quando a biomassa de banana verde foi associada a picossulfato de sódio (87%) e PEG 3350 com eletrólitos (63%). A biomassa de banana verde sozinha e associada a laxantes foi bem tolerada e não houve efeitos adversos relatados. Conclusão: A biomassa de banana verde é vantajosa como uma terapia adjuvante na constipação funcional, principalmente na redução das doses de laxantes.

ABSTRACT

ABSTRACT: In order to improve nutritional and functional quality, chicken burgers were made with different amounts of chia seed (0, 2, 4 and 8%) as pork fat replacers and evaluated for the microbiological, technological and sensorial characteristics. The proximate composition and the microbiological characteristics of raw burgers were in accordance with Brazilian legislation. Higher additions of chia increased the amount of dietary fiber (up to 1.46%) and carbohydrate in the products and reduced the fat content by up to 29%. The addition of chia seed reduced the a* values and increased the h* values of the raw burgers and reduced the tenderness and degree of lipid oxidation in the cooked burgers. Lower sensory taste scores and overall acceptance were conferred on products with higher chia addition; although, the degree of acceptance of the products was high. Results of this study highlighted the potential use of chia seed in the elaboration of low fat and enriched dietary fiber burgers.


RESUMO: No intuito de melhorar a qualidade nutricional e funcional, hambúrgueres de frango foram elaborados com diferentes quantidades de semente de chia (0, 2, 4 e 8%) em substituição ao toucinho e avaliados quanto às características microbiológicas, tecnológicas e sensoriais. A composição centesimal e as características microbiológicas dos hambúrgueres crus estavam de acordo com o preconizado pela legislação Brasileira. Maiores adições de chia aumentaram a quantidade de fibra dietética (até 1,46%) e de carboidrato nos produtos e reduziu os valores de gordura em até 29%. A adição de semente de chia reduziu os valores de a* e aumentou os valores de h* da cor dos hambúrgueres crus e reduziu a maciez e o grau de oxidação lipídica nos hambúrgueres cozidos. Menores notas sensoriais de sabor e a aceitação global foram conferidas aos produtos com maior adição de chia, embora o grau de aceitação dos produtos tenha sido elevado. Os resultados deste estudo destacam o potencial de uso da semente de chia na elaboração de hambúrgueres com baixo teor de gordura e enriquecidos de fibra dietética.

ABSTRACT

Resumen Antecedentes: las disacaridasas intestinales pueden ser inhibidas o estimuladas parcialmente en presencia de fibra. Objetivo: evaluar el efecto de los residuos fibrosos de avena (Avena sativa) y caraotas (Phaseolus vulgaris) sobre la actividad in vitro de las disacaridasas intestinales. Materiales y métodos: 15 ratas Sprague Dawley se dividieron en tres grupos: un grupo control, un grupo alimentado con harina de caraota y un grupo alimentado con harina de avena, durante 21 días. Se obtuvo un homogeneizado de la mucosa intestinal que fue utilizado para la determinación de la actividad de las disacaridasas por un método enzimático, en presencia de sustrato natural y con la adición de residuos fibrosos de harina de avena y caraotas en concentración de 2,5 % (P/V). Resultados: la mayor actividad enzimática se registró en la región intestinal media para cada enzima (p<0,05). El orden de actividad enzimática en mg glucosa/mg proteína/min fue maltasa (0,149) sacarasa (0,096) y lactasa (0,014) (p<0,05). La maltasa fue inhibida en mayor medida por el residuo de caraota; la sacarasa, por el residuo de avena; y la lactasa, por ambos. Conclusiones: la adición de fibra purificada de avena y caraota produjo una disminución significativa de la actividad in vitro de las disacaridasas intestinales, especialmente en presencia del residuo de caraota.


Abstract Background: Intestinal disaccharidases can be partially inhibited or stimulated in the presence of fiber. Objective: To evaluate the effect of fibrous residues of oats (Avena sativa) and black beans (Phaseolus vulgaris) on the "in vitro" activity of the intestinal disaccharidases. Materials and Methods: 15 Sprague Dawley rats, were divided into three groups: control, fed with bean flour, and fed with oatmeal flour for 21 days. Homogenate was obtained by scraping the mucosa. The determination of enzymatic activity of the disaccharidases was measured by the enzymatic method, in the presence of its natural substrate and with addition of the fibrous residues obtained from the oatmeal and black beans, in concentration of 2.5 % (W/V). Results: The highest enzymatic activity was recorded in the middle intestinal region for each enzyme (p <0.05). The order of enzymatic activity in mg glucose / mg protein / min was maltase (0.149) sucrase (0.096) and lactase (0.014) (p<0.05). Maltase was inhibited to a greater extent by bean residue; sucrase by oat residue and lactase by both. Conclusion: The addition of purified fiber of oats and bean produced a significant decrease in the in vitro activity of the intestinal disaccharidases, especially in the presence of the bean residue.

ABSTRACT

RESUMEN Se decidió estudiar el efecto que la cocción y el congelamiento sucesivos tiene sobre contenido de almidones y el índice glicémico (IG) de un alimento a base de harina de maíz (bollo). Se elaboró el alimento y se sometió congelamiento y cocción un par de veces. El contenido de almidones se comparó con el de la harina de maíz pre-cocida y se encontraron diferencias significativas (F = 5,84; p = 0,005), con un incremento importante del contenido de almidón resistente debido a los tratamientos térmicos. Se elaboraron curvas de glicemia a una muestra de individuos sanos, a los que se dio a consumir el alimento sometido a los diferentes tratamientos y pan integral. Se encontraron diferencias significativas (F= 4,21; p= 0,034) y un IG de 67,9 para el bollo sometido a tres procesos de cocción y dos congelamientos. Indicativo de que los procesos térmicos provocaron la aparición de una proporción de almidón retrogradado equivalente a fibra dietética que puede ser beneficioso para el organismo.


ABSTRACT We studied the effect that subsequent cooking and freezing has on the starch content and the glycemic index (GI) of a corn flour-based food (bun). The food was made and exposed to cooking and freezing a couple of times. The starch content was compared with that of precooked corn flour and significant differences were found (F = 5.84; p = 0.005), with an important increase in the retrograded starch content due to thermic treatments. Glycemic response curves were conducted for a sample of healthy individuals, who consumed the food submitted to the treatments and wholegrain bread. Significant differences were found (F = 4.21; p= 0.034) and a GI of 67.9 for the bun submitted to three cooking and two freezing processes. Results suggest that the thermic treatments induced the appearance of a retrograded starch proportion equivalent to dietary fiber which could be beneficial for the body.

ABSTRACT

RESUMEN El endospermo de semilla de tara (EST) y polvo de las hojas de Agave americana (HAA) fueron evaluados como nuevas fuentes de fibra dietética teniendo como referencia al salvado de trigo (ST). Mediante experimentos in vitro se determinaron las propiedades funcionales y con experimentos in vivo, en ratas Holtzman, los efectos fisiológicos de las dietas alimentadas con 6% de fuente de fibra. El EST tuvo 32,2% de solubilidad; 45,0 g/g de capacidad de absorción; 47,9 g/g retención de agua y 46 ml/g de hinchamiento; valores significativamente superior al ST (p< 0,01). En cambio, el HAA presentó 6,38 g/g de capacidad de adsorción del aceite respecto al 5,27 del ST (p< 0,01). La dieta con EST, tuvieron 8,76% de grasa fecal, valor que supera al ST (p< 0,01). Sin embargo, no hubo efecto sobre el peso corporal de las ratas. El HAA incrementó el volumen fecal y redujo de 14,9 a 10,4 h el tiempo de tránsito intestinal (p< 0,01). El endospermo de semilla de tara, retiene la grasa de la dieta y la elimina a través de las heces; en cambio, el polvo de las hojas de Agave americana, reduce el tiempo de tránsito intestinal.


ABSTRACT The endosperm of tara seeds (EST) and powder from the leaves of Agave americana (HAA) were evaluated as new sources of dietary fiber, using wheat bran (ST) as a reference. In vitro experiments were carried out to determine functional properties and in vivo experiments were used to determine the physiological effects of fed Holtzman rats with diets with 6% of each fiber source. Endosperm of tara had 32.2% solubility, 45.0 and 47.9 g/g absorption and water retention capacity, respectively, and 46 ml/g swelling, values significantly higher than wheat bran (p< 0.01). On the other hand, Agave had higher adsorption capacity of oil than wheat bran (6.38 g/g vs. 5.27 g/g; p< 0.01). Diets with endosperm of tara, were 8.76% of fecal fat, a value that exceeded that of wheat bran (p< 0.01); however, there was no effect on body weight of the rats. Agave increased fecal volume and reduced (p< 0.01) intestinal transit time from 14.9 to 10.4 h. Endosperm of tara retained and eliminated fat from the diet through the feces; on the other hand, the powder of Agave leaves reduced intestinal transit time.

ABSTRACT

Resumen Se evaluó el efecto fisiológico del consumo de arepas de maíz enriquecidas con 10% (p/p) de pectina extraída de cáscara de curuba sobre los niveles séricos de glucosa y lípidos en adultos voluntarios. La pectina se extrajo con ácido clorhídrico y se precipitó con etanol del 96% (v/v). En primer lugar, los voluntarios consumieron arepa sin pectina por siete días; después, arepa con 10% (p/p) de pectina cítrica comercial por 20 días y, finalmente, arepa con 10% de pectina de curuba por 20 días. Al mismo tiempo, se realizó un análisis sensorial de aceptación. Los resultados mostraron que, al consumir arepa con pectina de curuba, los niveles séricos de glucosa disminuyeron significativamente (5,88% (p = 0,023)), mientras que el perfil lipídico no se afectó. La arepa con pectina de curuba mostró mayor porcentaje de fibra dietética soluble, insoluble y total, así como menor porcentaje de carbohidratos disponibles, respecto a las otras arepas analizadas. El panel sensorial dictaminó baja aceptación en sabor y textura para las arepas con pectina cítrica comercial y con pectina de curuba. Se concluyó que la pectina de curuba puede aprovecharse para la formulación de arepas ya que ofrece a los consumidores un alimento benéfico para reducir los niveles de glucosa en la sangre.


Abstract The physiological effect of corn arepas consumption enriched with 10% (w/w) pectin extracted from banana passionfruit peel was evaluated on the serum levels of glucose and lipid in adult volunteers. The pectin was extracted with hydrochloric acid and precipitated with 96% (v/v) ethanol. Firstly, the volunteers consumed arepa without pectin for seven days; then, arepa with 10% of commercial citrus pectin for 20 days, and, finally, arepa with 10% banana passionfruit pectin for 20 days. At the same time, a sensory acceptance analysis was carried out. The results showed that, when consuming arepa with banana passionfruit pectin, serum glucose levels decreased significantly (5.88% (p = 0.023)), while the lipid profile was not affected. The arepa formulated with banana passionfruit pectin showed a higher percentage of soluble, insoluble and total dietary fiber, as well as a lower percentage of available carbohydrates as compared to the other analyzed arepas. The sensory panel ruled low acceptance in flavor and texture for arepas with commercial citrus and banana passionfruit pectin. It was concluded that banana passionfruit pectin can be used for the formulation of arepas since it offers to consumers a beneficial food to reduce blood glucose levels.

Primeiro, os voluntários consumiram arepa sem pectina por sete dias, então arepa com 10% de pectina cítrica comercial por 20 dias, e finalmente arepa com 10% de pectina de curuba por 20 dias. Paralelamente, foi realizado uma análise sensorial de aceitação. Os resultados encontrados mostram que ao consumir arepa com pectina de curuba os níveis séricos de glucose diminuíram significativamente (5,88% (p = 0,023)), enquanto que o perfil lipídico não foi afectado. A arepa com pectina de curuba mostrou maior percentagem de fibra dietética solúvel, insolúvel e total, e um menor percentagem de carboidratos disponíveis com respeito aos valores das outras arepas avaliadas. O painel sensorial mostrou baixa aceitação no sabor y textura para arepas com pectina cítrica comercial e de curuba. Concluiu-se que a pectina de curuba pode ser usada para a formulação de arepas, uma vez que oferece aos consumidores um alimento benéfico para reduzir os níveis de glucose no sangue.

ABSTRACT

The objective of this study was to determine the proximal composition, the physical and chemical characteristics and the in vitro antioxidant capacity (DPPH, ABTS and FRAP) of the pulp of the wild passion fruit (Passiflora glandulosa Cav.) from Cariri region, Ceara, Brazil. The results showed that the proximal composition and the caloric value of this passion fruit are similar to other species, but with a high ascorbic acid content. The fruit pulp showed low level of antioxidant activity and low level of polyphenolic compounds followed by three methodologies used. Due to high levels of titratable acidity (3.52) and total soluble solids (17.80° Brix), this fruit can be considered as a high value fruit for commerce. However, it is a species of passion fruit with few studies described in the literature, and more research is needed to assess its nutritional and functional potential.


O objetivo do estudo foi determinar a composição centesimal, as características físicas e químicas e a capacidade antioxidante (DPPH, ABTS e FRAP) in vitro da polpa do maracujá-do-mato (Passiflora glandulosa Cav.) da região do Cariri, Ceará, Brasil. Os resultados demonstraram que a composição centesimal e o valor calórico desse tipo de maracujá são similares a outras espécies, mas com nível elevado de ácido ascórbico. A polpa apresentou baixo teor de polifenóis e baixa atividade antioxidante para as três metodologias aplicadas. Em razão dos altos níveis de acidez titulável (3,52) e sólidos solúveis totais (17,80° Brix), este fruto pode ser considerado como um fruto de alto valor para o comércio. Porém, esta é uma espécie de maracujá pouco descrita na literatura, sendo necessárias mais análises para avaliar seu potencial valor nutricional e funcional.

ABSTRACT

This research assessed the proportion of whole-wheat flour in whole-wheat bread relative to the level mandated by law, as well as the content of lipids (Lip) and sodium (Na) in French bread, and of Lip, Na and total dietary fiber (TDF) in whole-wheat bread made in bakeries in Montevideo and Canelones, Uruguay. The percentage ofNa and TDF using both Adequate Intakes (Als) and Tolerable Upper Intake levels (Uls) were estimated in reference to recommended daily quantities. Na in French bread consists of 64% of AIs for individuals aged nine and older, and over 100% of AIs for adults aged 51 and older. Whole-wheat bread values are slightly lower. TDF consists of 38% of AIs in 9 year-old children and 53% in adults older than 50 years of age. This work helps to establish a baseline for the development of formulations with minimum levels of Na and optimum levels of TDF in artisan bread.


La presente investigación evaluó la proporción de harina integral en pan integral con el nivel legislado; el contenido de lípidos y sodio (Na) en pan francés y lípidos, Na y fibra dietética total (FDT) en pan integral elaborado en panaderías de Montevideo y Canelones. Se estimó según cantidades diarias recomendadas el porcentaje de Na y FDT en relación a las Ingestas Adecuadas (AIs) y los Límites Máximos Tolerables (Uls). El Na en pan francés cubre desde los 9 años un 64% de las IAs hasta cerca del 100% en adultos desde los 51 años; el pan integral alcanza valores algo inferiores. La FDT cubre en niños de 9 años el 38% de las IAs y 53% en adultos mayores de 50 años. Este trabajo contribuye a disponer de una línea de base para el desarrollo de formulaciones con mínimos niveles de Na y óptimos de FDT en panes artesanales.

ABSTRACT

O presente estudo teve como objetivo avaliar o os padrões de fermentação microbiana do ceco de suínos, utilizando-se um modelo aplicado na técnica in vitro de produção de gases para ruminantes. Três tipos de inóculo foram utilizados: ceco de suínos criados ao ar livre (CSF), ceco de suínos criados confinados (CSC) e líquido ruminal de bovino (LRB). Os substratos utilizados derivaram de uma dieta de suínos à base de farelo de soja e de grãos de milho, atendendo as exigências nutricionais dos suínos. Para composição dos substratos, foram estabelecidos diferentes níveis de substituição da dieta basal pela torta da amêndoa da Acrocomia aculeata (AA), coproduto da produção do biodiesel, sendo: BAS - 100% de dieta basal; M10 - 90% de dieta basal e 10% AA; M20 - 80% de dieta basal e 20% AA e o TF - feno de Tifton 85 (Cynodon spp.). A produção de gases foi avaliada nos tempos zero, três, seis, nove, 12, 16, 24, 48, 72 e 96 horas após a incubação. Foram analisados o potencial máximo de produção de gás (A) e o tempo de colonização (L). O delineamento experimental utilizado foi inteiramente ao acaso, em arranjo fatorial 4 x 3. Os dados de A e L foram submetidos à análise de variância, e as médias comparadas pelo teste de Tukey a 5%. Comparando os inóculos para A (mL/gMS), LRB e CSF apresentaram valores similares, diferindo apenas para TF. O tempo de colonização (L) entre inóculos, o CSC e o CSF apresentaram os menores tempos de colonização quando a ração foi BAS. Com os substratos M10 e M20, o inóculo LRB apresentou o menor tempo, CSF o maior tempo e CSC não diferiu de ambos. Não houve diferença significativa entre os inóculos para o substrato TF. A técnica de produção de gases utilizada para o ceco de suínos apresentou resultados semelhantes aos encontrados para ruminantes. O modelo matemático usado foi adequado para descrever a curva de fermentação no ceco de suínos, mostrando semelhanças entre as microbiotas do ceco e do rúmen.(AU)


This study aimed to evaluate the microbial fermentation patterns of the pig ceca using the technique of in vitro gas production for ruminants. Three types of inoculums were used: swine ceca raised in a free range system (CSF), swine ceca raised in a conventional confined system (CSC) and bovine rumen fluid (LRB). The substrates used were derived from pig's diet with soybean meal and corn grits, according to the nutritional requirements of swine. The substrates were composed by different set levels of substitution of basal diet by meal almond Acrocomia aculeata (AA), as: BAS - 100% of basal diet; M10 - 90% of basal diet and 10% AA (M10); M20 - 80% of basal diet and 20% AA (M20) and TF - Tifton 85 hay (Cynodon spp.).The gas production was evaluated at times 0, 3, 6, 9, 12, 16, 24, 48, 72 and 96 hours after incubation. The study analyzed the maximum potential of gas production (A) and lag time (L). The experimental design was completely randomized in a 4 x 3 factorial arrangement. The A and L data were submitted to analysis of variance and the averages compared by Tukey 5% test. Comparing the inoculum for A (ml / gDM), LRB, and CS, they showed similar values, differing only for TF. The lag time (L) between inoculum, the CSC and CSF had the lowest colonization times when the meal was BAS. With M10 and M20 substrates, the LRB inoculum showed the lowest time, CSF had the longest time and CSC did not differ from both. There was no significant difference between the inoculum for TF substrate. The gas production technique used for the ceca of pigs showed similar results to those for ruminants. The mathematical model used was adequate to describe the fermentation curve in the ceca of pigs, showing similarities between the microbiota of the ceca and the rumen.(AU)
