RESUMO

The relationship between the consumption of hyper-palatable ultra-processed foods and the process of addiction gains notoriety due to its relationship with obesity. Food addiction is a complex phenomenon intrinsically related to the individual's behavioral, emotional, and subjective aspects. Therefore, using classical approaches to sensory science may be insufficient to understand better the individual's sensory experience with hyper-palatable foods. In this context, sensory and consumer science techniques with holistic approaches have been aimed at accessing more subjective consumer perceptions. This study used the Yale Food Addiction Scale (YFAS 2.0) to investigate the prevalence of food addiction and the Structured Projective Mapping (S-MP) and Sorting techniques to verify how individuals with and without food addiction perceive and understand different types of food. The prevalence of food addiction was 21.77% (n = 59 out of 271) and was associated with a higher BMI but not with sociodemographic aspects. Projective Mapping (RV = 0.937) and Sorting (RV = 0.934) indicated that perception in relation to attributes such as health and pleasure was similar for all investigated foods in individuals with or without food addiction. The presence of addictive eating behavior does not seem to be related to the way individuals perceive foods from different categories, for example, minimally or highly processed and hyper-palatable foods.

RESUMO

Thermal processes can be very damaging to the nutritional and sensory quality of foods. Non-thermal technologies have been applied to reduce the impact of heat on food, reducing processing time and increasing its efficiency. Among many non-thermal technologies, cold plasma is an emerging technology with several potential applications in food processing. This technique can be used to preserve and sanitize food products, and act as a pre-treatment for drying, extraction, cooking, curing, and hydrogenation of foods. Furthermore, the reacting plasma species formed during the plasma application can change positively the sensory and nutritional aspects of foods. The aim of this review is to analyze the main findings on the application of cold plasma as a pre-treatment technology to improve food processing. In its current maturity stage, the cold plasma technology is suitable for reducing drying time, increasing extraction efficiency, as well as curing meats. This technology can convert unsaturated into saturated fats, without forming trans isomers, which can be an alternative to healthier foods. Although many advantages come from cold plasma applications, this technology still has several challenges, such as the scaling up, especially in increasing productivity and treating foods with large formats. Optimization and control of the effects of plasma on nutritional and sensory quality are still under investigation. Further improvement of the technology will come with a higher knowledge of the effects of plasma on the different chemical groups present in foods, and with the development of bigger or more powerful plasma systems.

RESUMO

Milk and dairy products present considerable socioeconomic importance but are also a regular pesticide residue contamination source, which is considered a worldwide public health concern and a major international trade issue. Thus, a literature review was conducted to assess pesticide residue levels in milk and dairy products, as well as the residue degradation capacity during its processing. Organochlorine, organophosphate, synthetic pyrethroid and/or triazine were found in fluid milk, powder products, yogurts, cheese, butter, and sour cream. Thermal processing reduced most residue levels, although some treatments increased total hexachlorocyclohexane and its isomers (α-, γ-, δ-, and ß-). Emerging non-thermal treatments presented promising results, but some by-products had higher toxicity than their precursors. Biodegradation by lactic acid bacteria were effective during yogurt and cheese fermentation. However, ß-hexachlorocyclohexane level seems to increase in yogurts containing Lactobacillus acidophilus and Bifidobacterium animalis subsp. lactis, while increase or maintenance of pesticide residue concentration was observed during coagulation and cheese maturation. Deep research is needed to understand the isomerization and degradation mechanisms after thermal, non-thermal, and fermentation processing. Emerging heat technology can be an excellent topic to be investigated for pesticide residues degradation in the future. These mitigation approaches can be a feasible future alternative to milk and dairy production.

RESUMO

Freeze concentration technology is applied to concentrate liquid foods at low temperatures, thus separating pure ice crystals from the final concentrate solution. This method is an interesting alternative to concentrate food with high water levels and significant nutritional value such as dairy products, since several bioactive compounds are reduced when exposed to elevated temperatures. Considered that, this technique may be a great alternative to concentrating and maintaining both nutritional and sensory characteristics of liquid foods. The present review aims to introduce freeze concentration procedures as an eligible choice for conserving dairy products', also addressing its effects on the dairy matrix. PRACTICAL APPLICATION: This study reports the main techniques of freeze concentration applications in dairy products, to be used both on an industrial and laboratory scale, aiming to improve the nutritional quality of the products obtained.

RESUMO

Prato cheese is one of the most consumed dairy products around the word, mainly in Brazil, being the second most produced cheese in the country. However, a great variation in the cheeses sensory profiles is observed. Therefore, knowledge about the attributes that drives the product acceptance is important for Prato cheese standardization, targeting the best production conditions for obtaining cheese quality improvement. Moreover, this study also contributes with information about the TDS and CATA methodologies for the sensory field. TDS and CATA were useful tools determining liking directors of Brazilian Prato cheese. Creamy, Salt and soft attributes were indicated as drivers of liking of Prato cheese, while hard, rubbery and bitter taste contributed negatively to the acceptance of the product.

RESUMO

The objective of this study was to assess the perceptions (using the preferred attribute elicitation [PAE] methodology) and acceptance of frozen dessert processed with water-soluble extract of rice byproduct and added with prebiotic components (long-chain inulin, medium-chain inulin, oligofructose, or polydextrose, 5 g/100 g) by vegan or nonvegan consumers. Most of the elicited attributes (9 out of 13 attributes, yellow color, brightness, creamy appearance, passion fruit aroma, sweet taste, passion fruit flavor, acid taste, sour taste, and creamy texture) were considered important for the characterization and/or acceptance of the frozen dessert formulations by both groups (vegan and nonvegan), but the order of importance was different between the groups. The sensory profile (Rv = 0.48, P = 0.03 in MFA) of the frozen dessert formulations was similar between vegan and nonvegan groups, and polydextrose contributed to increase firmness/consistency of the frozen dessert, while long-chain inulin contributed to the increase in the creaminess of the products. Finally, oligofructose and polydextrose could reduce the sour taste of the products. The consumers gave scores from 6 to 8 in a 9-point hedonic scale for the products, suggesting suitable acceptance. However, vegan consumers gave lower scores for the same products. In conclusion, PAE methodology can be used to compare the perception of different consumer groups, and vegan and nonvegan consumers have a similar perception about prebiotic frozen dessert processed with water-soluble extract of rice byproduct. Furthermore, the frozen dessert developed had suitable consumer acceptance, although vegan gave lower scores than nonvegan consumers. PRACTICAL APPLICATION: This is the first study involving the development of prebiotic frozen dessert from water-soluble extract of rice byproduct and application of PAE to assess the sensory perception of vegan and nonvegan consumers. The results are important for the industry as they indicate that the PAE methodology can be used to characterize food products, compare the perception of different consumer groups, and elicit attributes that are important for the products, suggesting that universal marketing strategies could be used and that the developed frozen dessert could serve both vegan consumers and those on conventional diets.

RESUMO

Temporal Dominance of Sensations (TDS) and Temporal Check-all-that-apply (TCATA) are fast and dynamic descriptive techniques for sensory characterization of food. The temporal perception involved during the consumption of reformulated meat products are rarely considered and, in this context, the aim of the present work was to evaluate the influence of salt and fat reduction on Bologna sausage with addition of emulsion gel in the dynamic sensorial perception by using TDS and TCATA methods considering overall liking. After the dynamic sensory characterization tasks, consumers rated their liking using a 9-point hedonic scale. The findings showed that fat and salt reduction, and the addition of emulsion gels as fat replacers affected the sensory characteristics of the Bologna sausages. Regarding the methods, both studies collected the variations between samples with a great correlation between data. The TDS and TCATA curves revealed that texture attributes (firm and soft) were dominant at the beginning of the evaluation for all samples. TCATA also showed that juicy was dominant in the first 15 s of eating period. Related to overall liking, control sample (2% salt and 20% pork back fat) presented the highest scores (7.25 for TDS and 7.24 for TCATA) and Bolognas sausages with emulsion gels and reduced in salt were less accepted (4.95 for TDS and 5.86 for TCATA). Bologna flavor was the major attribute related to liking and fat flavor the main driver of disliking. Results from the present work suggest that dynamic sensorial methods are effective tools to characterize reformulated meat products.

RESUMO

The aim of this study was to investigate the influence of hi-maize, inulin, and rice bran in the survival of Lactobacillus acidophilus LA-5 in pectin microparticles obtained by internal gelation and subjected to freeze-drying. For this, the development of a matrix capable of extending Lactobacillus acidophilus viability to develop new functional foods was emphasized. Microparticle size, encapsulation efficiency, probiotic survivability after gastrointestinal simulation, and storage stability were analyzed. The pectin + inulin encapsulation matrix presented the highest encapsulation efficiency (68.1%) compared to the other treatments. Microparticle sizes ranged from 166 ± 2 µm (pectin + hi-maize) to 345 ± 9 µm (pectin + inulin). The microparticles added from the different prebiotics showed better microorganism protection when compared to treatment without prebiotics, which presented greater viability in the gastrointestinal simulation. Under storage conditions of 25 °C and -18 °C, the microparticles containing hi-maize, inulin, and rice bran maintained the probiotic microorganisms viable for longer periods than the pectin microparticles. At 7 °C, the pectin + rice bran treatment stood out from the other treatments, as it was able to maintain probiotic stability during 120 days of storage.

RESUMO

Lactobacillus acidophilus were encapsulated by complex coacervation followed by transglutaminase crosslinking, aiming to improve the resistance of the microcapsules and improve the protection for probiotics. Subsequently, microcapsules were dried by freeze drying. The encapsulation efficiency, morphology, thermal resistance, gastrointestinal simulation and storage stability were analysed for wet and dry forms. The treatments offered high encapsulation efficiency (68.20-97.72%). Transglutaminase maintained the structure rounded, multinucleate and homogeneous distribution of probiotics in the microcapsules. In relation to the thermal resistance, in general, microencapsulation was effective in protecting and crosslinked microcapsules demonstrated greater protection for probiotics, obtaining viable cell counts of up to 10 log CFU g-1, approximately. On exposure to the simulated gastrointestinal tract, microencapsulation coupled to crosslinking demonstrated good results and the dry form was more efficient in the protection and the treatment with greater amount of transglutaminase was highlighted (9.07 log CFU g-1). As for storage, probiotic viability was maintained for up to 60 days in freezing temperature, with counts of up to 9.59 log CFU g-1. The results obtained in the present work are innovative and present a promising alternative for the protection of probiotics and their addition in food products.

RESUMO

O leite é um dos constituintes da dieta de crianças, adultos e idosos em todo o mundo. Neste contexto, deficiências no manejo, higiene inadequada na ordenha, equipamentos, índices elevados de mastite e mão de obra desqualificada podem prejudicar a qualidade da matéria-prima. O leite ofertado em qualidade microbiológica insatisfatória pode ser veículo de vários agentes etiológicos e doenças alimentares. O presente trabalho teve como objetivo realizar a avaliação microbiológica do leite produzido no município de Valença – RJ, através da quantificação de bactérias heterotróficas aeróbicas mesófilas e psicrófilas. Após a análise das amostras 14,2% das propriedades encontrava-se dentro do limite aceitável pela legislação para bactérias heterotróficas aeróbicas mesófilas e 28,4% para psicrófilas, sendo o aceitável 300.000 UFC/mL.

RESUMO

A agricultura familiar é responsável por práticas produtivas mais sustentáveis e desenvolvimento local. Dessa forma, incentivos à avicultura, por intermédio da agricultura familiar, têm sido viabilizados através do Programa Rio Rural. Neste sentido, o trabalho teve por objetivo realizar o levantamento de informações que subsidiem estratégias para melhorias do sistema de produção e comercialização de ovos caipiras. Os resultados indicam que apesar de índices produtivos baixos, a maioria dos beneficiários está satisfeita com a atividade. Nota-se ainda que as práticas sanitárias são deficientes, e que os produtos comercializados, em grande parte informalmente, não seguem as condições adequadas. Conclui-se que as ações de assistência técnica devem ser ampliadas de forma que viabilizem um sistema produtivo ajustado e com bases sustentáveis.

RESUMO

Elevou-se, em escala global, a preocupação contra ações deliberadas que visem atingir a cadeia produtiva de alimentos, incluindo em ambientes militares. Neste contexto, surgiu o conceito de Food Defense (Defesa Alimentar), que determina medidas preventivas, de redução às vulnerabilidades à ataques intencionais de natureza química, física, biológica ou radiológica. Neste sentido, o presente trabalho buscou identificar, através de questionário remetido eletronicamente a empresas fornecedoras de alimentos de uma Organização Militar do Exército Brasileiro, as medidas de Food Defense adotadas. Os resultados demonstraram que apesar da conformidade na maioria dos quesitos investigados, notou-se grande vulnerabilidade dos estabelecimentos em relação ao acesso de colaboradores e visitantes, e vigilância de áreas relevantes para a atividade.

RESUMO

A remoção de um produto não conforme em posse do consumidor, voluntariamente ou através de uma chamada pública, chama-se recall. Após breve pesquisa, nota-se que os tipos e procedimentos de recall de alimentos registrados nos órgãos reguladores no Brasil são subnotificados, quando comparados aos descritos em outros países como EUA, Canadá e pertencentes à União Europeia, especialmente se verificarmos o número de casos registrados por pequenas e médias empresas de alimentos. Sendo assim, o presente trabalho teve por objetivo verificar, através da técnica qualitativa de grupo focal, a percepção a respeito do recall de alimentos, e os entraves encontrados por gestores da cadeia produtiva de alimentos para a realização deste procedimento.
