Unveiling the Aromas and Sensory Evaluation of Hakko Sobacha: A New Functional Non-Dairy Probiotic Fermented Drink.

At the dawn of a food transition encouraging the consumption of healthy and sustainable non-dairy probiotic products, the development of a fermented functional drink based on Sobacha is considered. Sobacha is an infusion of roasted buckwheat seeds widely consumed in Asian countries for its health benefits. As fermentation improves the nutritional and organoleptic status of grains, the mixed fermentation process involved in the development of kombucha beverages (fermented sweet tea) is conducted by inoculating a symbiotic culture of bacteria and yeasts into the transposable matrix (Sobacha instead of tea). Sobacha, a healthy pseudo-cereal matrix with promising aromas, could be fermented to potentially develop an innovative drink, named "Hakko Sobacha". This neologism would reveal the fermented character of the infusion, Hakko meaning fermented in Japanese. Considering the beverage characterization, the kinetics of the volatile organic compound syntheses were determined using stir-bar sorptive extraction followed by gas chromatography coupled to mass spectrometry analysis. Odor-active compounds were theoretically calculated to estimate the flavor composition. Finally, sensory analyses highlighted the appreciation and preferences of the consumer towards the beverages. The fermentative yield differences observed between the two buckwheat concentration modalities tested seemed to be correlated with the sugar and nutrient levels available from the starch (buckwheat) matrix. Having characterized Hakko Sobacha, this study proposed the possibility of developing new beverages by monitoring the fermentative process. This should enable improved control and enhancement of their sensorial properties, which could in turn lead to greater customer acceptability.

Efficacy of immune-strengthening functional drinks in top-level athletes: a questionnaire survey-based research.

PURPOSE: Functional beverages are intended to support those who want to maintain optimal physical condition and improve their quality of life through the enhancement of heart health, immunity, and digestion. The purpose of this study was to investigate the performance of top-level athletes consuming immune-strengthening conditioning nutritional drinks. METHODS: A total of 107 top-level athletes (baseball (56 players), pro volleyball (17), athletics (16), cycling (8), golf (6), and fencing (6)) participated in the experiment. They consumed an immune-enhancing functional beverage once a day for 8 weeks and responded to a survey before, during, and after drinking the beverage. RESULTS: Three total aspect-based subfactors were drawn from 24 questions in the factor analysis: physical, satisfaction with mental stability, and activity in performance. The physical, mental stability and performance changes of athletes significantly increased in period 2 (4 weeks after intake) and period 3 (after 8 weeks of intake). CONCLUSION: We evaluated the efficacy of a new conditioned beverage containing Lactobacillus B240 and protein in improving the performance and physiological utility of top athletes. This functional drink may gain popularity among those seeking health benefits and improved exercise performance.

Acute oral toxicity of a novel functional drink based on Ilex guayusa, Vernonanthura patens, and cocoa husk.

A novel functional drink with nutraceutical properties was formulated from the aqueous extracts of Ilex guayusa, and Vernonanthura patens leaves, and cocoa husks. This juice contains various bioactive compounds, such as phenolic compounds and methylxanthines, with antioxidant and stimulant properties of pharmacological interest. However, it is known whether herbal extracts' interaction may have adverse toxic effects on human health. To evaluate this functional drink's innocuity, we estimated the acute oral toxicity (AOT) in experimental mice. This paper presents the AOT evaluation of two formulations of a functional drink (pre-formulation and microencapsulation) at a single dose of 2000 mg/kg of body weight (b.w.). No signs of adverse toxicity and mortality were observed after a single oral dose of 2000 mg/kg b.w. Likewise, no significant body and organ weight changes, food and water consumption behavior, and no histopathological changes were observed in the main organs evaluated. In conclusion, this functional drink can be categorized as low toxicity " according to the Globally Harmonized Classification System (GHS), making it a potential beverage with high nutritional and pharmacological value.

Protein profile of commercial soybean milks analyzed by label-free quantitative proteomics.

The consumption of soy milk is increasing worldwide for its nutritional value and health benefits, however, its protein composition after commercialization is not well known. Technological and thermal treatments to which soy milk is subjected could affect the protein composition of the commercial products. This study compared the protein profile of 15 different commercial soy milks using a label-free quantitative proteomics approach. Proteins related to nutrient reservoir activity, endopeptidase inhibitor activity, lipid binding, and seed maturation contribute the most in terms of percentage mass. Their associated Gene Ontology terms are also enriched. Samples clustered into three groups based on their protein composition, with glycinins and beta-conglycinins being the most influential for determining the clustering. Amino acid composition estimated from the proteomics data also reflects the clustering of samples. Twenty allergenic proteins varying in abundance were identified, with Gly m 5 and Gly m 6 being the predominantly abundant allergens.

Symbiotic drink based on Brazil nuts (Bertholletia excelsa H.B.K): production, characterization, probiotic viability and sensory acceptance / Bebida simbiótica à base de castanha-do-Brasil (Bertholletia excelsa H.B.K): produção, caracterização, viabilidade probiótica e aceitação sensorial

ABSTRACT: Brazil nut is a typical oilseed from the Amazon region, of great economic and cultural importance. Due to its high nutritional value, it is interesting to be used as a matrix for new products' development. Thus, the present study aimed to develop and characterize a drink based on Brazil nuts fermented by Lactobacillus casei and added with inulin. After formulated, the drink was pasteurized, fermented, maturated, and stored under refrigeration for 28 days. Physical, chemical, microbiological, and sensory analyzes were performed before and after fermentation, at 7-day intervals. There was maintenance in the content of lipids and proteins and reduction in the concentrations of fibers, ash, total carbohydrates, and moisture. The fermented drink pH decreased significantly during storage, while the acidity and the soluble solids content increased from the 14th day. Regarding the color, there were significant changes in all parameters analyzed. In the fermented drink, the development of molds and yeasts, total and thermotolerant coliforms, and Salmonella were not verified, while the control drink deteriorated after 7 days. The probiotic L. casei had count ranging from 9.48 to 8.59 log CFU mL-1 during the 28 days. When exposed to in vitro gastrointestinal conditions, L. casei significantly reduced its concentration. However, it reached the enteric phase with counts greater than 6.00 log UFC mL-1. Sensorially, the drink reached intermediate scores (between 5.41 and 6.02). Therefore, the use of Brazil nuts proved to be viable for the development of a product free of animal-origin components, symbiotic, and of outstanding nutritional quality.

RESUMO: A castanha-do-Brasil é uma oleaginosa típica da região Amazônica, de grande importância econômica e cultural. Devido ao seu alto valor nutritivo, torna-se interessante a sua utilização como matriz para o desenvolvimento de novos produtos. Assim, o presente estudo teve como objetivo o desenvolvimento e caracterização de uma bebida à base de castanha-do-Brasil fermentada por Lactobacillus casei e adicionada de inulina. Após formulada, a bebida foi pasteurizada, fermentada, maturada e armazenada sob refrigeração por 28 dias. Foram realizadas análises físicas, químicas, microbiológicas e sensoriais antes e após a fermentação, em intervalos de sete dias. Observou-se uma manutenção no teor de lipídeos e proteínas e redução nas concentrações de fibras, cinzas, carboidratos totais e umidade. O pH da bebida fermentada reduziu significativamente ao longo do armazenamento, enquanto a acidez e o teor de sólidos solúveis aumentaram a partir do 14° dia. Em relação à cor, houve alterações significativas em todos os parâmetros analisados. Na bebida fermentada, não foi verificado o desenvolvimento de bolores e leveduras, coliformes totais e termotolerantes e Salmonella, enquanto a bebida controle se deteriorou após sete dias. O probiótico L. casei apresentou contagens variando de 9.48 a 8.59 log CFU mL-1 durante os 28 dias de armazenamento. Quando exposto às condições gastrointestinais in vitro, o L. casei diminui a sua concentração significativamente. Contudo, atingiu a fase entérica com contagens superiores a 6.00 log UFC mL-1. Sensorialmente, a bebida alcançou scores intermediários (entre 5.41 e 6.02). Dessa forma, a utilização da castanha-do-Brasil se mostrou viável para o desenvolvimento de um produto isento de componentes de origem animal, simbiótico e de destacável qualidade nutricional.

Metabolic Activity of Anthocyanin Extracts Loaded into Non-ionic Niosomes in Diet-Induced Obese Mice.

PURPOSE: Anthocyanins (ACNs) are polyphenols that might reduce pathological processes associated with type 2 diabetes mellitus and other chronic diseases, but their bioavailability is still controversial. In this study, the metabolic activity of oral delivery of ACN-loaded niosomes was investigated and evaluated in a diet-induced obesity (DIO) mice model. METHODS: ACNs extracted from Vaccinium Meridionale by the supercritical fluid extraction method were loaded in niosomes. The niosomal formulation was physically characterized and further administrated in drinking water to obese, insulin resistant mouse. We evaluated the effect of ACN loaded niosomes on hyperglycemia, glucose and insulin intolerance and insulin blood levels in C57BL/6 J mice fed with a high-fat diet. RESULTS: The ACN-loaded particles were moderately monodisperse, showed a negative surface charge and 57% encapsulation efficiency. The ACN-loaded niosomes ameliorated the insulin resistance and glucose intolerance in the DIO mice model. Additionally, they reduced animal weight and plasma insulin, glucose, leptin and total cholesterol levels in obese mice. CONCLUSION: ACN-loaded niosomes administration, as a functional drink, had a beneficial effect on the reversal of metabolic abnormalities associated with obesity.

Antioxidant, Biochemical, and In-Life Effects of Punica granatum L. Natural Juice vs. Clarified Juice by Polyvinylidene Fluoride Membrane.

A clarification method was proposed to ameliorate the technological quality of fruit juices by preserving bioactive compounds. This study evaluated the in vitro antioxidant and hypoglycemic activities and the in vivo effects of Punica granatum L. natural (NJ) and clarified (CJ) juice by polyvinylidene fluoride (PVDF) hollow fiber membrane. CJ was more active as an antioxidant and as a α-glucosidase inhibitor than NJ. Mice were orally gavaged with water (Control), NJ, and CJ for 28 days. NJ group showed significant decrease of alanine aminotransferase, aspartate amino transferase, and creatine-phosphokinase. CJ administration was associated with urea, creatine-phosphokinase, and triglycerides values significantly lower with respect to the control. Oxidative status was ameliorated with CJ administration, showing a reactive oxygen metabolites (d-ROMs) reduction of 32% and a biological antioxidant potential (BAP) boosting of 23% compared to the control, whereas NJ did not show a similar effect. Results confirmed the beneficial properties of pomegranate juice, showing that membrane clarification may enhance such effects in terms of antioxidant activity.

Oxidative stability of a colombian criollo mango (Mangifera indica) drink fortified with peel / Estabilidad oxidativa de una bebida de mango criollo colombiano (Mangifera Indica) fortificada con cáscara

Background: the analysis of the oxidative stability allows to determine the functionality of the antioxidants present in food, over time. Objectives: in this research, a functional mango drink is elaborated and the changes in the antioxidant profile and physicochemical parameters of the drink subjected to accelerated storage conditions are evaluated. Methods: the drink was distributed at 22, 35 and 45°C for 80 days. To monitor oxidative stability, the antioxidant analyzes ABTS, ORAC, mangiferin, total phenols and total carotenoids were performed; in addition, physicochemical properties (pH and °Bx) and L*a*b*coordinates, were monitored. The fit of the data to the Arrhenius model was verified and the shelf life was determined considering a 50% loss in the evaluated attributes, such as the critical limit. Results: the deterioration of the antioxidant attributes and the color at the study temperatures is observed, being more pronounced at 45°C. The least stable attributes are the carotenoids and the b-coordinate, presenting losses greater than 50%. The values of mangiferin exhibit deterioration lower than 40% and similar in the temperatures evaluated. The pH and Brix degrees do not show significant changes. The deterioration reactions are of order one and followed the Arrhenius law, presenting coefficients of determination greater than 0.90. The values of the activation energy (Ea) are within the range reported for fruit juices, standing out the value found for the b* coordinate (44.59 kJ.mol-1). Conclusions: the ORAC units are the chosen attribute to condition the life of the beverage, giving 10 months of useful life at 4°C, however, it is recommended to perform sensory and microbiological analyzes under the same conditions.
