Abstract Jambolan (Syzygium cumini (L.) Skeels) is an under-explored fruit rich in polyphenols, which are associated with health benefits, such as increasing resistance to oxidative stress, inflammatory processes and cardiovascular, and platelet functions. These polyphenols can be obtained by extraction, but an efficient standard method remains a challenge. In this context, this work evaluated the impact of different pretreatments on jambolans to obtain bioactive compounds by aqueous extraction. An Air Circulation Oven (ACO) and Lyophilization (LYO) were used as pretreatments. In addition, the influence of mass, temperature, cycle, and time parameters were studied in the extraction methods used: Percolated Solid-Liquid (PSL), Conventional Solid-Liquid (CSL), and solid-liquid assisted by ultrasound (USL). The extraction yield was from 7.3% (ACO) to 46.3% (LYO), both using the PSL method. In addition, eleven phenolic compounds and six anthocyanins were detected by High Performance Liquid Chromatography-Diode Array Detector (HPLC-DAD), in expressive amounts of catechin and cyaniding in the LYO sample and, these extracts showed higher concentrations of bioactive compounds. The CSL method was more efficient on ACO samples and PSL on LYO samples. LYO extracts showed higher concentrations of bioactive compounds. Therefore, the use of a drying pretreatment results in extracts with a high antioxidant potential for application in the food, cosmetic, and pharmaceutical markets.

Abstract Rowe luwa is a traditional porridge from Southwest Sumba, Indonesia, made from the steamed pulp cassava leaves pounded together with rice. This study examined the effect of pre-gelatinization temperature on the physical quality and nutritional content of instant rowe luwa porridge. The experimental design used in this study was a Completely Randomized Design (CRD) with pre-gelatinization temperature factors, viz., 60 °C (X1), 65 °C (X2), 70 °C (X3), 75 °C (X4) and 80 °C (X5). Physical properties were measured by analyzing color, viscosity, rehydration, and syneresis, while for nutritional compositions, water content, ash, fat, protein, carbohydrate, and energy were evaluated. The simple linear regression was employed to examine the correlation between pre-gelatinization temperature and physical properties or nutritional composition. The results showed that the pre-gelatinization temperature correlated with physical properties, such as: viscosity (r = 0.9924), rehydration (r = 0.807) and syneresis (r = 0.841). Furthermore, the pre-gelatinized temperature significantly affected protein and carbohydrate contents (p < 0.05), while the moisture, ash, and fat contents showed negligible effect (p > 0.05). Principal Component Analysis (PCA) showed that instant rowe luwa porridge prepared with the pre-gelatinization temperature of 80 °C (object X5) had the highest viscosity, rehydration, syneresis, and protein contents compared to the other cooking temperatures. These preliminary data are useful for further research to determine the method and optimization formula of the instant rowe luwa porridge.

Abstract Preparing cooked food by sous vide is an alternative for the design of products that permit the consumer to eat quickly and practically, without losing the sensory and nutritional characteristics of foods. This study aimed to determine the sensory properties, the overall liking, and the consumer-consumption characteristics and predispositions regarding ready-to-eat high-nutritional-quality preparations made with locally produced vegetables and cooked by the sous vide technique. A vegetable millefeuille and a chicken and vegetable hamburger were prepared for sensory characterization. Questions related to the consumer's consumption characteristics and predisposition to purchase this type of product were incorporated into the survey. Consumers performed the sensory evaluation in their home, within the habitual living ambience where they consumed their usual diet. The results revealed that most consumers accepted both millefeuille (100 %) and chicken and vegetable hamburger (92 %) and also reported a predisposition for purchasing both preparations (87 % and 84 %, respectively). The main characteristics that made the consumption attractive were quality (95%), market availability (89 %), lack of practical cooking skills (87 %), the price (84 %), the shortness of time invested in preparation (78 %), and the consumer's occupation (73 %). These types of preparations constitute an innovative alternative for the design of products of higher nutritional quality, without ignoring the requirements for their consumption.

Resumo Com a mudança na alimentação dos adultos nas últimas décadas, aumenta o desenvolvimento de doenças crônicas não transmissíveis. Aumentar o consumo de alimentos funcionais, com ações metabólicas benéficas ao organismo, é uma estratégia para proporcionar benefícios à saúde em longo prazo. O objetivo deste trabalho foi identificar os fatores que têm influência na percepção e no consumo de alimentos funcionais por adultos. Neste estudo, dentre os fatores que interferem no consumo de alimentos funcionais identificados, os aspectos socioeconômicos, de saúde e de qualidade dos alimentos se destacaram. No âmbito geral, apesar de controvérsias, os estudos caracterizam os consumidores de alimentos funcionais como mulheres, de boa situação financeira e alto nível de escolaridade, que se preocupam com a saúde de forma global, na medida em que praticam atividades físicas e têm uma alimentação adequada. Ademais, percebe-se que a cultura local tem bastante influência na percepção dos alimentos funcionais. Alguns fatores, como a familiaridade, sejam do produto, seja da alegação funcional, também são importantes para determinar a atitude do consumidor perante esses alimentos. O sabor é o principal atributo sensorial que define o consumo de alimentos funcionais. Os consumidores também tendem a preferir alimentos que são considerados naturais e não processados. Portanto, estudos que relacionem hábitos globais de saúde e o consumo de alimentos funcionais podem ser interessantes para assim nortear as intervenções e a inovação na produção de alimentos nesta área.

Abstract The constant need for innovation in the food industries to meet the demands of consumers and the growing market for gluten-free and high-protein products have driven studies of mixed flour. In this study, 'BRS Platina' banana fruits were processed to obtain Whole Green Banana Flour (WGBF) and Green Banana Pulp Flour (GBPF) as well as leaves of Ora-pro-nóbis Flour (OPNF). Mixed flours were prepared by blending banana flours (WGBF or GBPF) with increasing levels of OPNF (from 5 to 25%). Flours were analyzed for physicochemical characteristics, mineral contents, Water Absorption Index (WAI), Water Solubility Index (WSI), and color. The main component of banana flours was starch, in which GBPF has the highest content. The WGBF had a higher mineral content, and in both flours, the potassium was at a greater level. OPNF showed the highest protein and mineral contents. Independent of the type of banana flour, mixed flours were darker, and had higher WAI and considerable increases in Mg, Fe, and Zn than no mixed ones. The blend of banana flours and Ora-pro-nóbis leaf flour can be a viable combination for preparing a variety of food products, due to its nutritional and technological properties.

Abstract Fermentation has the potential of converting fruit by-products into value-added products via an efficient, sustainable, and low-cost process. Traditionally, Mexicans use pineapple residues to produce a fermented beverage called tepache. As this soft drink is increasingly consumed in restaurants, it is necessary to develop an effective and reliable process to yield a final product with desirable physicochemical properties. In this work, tepache was prepared using an ultrasound pre-treatment to enhance the fermentation process and improve the end-product quality. The ultrasound was provided by a probe (25 kHz, 400 W) submerged in pineapple preparations before fermentation. Characterization of physicochemical properties was performed on samples processed under different types of amplitude (20 and 100%) and sonication time (5 and 10 min). In all samples, the pH, acidity, and ºBrix values were similar to those in commercial tepaches. On the other hand, microscopy revealed that 5 min of sonication induced positive changes in the suspended matter responsible for the physical stability of fruit beverages. The tepaches obtained with this method had color uniformity. Indeed, 5 min of sonication at the highest amplitude (16.34 kJ・cm-2) augmented the soluble solids during the initial phases of fermentation. Moreover, the results from IR spectroscopy proved that ultrasound helped the ethanol release from yeasts. The maximum ethanol yield, calculated by model fitting, had a positive variation of 35%. These findings prove that ultrasound is capable to induce physicochemical changes useful for the industrial production of tepache.

Resumo A utilização de matérias-primas funcionais vem crescendo nos últimos anos e tem como objetivo fornecer, além de nutrientes essenciais, compostos associados a efeitos benéficos à saúde. Dentre os ingredientes com alegações funcionais, a inulina tem sido considerada uma importante fibra alimentar. Além disso, o conhecimento e a utilização de Plantas Alimentícias Não Convencionais (PANCs) vêm recebendo destaque, valorizando a biodiversidade e a alimentação mais sustentável. Assim, o presente estudo teve como objetivo desenvolver sorvetes utilizando matérias-primas não convencionais, a planta ora-pro-nóbis e a inulina, a fim de produzir alimento funcional e inovador. Foram elaboradas duas formulações de sorvetes, que se diferenciaram apenas pela quantidade de inulina. Na Formulação 1 (F1), o sorvete de ora-pro-nóbis recebeu adição de 3% de inulina e, na Formulação 2 (F2), o sorvete de ora-pro-nóbis recebeu adição de 6% de inulina. Foram realizadas análises físico-químicas e de aminoácidos das folhas de ora-pro-nóbis. Posteriormente, foram conduzidas as análises microbiológicas, físico-químicas e sensoriais das formulações de sorvete. Os resultados foram comparados estatisticamente pelo método t-Student com nível de significância de (p˂0,05). O teor proteico das formulações foi elevado, 10,54 ± 2,20% para F1 e 12,13 ± 0,57% para F2. Não houve diferença significativa nos conteúdos de lipídios, cinzas, proteínas e fibra bruta entre as formulações. As amostras estão de acordo com os padrões microbiológicos estabelecidos pela legislação. Com relação à análise de incorporação de ar, a F2 apresentou valor superior (41,26 ± 0,13%) comparada à F1 (36,36 ± 0,17%). Além disso, a F2 apresentou menor taxa de derretimento (1,20 g/minuto) que a F1 (3,38 g/minuto). Os sorvetes apresentaram boa aceitação sensorial e podem servir como opção de consumo para as pessoas que procuram um produto saudável e com elevado teor de proteínas.

Abstract Pleurotus ostreatus (Jacq.) P. Kumm., the second most widely cultivated oyster mushroom was grown on paddy straw, which is cheap and readily available waste material. After harvesting and drying, nutritional, and antinutritional composition of P. ostreatus were estimated using the standard assay methods. Tannin and phytic acid were present in very negligible amount (0.095 ± 0.027 mg/g and 0.150 ± 0.083 mg/g, respectively), whereas oxalate and cyanide were absent in whole mushroom. In fact, P. ostreatus was hydrolysed with commercially available proteinase K, pepsin and trypsin with different concentrations of the enzymes (0.05%, 0.10% and 0.15%), at different temperatures (30 °C, 40 °C and 50 °C) for different time periods (60, 90 and 120 min) to get the mushroom protein hydrolysates. Degree of hydrolysis and protein content varied from 4.29 ± 1.12% to 99.42 ± 0.02% and from 0.25 ± 0.07 mg/mL to 3.22 ± 0.12 mg/mL, respectively. Maximum degree of hydrolysis and the highest protein content of protein hydrolysate was obtained when using 0.15% proteinase K, at 50 °C for 120 minutes. Mushroom protein hydrolysates thus obtained exhibited improved functional characteristics such as foaming capacity, foaming stability and emulsifying property than the unhydrolysed mushroom. Based on the result of the present study, the mushroom protein hydrolysates could be served as useful ingredient for food and nutraceutical applications.

Maximum degree of hydrolysis and the highest protein content of protein hydrolysate was obtained when using 0.15% proteinase K, at 50 °C for 120 minutes. Mushroom protein hydrolysates thus obtained exhibited improved functional characteristics such as foaming capacity, foaming stability and emulsifying property than the unhydrolysed mushroom. Based on the result of the present study, the mushroom protein hydrolysates could be served as useful ingredient for food and nutraceutical applications.","PeriodicalId":9112,"journal":{"name":"Brazilian Journal of Food Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67145122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract The study of controlled methods of cocoa fermentation on a small scale is important to assess the maintenance of heat generated in the last days of fermentation. The research aimed to study the impact of spontaneous fermentation in controlled fermentation systems on the quality and acceptability of fermented cocoa beans. A 2×3 complete factorial design used different controlled fermentation systems (jacket system, solar heater and wooden box) and pulp reduction as variables. Samples were analyzed for fermentation index and volatile aroma composition profile using Headspace-Solid Phase Microextraction (HS-SPME) and Gas Chromatography-Mass Spectrometry (GC-MS). The profile of volatile compounds is evaluated for the studied variables using a multivariate Principal Components Analysis (PCA). The results showed increasing fermentation times in the jacket system seeing that it raised the fermentation rate and accelerated it to five days of fermentation combined with pulp reduction. The PCA analysis showed differences in the chemical composition of volatile compounds that were mainly associated with the reduction of the pulping process than the type of controlled system in four days of fermentation.

Abstract The species Passiflora tripartita Kunth (tumbo) is endemic to South America, whose edible fruits are a rich source of antioxidant metabolites. This study aimed to develop a probiotic yogurt with tumbo fruit pulp, consisting of an adequate antioxidant capacity related to its content in phenolic compounds, flavonoids, and carotenoids, and with good acceptability. Antioxidant capacity was determined by radical scavenging capacity test (DPPH●) and cation radical scavenging capacity test (ABTS+●), total phenol content by Folin Ciocalteu method, total flavonoids, and carotenoids by spectrophotometric method, on days 1, 7, 14 and 21 of storage. The surface plate count method quantified Lactic Acid Bacteria (LAB). The results evidenced that at day 21 of the analysis, the antioxidant capacity presented high values (DPPH●: 8.774 mg GAE/g, 3.386 mg TAE/g, 6.159 mg AAE/g; ABTS+●: 11.630 mg GAE/g, 7.018 mg TAE/g, 9.218 mg AAE/g), the content of phenolic compounds presented high values (3746.389 mg TPGAE/g; 2355.933 mg TPTAE/g), as well as total flavonoids (52.421 mg Quercetin/g) and carotenoids (72.109 µg β-carotene/g). Yogurt presents a value of 3.4 x 108 CFU/g of LAB and it is therefore considered a probiotic. High values were determined as the sensory characteristics such as odor (6.89), color (6.97), texture (6.94), flavor (6.97), and acceptability (6.94), thus being analyzed according to the hedonic scale in 200 panelists. The physicochemical and microbiological quality of the yogurt complies with current regulations. In conclusion, the probiotic yogurt developed with tumbo fruit pulp had a high amount of LAB. It presented high antioxidant capacity correlated with its high content of phenolic compounds, flavonoids and carotenoids, which remained high during the 21 days of storage. Furthermore, it showed high acceptability and had adequate physicochemical and microbiological quality.
