Abstract BACKGROUND Yerba mate extract was encapsulated in electrospun zein fibers. Solutions were prepared with 30% (w/v) zein, and yerba added at concentrations of 1%, 3%, 5% (w/w). The rheology electrical conductivity the polymer solutions evaluated. fibers characterized through an analysis total individual phenolic compounds, antioxidant activity, Fourier‐transform infrared (FTIR) spectra. Morphology, size distribution, thermal stability also release kinetics loaded different evaluated a...

This study aimed to evaluate the influence of transglutaminase addition on technological properties and in vitro starch digestibility gluten-free cakes brown, black, red rice, as well effect baking content phenolic compounds. Transglutaminase exerted significant only brown rice cake, resulting a decrease crumb firmness an increase specific volume. Red treated with presented lower glucose release rate (k) compared without enzyme. Cakes from pigmented varieties had k values than cakes. Baking...

Abstract BACKGROUND Plants activate defense mechanisms to cope with adverse environmental conditions, leading the accumulation and / or depletion of general specialized metabolites. In this study, a multiplatform untargeted metabolomics strategy was employed evaluate metabolic changes in strawberry fruit cv. Camarosa grown under osmotic stress conditions. Liquid chromatography‐mass spectrometry (LC‐MS/MS) gas (GC‐MS) data from strawberries two water‐deficit irrigated at 95% crop...

Abstract This study evaluated the influence of different fluidized‐bed drying temperatures (20, 60, and 100 °C) on cooking properties, in vitro starch digestibility, phenolic bioaccessibility black rice. The results indicated that formation fissures grains dried at or above 60 °C reduced physical integrity after cooking, increasing digestion rehydration ratio, time, hardness adhesiveness. Due to higher digestibility temperatures, an increase ferulic acid, which was previously associated with...

This report aims to characterize the bioactive content of pepper ( Capsicum L., Solanaceae) accessions from a Brazilian germplasm collection. Peppers are currently major vegetable crop worldwide, with 31 Tg produced in 2013, according FAO. Seventy‐two annuum C. baccatum chinense Jacq., and frutescens L. were evaluated high variability was observed soluble solids, pH, acidity, fruit color, total phenolic content, carotenoid antioxidant potential, capsaicinoid content. Accessions P119, P302,...

A simple method for treating fresh and processed meat with tetramethylammonium hydroxide (TMAH) is proposed the determination of Ca, Fe Mg by flame atomic absorption spectrometry (FAAS) Cu graphite furnace (GFAAS). The accuracy was evaluated comparison results using two other sample preparation procedures analysis certified reference materials. No significant differences between were found at 95% confidence level. Limits detection Cu, 45.0, 0.2, 16.0 0.3 µg g-1, respectively. High-resolution...

In this work, the suitability of a new polymer family has been investigated as capillary coatings for analysis peptides and basic proteins by CE. This designed to minimize or completely prevent protein-capillary wall interactions modify EOF. These coating materials are linear polymeric chains bearing side cationizable moiety dentronic triamine derived from N,N,N',N'-tetraethyldiethylenetriamine (TEDETA), which is linked backbone through spacer (unit labeled TEDETAMA). Four different polymers...

Abstract Background and objectives Many breweries have attempted to widen their offers by developing innovative products that meets consumer demands. Brown‐, red‐, black‐pericarp rice were malted used for brewing. The color, the physicochemical properties, γ‐aminobutyric acid (GABA), phenolics profile, free radical scavenging capacity of raw rice, malt, obtained beers evaluated. Findings beer made from black malt showed 18 times more nitrogen content when compared brown beer. Regarding GABA...

Two different sample preparation methods were evaluated for meat samples employing the solubilization in alkaline or acidic media. The aim of this study was to determine Na and K levels after with tetramethylammonium hydroxide (TMAH) at room temperature, formic acid heating a digester block 50 ºC ca. 2 h. showed be simple robust method better alternative relation mineralization conventional procedures, allowing complete even when small quantities TMAH used. validated by using certified...

Os tegumentos desempenham importante função de proteção às sementes, e podem apresentar características diferenciais entre os genótipos soja. O objetivo do trabalho foi determinar a composição química analisar estrutura interna dos soja com cores contrastantes, assim como avaliar absorção água destas sementes. Foram testados quatro sendo dois tegumento preto (linhagens IAC TP) amarelo (cultivares BMX Potência RR CD 202). Inicialmente, as sementes foram multiplicadas, na safra 2012/2013, em...

As pequenas frutas, como o mirtilo (Vaccinium spp.), apresentam propriedades nutricionais e alto potencial antioxidante. Práticas de manejo a época poda podem provocar diferentes respostas nas plantas, devido alterações condições climáticas que as plantas estarão expostas durante seu período reprodutivo. O objetivo do presente trabalho foi avaliar efeito da seca sobre produção atributos qualidade dos frutos mirtileiro, cultivares Clímax, Bluegem Powderblue, mesorregião Pelotas, RS. Foram...

Due to the high prevalence and clinical relevance, scorpionism is a critical public health issue in several Brazilian regions. Tityus serrulatus, commonly known as yellow scorpion, most venomous genus found fauna associated with severe manifestations such localized pain, hypertension, sweating, tachycardia complex hyperinflammatory responses. In general, T. serrulatus venom contains mixture of active compounds, including proteins, peptides, amino acids. Although knowledge protein fractions...

O mirtileiro possui frutos com alto potencial antioxidante e nutracêutico. Este pode ser influenciado pela severidade da poda nas plantas, principalmente em função do impacto na produção dos efeitos aumento radiação solar incidente sobre os frutos. objetivo presente trabalho foi avaliar o efeito intensidade seca a atributos de qualidade das cultivares Clímax, Bluegem Powderblue, produzidas mesorregiäo Pelotas-RS.
