The silver nanoparticles (AgNPs) green synthesis has been investigated by selecting naturally occurred reduction and stabilizing/capping agents. In this work, Ilex paraguariensis aqueous extract in the one-step biosynthesis of AgNPs is reported. The synthesis was carried out at room temperature under different pH (5.0, 6.8 and 8.5) and extract conc...

Alimentos tipo snacks obtidos por extrusão podem ser adicionados de subprodutos agroindustriais, alternativa de baixo custo para incrementar o valor nutricional, e Spirulina platensis (SP) fonte de proteínas e antioxidantes. Neste estudo foram desenvolvidos snacks, usando delineamento experimental 2² onde se testou as variáveis SP (S. platensis) -...

Em face da crescente incidência de diabetes se faz necessário desenvolver alimentos práticos que contenham menos carboidratos disponíveis e/ou nutrientes que apresentem efeito positivo sobre a glicemia pós prandial. O objetivo deste trabalho foi avaliar a viabilidade do bagaço de malte (BSG) em diferentes proporções e granulometrias, e a adição de...

Extruded breakfast cereals they have low nutritional and high energetic values. The aim of this study was to develop extruded breakfast cereals by replacing part of corn meal by different proportions of by-products of grape (5-10%) and peach palm (7.5-15%). Samples were sweetened with xylitol while moisture was controlled with grape juice. Six form...

The use of green synthesis to obtain silver nanoparticles is an efficient method and often studied by not using reagents and solvents that may cause toxicity both in product as residual synthesis process, thereby extending its application. In this work was used for the first time as a reduction of silver ion, aqueous extract of yerba mate (Ilex par...
