Aiming to understand the impact of hardening on the biological potential of bean protein and peptides, we evaluated the antioxidant and vasorelaxant properties of common beans after and before hardening. It was also evaluated the effect of extrusion and autoclaving in the biological potential of hardened beans. In general, hardening caused a reduction from 13.5 to 39.6% on the antioxidant activity of the peptide-rich fractions. On the other hand, hardening did not strongly interfere with the vascular reactivity in thoracic aorta rings, being observed maximal relation varying from 801% to 84.7%. The thermal treatment caused a general increase in the antioxidant and vasorelaxant potential of these fractions, being observed EC50 values ranging from 0.22 mg mL... |

Significant initiatives exist within the global food market to search for new, alternative protein sources with better technological, functional, and nutritional properties. Lima bean (Phaseolus lunatus L.) protein isolate was hydrolyzed using a sequential pepsin-pancreatin enzymatic system. Hydrolysis was performed to produce limited (LH) and extensive hydrolysate (EH), each with different degrees of hydrolysis (DH). The effects of hydrolysis were evaluated in vitro in both hydrolysates based on structural, functional and bioactive properties. Structural properties analyzed by electrophoretic profile indicated that LH showed residual structures very similar to protein isolate (PI), although composed of mixtures of polypeptides that increased hydrophobic... |

O gênero Crotalaria possui, em geral, alcaloides de elevada toxicidade aos vertebrados. Crotalaria juncea é uma das espécies desta família e tem sido utilizada na adubação verde e no controle de pragas. Com isso, surge o interesse em identificar os principais metabólitos secundários presentes em extratos de sementes de C. juncea. Este trabalho utilizou cromatografia líquida de ultra alta eficiência acoplada a espectrometria de massas de alta resolução (UHPLC-ESI-qTOF-MS/MS) no modo positivo e negativo, identificando compostos ativos tais como flavonoides, derivados do ácido hidroxicinâmico e alcaloides. As informações obtidas auxiliarão na aplicação desta espécie vegetal na proposição de novos biocidas naturais. |
