Proteínas do feijão preto sem casca: digestibilidade em animais convencionais e isentos de germes (germ-free)

Abstract: O feijão (Phaseolus vulgaris, L. ) é uma leguminosa de grande importância para a dieta da população brasileira. No entanto, um de seus maiores problemas é representado pelo baixo valor nutricional de suas proteínas, decorrente, por um lado, da sua baixa digestibilidade e, de outro, do teor e biodisponibilidade reduzidos de aminoácidos sulfurados. Com o objetivo de avaliar a digestibilidade das proteínas albumina e globulina do feijão preto sem casca, foram realizados ensaios biológicos com camundongos isentos … Show more

“…But intestinal pH is lowered as the result of the organic acids produced during ITF fermentation in the intestinal mucosa. Consequently, the bile acids become less soluble and excreted with the feces, thereby reducing their intestinal absorption (Pereira & Costa, 2002 ). Secondly, as discussed previously, both acetate and propionate enter the liver through the portal vein.…”

“…However, like other legume plants, the pinto bean has anti-nutritional factors such as protease inhibitors (trypsin and chymotrypsin) and hemagglutinins that may reduce the digestibility of nutrients, affecting the animal performance when supplied raw (Alencar et al, 2014). Non-protein anti-nutritional factors (oxalates and phytates) may also be present in these legumes and compromise luminal absorption, given the possible presence of polyphenols and dietary fiber, which have the property of chelating calcium and other minerals (Pereira & Costa, 2002).…”
