Identification of potential inhibitory peptides of enzymes involved in the metabolic syndrome obtained by simulated gastrointestinal digestion of fermented bean ( Phaseolus vulgaris L.) seeds

The aim of this study was to determine the conditions of bean fermentation carried out by Lactobacillus plantarum to obtain biologically active peptide fractions after in vitro digestion. The results suggest that optimum process conditions should be selected according to the specific activity of peptides. Only a fraction with a molecular mass of 3.5–7 kDa obtained after fermentation at 22 °C for 3 h had α-amylase inhibitory activity. The optimal...
