ABSTRACT
Bioactive peptides can be obtained by in vitro hydrolysis of protein substrate using appropriate enzymes or by proteolysis from fermentation by specific bacteria. For example, a number of peptides produced by the enzymatic hydrolysis of caseins and whey proteins have been shown to have various biological activities with high potential for nutraceutical applications. Several review papers report on the biologically active sequences found in dairy proteins (1-5). Bioactive peptides are also found in fermented milk produced with lactic acid bacteria (6,7) or in fermented whey prepared with different bacteria (8).
