Using papain to hydrolyze the legumin and vicilin respectively showed that it could obtain higher DH from legumin than from vicilin, and the emulsifying activity of legumin hydrolysates was also increased more than vicilin hydrolysates. It was easier to hydrolyze the β-sheet fractions than α-helical fractions of broad bean legumin by papain, but to vicilin the β-sheet fractions was difficult to be hydrolyzed.
