the taste profiles
of the Alcalase-treated WGHs showed decreased bitterness (3.1→2.5) upon more extensive hydrolysis while umami (4.3→5.0) and overall acceptability (4.2→5.2) increased. On the other hand, the WGHs produced by Flavourzyme and Protamex exhibited increased bitterness from 2.4 to 3.0 and from 2.6 to 3.1, respectively, with increasing hydrolysis time. However, it seemed that taste profiles, such as umami, kokumi, and overall acceptability of the WGHs by Flavourzyme and Protamex were unaffected by hydrolysis time.
