nevertheless,hydrolysates prepared using bromelain and Protamex were found to be more bitter than that with Flavourzyme,unlike the similar bitter taste between B4⁄and F4⁄ observed in this study. The taste of the hydrolysates was strongly influenced by the choice of proteases but the type of substrate also made a large contribution to the composition of peptides and amino acids after hydrolysis, consequently the taste of the end products.
