The hydrolysis curves of TRMHs, illustrated in Fig. 1, show a rapid
hydrolysis for the first hour, indicating that a large number of peptide
bonds were cleaved. At the same level of enzyme, Alcalase showed a
higher hydrolytic activity (DH=22%) followed by enzyme preparation
from B. subtilis A26 (DH = 18%), crude proteases of R. clavata (DH =
15%) and then Neutrase (DH=11%). Neutrase was reported to produce
food hydrolysates with a low degree of hydrolysis [29]. The differences
in DH values are
