Figure 4 shows a relationship between the DH and PR,for all studied conditions.An increase in PR was achieved by increasing the DH up to 25%.Above this value the PR stabilized,showing no further dissolution of the mussel meat protein,howover with a great cleavage of the soluble peptide bonds,as can be seen in eletrophoretic profile of the hydrolysate (figure 5).Hydrolysis process is characterized by high initial reaction rates ,in the beginning,when there are more active enzymes sites available for reaction and lower concentration of soluble in competition with the substrate,consequently a great amount of bonds are broken.This is followed by decreases in the reaction rate up to the stationary phase,where,apparently,hydrolysis no longer occurred.this profile could be associated to the presence of inhibition product by compounds formed during the hydrolysis and action of soluble peptides,which act as an effective substrate competitor for the
