Proteolytic enzymes, activities commercially available

In addition to studies on enzymic solubilization of solvent-extracted FPC, the relative effectiveness of more than 20 commercially available proteolytic enzymes in the production of hydrolysates from a specially prepared haddock protein substrate has been determined (13). The concentration of enzyme, at its optimum temperature and pH, required to effect a 60% digestion in a 24-hr period was the inverse measure of enzyme activity. Pronase exhibited the greatest activity per unit weight. In general the microbial proteases ranked low in relative activity. Porcine pepsin, papain, and pancreatin combined good activity with moderate cost.
