Abstract
A method for converting blood, animal parts, bone waste, or meat scraps into useful products, which method comprises hydrolyzing such a substrate with a proteinase, preferably in the presence of urea, in an aqueous hydrolysis medium at a pH in a region in which the proteinase displays sufficient activity, subsequently inactivating the enzyme, and working up the hydrolyzate.
