Abstract: The present technology relates to a method for extracting enzymes from an enzyme-containing raw material, an enzyme composition obtainable by the method, and to the use of the enzyme composition for the hydrolysis of proteins or as a food supplement. Further, the present technology relates to a method for producing a protein hydrolysate from a protein-containing raw material.

Abstract: According to a first aspect there is a method for producing a protein-free product comprising free amino acids and short peptides, wherein raw protein materials are crushed and hydrolysed with endogenous enzymes and passed through different separation processes, including coagulation of protein residues, in order to obtain the desired product. The invention further comprises the product obtained and uses thereof. According to a second aspect, a protein product enriched with free amino acids and short peptides is produced, wherein the raw protein materials are ground and hydrolysed with endogenous enzymes, and wherein the hydrolysate undergoes various separation processes. The product obtained comprises proteins, short and long peptides, free amino acids and minerals and has a low fat content and salt content.
