METHOD FOR RECOVERING PEPTIDES/AMINO ACIDS AND OIL/FAT FROM ONE OR MORE PROTEIN-CONTAINING RAW MATERIALS, PRODUCTS PRODUCED BY THE METHOD, AND USE OF THE PRODUCTS

摘要

According to a first aspect there is a method for producing a protein-freeproduct comprising free amino acids and short peptides, wherein raw proteinmaterials are crushed and hydrolysed with endogenous enzymes and passedthrough different separation processes, including coagulation of proteinresidues, in order to obtain the desired product. The invention furthercomprises the product obtained and uses thereof. According to a second aspect,a protein product enriched with free amino acids and short peptides isproduced, wherein the raw protein materials are ground and hydrolysed withendogenous enzymes, and wherein the hydrolysate undergoes various separationprocesses. The product obtained comprises proteins, short and long peptides,free amino acids and minerals and has a low fat content and salt content.According to a third aspect, hydrolysation of a protein-containing rawmaterial and separation of amino acids/peptides is carried out, wherein thehydrolysation is effected by using the endogenous enzymes of the protein-containing raw material. The hydrolysate is passed through a membrane filter,wherein peptide/amino acids follow a permeate stream, whilst the activeenzymes continuously break down any protein residues that are deposited on themembrane surface. The enzymes are passed together with retenate back to thehydrolysis. Furthermore, an amino acid and peptide product and an oil productare described and the use thereof is disclosed.
