Estimating the term…
A method of enzymatically producing a protein hydrolysate from a protein substrate is described, wherein a proline-specific endoprotease or a composition containing a proline-specific endoprotease and optionally a subtilisin or a metallo endoprotease, and other enzymes such as carboxypeptidases, is used to produce a protein hydrolysate enriched in peptide fragments having a carboxy terminal proline residue. Such protein hydrolysates may be used as such or to reduce bitterness in foods nutritionally supplemented by protein hydrolysates, as well as to produce hydrolysate containing foodstuffs having low antigenicity.
A protein hydrolysate which comprises peptides, wherein the molar fraction of peptides carrying a carboxy terminal proline is more than two times the molar fraction of proline in a protein substrate used to generate the protein hydrolysate, and wherein the protein substrate is selected from the group consisting of whey, casein and soy.
A protein hydrolysate comprising peptides selected from the group consisting of
A method of enzymatically producing a protein hydrolysate from a protein substrate, which method comprises incubating the protein substrate with sufficient proline-specific endoprotease to produce a protein hydrolysate which comprises peptides, wherein the molar fraction of peptides carrying a carboxy terminal proline is more than two times the molar fraction of proline in the protein substrate used to generate the protein hydrolysate, and wherein the protein substrate is selected from the group consisting of whey, casein and soy.
