摘要:
The present invention relates to compositions and methods for the production of a hydrolysate comprising at least one endoprotease and a tripeptidyl peptidase capable of cleaving tripeptides from the N-terminus a peptide and/or proteins having one or more of lysine, arginine or glycine in the P1 position wherein said tripeptidyl peptidase is capable of being used at a temperature between 45ºC and 70ºC.
摘要:
The present disclosure provides polypeptides having aminopeptidase activity and isolated nucleic acid sequences encoding the polypeptides. In some embodiments, the disclosure also provides to nucleic acid constructs, vectors, and host cells comprising the nucleic acid sequences as well as methods for producing the polypeptides. In some embodiments, the present disclosure further provides to methods of obtaining protein hydrolysates useful as flavor improving agents.
摘要:
The present disclosure provides compositions, methods, and uses concerning the preparation of a fermented milk product having a high protein content such as high protein yogurt, Greek yogurt, Labneh or sour cream comprising application of a microorganism and an exogenous protease to a milk substrate having a protein content of at least or greater than 6.5%. Application of proteases of the classes EC 3.4.21 (serine endopeptidases), EC 3.4.24 (metalloendopeptidases) and EC 3.4.17 (metallocarboxypeptidases) is envisaged. Especially application of neutrase (Protex 7L) and Protex 6L resulted in a decreased viscosity and a good flavour.

摘要:
The present invention relates to a method of preparing a fermented milk product. The method comprises the steps of treating a milk substrate with a low pH sensitive peptidase and a microorganism, and allowing the treated milk substrate to ferment to produce the fermented milk product.
摘要:
A method for the production of a hydrolysate comprising: (a) admixing at least one protein or a portion thereof with: (A) at least one endoprotease; and (B) (a') at least one proline tolerant tripeptidyl peptidase or fermentate comprising a proline tolerant tripeptidyl peptidase predominantly having exopeptidase activity wherein said proline tolerant tripeptidyl peptidase is capable of cleaving tri-peptides from the N-terminus of peptides having: Proline at P1; and synthetic amino acids at P1; or (b') at least one proline tolerant tripeptidyl peptidase having exopeptidase activity wherein said proline tolerant tripeptidyl peptidase is capable of cleaving tri-peptides from the N-terminus of peptides having: Proline at PV; and synthetic amino acids at PV; and (b) recovering the hydrolysate. The invention also relates to methods for producing a hydrolysate comprising the use of an endoprotease an exo-tripeptidyl peptidase of the S53 family and an aminopeptidase, to uses of a proline tolerant tripeptidyl peptidase, compositions, food and/or feed additive compositions comprising the same, as well as hydrolysates and uses of proline tolerant tripeptidyl peptidases.
