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.
