The present invention provides proline specific endopeptidases. The present invention further provides methods for use of proline specific endopeptidases for use in reduction of chill haze in a beverage, including beer. The present invention further provides methods for producing protein hydrolysates using proline specific endopeptidases. Also provided are methods of treating disease, including Celiac disease using proline specific endopeptidases. Also provided are nucleic acids encoding the proline specific endopeptidases and host cells for production of the proline specific endopeptidases.

Disclosed is a simplified method for producing a protein hydrolysate, the method having the advantages of decreasing costs associated with energy, materials, and space as compared to that of conventional methods. A protein hydrolysate/enzyme composition is also disclosed.
