Method for producing protein hydrolysates

摘要

The aim of the invention is to provide a method for producing protein hydrolysates that have defined molecular weight limits without carrying out enzymatic or pH-adjusting process steps. For this purpose, the method for producing protein hydrolysates from proteinaceous plant and animal materials is characterized by splitting the materials up in an aqueous medium under a targeted pressure build-up in a reaction chamber, the temperature and reaction being controlled by a characteristic curve of the system, and separating the suspension after splitting into a sediment containing the insoluble components of the starting material, and an aqueous supernatant in which the cleavage products of the materials are dissolved.

主权项

1. A method for manufacturing hydrolysates from wheat meal or animal meal, the method comprising:
processing the wheat meal or animal meal to a pourable suspension with water (mash) having concentrations of 5 to 40% meal, splitting of protein molecules within the mash by hydrolysis in an aqueous medium, wherein said step of splitting occurs in a reactor in a temperature range of 180° C. to 220° C., at a pressure of 50 bar to 75 bar, and within a reaction time of from 25 to 40 minutes, wherein said step of splitting occurs without a pH value adjusting step, separating the suspension having the split protein molecules into a sediment, which contains the insoluble constituents of the wheat meal or animal meal, and an aqueous supernatant, in which the split protein molecules of the wheat meal or animal meal are dissolved, and separating the split protein molecules from the aqueous supernatant, such that the split protein molecules have defined molecular weights of less than 20 kDa.
