Abstract

The invention relates to a method and device for changing the functional features, with no alteration thereof, of a protein preparation, preferably isolates or concentrates from plant seed-based proteins. The inventive method consists in heating a proteinic preparation for producing perishable or dry products as a starting material or component for protein-containing foodstuff. According to the invention, the proteinic preparation is exposed to a high frequency electromagnetic field, so that, due to evenly distributed temperature, the total volume of the proteinic preparation is heated.
