process for converting whey in nutrients and feed especially for the rearing of calves

摘要

Proteins are isolated from whey and cereal products by first subjecting the mixture of the products mentioned to a starch hydrolysis, the whey serving as swelling agent and diluent during the hydrolysis. After separating off the unchanged protein as a first protein fraction, the low-molecular hydrolysis products resulting from the starch hydrolysis, preferably disaccharides and monosaccharides, are used to produce microorganisms. The single cell proteins produced in this manner are isolated as a second protein fraction. The two protein fractions can be used as food and feed additives.
