Abstract
Analysis of the properties of protein fractions of milk whey is presented. The necessity of their re- ceiving is outlined, possible mechanisms of complexing and coagulation at electrophysical processing of secondary raw milk products are explained. Possible ways of optimization of protein fractions conversion into protein-mineral concentrate as well as fractional analysis of mineral receiving are described and their role in concentrate complexing is estimated. Electrophysical parameters at conditions of optimization, different compositions of anode liquid and types of separating elements are analyzed. Directions for future investigations aiming at the obtaining of high quality products at development of non-waste electrotechnolo- gies of milk whey processing are identified.
