A short analysis of the problem state and of the necessity of whey treatment (processing) is presented. Actuality and importance of the use of whey proteins as a part of baby food production formulas and various biologically active additives are noted. The methods of obtaining whey protein concentrate (WPC) including electrocontact one, being elaborated in the IAF ASM, are examined. The process main parameters (current density, voltage, temperature, the membrane type and state, liquid flow rate) and optimum conditions of protein recovery in WPC are investigated. It’s salt content quantity and quality analysis is presented. The role of calcium and phosphorus ions in the protein recovery process as well as their influence on WPC solubility is show
