Abstract
Based on the hypothesis of an additional electrostatic stabilization of the colloidal caseinate-calcium-phosphate complex of milk with a lack in the activity of calcium ions, the method of magnesium enrichment of milk proteins dur-ing their coagulation is proposed. The fact of the transition of magnesium ions added to the milk with a low concentra-tion of calcium ions into the milk clot during rennet coagulation is experimentally confirmed. The possibility of en-richment of milk clot with other metal ions, for example with iron, is considered.Keywords
