FIELD: food industry.
SUBSTANCE: invention relates to a method for purification of defatted milk contaminated with copper, lead and zinc in a concentration from 0.13, 0.23 and 0.34 of MAC respectively. According to the method, one introduces into defatted milk with residual fat content equal to 0.10-0.20% a sorbent preliminarily hydrated with distilled water which sorbent may be represented by alumina oxide powder, broken rice or licorice roots extraction residue, the weight ratio of milk to the sorbents being 25:1. Then one proceeds with maintenance during 20-30 minutes at a temperature of 50-55°C and the sorbent removal by centrifugal method in a milk purifier separator.
