METHOD OF RAW MILK PURIFICATION FROM LEAD Russian patent published in 2008 - IPC A23L1/15 

FIELD: technological process.

SUBSTANCE: method consists in introduction into raw milk, which is contaminated with lead in concentration of (1.1...4.0)±0.1 from maximum permissible concentration (MPC) of sorbent in the capacity of which the polyphepan is used in proportion from 0.3:1000. Purification is performed until concentration of 0.5 MPC and lower. Contact is performed at temperature of 6°C for 5 minutes with mixing. Then raw milk is purified from sorbent by centrifugal method in separator-milk-purifier for cold purification. Method allows to reduce the concentration of lead in raw milk down to (0.28-0.40)±0.1 MPC with degree of purification of (76-90)±1% accordingly.

EFFECT: reduction of lead concentration in raw milk.
