METHOD OF PRODUCING SERUM WITH LOW PHOSPHORUS CONTENT Russian patent published in 2014 - IPC A23C21/00 A23J3/08 B01J41/00 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to food industry. The method includes nanofiltering liquid serum with pH 6-7 to obtain serum with low chlorine content, where the chlorine content is lowered to not more than 30 mmol per 100 g dry substances. The obtained serum passes through an anion-exchange resin in chloride form without passing through a cation-exchange resin. The milk serum has total calcium and magnesium content of at least 10 mmol per 100 g dry substances and phosphorus content of not more than 12 mmol per 100 g dry substances. Another version of the method includes passing liquid serum with low chlorine content of not more than 30 mmol per 100 g dry substances through an anion-exchange resin in chloride form without passing through a cation-exchange resin. The obtained milk serum and eluate which has passed the anion-exchange resin have pH 6-7. Total calcium and magnesium content is at least 10 mmol per 100 g dry substances in the milk serum and phosphorus content is not more than 12 mmol per 100 g dry substances. The milk serum with low phosphorus content is used to obtain a baby food mixture.

EFFECT: group of inventions is aimed at producing milk serum with low phosphorus and chlorine content and in which the initial calcium and magnesium content is preserved.
