FIELD: food industry.

SUBSTANCE: inventions group relates to food industry. Milk raw materials lactose is hydrolysed. One performs the first nanofiltration of hydrolysed milk raw materials for separation of protein into the first nanofiltration retentate and sugars and mineral substances- into the first nanolfiltration permeate. One performs the second nanofiltration of the first nanofiltration permeate for separation of sugars into the second nanofiltration retentate and mineral substances - into the second nanofiltration permeate. The low-lactose or lactose-free milk product manufacture method involves manufacture of a lactose-free or low-lactose milk product with the desirable composition; such product contains the first nanofiltration retentate and the second nanofiltration permeate produced by the proposed method. The product can by concentrated till formation of a concentrate or powder.

EFFECT: inventions group ensures an efficient method for separation of proteins, sugars and mineral substances contained in milk without calcium and protein losses.
