Development of the technology of milk without lactose by diafiltration method

Experiments with application of membrane methods have been carried out in the frames of development of the technology of milk production and the products on its base. The way of diafiltration on ceramics ultrafiltration membranes made in Russia and in other countries has been offered. It is possible to reduce lactose content to the level not more than 0,01g/l in skim milk at 5-6 times diafiltration. Efficiency of lactose content reduction in the milk with 2,5 and 3,2 % fat has been also demonstrated.
