Abstract

The present application relates to a method for preparing a dairy product based on the principle of forward osmosis, the concentrated dairy product prepared by the above method, and a continuous forward osmosis membrane system. Multiple concentration of the target solution is achieved by controlling the osmotic pressure difference between the solutions on both sides of the forward osmosis membrane, no heat source or strong external pressure is introduced, and the main nutrient content and nutrient ratio of the target solution are maintained. Compared with a reverse osmosis membrane concentration and a freeze concentration, the forward osmosis membrane concentration can greatly increase the concentration multiple of the dairy product, reduce the unit energy consumption, save the running cost. The scaled treatment of dairy product concentration is realized, and the microbial indicators, physical and chemical indicators and nutritional indicators of concentrated dairy products can meet the requirements of relevant standards.
