Problems solved by technology

[0003] At present, concentrated milk protein powder mainly relies on imports in the domestic market, and there are problems such as unstable supply, long supply cycle, and large price fluctuations. At the same time, the domestic demand for MPC is increasing day by day, and its research is only at the experimental level. Therefore, there is an urgent need for relevant research and practice in industrial production

Abstract

The invention relates to the field of deep processing of dairy products, in particular to milk protein concentrate (MPC) produced by a membrane treatment technology, and a preparation method of the milk protein concentrate. The preparation method comprises the following processes of inspecting raw milk, preheating the inspected raw milk, and performing centrifugal sterilization and centrifugal separation so as to obtain skim milk; then performing pasteurization on the skim milk, then transporting the skim milk after being subjected to pasteurization to ultra filtration membrane equipment, setting concentration factors and the temperature of a control system, and enabling the skim milk to construct solid matters in the ultra filtration membrane equipment so as to obtain trapped fluid; performing concentration on the trapped fluid so as to obtain concentration fluid; preheating the concentration fluid, and then sequentially drying the preheated concentration fluid through a spray drying tower and a fluid bed so as to obtain the milk protein concentrate; and packing the milk protein concentrate, and performing metal detection. Through the adoption of the milk protein concentrate disclosed by the invention, milk protein having high-quality high protein content can be obtained, besides, a part of fat, a part of lactose and a part of mineral substances are reduced, the added value of products is higher, and the milk protein concentration is a new protein source.

Description

technical field [0001] The invention relates to the field of deep processing of dairy products, in particular to a concentrated milk protein powder produced by a membrane treatment process and a preparation method thereof. Background technique [0002] Concentrated milk protein powder (MPC) refers to raw milk (with or without adding other dairy raw materials) as raw material, after milk cleaning, pasteurization, skimming (or non-skimming), ultrafiltration and concentration, etc., to remove part of the water, After fat, lactose and minerals, the dairy products processed by drying and spraying are widely used in yogurt, milk drinks, neutral milk, baked goods, meat products, sports nutrition food and other products . [0003] At present, concentrated milk protein powder mainly relies on imports in the domestic market, and there are problems such as unstable supply, long supply cycle, and large price fluctuations. At the same time, the domestic demand for MPC is increasing day ...
