Problems solved by technology

Although the protein content of this product is supplemented to more than 3.5%, the use of pasteurization will make its shelf life only 5-7 days, and the sales environment must be 2-6°C, which will greatly limit its sales channels and sales scope, and cannot achieve large-scale production. Area promotion

Abstract

The invention relates to high-protein low-fat milk and a production method thereof and belongs to the technical field of milk products. The high-protein low-fat milk and the production method thereof have the advantages that by formula and production method optimization, the protein content of the produced high-protein milk is increased from 2.3-3.5% to 6.0-8.0%, NRV% is increased from 4-6% to 10-13%, the milk is rich in nutrition, and a box of 250mL milk can provide 25-30% of required protein quantity for a consumer; high process adaptability is achieved, and milk material or water material can be satisfied; the production method is wide in raw material applicability and applicable to fresh milk, whole milk powder, skim milk powder or MPC whole-milk protein; meanwhile, the high-protein low-fat milk can adapt to UHT (137-140 DEG C, 3-30 seconds) sterilization and can be sold under normal temperature, the tetra pack sterilizing and filling technology allows the shelf life to reach six months, distribution channels and range are expanded, large-area popularization can be achieved, and more consumers can obtain high-quality enjoyment.

Description

technical field [0001] The invention belongs to the technical field of milk products, and relates to high-protein, low-fat milk and a preparation method thereof. Background technique [0002] At present, the protein content of room temperature milk products in the market is mainly between 2.3-3.0%, and a few high-protein milks such as: Mengniu Milk Deluxe, Yili Jindian, Sanyuan Ji, the protein content does not exceed 3.5%, and the NRV% is 3.5%-5 %, if the protein content exceeds 3.5%, the product is prone to protein aggregation, gelation, and water separation. [0003] The Chinese patent application with the application number CN200810100259 discloses a kind of high-protein milk. The key point is to use fresh milk as raw material, add α-lactalbumin, lactoferrin and bovine colostrum powder containing active immunoglobulin to make protein Liquid dairy products with a content of not less than 3.5% are sterilized by pasteurization (90-95°C, heat preservation for 15s). Although...
