High-protein lactose-free milk and preparation method thereof

Abstract

The invention provides high-protein lactose-free milk and a preparation method thereof. The raw materials of the high-protein lactose-free milk are prepared from the following components in percentage by weight: 0.5-1% of milk protein concentration, 5.0-5.5% of desalted separated whey proteins, 2.5-3.5% of watery cream and the balance of water, totaling 100%, wherein the percentage by weight is that relative to the total mass of the raw materials. The preparation method comprises the following steps: (1) mixing the milk protein concentration, the desalted separated whey proteins and water, standing and filtering by virtue of a ceramic membrane to obtain slurry A; (2) carrying out pasteurization on the watery cream to obtain slurry B; (3) mixing the slurry A and the slurry B; (4) homogenizing; and (5) cooling and filling. According to the ceramic membrane filtration process, the problem that a high-protein product is easily coked on tubular or platy sterilization equipment is solved, and the final product helps solve the problem that the common milk drank by the diabetic patient is adverse to glucostasis and has the function of controlling blood glucose of the type 2 diabetic patient in an assistant manner.

Description

technical field

[0001] The invention relates to the field of food technology, in particular to high-protein lactose-free milk and a preparation method thereof. Background technique

[0002] With the improvement of living standards and changes in lifestyle, lack of exercise, overeating, and unreasonable intake of high-calorie, high-protein and low-fiber meals are common among citizens in our country. Coupled with the environmental pollution brought about by the increase in the degree of industrialization, the number of sub-healthy people has increased significantly, and various "lifestyle diseases" are also threatening human health. Diabetes is one of the representative lifelong diseases. According to the statistics of the World Health Organization, there are currently 300 million people suffering from diabetes (including recessive diabetes population) in the world, of which nearly 40 million are diabetic patients in my country, which is the second largest country in the worl...
