Abstract

The invention relates to Alterac high-protein milk which is liquid dairy product with milk as raw material, with protein content no less than 3.5 percent and prepared by pasteurization, lactase degradation, killing enzyme, cooling and adding with Alpha-lactalbumin, lactoferrin and bovine colostrum powder containing immunoglobulin. The Alterac high-protein milk is characterized in that functional protein is added, so that the product not only is rich in nutrition, but also has the special functional and characteristic of improving immunity. Through the hydrolysis to partial lactose by lactase, the product not only has pleasing taste, but also largely solves the problems produced when lactose intolerant people drink the milk. The protein content is equal to or more than 3.5 percent, and can meet the dietary supplementation of 8g high-grade protein after being eaten 250ml every day. Sterilization is conducted through pasteurization (90 DEG C to 95 DEG C, and the temperature is kept for 15s), which furthest reduces the loss of nutrient in the milk.

Description

High-protein milk

Technical field

Related technical field is: the process technology of pasteurization milk and lactase hydrolyzes lactose technology.

Background technology

The pasteurization milk that existing market is sold is to be raw material with cow's milk or sheep breast, the fluid product of making through pasteurize.Its protein content is 〉=2.9%, and lactose content is 4.5% ~ 5.0%.Because its lactose content height is restricting the consumption of lactose intolerance crowd to milk.Its process chart is seen Figure of description.

Summary of the invention

" Australia is special blue " high-protein milk, be to be raw material, after pasteurize, through the lactase degradation treatment with the fresh milk, after the enzyme that the goes out cooling, add ALA, lactoferrin and contain the bovine colostrum of active immune globulin and the protein content made is not less than 3.5% liquid diary product.Be the low lactose high protein functional milk that adopts the pasteurize explained hereafter.Its process chart is seen Figure of description.

According to data, China has 70% lactose intolerance receptor approximately, and 70% population, immunity reduction excessive because of the quickening stress of work, rhythm of life arranged approximately, is in " inferior health " state.A kind of just novel dairy products that are fit to above-mentioned crowd demand of " Australia is special blue " high-protein milk.

Products characteristics is as follows:

Process characteristic: this product has increased the technology that lactase hydrolyzes lactose, cold addition method add the thermal sensitivity functional components based on the technology of general pasteurization milk;

Products characteristics:

A, this product make the lactase degradation rate reach 30%-40% by lactase hydrolyzable moiety lactose, not only make product have pleasant mouthfeel, have solved the problem that lactose intolerance milk drunk by people is produced simultaneously to a great extent.

B, colostrum have the adjusting body's immunity, strengthen the ability of body disease-resistant; ALA is a kind of crude whey albumen, is the fabulous source of essential amino acid and branched-chain amino acid; Be only can be in conjunction with the lactalbumin of calcium, its composition is near human milk, is difficult for irritated.Alpha lactalbumin contains abundant tryptophan, helps to alleviate stress and promotes sleep; Lactoferrin is a kind of multifunctional protein, regulates body's immunity, strengthens body resistance against diseases.This product has added ALA, lactoferrin and has contained the bovine colostrum of active immune globulin, makes this product not only have abundant nutrition, also gives it simultaneously and improves specific function characteristics such as immunity.

C, protein content 〉=3.5% are higher than 20% of GB 2.9%, take in every day under the prerequisite of 250ml, can satisfy the meal supplement of 8 gram high-quality proteins.

F, this product adopt the mode of pasteurize (90～95 ℃ are incubated 15 seconds) to carry out sterilization, have farthest reduced loss of nutritive components in the milk.

Description of drawings

Fig. 1 is the process chart of pasteurization milk.

Fig. 2 is the high-protein milk process chart.

The specific embodiment

1) raw material milk: raw material milk is surveyed physical and chemical index, enters sterilization process after qualified.

2) homogeneous: homogenizing temperature 60-65 ℃, pressure 18-20Mpa.

3) sterilization: 90 ℃, be incubated 15 seconds, after sterilization finishes, survey physical and chemical index, squeeze into aseptic jar after qualified.

4) lactase hydrolysis: 35 ℃, 1 hour and keep stirring.

5) enzyme that goes out: 75 ℃, 15 seconds.

6) cooling: be cooled to 4 ℃.

7) can: can is also printed the date of manufacture.

The major parameter of product inner quality standard/operative norm:

1. product inner quality standard:

Physics and chemistry: real milk solids 〉=13.90% fat content 4.00-4.10%
