Problems solved by technology

However, the existing technology usually decomposes lactose into monosaccharides, namely galactose and glucose, through enzymatic hydrolysis technology. Although it can solve the problem of lactose intolerance, it still contains monosaccharide sugar, which still cannot meet the requirements of diabetic patients.
[0004] No report on lactose-free milk with lipid-lowering function has been found so far

Embodiment 1

[0034] This embodiment is a production process for preparing skimmed lactose-free milk, including the following steps:

[0035] Step 1: Preheat the raw milk to 40°C;

[0036] The second step is to remove impurities through clean milk;

[0037] The third step is to separate skimmed milk and fat by a centrifuge; the lactose content in the separated fat is ≤0.1%, and the fat content in the skim milk is ≤0.1%;

[0038] The fourth step is to adjust the pH of the casein in the skimmed milk to 4.5~5.0 with 3% hydrochloric acid, and flocculate by the isoelectric point method;

[0039] The fifth step is to concentrate the casein through membrane filtration and pass through the lactose-containing filtrate. The membrane adopts a tubular membrane with a pore size of 0.8 ~ 1.2 μm and a membrane pressure of 0.3 Mpa, and the concentration ratio is 8-10 times; then the casein is rinsed;

[0040] Step 6, homogenize the casein;

[0041] Step 7: Membrane filtration and sterilization, the membrane adopts a t...

Embodiment 2

[0044] This example is a production process for preparing skimmed lactose-free milk. It first produces lactose-free milk powder (steps 1-8), then produces biologically active water (steps 9-11), and finally mixes the two to obtain lactose-free milk (steps 1-8). 12 steps), including the following steps:

[0045] Step 1: Preheat the raw milk to 40°C;

[0046] The second step is to remove impurities through clean milk;

[0047] The third step is to separate skimmed milk and fat by a centrifuge; the lactose content in the separated fat is ≤0.1%, and the fat content in the skim milk is ≤0.1%;

[0048] The fourth step is to adjust the pH of the casein in the skimmed milk to 4.5~5.0 with 3% hydrochloric acid, and flocculate by the isoelectric point method;

[0049] The fifth step is to concentrate the casein through membrane filtration and pass through the lactose-containing filtrate. The membrane adopts a tubular membrane with a pore size of 0.8~1.2μm and a membrane pressure of 0.3~0.5Mpa, a...

Embodiment 3

[0059] After mixing 50 parts by weight of hawthorn and 30 parts by weight of cassia seeds, they were mixed with the lactose-free milk obtained in Example 2 at a total ratio of 7:93, and homogenized and sterilized to obtain lactose-free reduced-fat milk.

Abstract

The invention provides lactose-free lipid-lowering milk and a production method thereof. The lactose-free lipid-lowering milk is prepared from a main material and auxiliary materials in the weight ratio being (90-98):(2-10), wherein the main material is lactose-free milk, the auxiliary materials comprise 50-80 parts by weight of hawthorn fruit powder, 10-30 parts by weight of cassia seed powder, 10-20 parts by weight of black fungus polysaccharides and 0.1-1 part by weight of phytosterol. During preparation, firstly, components of the auxiliary materials are mixed in proportion and then mixed with the lactose-free milk, the mixture is homogenized and sterilized, and the lactose-free lipid-lowering milk is obtained. According to the lactose-free lipid-lowering milk, various Chinese herbal medicine components perform a synergistic function and have a remarkable curative effect on hyperlipidemia; the content of lactose in the lactose-free milk is lower than 0.1%, and the lactose-free lipid-lowering milk is suitable for lactose-intolerant people; due to complete removal of lactose and monosaccharide, the lactose-free lipid-lowering milk is also suitable for people who have higher requirements for the content of sugar, such as people suffering from diabetes.

Description

Technical field [0001] The invention relates to the technical field of dairy products, in particular to a lactose-free low-fat milk and a production method thereof. Background technique [0002] Hyperlipidemia refers to a disorder in which one or several lipids in the blood are abnormally elevated, and is a common disease of middle-aged and elderly people. Due to the improvement of living standards, the number of young people has gradually increased in recent years. Hyperlipidemia is one of the important causes of cardiovascular diseases such as cerebrovascular disease and coronary heart disease. And it is closely related to diabetes, kidney disease and fatty liver. According to the autopsy results, the incidence of coronary artery and aortic atherosclerosis was 58.36% and 88.31% in people aged 40-49 years. Therefore, reducing blood fat is of great significance to the health of high-fat people. Hyperlipidemia not only brings great pain to patients mentally and physically, but ...
