Problems solved by technology

[0007] In the traditional production process of adding enzyme preparations before sterilization, the hydrolysis process is carried out on the production line of the product, and a hydrolysis system is needed to support the production of the product, so the investment in factory equipment is also relatively high
Moreover, since it takes a period of time to fully hydrolyze, the subsequent processing technology has to wait for a period of time to continue, so the traditional production of the product is not continuous but intermittent production, which increases the equipment investment of the factory. , the utilization rate is greatly reduced

Abstract

The invention relates to a low-lactose milk preparation method which comprises the following steps: (1) mechanical impurities of raw milk are removed by milk purification technique; (2) raw milk after purification is sterilized at ultra-temperature or pasteurized and then cooled to temperature below 8 DEG C; (3) milk compound is prepared; (4) the prepared milk compound is sterilized at ultra-temperature or pasteurized and cooled; (5) lactase preparation is added under aseptic condition; (6) the milk is bottled sterilely. The milk compound in step (3) also comprises: 0.1-10 wt parts of dietary fiber for increasing the health care function of the milk and further comprises essence less than 2 parts by wt. The method of the invention overcomes the shortcoming of low lactose hydrolysis rate of the prior technique. The product prepared by the method of the invention has good stability, and is particularly suitable for people with severe lactose intolerance symptom. The invention is also added with dietary fiber in the formula.

Description

technical field [0001] The invention relates to a method for producing functional milk, in particular to a method for preparing low-lactose milk. Background technique [0002] Lactose is a special sugar in animal milk, the content in milk is about 3.6% to 5.5%, almost all in solution state. Lactose is a disaccharide. One molecule of lactose is decomposed by lactase into one molecule of glucose and one molecule of galactose. Glucose can supply energy to the human body, while galactose can promote the production of cerebrosides and polysaccharides. Intellectual development plays an important role. [0003] Although milk is rich in nutrition, some people will experience symptoms such as abdominal distension, abdominal pain, vomiting and diarrhea after drinking milk, which is called "lactose intolerance" in medicine. This is because these people lack enough lactase that can decompose lactose in milk. Only after lactose is decomposed can the monosaccharides enter the blood thro...
