Lactose-free infant formula food and preparation method thereof

Abstract

The invention provides a lactose-free infant formula food and a preparation method thereof. The preparation method disclosed by the invention comprises the following steps: adopting a dry-wet compounding process, namely producing vegetable fat powder by a wet process, and producing lactose-free whole milk powder by a lactose digestion process; performing dry mixing on the vegetable fat powder, thelactose-free whole milk powder, other main ingredients and auxiliary materials and bioactive substances, thereby obtaining the formula food suitable for lactose intolerant infants at an age of 0-12 months. According to the formula, the lactose is completely replaced with other carbohydrates, the lactose content of the product is less than 0.5wt%, and 1.8-2.2wt% of galactose having an important effect on brain development of the infants is remained. The protein in the formula is provided by lactoprotein, and the formula food is suitable to be eaten by the lactose intolerant infants so as to avoid lactose intolerance.

Description

technical field [0001] The invention belongs to the technical field of food for infants and young children, and in particular relates to a lactose-free formula food for infants and a preparation method thereof. Background technique [0002] The population of infants and young children aged 0 to 3 in my country is 70 million, and about 17 million newborn babies are born every year. The huge consumer groups have created a huge market space for infant milk powder in China. However, infants who mainly eat formula milk powder are lactose intolerant. Infected, seriously affected the normal growth and development of infants and young children. [0003] Lactose intolerance is due to the lack of congenital lactase or other pathological reasons, the activity of lactase is reduced, lactose cannot be decomposed into glucose and galactose, undigested lactose enters the colon with the digestive tract, and is fermented by bacteria to produce short Chain fatty acids such as acetic acid, pro...

AI Technical Summary

Problems solved by technology

[0007] At present, there is no formula for infants with lactose intolerance in China, and there are only a few imported lactose-free / low-lactose infant formulas on the market. As a result, the variety of lactose-free infant formula entering the Chinese market is scarce and restricted by sales channels. Many parents of babies with special medical conditions find it difficult to buy such products, and it is really hard to find a "fan"

[0008] Using the traditional preparation method, lactose is completely replaced by other carbohydrates (maltodextrin, solid corn syrup, etc.) in the formula, and the product hardly contains galactose, an important substance for the baby's brain development; The production of lactose-free infant formula requires a large investment on the one hand, and the establishment of a large-scale wet production line requires a lot of space, equipment, and personnel, and the investment is relatively large; etc.) are not suitable for the production of traditional spray-drying process, so breast milkization cannot be achieved
