Description

Milk powder for improving children anorexia and preparation method thereof Technical Field The invention relates to the field of dairy product processing, in particular to milk powder for improving children anorexia and a preparation method thereof. Background The digestive system of children is not fully developed, which may lead to insufficient digestive functions, and although the current food is more and more abundant, many children still have anorexia. The children anorexia and weakness of spleen and stomach or lack of trace elements are related, and the children anorexia and weakness of spleen and stomach or lack of trace elements are mainly manifested in dyspepsia caused by lactose intolerance in milk products, and lactose cannot be digested and absorbed due to lactose deficiency or low activity of human intestinal mucosa, so that phenomena such as abdominal distension, diarrhea, vomiting and the like occur, and anorexia reaction can be generated for a long time. In childhood, the milk product is still the food with the best balanced nutrition, and the common solution is that the milk product can be relieved by methods such as probiotic treatment, lactase supplementation, traditional Chinese medicine conditioning and the like. However, the above method is cumbersome to implement, requires additional food sources for parents and children, and is relatively costly. The lactose-free formula can relieve the load of the digestive system and relieve the discomfort symptoms caused by lactose intolerance. However, the mode is single, and children with digestive system disorder or weakness of spleen and stomach are not obvious. The functions of spleen and stomach transportation and transformation are enhanced, the digestion and absorption capacity of the body to nutrient substances, particularly lactose, is improved, and the absorption and utilization of food are promoted, so that the energy and nutrition requirements of children for growth and development can be met. Aiming at the child anorexia, the invention further optimizes the components of the formula milk powder, and prepares the infant formula milk powder with high absorptivity and digestion promotion by optimizing the composition and the preparation process of the infant formula milk powder. The soybean flour contains soybean oligosaccharide, the soybean oligosaccharide has proliferation effect on probiotics such as bifidobacteria in intestinal tracts and has the effect of promoting digestion and relaxing bowel, and the soybean protein is a vegetable protein which can be equivalent to animal protein and is closest to human amino acid in structure, so the soybean protein is the most nutritious vegetable protein. Disclosure of Invention Aiming at the defects in the prior art, the application aims to provide the milk powder which is easy to absorb and promote digestion and can effectively improve children anorexia and the preparation method thereof. The invention adopts the following technical scheme: A milk powder for improving anorexia in children, comprising the steps of: S1, taking soybean low-temperature soybean meal as a raw material, putting the soybean low-temperature soybean meal into a tank, adding 9 times of water, stirring in the tank, and then sending the soybean meal into a high-speed separator to separate the soybean meal; S2, carrying out acid precipitation, separation, neutralization, sterilization and drying treatment on the protein water; S3, carrying out low-temperature superfine grinding on the dried protein powder by using a superfine grinder to obtain soybean protein micro powder with the particle size of more than 90% and less than 50 microns; S4, uniformly mixing whey protein powder, fresh cow milk, fructo-oligosaccharide, galacto-oligosaccharide, milk mineral salt, compound trace elements and compound vitamins to obtain mixed feed liquid; s5, homogenizing the obtained mixed feed liquid, homogenizing under high pressure, sterilizing, concentrating, and spray drying to obtain milk powder; S6, uniformly mixing the obtained milk powder, soybean protein micropowder, docosahexaenoic acid fish oil powder, arachidonic acid grease and composite probiotic powder to finally obtain infant formula milk powder; In the step S1, the stirring speed is 800-1000 rpm, and the stirring time is 60-120 min; In a further preferred embodiment, in the step S2, the neutralized alkali solution is preferably an alkali solution having a pH of 9.5 to 10.5. As a further preferred embodiment, the soybean protein micropowder, whey protein powder, fresh cow milk, fructo-oligosaccharide, galacto-oligosaccharide, milk mineral salt, compound trace elements, compound vitamins, docosahexaenoic acid and arachidonic acid in the above step S6 are added in a mass ratio of （50～70）：（30～40）：（180～200）：（4 .2～5）：（2～2.5）：（4 .2～5）：（0 .6～1 .2）：（0 .4～0 .5）：（0 .2～0 .8）：（0 .3～1 .0）,, which is too low in all the raw materials, and the efficacy of the formula is affected, while too
