Technical Field
The invention belongs to the field of dairy processing, and relates to preparation of children milk powder, in particular to children formula milk powder for improving immunity and constipation and a preparation method thereof.
Background
Parents are concerned about diseases of their children, and the "improvement of immunity" becomes one of the most concerned topics of parents today. At present, the methods adopted by parents to enhance immunity mainly comprise three main types, one type is infant tuina, and the methods are easy to cause crying and screaming of children to be mismatched, so that the tuina cannot be carried out; one is a medicine for improving immunity, and the medicine for improving immunity after being taken for a long time can bring side effects to children; the other type is food therapy, and the food therapy method is optimal for eating the children formula milk powder, so that the children formula milk powder is beneficial to enhancing the immunity of children while meeting the nutrient substances required by the growth and development of the children.
However, the constipation of children is easy to appear if children drink the formula milk powder for a long time and drink the formula milk powder unreasonably. Constipation is one of the common digestive tract problems of children, and is often manifested as decreased defecation frequency, difficulty in defecation, dry stool, pain in the defecation process and the like, and seriously affects the health and life quality of children. The constipation of children is mainly caused by unreasonable dietary structure, small intake of dietary fiber and slow gastrointestinal motility, and the occurrence of constipation aggravates the unreasonable dietary structure of children to cause vicious circle. Improper long-term dietary structure of children can lead to malnutrition of children, and further reduce the immunity of children. Therefore, the development of a children formula milk powder for improving constipation and immunity of children is an urgent problem to be solved at present.

the animal bifidobacterium can promote mucosal tissues to synthesize IgA, and improve the infection resisting capacity of organisms, so that diarrhea, allergy and virus infection are effectively prevented, and the immunity of human bodies is improved. Meanwhile, the animal bifidobacterium can soften the stool and reduce the occurrence of constipation; the invention effectively increases the number of active probiotics in the intestinal tract by increasing animal bifidobacteria and lactobacillus bifidobacteria;
lactoferrin promotes the maturation and activation of immune cells by controlling the secretion of proinflammatory factors, N-acetylneuraminic acid can improve the absorption capacity of intestinal tracts besides forming competitive combination with toxins, pathogenic bacteria and virus particles, and the anti-virus and absorption capacities of the intestinal tracts of children are greatly improved under the combined action of the N-acetylneuraminic acid and the toxins, the pathogenic bacteria and the virus particles, so that the immunity is improved;
according to the invention, a plurality of dietary fibers, OPO and two probiotics are added, so that the constipation can be improved by softening excrement and promoting intestinal peristalsis and proliferation of the probiotics in the intestinal tract, and the immunity can be improved by the proliferation of the probiotics and the product of immune substances and lactoferrin and N-acetylneuraminic acid;
after the children formula milk powder for improving immunity and constipation is drunk, the total effective rate for improving constipation after 7 days is more than 81.25%, and the total effective rate for improving constipation after 14 days is more than 87.5%, so that the children formula milk powder has the function of obviously improving constipation;
DHA algae oil powder, arachidonic acid powder and phosphatidylserine are also added into the milk powder, so that the intelligence and memory of children can be effectively improved;
according to the milk powder, lactose is adopted to replace sugar substances such as white granulated sugar, fructose, maltodextrin, solid glucose syrup and the like, edible essence is not added, the obtained children formula milk powder capable of improving immunity and constipation is purer, and blood sugar metabolism is not influenced after the milk powder is eaten;
the milk powder takes fresh milk as a main material, is controlled within 2 hours from the milking to the processing, retains the nutritional ingredients and active substances in the milk to the maximum extent, and is more fresh; the production process is simple and suitable for large-scale industrial production; the active substance is added by a dry method, so that the activity of the active substance can be maintained to the maximum extent.
The children formula milk powder capable of improving immunity and relieving constipation is suitable for children, and is particularly suitable for children prone to constipation.

Example 7 evaluation of Constipation preventing Effect of Children formula milk powder for improving Immunity and improving Constipation
In this example, trial drinking tests were performed on the children formula milk powders M1-M6 and the commercially available children formula milk powders for improving immunity and relieving constipation prepared in examples 1-6, respectively.
The trial drinking test disclosed that a total of 112 children of 6 years old with constipation symptoms were recruited, wherein the height of the boys was 118 + -0.5 cm and the weight was 21 + -0.5 kg, and the height of the girls was 117 + -0.5 cm and the weight was 20.5 + -0.5 kg, for half of the boys and the girls. The test drink was recorded as a questionnaire from 7 days before the drink to 14 days after the drink.
126 children of 6 years old who participated in the trial were randomly divided into 7 groups, each of which was male and female. Wherein, the I to VI groups respectively drink the children formula milk powder for improving immunity and improving constipation prepared in the examples 1 to 6 in a trial way, and the control group drinks the children formula milk powder sold in the market in a trial way. The drinking method is as follows: the children formula milk powder is prepared by adding 180mL of warm water into 26g of the children formula milk powder each time, and the children formula milk powder is drunk after being uniformly prepared, and is drunk 2 times a day.
Effects before and after drinking are evaluated, whether the children formula milk powder for improving immunity and constipation prepared in examples 1-6 has an improvement effect on children constipation is judged, and specific drinking results are shown in the following table:
TABLE 3 test drink results List
As can be seen from table 3, when a person who tries to drink the children formula milk powder for improving immunity and improving constipation prepared in examples 1 to 6 drinks, the total effective rate for improving constipation after 7 days is more than 81.25%, and the total effective rate for improving constipation after 14 days is more than 87.5%, so that the children formula milk powder has an obvious effect of improving constipation; after drinking the commercial children formula milk powder, the total effective rate for improving constipation after 7 days is only 12.5%, and the total effective rate for improving constipation after 14 days is only 18.75, so that the effect for improving constipation symptoms is not obvious. Therefore, the children formula milk powder capable of improving immunity and constipation can well improve children constipation symptoms.
Example 8 evaluation of effects of Nutrition ingredients in Children formula milk powder for improving immunity and relieving constipation
