Technical Field

The invention belongs to the field of dairy products, and particularly relates to child milk powder beneficial to bone health and height development and a preparation method thereof.

Background

In recent years, with the improvement of the living standard of substances, the incidence rate of nutritional diseases of children is increased year by year, and the growth and development of the children are seriously influenced. The physique development speed of the infants is high in the period, the physique development of the infants is slow in the early period of the school age, the infants still continuously develop, and the demand of various nutrient substances and trace elements is obviously increased. The preschool children are in the important growth and development period, and the proper nutrition intake is given in the period, so that the growth of the height and the weight of the children is facilitated, and the important function of promoting the brain development is realized.

The height development of children is one of important indexes for measuring the health condition of children, and the children have irreversibility. The preschool age is an important stage of the height development of children, and the height development of children is mainly comprehensively influenced by factors such as heredity, nutrition, environment, diseases and the like. The trace elements are less in the body, and once deficiency or excess occurs, the growth and development, intelligence level, immune function and the like of children are affected. Calcium element is an essential macroelement in the growth and development stage of children, maintains normal calcium and phosphorus metabolism of neuromuscular, is an essential element for the growth and development of children skeleton, and the deficiency of calcium causes poor bone growth, parathyroid hormone functional secretion disorder, skeletal development retardation and the like. The supplement of vitamin D, calcium and milk can promote the growth of children height. The zinc element belongs to metalloenzyme and participates in the biological function of human body, if the zinc element is lacked in the growth process of children, the growth speed becomes slow, the appetite is reduced, the attention is dispersed, the memory is reduced, the immunity of the children is low, and the sexual maturity and the skeletal maturity of the children can be influenced by serious people. If B vitamins are absent, gastrointestinal motility is reduced and digestion and absorption of food are hindered. Researches show that the height and the weight of children are positively correlated with the intake of nutrients and trace elements, and the intake of nutrients and trace elements of children before school age affects the height and the weight. Therefore, it is essential for children to supplement required nutrient elements in a proper manner.

After the rats are purchased, the rats are adapted to the environment for one week, water and diet are freely taken, the temperature of a feeding room is 25 ℃, the humidity is 60%, and the rats are alternately used day and night for 12 hours. Rats were divided into ten groups of 20 rats each, and each group was perfused with a sample and purified water.

Bone growth test: and (3) forcibly filling the milk powder for feeding, wherein the stomach filling amount is 0.1ml/10g, injecting the fluorescent matrix-tetracycline into the abdominal cavity after 6 days, injecting the fluorescent matrix-tetracycline for the 2 nd time on day 8, intoxicating the rat with the 10 th rhizoma gastrodiae to death, completely stripping the tibia out, measuring the distance between the proximal articular surface and the distal articular surface of the tibia by using a vernier caliper, namely the length of the tibia fed for 10 days, and taking the average value of 3 measurements. In addition, the length of the tibia was measured after injection of the fluorescent matrix tetracycline at 56d and 60d, respectively, and 60 d. Tibial elongation is measured by taking the removed tibia as a bone slice, immunofluorescent staining the tetracycline, and measuring the distance between the fluorescent bands and the growth plate for tibial elongation between 2 d.

Rat bone densitometry test: a weaning Wistar male rat with SPF level born for about 4 weeks is selected, the weight of which is 60-75 g, and purchased from Beijing Huafukang Biotechnology GmbH. After the rats are purchased, the rats are adapted to the environment for one week, water and diet are freely taken, the temperature of a feeding room is 25 ℃, the humidity is 60%, and the rats are alternately used day and night for 12 hours. Rats were randomly divided into ten groups of 20 rats per group by weight, and the test samples and purified water were separately fed with a gastric feeding amount of 0.1ml/10g, sacrificed after 3 months, femurs were removed, and bone densities of the mid-point of the left femur and distal end of the femur were measured using a peripheral dual-energy X-ray bone densitometer.

And (3) test results: the test results are shown in tables 2 and 3.

As can be seen from Table 2, after rats eat the milk powder for children which is provided by the invention and is beneficial to bone health and height development, the growth length of the tibia after 10 days and 60 days is obvious, which fully indicates that the formula milk powder can effectively promote bone growth. As can be seen from Table 3, after the children milk powder beneficial to bone health and height development provided by the invention is canned for 3 months, the femoral midpoint density and the distal end bone density of a rat are both remarkably improved, which shows that the formula milk powder provided by the invention has obvious promotion effects on bone growth and bone density enhancement. Comparative examples 1 to 5 changed the kinds of milk powder, prebiotics and unsaturated fatty acids, respectively, compared with example 3, but the bone growth length and bone density growth of rats were reduced to different degrees, which indicates that the formula of the present invention is optimized, and the effect is reduced by changing the formula components.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Those skilled in the art will recognize that changes may be made to the embodiments described above without departing from the spirit and scope of the invention. Therefore, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the technical spirit of the present invention are covered by the claims of the present invention.
