Technical Field

The invention belongs to the field of food, and relates to modified milk powder, in particular to modified milk powder for promoting bone growth and protecting eyesight and a preparation method thereof.

Background

In the modern society, people have different understanding on health problems along with the continuous improvement of living standard. According to investigation, the height development and eyesight protection of children over 3 years old are two major problems which afflict many parents. The preschool age is an important period of growth and development of children and is also a basic period of growth and development of children, and children in the age period are likely to have the phenomena of anorexia, monophagia and insufficient calcium intake, so that the development of bones is influenced, and the height of the children in the development period is increased. Many parents often provide food containing too much fat and protein in order to allow the child to intake sufficient nutrients and promote physical development, so that the child consumes too much energy and the body becomes obese. Therefore, it is important to provide nutrition to children over 3 years old scientifically and help children to know the bone growth golden period.

In addition, with the great change of life style of people, the vision of children generally declines, and among the reasons that the health of eyes of children is influenced, the blue light of the electronic display screen becomes the chief culprit of damaging eyes. The smaller the age of the person is, the more transparent the crystalline lens is, the more the blue light of the electronic display screen penetrates, and therefore, the damage of the blue light of the electronic display screen to the eyes of the child is large. In the current society, electronic equipment such as mobile phones, computers, televisions and the like are visible everywhere, many schools or education institutions can also adopt a network course mode to carry out teaching, and in addition, animation films and electronic games attract children, so that the myopia rate of primary and secondary school students is continuously improved. Many parents have become aware of the harm of blue light of electronic devices to the vision of children, and in addition to controlling the duration of use of electronic devices by children, it is also highly desirable to help children protect their vision through proper nutrient intake.

The children formula milk powder is a nutritional supplement food which is deeply loved by children and parents at present, is delicious, and can comprehensively supplement nutrition for children. At present, the children formula milk powder on the market is various, but a product developed in two aspects of promoting the bone development of children and protecting the eyesight of children still does not exist, so that the development of the children formula milk powder which has a reasonable nutrition structure, can effectively promote the bone growth of children and simultaneously protect the eyesight of children is one of important research and development subjects at present.

The raw material components of the invention are as follows:

① vitamin D is a group of fat-soluble steroid derivatives with bioactivity, called as "sunshine vitamin", which is an important nutrient for promoting calcium absorption, assisting bone formation and maintaining bone health in children;

② vitamin K₂: vitamin K₂Can improve the unbalance state of bone tissue metabolism and has the two-way regulation effects of promoting bone formation and inhibiting bone resorption, and clinical tests prove that vitamin K₂Can effectively help calcium to enter the skeleton and greatly improve the absorption of the calcium;

③ Zinc sulfate is essential element for children growth and development, and is helpful for improving appetite;

④ calcium carbonate, calcium is a trace element necessary for the growth and development of human skeleton and teeth;

⑤ vitamin C, vitamin C helps to maintain bone and gum health;

⑥ zeaxanthin and lutein, wherein the zeaxanthin and lutein are the only nutrients existing in the eyeground, and are absorbed by the human body and specifically accumulated in the eyes to help filter harmful blue light, the body can not synthesize the zeaxanthin and the zeaxanthin by itself, but needs to be taken from the outside, clinical studies show that the 2mg zeaxanthin taken every day can obviously improve the density of the eyeground macular pigment, improve the asthenopia and further achieve the effect of protecting the eyesight;

⑦ vitamin A, vitamin A helps to maintain normal vision, and vitamin A deficiency can lead to decreased dark adaptation ability, night blindness, dry conjunctiva and xerophthalmia, and even hindered growth and development;

⑧ carrot powder is prepared from fresh carrot and is rich in nutrition, and contains abundant carotene which can be partially converted into vitamin A under the action of enzyme after entering organism;

⑨ lutein ester which is decomposed into free lutein after being absorbed by human body and has the basic function of supplementing lutein lost from human body with crystalline lutein.

Due to the adoption of the scheme, compared with the prior art, the invention has the beneficial effects that:

(1) the modified milk powder for promoting bone growth and protecting eyesight provided by the invention is prepared by strengthening vitamin D, vitamin C and vitamin K₂Calcium and zinc promote the bone development of children and help the children to grow on the basis of balanced nutrition; meanwhile, sufficient zeaxanthin, lutein, vitamin A, carrot powder and lutein ester are combined to achieve the effects of resisting blue light and protecting eyes;

(2) the modified milk powder for promoting bone growth and protecting eyesight provided by the invention is based on raw milk, is added with various vitamins and mineral substances required by growth and development of children, and added with two dietary fibers, namely galacto-oligosaccharide and fructo-oligosaccharide, so that the intestinal health of children is protected;

(3) the preparation method of the modified milk powder for promoting bone growth and protecting eyesight provided by the invention adopts a mode of combining a wet process and a dry process, and the wet production process takes fresh milk as a raw material, so that the fresh taste of the product is ensured; all the raw materials and auxiliary materials are mixed in vacuum, so that the nutritional ingredients are stable, and the uniformity of the product is good; the feed liquid can effectively control product microorganisms through heat sterilization. The dry process can effectively reduce the loss of heat-sensitive nutrient components and reduce the influence of fishy materials on the flavor and taste of the final product.

The invention is suitable for preparing the modified milk powder for promoting the growth of bones and protecting eyesight, and the prepared modified milk powder for promoting the growth of bones and protecting eyesight is suitable for children.
