Description

Technical Field

[0001] The invention belongs to the technical field of food, and particularly relates to a nutritional composition for promoting the growth and development of children and a preparation method thereof. Background Art

[0002] Nowadays, people's living standards are improving day by day. Parents will spend most of their time on their children's study and physical health after work. Children's growth and development are of concern to every parent. Now there are comprehensive measurement methods for children's bone growth and development. We can clearly know the reasons why children's growth and development are not up to standard. However, how to promote children's growth and development is indeed a topic worthy of study.

[0003] Children's growth and development are affected by many factors, such as genetics, sleep, exercise, nutrition, etc. Most parents are familiar with this knowledge. Genetic factors are uncontrollable. Therefore, parents usually choose to work hard on sleep, exercise, nutrition, etc., but the choice of nutritious food is a headache for parents.

[0004] In order to promote children's growth and development, there are various nutritional foods on the market. Most of the nutritional foods focus on calcium supplementation. However, calcium supplementation alone is not enough to promote children's growth and development. In addition, some nutritional foods contain additives, which are not easy to absorb and have no obvious effect on promoting children's growth and development. Parents will also worry about the safety and health of their ingredients.

[0005] Pork liver has high nutritional value and is rich in iron, which can prevent and treat iron deficiency anemia. It is rich in vitamin A and zinc, which can effectively promote children's growth and development. The rich variety of vitamins and minerals in pork liver can enhance human immunity. There are foods such as pork liver powder on the market, but the taste of pork liver is not easily accepted by children. Therefore, children do not eat pork liver powder well, and parents' purchasing power for pork liver powder is also reduced. Summary of the invention

[0006] The present invention provides a nutritional composition for promoting the growth and development of children and a preparation method thereof, aiming to overcome the problems of the existing nutritional composition having a single ingredient, insufficient effect of promoting the growth and development of children, containing additives, and low acceptance of the existing nutritional composition containing pig liver, and to provide a nutritional composition for promoting the growth and development of children which is rich in ingredients, does not contain additives, is highly accepted by children and has a significant effect, and a preparation method thereof.

[0007] The nutrient composition for promoting the growth and development of children provided by the present invention contains cucumber seed extract, L-lysine and L-tryptophan. The cucumber seed extract is rich in calcium and phosphorus, and the ratio of calcium to phosphorus is very suitable for being absorbed by the human body, and can well promote bone growth and development. L-lysine has the effects of promoting the growth and development of children, enhancing human immunity and improving human resistance, and L-tryptophan has the effect of improving sleep quality. Therefore, adding cucumber seed extract, L-lysine and L-tryptophan can all help promote the growth and development of children. In the present invention, cucumber seed extract, L-lysine and L-tryptophan are added at the same time, and the three have a synergistic effect. Adding cucumber seed extract, L-lysine and L-tryptophan at the same time has a better effect of promoting the growth and development of children. In addition, in the present invention, hydroxypropyl β-cyclodextrin-encapsulated pig liver extract is added to the nutritional composition. The pig liver extract is encapsulated by hydroxypropyl β-cyclodextrin, which can not only improve the utilization of active ingredients in the pig liver extract, but also hydroxypropyl β-cyclodextrin can effectively improve the taste and flavor of the pig liver extract, making it more acceptable to children. In addition, in the present invention, hydroxypropyl β-cyclodextrin-encapsulated pig liver extract and β-cyclodextrin are added at the same time, and β-cyclodextrin can further enhance the utilization of active ingredients in the hydroxypropyl β-cyclodextrin-encapsulated pig liver extract, further improve the taste and flavor, and the two have a certain synergistic effect on promoting the growth and development of children.

Spray-drying the pig liver extract hydrolyzate to obtain a pig liver extract.

[0051] Table 1 Raw material ratio of the nutritional composition for promoting children's growth and development

[0052] It should be noted that the raw materials used in the nutritional composition for promoting children's growth and development provided by the present invention are all edible for children, and the preparation method also meets the relevant requirements; the nutritional compositions for promoting children's growth and development involved in the embodiments and comparative examples of the present invention are all edible, and have different effects on promoting children's growth and development, but have no side effects.

[0053] Finished product sample testing 20 passers-by were randomly invited to taste the nutritional compositions prepared according to the formulas of Example 6, Comparative Example 7 and Comparative Example 9 shown in Table 1, and the quality of each group was scored from 1 to 10, including taste and flavor, and the average was obtained to obtain Table 2.

[0054] Table 2 Improvement of taste and flavor of the nutritional composition of the present invention

[0055] It can be seen from the data in Table 2 that the present invention adds hydroxypropyl β-cyclodextrin-encapsulated pig liver extract to the nutritional composition, compared with directly adding the pig liver extract to the nutritional composition, the hydroxypropyl β-cyclodextrin encapsulation of the pig liver extract significantly improves the taste and flavor of the nutritional composition. Furthermore, the nutritional composition to which hydroxypropyl β-cyclodextrin-encapsulated pig liver extract and β-cyclodextrin are simultaneously added has a better taste and flavor than that to which only hydroxypropyl β-cyclodextrin-encapsulated pig liver extract is added. Adding hydroxypropyl β-cyclodextrin-encapsulated pig liver extract and β-cyclodextrin simultaneously to the nutritional composition makes the nutritional composition for promoting children's growth and development have a better taste and flavor, better acceptance among the public, and higher quality.

[0056] In order to test the effect of the nutritional composition for promoting children's growth and development described in the present invention in promoting children's growth and development, 160 4-year-old children (male) were invited to participate in this test, the initial height of each child was measured and recorded, and the 150 children were divided into 15 groups, and each group consumed 10 g of the nutritional composition described in Table 1 once a day. The other 10 children were the 16th group and did not consume the nutritional composition for promoting children's growth and development described in the present invention. After 1 month, the height of the 160 children was measured, and the average height growth value of each group was calculated.

[0057] Table 3 Effect of the nutritional composition of the present invention on promoting growth and development of children

[0058] It can be seen from Table 3 that after the children consumed each formula for one month, the height growth value of the 10 children who consumed the nutritional composition of the formula described in Example 2 reached the maximum. By comparing Example 6 with Comparative Examples 1-6, it can be seen that the nutritional composition to which cucumber seed extract, L-lysine and L-tryptophan are added at the same time has the best effect on promoting children's growth and development. It can be seen that the combined use of cucumber seed extract, L-lysine and L-tryptophan has a synergistic effect on children's growth and development. Adding any one of them alone or adding any two of them cannot achieve the effect of adding the three raw materials of cucumber seed extract, L-lysine and L-tryptophan at the same time.

[0059] By comparing Example 6 with Comparative Examples 7-8, it can be seen that adding hydroxypropyl β-cyclodextrin-encapsulated pig liver extract and β-cyclodextrin at the same time can better promote the growth and development of children, and adding either one alone cannot achieve the corresponding promotion effect.

[0060] By comparing Example 6 with Comparative Example 9, it can be seen that by using hydroxypropyl β-cyclodextrin to encapsulate the pig liver extract, the pig liver extract has a higher effect in promoting the growth and development of children. The pig liver extract after hydroxypropyl β-cyclodextrin inclusion has higher bioavailability and can exert its maximum value. In addition, the pig liver extract encapsulated by hydroxypropyl β-cyclodextrin has a better taste and flavor than the pig liver extract, and is more conducive to children's acceptance. It also reduces psychological resistance to the nutritional composition. Therefore, adding the pig liver extract encapsulated by hydroxypropyl β-cyclodextrin has a significant improvement effect on promoting the growth and development of children compared to adding the pig liver extract.

[0061] At the same time, the pig liver extract contained in hydroxypropyl beta-cyclodextrin and beta-cyclodextrin can further promote the growth and development of children in a coordinated manner. In addition, the invention solves the technical problem that the existing pig liver extract has a poor taste and texture, and has good commercial value.

[0062] In summary, the nutritional composition for promoting the growth and development of children involved in the present invention is rich in ingredients, does not contain additives, and has high acceptance by children.
