Description

A kind of formula milk powder for improving intelligence and promoting bone growth of children and preparation method thereof

technical field

The invention belongs to the technical field of milk powder preparation, and in particular relates to a formula milk powder for improving intelligence and promoting bone growth of children and a preparation method.

Background technique

At present, the height and weight of children aged 3 to 15 have increased steadily, and their brain development has entered the second peak. Studies have shown that a person’s brain volume is twice as large at birth at 6 months, three times as large at the age of two, and almost reaches the capacity of an adult by the age of 6, Therefore, 3 to 15 years old is the golden period for children's physical and intellectual development. During this period, the healthy growth of children requires sufficient energy and various nutrients that are beneficial to physical and mental development. The substances needed for the growth of children at this stage are not like infants and young children who can be supplemented by comprehensive breast milk, but mainly need comprehensive nutritional supplements through formula milk powder to meet the needs of body growth and development.

Children are in the developmental stage, and their healthy growth is easily affected by internal and external influences. In particular, for example, children's gastrointestinal tract is not yet fully developed, and is easily affected by changes in the external environment, improper diet, etc., causing gastrointestinal discomfort. Gastrointestinal discomfort is a common disease in children's growth, which affects children's eating and gastrointestinal absorption, resulting in poor nutrient absorption and calcium absorption in children, affecting children's healthy growth. At the same time, because the developmental stage of children is also the learning stage, it is easy to cause eye fatigue and decreased vision due to improper use of the eyes.

Milk powder is made from fresh milk or goat milk, which is processed by freezing or heating to remove almost all the water in the milk, and then adding appropriate amount of vitamins and minerals after drying. based on formulated dairy products.
