Application
1. It can maintain vision and promote bone growth, maintain the integrity and integrity of epithelial structure, prevent night blindness, improve vision, maintain strong teeth, promote bone growth, promote children's height, keep skin moist, ensure normal hair growth, and increase resistance.
2. Vitamin A is a constituent of the light-sensitive substances in the visual cells. Lysine is an essential amino acid in the human body, which can maintain the integrity and health of the epithelial tissue structure, and promote the growth and development of the body. When it is lacking, it will hinder growth and development and decline reproductive function. Commonly used for the prevention and treatment of child dysplasia, dry eye, night blindness, dry skin, and decreased resistance of the eyes, respiratory tract, urinary system, and intestines to infection. China stipulates that it can be used for salad oil, sesame oil and margarine, the amount used is 4.0 ~ 8.0mg / kg; the maximum amount used in solid drinks is 4 ~ 8mg / kg; the amount used in baby food and dairy products is 3.0 ~ 9.0mg The maximum amount used in ice cream is 0.6 ~ 1.2mg / kg; the amount used in milk beverage is 0.61.0mg / kg. When beta-carotene is used to fortify beta-carotene beverages, the maximum usage is 20 to 40 mg / kg; in solid beverages, the maximum usage is 3 to 5 mg / kg.
3. Vitamin A is a component of the light-sensitive substances in the visual cells, which can ensure the integrity and health of the epithelial tissue structure, and promote the development and growth of the body. When it is lacking, it will hinder growth and development and decline reproductive function. Retinol acetate is usually added to feed.
4. Nutritional supplements. Applicationd as a nutritional additive in cosmetics, can prevent rough skin, promote normal growth and development, and can be used in cream emulsions.
 
Package: 25kg/drum, can also be designed according to customer requirements.
