Vitamin A is a component of light-sensitive substances in visual cells, and lysine is an essential amino acid for 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, decline reproductive function, and easily get "night blindness." my country stipulates that it can be used in salad oil, sesame oil and margarine, with a usage amount of 4.0~8.0mg/kg; the maximum usage amount in solid beverages is 4-8mg/kg; and the usage amount in infant food and dairy products is 3.0~9.0 mg/kg; the maximum use amount in ice cream is 0.6-1.2mg/kg; the use amount in milk and milk beverages is 0.6-1.0mg/kg. In addition, it is fortified with retinol acetate, retinol palmitate or β-carotene. When β-carotene is used to fortify β-carotene beverages, the maximum usage amount is 20-40mg/kg; in solid beverages, the maximum usage amount is 3~5mg/kg. ;

Vitamin A is a fat-soluble vitamin. It exists in animal foods in the form of free aldehydes or esters. It is rich in fat, protein, milk, and liver. Plants do not contain vitamin A, but contain the predecessor of vitamin A (provitamin A), which is found in vegetables such as carrots and tomatoes. After being absorbed by animals, it can be converted into vitamin A. Vitamin A is necessary to maintain the body's growth, development, reproduction and cell membrane stability, and plays an important role in the visual process. There are two types of cells in the retina that sense strong light and weak light. Cells that perceive low light contain a pigment called rhodopsin, which is formed by the combination of cis-retinal and opsin in a dark environment. When exposed to light, it is decomposed into anti-retinal and opsin, and the result is the same. A nerve impulse is sent to the center to produce vision. Retinaldehyde is consumed in the body due to continuous metabolism, and needs to be supplemented by oxidized vitamin A in time. When the body is deficient in vitamin A, the synthesis of rhodopsin will decrease, which will reduce vision in low light, which is the cause of night blindness. Vitamin A is related to the normal structure and function of upper and lower cells. When it is lacking, it can cause conjunctiva, cornea dryness, inflammation, and even blindness. It can also cause damage to the respiratory tract epithelium, which is prone to respiratory infections, hair loss, and infants. Developmental delay and so on. Vitamin A oil as a nutritional supplement is a fatty oil or its concentrate obtained from the liver and pylorus of aquatic animals. Crush the fresh fish liver and pylorus, add 1-2% solution to pH 8-9. For raw materials with low oil content, add liver oil or fish oil as the diluting oil and heat for 30-60 minutes under stirring to digest and dissolve the tissues, precipitate liver stains, and centrifuge to obtain vitamin A oil. Enzymatic hydrolysis, solvent extraction, molecular distillation can also be used to concentrate, so that the concentration of vitamin A in the product is 7-8 times that of. Because vitamin A oil is insoluble in water, surfactants are usually added to make it dispersible in water. Used in sausages, margarine, bread, dairy products, fruit juice powder, peanut butter, etc. Sausage is the most suitable food to add vitamin A. It can be added during the meat grinding process. Add 2000I.U./100g (300 mg of vitamin A is equivalent to 1 million I.U.)
