VITAMIN A(Cas 68-26-8) Usage
Description |
Human vitamin A is derived from the natural food. Natural vitamin A exists in dif ferent forms. In animal tissues, vitamin A is present in the form of retinoids. However, in plants, the form of vitamin A called carotenoids is contained in the green, orange, and yellow plant tissue. Vitamin A compounds such as retinol, reti nal, carotene, and so on from these foods can be converted to vitamin A in the human body. Therefore, food is the main source of vitamin A.As early as 1000 years ago, the Qian Jin Yao Fang written by Sun Simiao in Tang Dynasty recorded that animal liver can cure night blindness. This is the early recognition in vitamin A supplementation. The traditional Chinese medicine books also recorded that nourishing the liver can improve eyesight. Researches on the therapy of vitamin A deficient-diseases are mainly related to nourishing the liver and kidney, supplementing essence and blood, and activating qi |
Uses |
Vitamin A1 (retinal) is produced from (3-carotene, which can be obtained by fermentation of corn, soybean meal, kerosene, thiamin, and oc-ionone. The dry-mass after fermentation contains 120 to 150 g product/kg. |
