Manufacturing Vitamin A Technology
Vitamin A is also known as retinol (the aldehyde derivatives retinene) which is an unsaturated cyclic ester Alcohol. It includs vitamin A1, A2.The structure of Vitamin A1 and A2 are similar. Retinol can be synthesized by natural sources of β-carotene.In the -carotene -15,15'--dioxygenase catalysis situation, β-carotene can be broken down into two molecules of retinol Aldehyde. (ratinal, retinaldehyde can be deoxidized into retinal in the role of reduction for retinol. Therefore, β - carotene is also known as the original of vitamin A.
Vitamin A exists only in animal foods. A1 exist in mammals and liver of marine fish, and A2 exist in the liver of freshwater fish. Plant tissues haven’t been found vitamin A. if Human lack of vitamin A, it will cause a lot of problem, such as children are stunted, dry skin, dry eye, night blindness and so on.
It’s Function:
The maintenance of normal visual response. The maintenance of normal epithelial tissue morphology and reactive. The maintenance of normal bone development. Maintaining the function of skin cells, will enable the skin soft and delicate, and the effectiveness of wrinkle-free Phytosome. A lack of vitamin A would reduce the function of epithelial cells, resulting in decreased skin elasticity, dry, rough and dull.
Vitamin A is a yellow powder, insoluble in water, soluble in fats, oils organic solvents. Chemical properties are relatively stable, but prone to UV damage, should be stored in a brown bottle.
