Product details
Vitamin E Powder, also known as tocopherol, is an excellent antioxidant and nutrient with high biological activity and safe for consumption. It is widely used in the fields of medicine, health care products, food and cosmetics, and has become a hot product attracting much attention in recent years.
Vitamin E CAS 2074-53-5 is a fat-soluble vitamin whose hydrolysis product is tocopherol, which is one of the most important antioxidants. It is mostly soluble in organic solvents such as fat and ethanol, insoluble in water, stable to heat and acid, unstable to alkali, sensitive to oxygen, insensitive to heat, but the activity of Vitamin E is significantly reduced when frying. Tocopherol can promote the secretion of sex hormones, so that men's sperm vitality and increase the number of sperm; so that women's estrogen concentration increases, improve fertility, prevention of miscarriage, but also for the prevention and treatment of male infertility, burns, frostbite, capillary hemorrhage, menopausal syndrome, cosmetic surgery and other aspects.
Recently also found that Vitamin E Raw Materials can inhibit the lipid peroxide reaction in the lens of the eye, so that peripheral vasodilation, improve blood circulation, prevention of myopia and the development of myopia. Vitamin E Raw Materials phenolic hydroxyl group on the benzene ring is acetylated, ester hydrolyzed to phenolic hydroxyl group for tocopherol. People often mistakenly believe that vitamin E is tocopherol.
Applications / Functions of Vitamin E Powder
Vitamin E Powder properties and stability
Vitamin E Powder is a yellowish to yellow or yellow-green clarified viscous liquid, almost odorless, darkening with light, solidifying when left in its natural form, and melting at about 25°C. It is a fat-soluble vitamin. It is a fat-soluble vitamin, of which there are eight in nature, divided into four tocopherols and four trienyl tocopherols. We usually say Vitamin E Powder means α-tocopherol, is slightly yellowish green transparent viscous liquid, soluble in organic solvents, insoluble in water, heat stable, extremely unstable to oxygen, very easy to be oxidized.
Production method of Vitamin E Powder
Method 1: At present, the extraction process of natural vitamin E mainly includes chemical treatment, distillation, extraction, biological method, adsorption, etc. The composition of deodorized distillate is complex, and it is difficult to extract high purity of natural vitamin E directly from deodorized distillate. Deodorized distillate composition is complex, a single method is difficult to directly from the deodorized distillate to extract a higher purity of natural vitamin E, in order to obtain a high purity of natural vitamin E, the extraction process is often a combination of various methods. Foreign natural vitamin E extraction process is more mature, mainly including: saponification - extraction method, esterification - supercritical extraction method, hydrolysis - distillation method, esterification (ester exchange) - distillation method. Domestic natural vitamin extraction method is the deodorized distillate of fatty acids with lower alcohol for esterification, and then neutralization, and then the sterols in which the cold crystallization by filtration proposed. After the filtrate removes the solvent, the higher content of natural vitamin E concentrate is obtained by distillation Method 2: Synthetic VE is obtained by alkylation-condensation reaction using TMHQ and IP as raw materials. The production of synthetic VE relies heavily on the production of TMHQ and IP, and the preparation technology and production cost of these two raw materials directly affect the quality and cost of VE products.
