Model No.: 129499-78-1
Place of Origin: CHINA
Ascorbyl glucoside, also known as 2-O-A-D-GLUCOPYRANOSYL-L-ASCORBIC ACID, referred as AA-2G. CAS number is 129499-78-1, ASCORBYL GLUCOSIDE is the most stable and best-performing L-ascorbic acid substitute by far, which is easily degraded into D-glucose and vitamin C by the action of enzymes in living organisms with high security. At present, it is mainly used as a whitening additive in a variety of high-end brand cosmetics, as well as stabilizers, quality improvers, physiologically active agents, ultraviolet absorbers and the like in the food and beverage industry, as well as chemical and pharmaceutical raw materials In the pharmaceutical industry and health products.
The industrial production of Ascorbyl glucoside cas 129499-78-1 mainly includes preparation, purification, crystallization of the three major processes. At present, biotransformation is the only way to synthesize ascorbic acid glucoside, that is, use the glucoside on glucosyl donor is transferred to the 2-position C of vitamin C by utilizing the specific transglycosylation of glycosyltransferase. During the reaction, different lengths of glucosyl groups may be attached to the 2-position C of vitamin C to produce a mixture of AA-2Gn (n = 1, 2, 3, 4, 5, C derivatives can be converted to ascorbyl glucoside by adding a glucoamylase to reduce the degree of polymerization. In addition, AA-5G, AA-6G and other AA-2G isomers tend to form in the glycosyltransferase reaction, and vitamin C and glucose-based donors remain after the reaction, so the glycosylation reaction is completed, the reaction solution to be separated and purified, and finally by crystallization method to obtain high purity ascorbyl glucoside product.
Ascorbyl glucoside produced by the relevant enterprises is not only the purity of which is more than 99%, but also the yield is considerable, but the conversion rate is still not high. In particular, the utilization rate of the raw material vitamin C is not high, and the production cost is seriously consumed. Extraction yield is low, excessive discharge of waste water, serious environmental pollution and many other issues.
