Chemical Information
FooDB NameVelcorin
DescriptionYeast inhibitor and preservative for alcoholic beverages especies low alcohol wines Dimethyl dicarbonate or DMDC is a colourless liquid with a sharp odour. Its primary use is as a beverage preservative and or processing aid or sterilant (INS No. 242), and acts by inhibiting the enzymes acetate kinase and L-glutamic acid decarboxylase. It has also been proposed that methoxycarbonylation of the histidine part of the enzymes alcohol dehydrogenase and glyceraldehyde 3-phosphate dehydrogenase by DMDC inhibits these essential enzymes also. Once it has been added to beverages, the efficacy of the chemical is provided by the following reactions:.
