Mechanism of efficiency of DMDC | DMDC can permeate through the cell membrane, and block the metabolism through reacting with the enzymes of microorganism, then achieve the purpose of sterilization. Even in very low additive amount, DMDC can effectively kill typical spoilage bacteria in beverage, and not affect the taste, flavor and color of the beverage. Furthermore, it could be rapidly and completely hydrolyzed to carbon dioxide and methanol, which are the natural ingredients of juice. |

Description:
Dimethyl dicarbonate or DMDC is a colourless liquid with a sharp odour. Its primary use is as a beverage preservative 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
DMDC is sometimes used as a preservative in wine as a replacement to sulfur dioxide, inactivating wine spoilage yeasts such as Brettanomyces. In the U.S. the FDA approved its use in wines in 1988, with the maximum permitted level being set at 200 mg/L, and only if there was less than 500 yeast cells/mL at time of dosage. Usage has also been approved in Germany (since 1978) and New Zealand. The application of DMDC is particularly useful when wine needs to be sterilised but cannot be sterile filtered, pasteurized, or sulfured.
DMDC has also been used to sterilise coffee, tea, cider, fruit wine and mead.
