EXCELLENT MICROBIAL CONTROL AGENT / NO EFFECTS ON FLAVOR
One of the biggest challenges for the beverage production is to prevent the product contamination by microorganisms such as yeasts, bacteria or mould during the process of mixing, filling or capping, etc. Microbiological stabilization of beverages can be processed via both physically (e.g. filtration, thermal processing as hot filling or pasteurization or cold sterile filling as aseptic or white room, etc.) or chemical preservation (e.g. persistent preservatives as sorbates, benzoates or DMDC).DMDC is used as a preservative to inactivate residual spoilage organisms in beverages but leaving no DMDC residue.
The application of DMDC is approved for a wide range of soft drinks as well as wines in more than 90 countries. The beverage and wine manufacturers are responsible for ensuring the compliance with all local legal requirements and trade regulations.

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.
