Documented Uses

Potential preservative in unstandardized water-based non-alcoholic beverages (ready-to-drink teas, fruit-flavored sport drinks, energy drinks, and carbonated flavored soft drinks).
Dimethyldicarbonate (DMDC) is used as a cold sterilization agent for soft drinks and wines. It has a broad antimicrobial range of action against yeasts, mold fungi, and bacteria.
To help prevent fermentation in finished wines; to control spoilage yeast such as Brettanomyces; to decrease the amount of sulfur dioxide used in wines; to reduce warehouse holding time in early-to-market wines /Velcorin/
Food Additives -> PRESERVATIVE -> JECFA Functional Classes
Dicarbonic acid, 1,3-dimethyl ester: ACTIVE
Dimethyldicarbonate (DMDC) is unstable in aqueous solution and breaks down almost immediately after addition to beverages. The principal breakdown products in wine and aqueous liquids are methanol and carbon dioxide. Dimethylcarbonate (DMC) and methyl ethyl carbonate (MEC), as well as carbomethoxy adducts of amines, sugars, and fruit acids, are also formed in minor amounts. In the presence of trace quantities of ammonia or ammonium ions (e.g. in wines), DMDC forms trace quantities of methylcarbamate (MC).
