Dimethyl dicarbonate(DMDC) 4525-33-1 in bulk supply

Dimethyl dicarbonate (DMDC), a food additive, can be added to a variety of foods as a preservative. Dimethyl dicarbonate (DMDC) is an organic compound possessing antimicrobial activity. DMDC is used as a cold sterilization agent for soft drinks and wines. In addition, dimethyl dicarbonate (DMDC) potentially eliminates microbial spoilage without affecting the quality attributes and nutritional components of fruit. It has a broad antimicrobial range of action against yeasts, mould fungi, and bacteria. DMDC is unstable in aqueous solution and breaks down almost immediately after addition to beverages. The European Union, Australia, and the USA have authorized its use in winemaking, and the CE Regulation No. 606/2009 authorizes the use of DMDC up to a maximum dose of 200 mg/L, but without residues found in the wine on the market. It is a powerful microbial inhibitor by inactivating cellular enzymes (Bartowsky, 2009). The EU Scientific Committee on Food, the FDA in the United States and the JECFA of the WHO have confirmed the safe use in beverages. The FDA approved its use in wines in 1988, with the maximum level being permitted set at 200 mg/L, and only if there were fewer than 500 yeast cells/mL at time of dosage.

Effects of dimethyl dicarbonate on improving the aroma of melon spirits by inhibiting spoilage microorganisms

Jiang Zhang, Xiaobin Yu, Yuxia Sun, Xueqiang Guan, Weishuai Qin, Xiang Zhang, Yan Ding, Wenhua Yang, Jianli Zhou

Journal of Food Processing and Preservation Volume46, Issue6 June 2022 e16499

The effects of dimethyl decarbonate (DMDC) on the changes in microorganisms and volatiles were systematically investigated during the fermentation of melon juice. More than 70 volatiles were detected, and most were related to fermentation.

Potency of Dimethyl Dicarbonate on the Microbial Inhibition Growth Kinetics, and Quality of Passion Fruit (Passiflora edulis) Juice during Refrigerated Storage

KA Shiekh, A Noieaid, P Gadpoca, S Sermwiwatwong

Foods 2024, 13(5), 719;

This study aimed to investigate the effectiveness of dimethyl dicarbonate (DMDC) at various concentrations (0–250 ppm) in inhibiting the growth of Escherichia coli TISTR 117 and spoilage microbes in passion fruit juice (PFJ) and its impact on the physicochemical and antioxidant quality of the juice during refrigerated storage. The highest log reduction in the total viable count, yeast/molds and E. coli was attained in PFJ samples with 250 ppm of DMDC (p ≤ 0.05) added.
