Food Additives

Dimethyl dicarbonate (DMDC) is a preservative of fruit and vegetable juice beverage, and it’s a non-thermal bactericidal additive. The results show that dmdc has a rapid and broad-spectrum effect of sterilization at room temperature or even low temperature, and it can be decomposed into trace methanol and carbon dioxide in water quickly, which will not affect human health and product quality.

Product name: Dimethyl Dicarbonate (DMDC)

Molecular Formula: C4H6O5Molecular Weight: 134.087

CAS No.: 4525-33-1

Description

Dimethyl Dicarbonate (DMDC) is Colorless liquid.

Application

Dimethyl dicarbonate (DMDC) is a kind of preservative for fruit juice drinks, which is allowed to be used in China’s food additive standard (INS No. 242). At room temperature or even low temperature, Dimethyl dicarbonate (DMDC) has a strong ability to kill many contaminating bacteria in juice drinks, and its antiseptic effect is closely related to the modification and inactivation of key enzyme proteins in the bacteria by DMDC. Compared with other physical sterilization technologies, DMDC has the advantages of low cost, simple and safe operation, and does not affect the taste, smell and color of the product. It has become one of the hotspots in the research of emerging non-thermal sterilization technologies.

Dimethyl dicarbonate can be used in carbonated beverages, carbonated or non-carbonated juice beverages, tea beverages, isobaric beverages and many other beverages. In Europe, the United States and some other countries, dimethyl dicarbonate is approved to be widely used in various beverages. Important authorities such as the World Health Organization’s Joint Expert Committee on Food Additives (JECFA), the Scientific Committee for Food of EEC (SCF) and the U.S. Food and Drug Administration (FDA) have issued documents proving the safety of the application of dimethyl dicarbonate.

Dimethyl dicarbonate is commonly used for cold sterilization of the following types of beverages:

1) Fruity drinks

2) Energy drinks (with or without carbon dioxide)

3) Tea beverages (with or without carbon dioxide)

4) Fruit juice beverages (with or without carbon dioxide, the juice content reaches 100%)

5) De-alcoholic wine
