Application and synthesis method of dimethyl dialkylate:

Introduction: Dimethyldicarbonate (dmdc), also known as vigolin, is a kind of preservative (INS No. 242) for fruit juice drinks, which is allowed to be used in the standard of food additives. At room temperature or even low temperature, dmdc has a strong ability to kill many contaminating bacteria in juice drinks, and its antiseptic effect is closely related to the inactivation of chemical book by dmdc modification of key enzyme protein in bacteria. 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, which has become one of the hot spots in the research of new non thermal sterilization technology.

Application: Dmdc is widely used in fruit juice and its technology is relatively mature. The germicidal efficacy of dmdc in fruit juice is affected by the types and strains of fruit juice, and the combination of dmdc and other germicidal technologies can greatly improve the germicidal efficacy.
