Description of Dimethyl dicarbonate

Dimethyl dicarbonate (DMDC) is an organic compound which is a colorless liquid with a sharp odor at room temperature. It is primarily used as a beverage preservative, processing aid, or sterilant (INS No. 242), and acts by inhibiting the enzymes acetate kinase and L-glutamic acid decarboxylase. It has also been proposed that DMDC inhibits the enzymes alcohol dehydrogenase and glyceraldehyde 3-phosphate dehydrogenase by causing the methoxycarbonylation of their histidine components.

What is Dimethyl dicarbonate?

Part I: Introduction

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Dimethyl dicarbonate which has developed particularly rapidly in recent years. Do you know about Dimethyl dicarbonate?

The official answer: Dimethyldicarbonate, also known as Vigorin, is a preservative approved by the Ministry of Health, following the Food Sanitation Law of the People’s Republic of China and the sanitary management of food additives, with molecular formula C4H6O5, relative molecular mass 134.09, boiling point 172°C. At room temperature, it is a slightly astringent colorless liquid, usually used in beverage canning.

What’s the application of Dimethyl dicarbonate?

Dimethyldicarbonates are used in carbonated beverages, aerated and non-aerated juice beverages, tea beverages, isotonic beverages, and many other beverages. Dimethyldicarbonates are approved for use in a wide variety of beverages in Europe, the United States, and other countries. The Joint Expert Committee on Food Additives of the World Health Organization, the European Scientific Committee on Food, and the U.S. Food and Drug Administration have issued documents certifying the safety of dimethyl dicarbonate applications.

It is widely used in fruit juice, and the technology is relatively mature. The sterilization effect of DMDC in fruit juice is affected by the type of juice and strain of bacteria, and the combination of DMDC with other sterilization technologies can greatly improve the sterilization effect.

It is used for cold sterilization of the following types of beverages: fruit-flavored beverages, high energy beverages (with or without CO2), tea beverages (with or without CO2), beverages with juice (with or without CO2, juice content up to 100%).

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
