Velcorin, also known as dimethyl dicarbonate (DMDC), is a chemical compound commonly used as a microbial control agent in the beverage industry. It is a colorless liquid that is added to beverages such as wine, beer, and fruit juices to inhibit the growth of yeast, molds, and bacteria. Velcorin works by breaking down microbial cell walls and disrupting their metabolic processes, ultimately preventing spoilage and extending the shelf life of the product.
Velcorin is dimethyl dicarbonate, it is certified Parve Kosher.
Velcorin has been looked at in detail by many countries registration authorities and also e.g. by JECFA (joint FAO/WHO expert committee on food additives) and there have been no objections, so it should be considered safe.
