Dimethyl dicarbonate Usage
Premium Fruit Juices & Ice Teas: As the core ingredient of cold sterilization, it thoroughly kills yeast, mold, and bacteria at room temperature or even low temperatures, preserving 100% of the beverage’s original flavor and natural aroma.
Wine & Enology Industry: Added before bottling, it precisely prevents secondary fermentation in the bottle.
Carbonated & Functional Drinks: Due to its zero residue in the final product, it helps major beverage manufacturers easily penetrate the high-end health market characterized by “Clean Label” and “no artificial preservatives.”
