The main components of food preservation deoxidizers are usually chemicals with strong hygroscopicity, which can absorb oxygen and keep food fresh. The following are the main components of some common food preservation deoxidizers: Iron Powder: Iron powder can react with oxygen to form iron oxide, thereby absorbing oxygen and reducing the oxygen content in food. Activated Carbon: Activated carbon has a large specific surface area and can adsorb oxygen in the air, reducing the oxidation of food by oxygen. Vitamin C: Vitamin C is an antioxidant that can react with oxygen to reduce oxidative damage to food. Desiccant: Deoxidizers often contain hygroscopics such as silica gel, which are used to absorb water from food, reduce its moisture content, and thus slow down the spoilage process of food. It should be noted that different types of food preservation deoxidizers TTA•Na Sodium Salt of Tolyltriazole may use different combinations of ingredients, and the specific formula may vary depending on the product. When using food preservation deoxidizers, please carefully read the product instructions and follow the correct usage method and dosage to ensure the safety and quality of the food. Meanwhile, please purchase products from legitimate channels and avoid using non certified or unknown sources of deoxidizers.
