Thermostatic deoxidizers are commonly used for products coated with sugar, such as fish skin peanuts, Japanese beans, and candies. Conventional deoxidizers generate heat during the oxygen absorption process, which can cause the sugar coating to melt and affect the product’s appearance. Thermostatic deoxidizers can both absorb oxygen and prevent corrosion, and reduce the heat generated during the deoxidizer reaction, achieving the effect of low-temperature deoxygenation. They are also commonly used for rust prevention in metal instruments.
