Functions of sodium erythorbate antioxidant
The competitive combination of oxygen delays the initiation of oxidation;

Destroy free radicals or combine with free radicals to stop chain reaction transmission;

Catalysts that inhibit the oxidation process and stabilize peroxides to delay or stop the oxidation reaction.

Advantages of antioxidant food preservative
01
It can reduce the impact of metal on the catalytic degradation of materials, improve the long-term thermal stability of materials.

02
Block the high molecular weight and extraction resistance, and prevent the rise of acid value or viscosity of lubricating oil and fuel oil
