Description
Sodium Erythorbate is a kind of antioxidant, which acts as preservatives by inhibiting the effects of oxygen on food, and is beneficial to human health.
It has been confirmed as a statutory food additive by FAO and WHO. Taking starch as its main ingredient, it is produced by the fermentation of microorganism. Sodium Erythorbate could keep food color and natural flavor, and prolong the shelf time, without any side effects. It is widely used in the production of foods, such as meat products, beer, beverages, canned fruits and vegetables, confiture, frozen fish and so on.

Appltcatton
Sodium Erythorbate is White crystalline powder,Slightly salty. It is quite stable in the air in a dry state. But in solution, it will deteriorate in the presence of air, trace metals, heat and light. Melting point above 200 ℃ (decomposition). Easily soluble in water (17g / 100m1). Almost insoluble in ethanol. The pH value of the 2% aqueous solution is 5.5 to 8.0.
Used as food antioxidants, anti-corrosion color additives, Cosmetic antioxidants. It can consume oxygen in cosmetics, reduce high-valent metal ions, transfer the redox potential to the reduction range, and reduce the generation of undesirable oxidation products. It can also be used as anticorrosive color additive.
