Product Description

Product Description

Disodium ethylen ediamine tetraacetic acid is a powerful chelating agent, preservative and antioxidant. Due to the high stability constant, with alkali metal outside most of the metal ions can generate stable complex compound, removing metal ions, or caused by the harmful effects of inhibition of boiled food water turbidity, prevent food oxidation discoloration, which works as an antioxidant, protecting color, anticorrosive, make the product quality is stable, is a very widely used stabilizer.color-protecting, quality improver, and antioxidants, Preservative and preservative.
