Disodium EDTA

Disodium ethylenediaminetetraacetic acid (also known as disodium EDTA) is used in food, medicine, cosmetics and other products. According to GB2760-2014, food-grade disodium ethylenediaminetetraacetic acid can be used as stabilizer, coagulant, and antioxidant With preservatives, it can play a role in color protection, anti-oxidation, anti-corrosion synergy and stability. It is a powerful chelating agent. Because of its high stability constant and extensive coordination properties, it can almost interact with most metal ions other than alkali metals (such as iron, copper, calcium, magnesium and other multivalent ions) Chelation generates stable water-soluble complexes, eliminating metal ions or harmful reactions caused by them.

EDTA disodium specifically has the following three functions: 1. Use its complexation to prevent harmful reactions such as discoloration, deterioration, turbidity, and oxidation loss of vitamin C caused by metal ions. 2. As a water treatment agent, it can prevent the adverse effects of calcium, magnesium, iron, manganese and other metal ions in the water. 3. The trace metals (iron, copper, etc.) in the fat can promote the oxidation of fats. This product can complex with trace metal ions to improve the anti-oxidation of fats and prevent food discoloration.

Currently widely used in beverages (except packaged drinking water) (0.03g/kg), jam, vegetable puree (sauce), except tomato sauce (0.07g/kg), compound seasoning (0.075g/kg), sweet potato preserved fruit , Pickled vegetables, canned vegetables, canned nuts and seeds, canned grains (0.25g/kg).

For example, it can be used for pickling sauerkraut and kimchi to make the sauerkraut color uniform and bright, the storage period is significantly prolonged, and the color fixation and preservation effect is significantly better than that of VC and phosphate; it can be added to canned vegetables and mushrooms with water before sterilization. Maintain the color of the product, prevent the turbidity of the boiled water, and protect the color; in various sauces and seasonings, it can delay the oxidation and rancidity of oils, and has anti-corrosion synergistic effects, which can prevent the seasonings from graying and flavor changes; it can also be used in carbonated drinks, Used as a color protectant and stabilizer in fermented malt beverages, it inhibits the deterioration of the beverage by catalytic oxidation of metals and keeps the beverage flavor unchanged.
