Physical and chemical properties：
Sodium iron EDTA is easily soluble in water and acids, and slightly soluble in ethanol. It is stable at room temperature, can withstand high temperatures, and is not easily oxidized, but may become inactive under light. It is a stable water-soluble metal chelate, in which iron exists in a chelated state and has oxidizing properties.
Applications：
The EFA1 specification of sodium iron EDTA has a high absorption rate, which can avoid the hindrance of phytic acid and other substances to the absorption of iron supplements. Studies have shown that its iron absorption rate is 2 to 3 times that of ferrous sulfate, and it rarely causes changes in the color and taste of food.
