The difference and application of phytic acid and sodium phytate

August 27, 2024

The main difference between phytic acid and sodium phytate is their chemical structure and application. ‌

Phytic acid is an organic matter, chemical formula C6H6O24P6, molecular weight 660, is a cyclohexanol hexaphosphate. It mainly exists in plant seeds and germ, such as rice bran and corn germ content is higher. Sodium phytate is a sodium salt form of phytic acid, chemical formula C6H6Na12O24P6, molecular weight of 923.81, is a white powder or crystalline substance.

‌ Application of phytic acid ‌ :

‌ food industry ‌ : phytic acid can be used as food additive, with antioxidant and color protection.

‌ wine industry ‌ : used as a metal removal agent.

‌ pharmaceutical industry ‌ : used for the treatment of diabetes, kidney stone and other diseases.

‌ Chemical industry, petroleum, metallurgy, daily chemical industry ‌ : used as antioxidant for oils and fats, fresh-keeping agent for food and fruits, etc.

‌ The application of sodium phytate ‌ :

‌ food industry ‌ : as antioxidant and color protectant.

‌ detergent ‌ : Toilet cleaners containing phytic acid can easily remove calcium from the urinal wall and prevent excessive surface corrosion.

‌ anti-corrosion coating ‌ : phytic acid or its salt and the product of reaction with epoxy compounds, coated on the surface of iron and steel, has the effect of anti-rust.

‌ Summarize the main differences between phytic acid and sodium phytate ‌ :

Chemical structure ‌ : phytic acid is cyclohexanol hexaphosphate, and sodium phytate is the sodium salt form of phytic acid.

‌ Application field ‌ : phytic acid is mainly used in food, medicine and chemical industry, while sodium phytic acid is more used in food additives and cleaning agents and other fields.
