1. Phytic acid is used as chelating agent, antioxidant, preservative, water softening agent, fermentation accelerator, metal anti-corrosive agent, etc.

2. Phytic acid is widely used in food, medicine, paint coating, daily chemical industry, metal processing, textile industry, plastics industry and polymer industry.

3. Phytic acid is used in the food industry for the preservation and protection of fruits, vegetables and aquatic products, as well as metal anti-rust and corrosion inhibitor.

Application

Phytic acid is found within the hulls of nuts, seeds, and grains. Phytic acid has a strong binding affinity to important minerals, such as calcium, iron, and zinc, although the binding of calcium with phytic acid is pH-dependent. The binding of phytic acid with iron is more complex, although there certainly is a strong binding affinity, molecules like phenols and tannins also influence the binding. When iron and zinc bind to phytic acid they form insoluble precipitate and are far less absorbable in the intestines. This process can therefore contribute to iron and zinc deficiencies in people whose diets rely on these foods for their mineral intake, such as those in developing countries and vegetarians.
