Abstract:
Phytic acid/sodium phytate is widely spread in cereals, beans, oil crops and so on, which is widely applied in the food industry used as the food antioxidant, antibacterial agents, color protection agents, chelating agents and preservative. In this paper, the structure, composition, physical and chemical properties of phytic acid/sodium phytate were briefly reviewed, and the application and research progress of phytic acid/sodium phytate in the food industry were reviewed. The application and research progress of phytic acid/sodium phytate in the processing of fruit and vegetable products, beverages, fermented foods, brewed wine, fat and fat products, aquatic products, meat products, bakery products and pasta products were mainly introduced. At the same time, the existing problems in the application of phytic acid/sodium phytate in food industry and the countermeasures were discussed, and the development trend of phytate/sodium phytate was prospected. It was pointed out that the current high-purity phytic acid and solid phytic acid had high production costs and could be improved by phytic acid chromatographic separation materials in the future. In the meantime, in order to increase the application range of phytic acid in oil-soluble foods, phytic acid/sodium phytate emulsions and microemulsion products can be prepared by the modification of phytic acid or by the means of emulsification and microemulsification technology, which is the future development direction.
