植酸/植酸钠在食品工业上的应用研究进展

植酸/植酸钠广泛存在于谷类、豆类和油料作物等中,应用非常广泛,在食品工业上可用作食品抗氧化剂、抑菌剂、护色剂、螯合剂和保鲜剂等。本文简述了植酸/植酸钠的结构、组成和理化特性,并且综述其在食品工业中的应用与研究进展。重点介绍了植酸/植酸钠在果蔬制品、饮料、发酵食品、酿造酒、油脂和脂肪制品、水产品、肉制品、焙烤制品和面制品等加工中的应用及研究进展。同时探讨了目前植酸/植酸钠在食品工业应用中存在的问题及解决对策,并对其发展趋势进行展望。指出目前高纯度植酸和固体植酸的生产成本较高,将来可以在植酸的色谱层析分离材料上进行改进。同时,为了增加植酸在油溶性食品中的应用范围,可以通过植酸的改性或借助于乳化、微乳化技术制备植酸/植酸钠的乳液和微乳液产品,是将来的发展方向。

Application Advances of Phytic Acid/Sodium Phytate in Food Industry

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.
