富含多不饱和脂肪酸的油脂微囊化研究进展

Advances in Microencapsulation of Oils Rich in Polyunsaturated Fatty Acids(PUFAs)

近年来,富含多不饱和脂肪酸(PUFAs)的油脂的营养价值和对人体健康的益处,使人们对其需求迅速增加。然而,PUFAs在某种程度上容易受到某些因素的影响,如温度、光照和pH值等。为了防止其在食品加工和储存过程中发生氧化和降解,微囊作为一种稳定油脂的主要方法,目前被广泛采用。本文概述可用于微囊化富含PUFAs的油脂的方法,比较各种方法的优点和局限性。总结常用3种类型的壁材及富含PUFAs的油脂的微囊化研究结果,并分析富含PUFAs的油脂微囊应用到食品中的不同特性。展望富含PUFAs的油脂微囊化的发展趋势,特别是新型的绿色材料作为壁材的应用潜能。

In recent years,demand for PUFAs-rich oils is increasing rapidly due to their nutritional value and health benefits.However,they are susceptible to certain factors,such as temperature,light and pH,to some extent.In order to prevent them from oxidation and degradation during food processing and storage,various microencapsulation strategies have been adopted to stabilize oils for better application in the food industry.In this review,the methods available for microencapsulation of PUFAs-rich oils are summarized,and the advantages and limitations of each method are compared.In addition,the research results of three kinds of wall materials and their microencapsulation of PUFAs-rich oil were summarized,and the different characteristics of PUFAs-rich oil microencapsulation applied to foods were analyzed.Finally,the development trend of oil microencapsulation rich in polyunsaturated fatty acids(PUFAs)was prospected,particularly with regard to the potential application of new green materials as wall materials.
