摘要:

以蜡质玉米淀粉为原料,经双氧水氧化和辛烯基琥珀酸酐酯化得到羧基含量为0.073%,取代度为0.019 的蜡质玉米氧化淀粉酯。将合成的蜡质玉米氧化淀粉酯作为乳化剂,应用于油脂微胶囊化中,制备出包埋率达91.99% 的粉末油脂。

关键词: 蜡质玉米氧化淀粉酯, 微胶囊化, 粉末油脂

Abstract:

Oxidized waxy maize starch esters were prepared from waxy maize starch after oxidation with hydrogen peroxide and esterification with octenyl succinic anhydride, which presented a carboxyl content of 0.073% and a degree of substitution of 0.019. The synthesized starch esters were applied to soybean oil microencapsulation as an emulsifier, and power soybean oil microcapsules with an embedding ratio of 91.99% were obtained.

Key words: oxidized waxy maize starch esters, microencapsulatation, powder oil
