耐酸型微胶囊粉末油脂配方的研究

Study on Formula of Acidproof Microencapsulated Oil Powder

在对乳化剂配方进行筛选、实验研究的基础上,应用喷雾干燥方法,制备了耐酸型微胶囊粉末油脂并对其部分性能进行了实验、评价。结果表明,应用此配方制备的微胶囊粉末油脂在pH为2的介质中其复原乳状液乳化稳定性好,无任何分层现象,亦无粒子挂壁,并且其油脂包埋率达97.5%。

Acidproofmicroencapsulated oil powder was prepared by spray-drying technique on the basis of a screening and testing research on the formula of emulsifier, and its partial performances were tested and evaluated. The results showed that in the medium at pH 2, the emulsion stability of reverted emulsion of the prepared microencapsulated oil powder is good, no layer phenomenon and phenomenon of particle hanging on wall, and the embedding rate reaches 97.5%.
