    摘要:

    以包埋率为评价指标,通过单因素和正交实验研究骆油微胶囊的最佳工艺条件,并评价骆油微胶囊的理化性质、贮藏稳定性和面霜的感光指标。结果表明:(1)骆油微胶囊的最佳制备工艺条件为壁芯体积比3:4、乳化剂体积比1: 2、总壁材体积分数2%、均质速度30 000 rpm,在此条件下制备的微胶囊包埋率为92.67%。(2)驼油被成功包埋在复合壁材内,包埋过程中未发生化学变化;骆油微胶囊呈圆球型,形态均匀;在低于220 ℃时,具有良好的热稳定性;其氧化稳定性远优于骆油,微胶囊化处理后能够延长贮藏时间。(3)研制的骆油微胶囊面霜pH值7.6,感官评价为21.6分,未出现分层、破乳现象,稳定性良好。

    Abstract:

    The optimal process conditions of Camel oil microcapsules were investigated using the encapsulation rate as the evaluation index, through single-factor and orthogonal experiments. The physicochemical properties, storage stability and photosensitivity indexes of Camel oil microcapsules were also evaluated. The results showed that: (1) the optimal preparation conditions for Camel oil microcapsules were as follows: wall to core volume ratio of 3∶4, emulsifier volume ratio of 1∶2, total wall material volume fraction of 2%, and homogenization speed of 30 000 rpm, and the encapsulation rate of the prepared microcapsules was 92.67%; (2) Camel oil was successfully encapsulated in the composite wall material, with no chemical changes occurring during the encapsulation process; The microcapsules of Camel oil were spherical and uniform in shape. The microcapsule of Camel oil demonstrated good thermal stability when it is below 220 ℃. The oxidation stability of Camel oil microcapsules was much better than that of unencapsulated Camel oil, significantly prolonging the storage time. (3) The pH value of Camel microcapsule face cream was 7.6, and the sensory evaluation scored 21.6 points, with no delamination or demulsification, showing good stability.
