摘要
本文使用两种辛烯基琥珀酸酯化淀粉HI-CAP100和N-LOK为壁材制备微胶囊化薄荷油并研究了这两种壁材的界面性质和乳化稳定性。研究结果表明,HI-CAP100不仅能有效地降低油/水界面的界面张力,而且能在油/水界面上形成具有良好粘弹性且界面粘度较高的界面膜,由其制备的乳状液具有很高的乳化稳定性。由HI-CAP100为壁材制备的高载量(40%,W/W)的微胶囊化薄荷油产品的微胶囊化产率、效率均超过95%,经30℃贮存6个月,其保留率仍高达95.3%,显示出微胶囊化薄荷油具有良好的贮存稳定性。
Microcapsules containing mint oil were prepared with two kinds of starch octenylsuccinate HI-CAP100 and N-LOK. The inteffacial properties and emulsifying stabilities of two wall materials have been determined. The results showed that HI- CAP100 not only reduced the interracial tension but also formed high viscoelastic film by absorbing at oil/water interface. The emulsion formed by HI-CAP100 showed good emulsifying stability. Both the microencapsulation yield and efficiency of encapsulated mint oil with HI-CAP100 as wall material were high to 95%. Furthermore, the retention rate of encapsulated mint oil was 95.3% after stored at 30℃ for 6 months, which indicated that the encapsulated mint oil had perfect storage stability.
