辛烯基琥珀酸酯化淀粉在微胶囊化桔油中的应用

Microencapsulation of Orange Peel Oil Using Starch Octenylsuccinate

测定了3种辛烯基琥珀酸酯化淀粉HI CAP100、CAPSUL和N LOK的酯化度,分别为0.104,0.063,0.059;随着酯化度的增大,辛烯基琥珀酸酯化淀粉的粘度降低,乳化能力和乳化稳定性增加.分别以HI CAP100、CAPSUL和N LOK作为壁材制备了微胶囊化桔油,结果表明:以酯化度最大的HI CAP100为壁材的微胶囊化桔油具有最高的效率和保留率,HI CAP100可作为包埋桔油的优选壁材.

In this study, it was found that the substitution degree Octenylsuccinate HI-CAP100, CAPSUL and N-LOK were 0.104, 0.063 and 0.059 respectively. Generally, the higher the substitution degree, the lower the viscosity and the higher the emulsifying capacity and stability. Further, it was also found that when Octenylsuccinate was used as wall material to microencapsulate the orange peel oil, higher degree of substitution was beneficial for increasing the encapsulation efficiency and retention rate. As a result, HI-CAP100 is the best wall material to microencapsulate the orange peel oil.
