摘要: 以β-大马酮为囊芯材料,明胶和羧甲基纤维素钠(CMC)为壁材,通过复凝聚法制备了β-大马酮微胶囊。以单因素试验为基础,通过正交试验优化了β-大马酮微胶囊制备的工艺条件。确定较佳工艺条件为:m(明胶)∶m(CMC)=9∶1,m(芯材)∶m(壁材)=1∶1,乳化速度8 500 r/min,固化剂用量0.25%,溶液pH=4.5~4.6,反应温度40 ℃。在此条件下,微胶囊的包埋率达到了97.83%±2.16%,其粒径约为30 μm,形貌圆整规则。

Abstract: β-Damascone microcapsules were prepared by complex coacervation method with β-damascone as core material and gelatin and sodium carboxymethyl cellulose (CMC) as coating materials.Based on the results from single factor experiment,the orthogonal design was used to optimize the preparation conditions of β-damascone microcapsules.The better process conditions were determined as:gelatin and CMC mass ratio,9∶1;core and coating mass ratio,1∶1;rotation speed of the emulsification,8 500 r/min;dosage of the curing agent,0.25%;pH value,4.5-4.6;operation temperature,40 ℃.Under the aforesaid conditions,the microcapsule embedding rate achieves 97.83%±2.16%;the particle size is about 30 μm,with morphology of the microcapsules round and regular.

Key words: β-damascone, microcapsules, complex coacervation method, orthogonal test
