摘要: 以β-环糊精为壁材,采用单因素试验和Box-Behnken试验对超声法制备苘麻籽油微胶囊的工艺进行优化。结果表明:最佳工艺条件为超声功率75W、包埋温度62.3℃、包埋时间88min,在此条件下实际包埋率为81.35%,与模型预测值之间具有较好的拟合性;在3个因素中,包埋温度和包埋时间对包埋率的影响极显著,超声功率影响显著。该方法简单可行,是一种制备苘麻籽油微胶囊的较好方法。

Abstract: The essential oil of Semen Abutili was extracted by petroleum ether under ultrasonic assistance and microencapsulated using β-cyclodextrin (β-CD) as the wall material. Based on one-factor-at-a-time experiments, Box-Behnken experimental design combined with response surface analysis was applied to optimize process conditions for the extraction and microencapsulation of the oil. The optimal process conditions were determined as follows: 75 W ultrasonic power, 62.3℃ encapsulation temperature and 88 min encapsulation time. Under the optimal conditions, the observed value of encapsulation rate was 81.35%, which was in good agreement with the predicted value. Encapsulation rate was highly significantly affected by encapsulation temperature (P<0.01) and time (P<0.01). Ultrasonic power presented a significant effect (P<0.05).
