摘要
利用超声波细胞粉碎仪对肉桂精油与β-环糊精进行包埋,以芯材(肉桂精油)与壁材(β-环糊精)的质量比、超声功率、超声时间、壁材(β-环糊精)与水的质量比4个因素进行单因素试验和正交试验,经正交试验确定最佳包埋条件。结果表明,肉桂精油包埋的最优条件是芯材(肉桂精油)与壁材(β-环糊精)的质量比为1∶5,壁材(β-环糊精)与水的质量比为1∶9,超声功率160 W,超声时间6 min(即120次),在此条件下肉桂微胶囊的包埋率可达21.035%。超声波有助于提高肉桂精油的包埋率。
Cinnamon oil is embedded with β-cyclodextrin （ β- CD） by the ultrasonic processors, and the single factor tests and the response surface tests are done with the ratio of core （Cinnamon oil） to wall （ β-CD） , ultrasonic power, ultrasonic time and the ratio of wall （ β-CD） to water ms the factors. Response surface tests are used to determine the optimal embedding conditions. The results show that the optimal embedding conditions are as follows： core-wall ratio is 1 ： 5; the ratio of wall material （ β- cyclodextrin） to water is 1 ： 9; ultrasonic power is 160 W; embedding time is 6 min （120 times） . Under above conditions, the embedding rate of Cinnamon oil can reach 21.035%. Ultrasound can improve the embedding rate of Cinnamon essential oil.
