摘 要：
为优化超声波辅助羟丙基-β-环糊精(HP-β-CD)包埋椒目α-亚麻酸工艺,考察超声功率、超声时间、无水乙醇+混合脂肪酸:HP-β-CD质量比对包合率的影响。结果表明,最优工艺条件为超声功率300W、超声时间20min、无水乙醇+混合脂肪酸:HP-β-CD质量比1:8,此条件下包合率达90.26%,可实现甜.亚麻酸的安全无毒分离。

Optimization of Ultrasonic-Assisted Hydroxypropyl-β-Cyclodextrin Embedding of α -Linolenic Acid from Zanthoxylum bungeanum Maxim Seeds
摘 要：
In order to optimize the ultrasonic-assisted hydroxypropyl-β-cyclodexVin (HP-β-CD) embedding of α -linolenic acid from Zanthoxylum bungeanum Maxim seeds, the effects of ultrasonic power, ultrasonic treatment time and mass ratio between absolute ethanol plus mixed FFAs and HP-β-CD on embedding efficiency were explored. The results indicated that the optimal embedding conditions were ultrasonic power of 300 W, ultrasonic treatment time of 20 min and (ethanol + FFAs)-to-HP-β-CD mass ratio of 1:8. Under these conditions, the embedding rate of a-linolenic acid reached up to 90.25%, which allowed the safe and non-toxic separation of α-linolenic acid.
