摘　　要：超临界CO_(2)萃取所得的花椒精油含有花椒挥发物、花椒酰胺类物质等,由于花椒精油含有花椒酰胺类物质,其滋味较麻,因此不能用于日化产品中。采用无毒、无害、高效的分子蒸馏技术对其进行脱麻,避免了传统有机溶剂法对花椒精油品质的破坏,花椒精油净油得率可达31.1%。通过试验表明分子蒸馏法提纯花椒精油可以得到具有香味且不含麻味的花椒精油净油产品,其工艺条件如下:蒸馏温度160℃,蒸馏压力180 Pa,物料流量90 m I/min,刮膜转速60 r/min。The essential oil of Zanthoxylum bungeanum by supercritical CO_(2) extraction contains Zanthoxylum bungeanum volatiles、prickly ash amide substances,as Zanthoxylum essential oil contains Zanthoxylum amides,Is taste is more numb.Therefore can not be used in daily chemical products.Using non-toxic,harmless and efficient molecular distillation technology to remove hemp.The traditional organic solvent method can avoid destroying the quality of Zanthoxylum bungeanum essential oil,he yield of prickly ash essential oil was 31.1%.The experiment showed that the pure oil of Zanthoxylum bungeanum could be obtained by molecular distillation.The process conditions were as follows:the distillation temperature was 160℃,Distillation pressure 180 Pa,Material flow rate 90 mI/min.The speed of scraping film was 60 r/min.
