摘要： 采用超临界CO2流体萃取技术,研究紫苏油提取工艺条件,利用β-环糊精超临界微胶囊技术,研究紫苏油超临界包合一体化工艺条件。研究结果表明,制备紫苏油微胶囊的优化条件为:紫苏籽超临界萃取紫苏油的超临界压力23MPa,β-环糊精最佳超临界包合压力12MPa;包合反应时间180min,包合反应温度55℃,萃取剂CO2流量40L/min。按此条件制得的紫苏油环糊精包合物,α-亚麻酸包合率为16.37%,最高包合物质量分数为16.42%,最高包合比(β-环糊精与紫苏油物质的量比)达1.84:1;平均包合物质量分数为13.94%,平均包合比1.55:1。

Abstract: Perilla oil was extracted with supercritical CO2 extraction, and the supercritical conditions for integrated inclusion of perilla oil was researched using β-cyclodextrin microcapsulation technology. The results show that the optimum conditions were: supercritical extraction pressure of perilla oil 23MPa, the optimum β-cyclodextrin inclusion supercritical pressure 12MPa, inclusion reaction time 180min, inclusion reaction temperature 55℃, extractant CO2 flow rate 40L/min. α-Lindenic acid inclusion rate is 16.37%, the maximum ratio of mass fraction of β-cyclodextrin/perilla oil is 16.42%, the highest molar complexation ratio (β-cyclodextrin/perilla oil) amounts to 1.84:1 (molar ratio of material), average mass fraction of perilla oil/β-cyclodextrin is 13.94%, and the average complexation ratio is 1.55:1(molar ratio of material).

Key words: perilla oil, supercritical extraction, supercritical inclusion, β-cyclodextrin, supercritical microencapsulation technology
