摘要
针对葡萄皮综合利用问题,研究了温度、压力、时间对超临界流体萃取葡萄皮精油得率的影响,并进行了最佳工艺优化。结果表明,影响CO2流体萃取葡萄皮精油效率因素的主次作用为萃取时间>萃取温度>萃取压力,最佳工艺条件为萃取时间35min、萃取温度35℃、萃取压力30MPa。
Focusing on the comprehensive utilization of grape skin, the studies on the optimum conditions of the extraction of grape skin essential oil by supercritical fluid were carried out. The primary and secondary effect factors on the extraction of grape skin essential oil by supercritical fluid were as followed: time > temperature > pressure. The optimum conditions were: extraction time 35min, extraction temperature 35℃ and extraction pressure 30MPa.
