【摘要】 采用CO2超临界流体萃取技术从肉豆蔻中分离出肉豆蔻油树脂,研究了在超临界状态下,萃取压力、CO2泵频率、萃取温度、萃取时间等因素对肉豆蔻油树脂萃取率的影响,确定最佳工艺参数为:萃取压力27MPa,CO2泵频率8Hz,萃取温度47℃,时间2h,萃取率46.12%。更多还原

【Abstract】 Nutmeg oleoresin was extracted from nutmeg by CO₂ supercritical fluid extraction technology. There are many factors which can influence the extraction rate of nutmeg oleoresin in the supercritical state, such as pressure of extraction, frequency of CO₂ pump, temperature of extraction, time of extraction and so on. The best parameters of the technology were defined: pressure-27MPa, frequency-8Hz, temperature 47℃, time-2h, the extraction rate 46.12%.更多还原
