柚子叶精油的超临界CO-2萃取工艺

The Technology of Extracting Volatile Oil From Pomelo Leaf With Supercritical Carbon Dioxide

用超临界CO2法对柚子叶精油进行萃取,实验结果表明,最佳工艺条件是:萃取压力12.0～15.0MPa,温度35.0～55.0℃,萃取时间1.0～1.5h,CO2流量20.0～30.0L h.所得精油产品香气清新纯正.

The volatile oil was extracted from pomelo leaf with supercritical Carbon dioxide.The results showed that the optimum conditions for the extraction are: extraction pressure 12.0～15.0 Mpa,extraction temperature 35.0～55.0 ℃,extraction time 1.0～1.5 h,carbon dioxide fluid rate 20.0～30.0 L/h.The volatile oil extracted has pure fragrance and is of high quality.
