摘要
研究了超临界二氧化碳萃取橘皮油的工艺,分别讨论了萃取时间、萃取温度、萃取压力和原料粉碎度对橘皮油萃取得率的影响。试验结果:萃取橘皮油的最佳工艺条件为萃取时间为1.5h,萃取温度为55℃,萃取压力为40MPa,原料粒度为0.42mm,最高出油率为6.74%。所得橘皮油色泽为淡黄色,香气浓郁。
Citrus peel oil from the citrus by the Supereritical CO2 technique was studied. The effects of time, temperature, pressure and grind degree on extraction of citrus peel oil were determined. The optimal conditions were time 1.5h, extracting temperature 55℃, extracting pressure 40Mpa and grind degree 0. 42mm, and the ratio of extraction was 6.74%. The color was straw yellow, had full-bodied perfume.
