生姜的超临界CO_2提取分离工艺的研究

The Study on Extraction of Ginger Oleoresin by Supercritical Carbon Dioxide Fluid

本文研究了超临界 CO2 流体萃取生姜的工艺 ,探讨了萃取压力、温度和时间等因素对生姜萃取率的影响 ,通过正交实验确定了生姜超临界 CO2 流体萃取最佳工艺 :生姜原料切成薄片 ,含水率 15%以下 ,萃取条件为压力2 4Mpa、温度 40℃、时间 2

In this paper,various factors which affect the technics of extracting ginger oleoresin were discussed.The best technics parameters were ascertained:material were cut into slice and water percent is under 15%,extracting pressure is 24Mpa,extracting temperature is 40℃ and extracting time is 2 h.
