摘要
研究了利用超临界CO2为萃取剂,从辣椒中萃取分离辣椒油的工艺.考察了萃取压力、萃取温度、辣椒原料颗粒大小以及CO2流量等因素对辣椒油萃取率的影响.结果表明,最佳工艺参数为:压力22 MPa,CO2流量O.3～0.4 m3/h,颗粒度30～50目,温度315 K.超临界萃取法具有工艺简单、操作安全、产品无溶剂残留、提取率高等优点.
The passage uses a set of experimental device which is self made to study the technique of separation of pepper oil from pepper with the supercritical fluid CO2 as extracting solvent. The extraction temperature, extraction pressure, size of pepper granule and flow rate of CO2 are considered here. The best experimental condition are as follows ： the pressure is 22 MPa , the flow rate of CO2 is 0.3 - 0.4 m^3/h, the size of pepper granule is 30 -50 mesh and the temperature is 315 K. From all above, we can find the supercritical fluid extraction separation has many advantages： a simple technique, safe to operate, no solvent residual and extraction rate is high etc.
