摘要
建立了一套超临界流体萃取实验装置,系统研究了超临界二氧化碳萃取大蒜油的实验工艺,考察了萃取压力、萃取温度、流体流量以及原料厚度对大蒜油收率的影响,确定了各因素对萃取率指标影响的主次程度依次为:压力、流体流量、原料厚度、温度;确定了实验范围内的最佳萃取工艺条件为:压力25MPa、温度40℃、CO2流量0.3～0.4m3·h-1、大蒜厚度1～0.5mm。
The supercritical fluids extraction experimental equipments were established, and the experimental processes of supercritical CO2 extraction for garlic oils were systematically investigated. The effects of extraction pressure, extraction temperature, flow rate and feed thickness on extraction were investigated. The order of the effects of these factors on extraction index was determined, which was: the pressure, the flow rate, the feed thickness, and the temperature. The optimum extraction process conditions in experiment ranges were determined, which was: pressure 25MPa, temperature 40℃, flow rate of CO2 0.3～0.4m3·h-1,thickness of garlic 1～0.5mm.
