摘要
研究了超临界 CO2 抽提去除绵羊皮中油脂的新技术。试验了皮样水分、CO2 浓度、CO2 流速和抽提时间等因素对脱脂率的影响。结果表明 :绵羊皮脱脂率随着 CO2 浓度、CO2 流速和抽提时间的增大而提高 ;随着水分的增加而降低。在最佳试验条件下 ,脱脂率可达 94 %以上。
A novel technology in degreasing sheepskins by supercritical CO 2 extraction has been studied and the effects of moisture content of the samples, CO 2 density, CO 2 flow rate and extraction time on the degreasing efficiency of sheepskins by this technology were tested. The results show that the degreasing efficiency decreased with moisture content in the skin and increased with CO 2 density,CO 2 flow rate and extraction time. Degreasing efficiency levels up to 94% in the optimum conditions.
