摘要: 主要对超临界CO2流体提取技术从塔拉籽中提取塔拉籽油的工艺与方法进行优化和油分品质分析。采用3组平行单因素实验确定塔拉籽油的提取工艺条件,以塔拉籽油提取率为指标,在单因素实验的基础上研究提取时间,提取温度,提取压强对塔拉籽油提取率的影响,经分析确定最佳提取工艺条件为:提取时间120 min,提取温度45℃,提取压强35 MPa。通过3组重复实验验证单因素实验结果,表明在最佳提取条件下塔拉籽油的实际平均提取率为21.07%与单因素实验中的结果接近较为吻合,所得提取条件现实可靠。提取的塔拉籽油呈现出透明的淡黄色,为干性油脂,不饱和脂肪酸含量较高,表明该法提取塔拉籽油具有较高的营养价值和可利用价值。

Abstract: We used three groups of parallel single factor experiment to determine Tara seed oil extraction process conditions to improve Taraoil yield. We focused on supercritical CO2 fluid extraction technology to extract Tara oil, optimized the Tara oil’s extraction process and methods, and analyzed the Tara oil quality. With oil extraction yield as index, on the basis of a single factor preliminary experiments, we studied extraction time, extraction temperature, extraction pressure, and their interactions on Tara seed oil extraction yield systematically. The optimum extraction conditions were extraction time of 120 min, extraction temperature of 45℃, and extraction pressure of 35 MPa. By single factor experiment for three repeated experiments, under optimum conditions the Tara oil actual extraction yield was 21.07%, which was consistent with the single factor experiment results. The extracted oil showed transparent and yellowish, belonging to drying oil with high unsaturated fatty acid content, with high quality and valuableuse.
