摘要:

以蒜素提取率为指标,通过正交试验对超临界CO2 萃取蒜素的萃取条件进行优化,得到最佳工艺参数:萃取压力15MPa、萃取温度40℃、静态浸提时间30min,动态萃取时间105min,在此条件下提取率可达76.70%。与传统的溶剂提取法和超声波辅助提取法相比,超临界CO2 萃取法提取率更高,传统的溶剂提取法和超声波辅助提取法提取率分别为63.16% 和68.12%。

Abstract:

We optimized the supercritical CO2 extraction of allcin from garlic cloves to obtain the highest extraction yield by single-factor and orthogonal array methods. The optimal conditions for the improved supercritical CO2 extraction of allicin were determined as follows: extraction press 15 MPa, extraction temperature 40 ℃, static extraction time 30 min and dynamic extraction time 105 min. Under these conditions, the extraction yield could reach 76.70%, which was higher than 63.16% by traditional solvent extraction and 68.12% by ultrasonic-assisted extraction.
