| 摘 要： | 为了比较超临界萃取姜油树脂与溶剂浸提法的差异,本文分别采用了丙酮、乙醇和超临界二氧化碳等方法,主要指标为萃取率和姜辣素含量,结果显示:乙醇法萃取率为7.5167%,超临界法和丙酮法比乙醇法萃取率低,二者之间无显著性差异;超临界二氧化碳法姜辣素得率为0.7155%,显著高于乙醇法和丙酮法。因此若从萃取率出发,应考虑采用乙醇法,若从姜辣素含量来考虑,应采用超临界二氧化碳法。

| Abstract: | Ginger flavor was extracted from ginger powder respectively with supercritical carbon dioxide fluid, ethanol and acetone in this study. The results showed that: ethanol can acquire an extraction rate of 7.5167%, which is higher than the other two methods distinctively. However, when comparing the gingerol content, the method of supercritical carbon dioxide fluid yield reaches to 0.7155%, higher than the other two methods evidently. |
