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.

Key words: ginger, supercritical fluid extraction(SFE), ginger oleoresins, gingerol
