    摘要: 冷凍乾燥之海洋微藻 Isochrysis galbaba TK2 以超臨界二氧化碳為溶劑，於溫度 40℃ 與壓力範圍 2000~4000 psia 下，進行油脂萃取實驗。實驗結果顯示油脂於 SC-CO2 中溶解度與萃取率隨著壓力增加而提高，壓力於 3500~4000 psia時萃取率為 9.16~10.01%。比較以超臨界二氧化碳所萃取之油脂與正己烷萃取油脂中之脂肪酸成分，結果顯示飽和脂肪酸成分無顯著性差異，但多元不飽和脂肪酸成分有稍微差異。超臨界二氧化碳萃取之油脂顏色呈現黃綠色，且較正己烷萃取油脂亮度高。
    Freeze-dried samples of marine microalga Isochrysis galbana TK2 were subjected to supercritical CO2 at a temperature of 40℃ and pressure between 2000 and 4000 psi. Results showed that the solubility and extracted yields of the lipids increased with the pressure. The extracted yields of the lipids were 9.16-10.01% when the pressure was between 3500 and 4000 psia. The saturated fatty acid composition of supercritical CO2 extracted lipid was not significantly different in the case of n-hexane extracted oil; however, the polyunsaturated fatty acid composition was significantly different between the extracted lipids. The color of the supercritical CO2 extracted oil was yellow-oreen and was brighter than the color of the n-hexane extracted oil.
