中文摘要 | 本試驗以超臨界二氧化碳為溶劑,乙醇為助萃劑、探討從豬肝、肺、脾 藏萃取游離胺基酸。豬肝以添加40%乙醇為助萃劑、萃取時間2小時;豬肺以添 加30%乙醇為助萃劑、萃取時間3小時;豬脾以添加30%乙醇為助萃劑、萃取時 間3小時可得最佳之游離胺基酸萃取效果。游離胺基酸萃出量以脾臟為最高。利 用3300psi壓力之超臨界二氧化碳併用乙醇助萃劑萃取豬內臟,比利用4300 psi壓 力具有較高之游離胺基酸萃取率。 |
英文摘要 | This experiment was conducted to extract amino acids from pork liver, lung and spleen using supercritical CO �� combined with ethanol as an entrainer. We found that using supercritical CO �� combined with 40% ethanol as an entrainer for 2 hours could extract most of the free amino acids from pork liver. When combined with 30% ethanol as an entrainer for 3 hours most free amino acids could be extracted from pork lung and pork spleen. The extraction rate of pork spleen was the highest. Comparing extraction pressure of 3300 psi with 4300 psi, the extraction pressure of 3300 psi could extract more free amino acids from pig viscera. |
