Abstract:	本研究中使用超臨界二氧化碳從佛手柑中進行精油的萃取，實驗以固定流量和萃取時間，然後再藉由改變壓力、溫度兩變化因子去研究對於精油產率之影響。每組實驗條件因子皆有三種水準。在實驗過程中，實驗設計的壓力條件設定為2400psi、3100psi、3800psi，溫度條件為40℃、50℃、60℃。在研究上為了取得萃取結果的再現性，每組實驗條件都會重複三次，共有實驗27組試驗。並且對實驗結果進行雙因子變異數分析以及二階迴歸分析，探討佛手柑精油產率在各因子與因子間交互作用下的顯著性，並使用Excel及MATLAB軟體製作迴歸線圖後再對二階模型進行分析得到本實驗範圍中之最適操作條件。最後再利用索式萃取法萃取佛手柑粗脂肪精油，對比與超臨界萃取法所得到實驗結果之產率是否相同。並使用氣相層析質譜儀分析兩種萃取法得到的精油成分是否一致。 The objective of this study is to do the extraction oil from bergamot using supercritical CO2. This experiment investigates the effect of essential oil yield by changing the two factors of pressure and temperature under constant flow and extraction time. The pressure conditions of the experimental design are set to 2400psi、3100psi、3800psi , and the temperature conditions are 40℃、50℃、60℃. In order to obtain the reproducibility of extraction results, each set of experimental conditions was repeated three times for a total of 27 sets of experiments. To explore the significance of the yield of bergamot essential oil under the interaction of factors, two-factor variance and second-order regression analysis were performed on the experimental results. After using Excel and MATLAB to make regression line graph, it was analyzed to obtain the optimum operating conditions within the scope of this experiment. At last, compare the yields of crude bergamot essential oils obtained by Soxhlet extraction and supercritical extraction method, and make use of gas chromatograph-mass spectrometer to analyze whether the essential oil components obtained by the two extraction methods are consistent.
