中文摘要 | 使用酸化乙醇萃取法成功地從'TNG 73'紫甘藷中萃取出花青素,三個萃取參數包括HCl濃度、萃取時間、以及萃取溫度都在本研究中被仔細評估,反應曲面法(Response surface methodology, RSM)是一種很有效的統計工具,可用來建立廻歸模組,而此廻歸模組的係數經計算後,可用來預測萃取製程的表現及決定最佳的萃取操作條件,本研究結果顯示,12% HCl(1.5 N HCl和乙醇的混合物)、45分鐘萃取時間、以及50°C萃取溫度是'TNG 73'紫甘藷花青素的最佳萃取條件。 |
英文摘要 | Anthocyanins were successfully extracted from 'TNG 73' purple sweet potato roots by using acidic-ethanol extraction. Three extraction parameters including HCl concentration, extraction time, and temperature were evaluated. Response surface methodology (RSM), an effective statistical technique was applied to establish a regression model. The coefficients of the regression model were calculated and used to predict the extraction performance and determine the optimal operating conditions. In conclusion, the optimal conditions for the 'TNG 73' anthocyanin extraction were determined to be 12% HCl (1.5 N HCl in EtOH), 45 min, and 50℃. |
