Response Surface Analysis of the Optimization of Ultra High Pressure Extraction of Ginger Essential Oil

摘要：

Previous published experimental results of fractional factorial experiments showd that significant external factors affecting extract of essential oil from the ginger by ultra high pressure extraction (UHPE) are pressure , extraction time, the ratio of solid to liquid. Based on these results, response surface methodology (RSM) has been employed in the present work, and a quadratic equation for UHPE is built with RSM. By analyzing response surface plots and their corresponding contour plots and by solving the quadratic equation, experimental values are shown to be significantly in good agreement with predicted values.The optimal extraction conditions are as following: pressure 300MPa, extraction time3.6min , ratio of solid to liquid 1:15 (g:mL).The maximum extraction has been carried out as the optimum condition and extraction yield is obtained as 3.29%.
