摘要：The purpose of this study was to evaluate the influence of high hydrostatic pressure assisted extraction (HHPE) on the anthocyanins from blueberry ( Vaccinium ashei) pomace. From the Plackett-Burman Experimental Design (PBD) only the liquid-solid ratio, ethanol concentration, and extraction pressure were found to significantly affect the extraction yield of anthocyanin content. Hence, the outcome of Box-Behnken Design suggested that the optimal operating conditions of the HHPE for the yield of anthocyanin content were liquid-solid ratio 41 ml/g, ethanol concentration 63%, and extraction pressure 443 MPa. At these conditions, 107.9 mg/100 g anthocyanins was obtained, which was more than by the control extraction (67.63 mg/100 g). 10 anthocyanins were identified by HPLC-ESI-MS, malvidin-3-galactoside and malvidin-3-glucoside were the major anthocyanins.
