| Abstract: | Anthocyanins in mulberry wine lees was extracted with ethanol with HC1. In order to maximize the extraction of anthocyanins, single factor experiment design combined with response surface was employed. The optimum extraction conditions were as follows： extraction temperature 80℃, extraction time 150.3min and solid-to-liquid ratio 1：20. Under these conditions, the yield of anthocyanins was 1.89mg/g, which was 98.5% of the theoretically predicted value of 1.92mg/g. |
