摘要: 以发酵后葡萄籽为原料,研究微波、纤维素酶和超声波辅助提取葡萄籽中原花青素的工艺条件,对影响原花青素提取率的因素进行考察,通过正交试验确定葡萄籽中原花青素的最佳提取工艺。结果表明最佳方法为微波辅助提取,其最佳工艺条件:料液比1:25(g/mL)、乙醇体积分数80%、微波时间40s、微波功率115W,原花青素的提取率为10.70%。

Abstract: The aim of this study was to optimize technical conditions for ultrasonic-assisted ethanol extraction, cellulase hydrolysis-based extraction and microwave-assisted ethanol extraction of proanthocyanidins from grape seed power using one-factor-at-a-time coupled with orthogonal array design method. Microwave-assisted extraction was found to be the best of the three methods, and the optimal process conditions were ethanol concentration of 80%, material-to-liquid ratio of 1:25 (g/mL), microwave treatment time of 40 s and microwave power of 115 W. Under these conditions, the extraction rate of proanthocyanidins was 10.70%.
