摘　　要：以酿酒后的葡萄渣粕为原料,采用微波辅助对渣粕中的花青素进行提取,考查了微波辅助提取花青素的最佳工艺条件,采用紫外分析方法对花青素的含量进行测定。研究表明,微波法提取花青素的最佳工艺条件为以1.5 mol/L HCl-95%乙醇(15∶85)为溶剂,料液比1∶30,提取温度50℃,微波功率500 W,提取时间8 min,花青素提取量为433.14 mg/100 g。Microwave-assisted extraction of anthocyanins from grape dregs and meal after winemaking was carried out.The optimum conditions of microwave-assisted extraction were investigated.The content of anthocyanins was determined by UV analysis.The results showed that the optimum extraction conditions were as follows:1.5 mol/L HCl-95%ethanol(15∶85)as solvent,solid-liquid ratio 1∶30,extraction temperature 50℃,microwave power 500 W,extraction time 8 min,the extraction rate of anthocyanin was 433.14 mg/100 g.
