中文摘要: 以蓝莓加工废弃物果渣为原料,优化蓝莓花青素提取工艺。试验结果表明,最佳提取条件为超声功率200 W(超声提取 2 s,间歇 4 s)、提取温度 30 ℃、提取时间 20 min、乙醇体积分数 70%(pH 2.5)、料液比 1∶30(g/mL),花青素提取率达9.99 mg/g。采用高效液相色谱对花青素粗提物进行成分分析,得到5 种蓝莓花青素,即锦葵色素(36.26%)、飞燕草色素(24.08%)、矢车菊色素(22.08%)矮牵牛色素(12.53%)和芍药色素(5.05%)。

Abstract:The best ultrasonic extraction conditions of anthocyanins from blueberry processing wastes were optimized.The optimal conditions were as follows:ultrasonic power,200 W,2 s,4 s;extraction temperature 30 ℃;extraction time 20 min;ethanol volume fraction 70 %(pH 2.5);and material-to-liquid ratio 1∶30 (g/mL).The maximum yield of anthocyanins was 9.99 mg/g.The composition of anthocyanins was identified by high performance liquid chromatography (HPLC),five anthocyanins were identified in blueberry pomace extracts,namely,malvidin (36.26 %),delphinidin (24.08 %),cyanidin (22.08 %),petunidin(12.53%)and peonidin(5.05%).
