摘要
为高效获得花青素,采用离子液体-微波辅助提取黑豆皮中的花青素,考察提取时间、提取温度、微波功率、离子液体浓度、料液比对提取量的影响,采用响应曲面法对提取工艺进行优化。结果表明,最佳提取条件为提取时间45min,离子液体浓度0.7 mol/L,料液比1∶30(g/mL),微波功率460 W,提取温度49℃。在此条件下,花青素的提取量为4.834 mg/g,预测值和实际测定值接近,可以为黑豆皮花青素后续的利用和研发提供参考。
In order to obtain anthocyanin efficiently,the extraction of black soybean coats anthocyanin by ionic liquid ultrasound was studied. The effects of extraction time,temperature,microwave power,ionic liquid concentration and solid-liquid ratio on the extraction amount were investigated. The extraction process was optimized by response surface methodology. The results showed that the optimum extraction conditions were as follows:extraction time 45 min,ionic liquid concentration 0.7 mol/L,solid-liquid ratio 1 ∶ 30(g/mL),microwave power 460 W,extraction temperature 49 ℃. Under these conditions,the yield of anthocyanin from black soybean coats was 4.834 mg/g,and the predicted value is close to the actual measured value,which can provide a basis for the comprehensive development and follow-up research of anthocyanin from black soybean coats.
