中文摘要: 基于超声辅助提取法，优化紫大薯花青素提取工艺。通过单因素试验确定盐酸体积分数、超声时间、料液比水平，再结合响应面分析，得到花青素提取最优工艺。结果表明，紫大薯花青素最佳提取工艺条件为料液比1∶22（g/mL）、盐酸体积分数0.63%、超声时间19 min。在此条件下，花青素的提取量为93.62 mg/100 g，比未优化前花青素提取量有明显提升。响应面法优化后的提取工艺提取量较高，相比之前用时更少且更易于批量提取。
Abstract:Anthocyanin extraction was optimized based on an ultrasonic-assisted extraction method.The factor levels of material-to-liquid ratio，hydrochloric acid volume fraction and ultrasonic extraction time were determined via single-factor experiments.Subsequently，Box-Beknhen design-response surface analysis was applied.The results indicated that best extraction method was as follows：material-to-liquid ratio of1 ∶22（g/mL），hydrochloric acid volume fraction of 0.63%，and ultrasonic extraction time of 19 min.Under these conditions，the extracted content of anthocyanins significantly increased to 93.62 mg/100 g when compared to the nonoptimized medium.Furthermore，the optimal extraction condition using the response surface methodology improved the extraction content，consumed less time，and simplified bulk extraction than before.
