中文摘要: 为探究花生红衣中原花青素的提取效果,在超声辅助提取的基础上,结合水浴浸提以提高提取效果,并利用正交试验对工艺进行优化。结果表明,各因素影响原花青素提取效果的主次顺序为:超声时间>乙醇体积分数>料液比>超声温度;提取最佳条件为:超声时间15 min、乙醇体积分数60%、料液比1∶45(g/mL)、超声温度35℃、水浴温度50℃、水浴时间50 min,在此条件下原花青素提取率为9.07%。
Abstract:In order to optimize the extraction process of anthocyanidins from peanut skin,ultrasonic-assisted extraction,combined with water-bath extraction,was performed,and orthogonal tests were used to improve the process.The results revealed the following as primary factors influencing the extraction of procyanidins:ultrasonication time>ethanol volume fraction>solid-liquid ratio>ultrasonication temperature.The optimal extraction conditions were as follows:ultrasonication time 15 min,ethanol volume fraction 60%,solid-liquid ratio 1∶45(g/mL),ultrasonication temperature 35℃,water-bath temperature 50℃,and water-bath incubation time 50 min.Under these conditions,the extraction rate of procyanidins was 9.07%.
