摘要
[目的]确定酒糟类黑精最佳超声提取工艺参数.[方法]以酒糟为原料,采用单因素试验、Plackett-Burman设计、最陡爬坡试验及Box-Behnken设计进行超声辅助酒糟类黑精提取工艺研究.[结果]试验确定酒糟中类黑精的最佳条件为超声时间23 min、超声温度55 ℃、pH 1.0、料液比1∶29(mg∶mL)、超声功率540 W、颗粒直径270 μm,该条件下酒糟中类黑精的提取率为66.92%.[结论]该研究可为类黑精的开发应用提供参考.
Abstract
[Objective] The ultrasonic-assisted extraction technology of melanoidin from vinasse was optimized.[Method] With vinasse as raw material, single factor test, Plackett-Burman design(PB), the steepest ascent method and Box-Behnken design (BB) was used to establish the optimal processing.[Result]The optimal conditions were as followed: ultrasonic treatment of 23 min, ultrasonic treatment temperature 55 ℃, pH 1.0, ratio of material and liquor 1∶29(mg∶mL), ultrasound power 540 W and particle diameter 270 μm.The extraction rate is 66.92%.[Conclusion] The study can lay a foundation for development and application of melanoidin.
