摘　　要：采用天然多穗石柯甜茶为原料,以功效成分含量作为考察指标,通过单因素试验和响应曲面试验,对甜茶的功效成分含量的提取工艺条件进行了优化,并在此基础上开展甜茶速溶茶粉的制备研究。结果表明:在料液比为1∶43.01 (g/mL),浸提温度为92.67℃,浸提时间为50.76 min时,甜茶水提液的功效成分含量最优,根皮苷为7.15%,三叶苷为33.11%,总量为40.26%,在此基础上制得的甜茶速溶茶根皮苷、三叶苷2种功效成分含量分别为17.42%和40.89%,总量为58.31%,速溶茶粉得率保持在12%以上,且感官评价、理化指标较理想。此研究优化了多穗石柯甜茶功效成分的提取工艺,且在此基础上开发的甜茶速溶茶功效成分含量高,该研究为甜茶综合利用及产品研发提供理论参考和技术支持。The extraction process conditions of natural Lithocarpus polystachyus sweet tea were optimized by single factor test and response surface methodology,and the preparation of instant sweet tea powder was studied.The results showed that when the ratio of solid to liquid was 1:43.01(g/mL),the extraction temperature was 92.67℃,and the extraction time was 50.76 min,the content of effective components in the sweet tea extract was the best,with phloridzin being 7.15%,trefoil being 33.11%,and the total amount being 40.26%.On this basis,the content of two effective components in the instant sweet tea was 17.42%and 40.89%,and the total amount was 58.31%.The yield of instant tea powder remained above 12%,and the sensory evaluation and physical and chemical indexes were ideal.In this study,the extraction process of the effective components of the sweet tea of Lithocarpus polystachyus was optimized,and the content of the effective components in the instant sweet tea developed on this basis was high,which provided theoretical reference and technical support for the comprehensive utilization of sweet tea and product development.
