Research of fermented Sedum kamtschaticum tea beverage

以干燥的养心草为原料,开发养心草发酵茶饮料。通过单因素试验和正交试验确定最佳工艺参数。结果表明,养心草发酵茶饮料最佳工艺条件为料液比1∶150(g∶mL)、白砂糖添加量5%、冲茶水温度70℃、发酵时间2 d,在此工艺条件下,养心草发酵茶饮料具有养心草天然的茶香味、呈淡黄色、口感浓郁,感官评分为98.9分。

Fermented Sedum kamtschaticum tea beverage was developed using dry S. kamtschaticum as raw material. The optimum technological conditions were determined by single factor experiments and orthogonal experiments. The results indicated that the optimum technological conditions were as follows： solid-liquid ratio 1：150 （g：ml）, sugar content 5%, water temperature 70 ℃, fermentation time 2 d. Under these conditions, S. kamtschaticum fermentation tea beverage had natural tea flavor of S. kamtschaticum, with light yellow color, pleasant taste. The sensory score of the beverage was 98.9.
