中文摘要: 为了开发出一款功能型袋泡茶,采用单因素试验和响应面法优化袋泡茶配方:以干桑叶、干淮山片作为原料, 经过打粉、过筛、装袋、冲泡后,以感官评定和体外降糖抑制率作为评价指标,分别探讨了桑叶产地、每包净重、桑叶粒度 和桑淮质量比对桑淮袋泡茶的的影响;在感官评定优秀的基础上,再通过 Box-Behnken 响应面法优化分析每包净重、桑 叶粒度和桑淮质量比对桑淮袋泡茶体外降糖抑制率的影响。结果表明:用广东产地的干桑叶,每包净重 4.14 g,桑叶粒度 为 18 目,桑淮质量比 5 ∶ 1 确定为桑淮袋泡茶的研制配方。

Abstract:In order to develop a functional teabag tea, single factor experiments and response surface method- ology were used to optimize the teabag recipe:the dry mulberry leaves and dried yam slices were used as raw materials. After the powder, sieving, bagging and brewing, sensory evaluation and in vitro hypoglycemic inhibi- tion rate were used as evaluation indexes. The effects of mulberry leaf origin, net weight per pack, mulberry leaf grain size and mulberry and yam quality ratio on mulberry-yam tea were discussed respectively.Then, based on the excellent method of sensory evaluation, the effects of net weight per bag, mulberry leaf size and mulberry quality on the hypoglycemia inhibition rate of mulberry-yam tea were analyzed by Box-Behnken response sur- face method.The results showed that the dry mulberry leaves in Guangdong were 4.14 g per bag, and the grain size of mulberry leaves was 18 mesh. The quality ratio of mulberry leaves and yam was 5 ∶ 1.
