摘要
红茶和蜂蜜具有十分丰富的资源且营养丰富,本课题以红茶为主蜂蜜为辅,对红茶饮料的工艺参数和流程加以确认,研究蜂蜜红茶饮料的生产工艺,然后制出该饮料,该红茶饮品滋味酸甜,口味香醇。
对不同浸提条件下红茶饮料的香气、色泽和吸光度进行对比研究,得知浸提温度、时间、水茶的质量比及添加剂等因素对蜂蜜红茶饮料制备存在很大影响。本试验研究了不同澄清剂种类对蜂蜜红茶饮料稳定性的影响。最后表明,十分钟的浸提时间,2%的浸提茶水比,浸提温度选为90℃时最佳,,再配以2%的复合澄清剂Ⅱ效果更佳。
关键词:蜂蜜红茶饮料工艺
Abstract
There are certain ponents in honey and black tea,and their resources are very researches were conducted on the manufacturing technique of black tea beverage mixed with technological parameters and production process were determined so as to develop mellow and savoury black tea beverage with rich nutrition.
parison of the fragrance,color and absorptivity obtained under different extracting conditions,it could be discovered that extracting time,temperature,concentration pound clarifying agents had important influence on the preparation of black tea beverage mixed with another focus of the paper was the influence of various clarifying agents on the stability of the results demonstrated that the conditions for optimal extraction conditions were:extraction time 10 min,water to tea ratio 50,extraction temperature 90℃,pH value of the liquid about ,and 2% of posite clarifying agents II used in the study.
Keywords: Honey Black Tea Beverage Technique
