The invention discloses a method for making Eucommia ulmoides tea with high active substance content. The fresh Eucommia ulmoides leaves are cleaned, branches are removed, fried at low temperature until weightlessness is 10-15%, kneaded for about 20 minutes, then fried at low temperature, sprayed with compound liquid I and compound liquid II to be wet, placed at room temperature for 6-8 hours, then fried at low temperature and packed after drying. The preparation process of Eucommia ulmoides tea omits the steps of withering and fermentation, avoids the degradation of active ingredients in the process of withering and fermentation; the direct low-temperature roasting of fresh leaves of Eucommia ulmoides will inactivate the enzymes in the leaves of Eucommia ulmoides, prevent the degradation of effective ingredients, and replace withering to facilitate the twisting of the leaves of Eucommia ulmoides into strips; the low-temperature roasting can avoid the leaves of Eucommia ulmoides being fried The compound liquid enters into the tissues and cells of Eucommia ulmoides leaves. The invention realizes the low-cost production of Eucommia ulmoides tea with high active substance content, and the brewed tea soup has good taste and no grass green taste.

一种高活性物质含量的杜仲茶制作方法
本专利技术涉及一种高活性物质含量的杜仲茶制作方法,属于制茶
技术介绍
杜仲叶是杜仲科杜仲属植物杜仲(EucommiaulmoidesOliv)的叶子,已于2018年1月国家卫生计生委员会发布的《国家卫生计生委食品司关于就党参等9种物质作为按照传统既是食品又是中药材物质开展试生产征求意见的函》中,将杜仲叶增补为食药物质在湖南省、河南省进行试生产。杜仲叶从食用历史、成分分析、毒理学评价、临床不良反应报道、卫生学检验等相关方面来看,只要按照传统食用习惯,都不会出现安全问题。将杜仲叶制成茶叶是目前最常见的杜仲叶利用方式,但由于杜仲叶中含有绿原酸、桃叶珊瑚苷、京尼平苷、京尼平苷酸、槲皮素和木脂素等多种药用活性成分,在萎凋、发酵、炒青等常规的制茶工艺过程中,虽然可以去除大部分的草青味,但也导致活性成分大量降解,其功能价值大为降低。因此,开发一种既能够去除杜仲叶的草青味,同时又可保持活性成分不被降解,且口感好的杜仲茶是非常有必要的。
技术实现思路
为解决上述现有技术存在的问题,提供一种高活性物质含量的杜仲茶的制作方法,本专利技术制备方法得到的杜仲茶活性物质含量高,无草青味且口感好。为了实现上述专利技术,实施方案如下:将新鲜杜仲叶清洗干净,去枝条,低温(120℃~130℃)炒至失重10~15%,捻揉20分钟左右,再低温(120℃~130℃)炒干,喷洒复合液Ⅰ及复合液Ⅱ湿润,常温放置6~8小时后,再低温(120℃~130℃)炒干后包装即可。所述复合液Ⅰ由果胶酶、纤维素酶液组成,果胶酶和纤维素酶可以降解杜仲叶纤维素,产生寡糖,形成特有 ...
