Abstract

The invention relates to a method for preparing black tea essence by taking black tea as raw material and simultaneously utilizing distillation extraction and biological enzyme zymohydrolysis. The invention also relates to the black tea essence prepared by the method. The essence has the characteristic of the special aroma of keemun black tea, and has obvious effect when being applied to cigarette or tobacco sheet and recombined tobacco leaf.

Description

【Technical field】 [0001] The invention relates to the technical field of black tea essence. More specifically, the present invention relates to a method for preparing black tea essence by using Keemun black tea as raw material by simultaneous distillation extraction and enzymatic hydrolysis. 【Background technique】 [0002] Although there are many studies on the aroma of tea and its extraction methods, most of them focus on volatile components or taste components, and there are relatively few studies on black tea, especially Keemun black tea. There are almost no relevant reports on the invention of preparing black tea essence by combining simultaneous distillation extraction and bio-enzyme enzymatic hydrolysis technology and applying it to tobacco. [0003] Studies have shown that tea leaves contain many of the same aroma components as tobacco. For example, Keemun black tea, as a fermented tea, produces a large amount of ketones, alcohols and aldehydes during the rolling and...
