Description
Technical field
The present invention relates to tea making field, particularly the processing technology of a kind of Radix Glycyrrhizae black tea.
Background technology
Black tea, with the new tea bud-leaf of suitable for making this product for raw material, through the tune that withers, kneads, ferments, dries etc. that typical process process is refining to be formed. Because of its dry dark brown pool with the millet paste brewed with redness for homophony, therefore named black tea. Black tea there occurs the chemical reaction centered by tea polyphenols enzymatic oxidation in the course of processing, and the chemical composition change in fresh leaf is relatively big, and tea polyphenols reduces more than 90%, creates the composition that theaflavin, thearubigins etc. are new. Aroma substance kind more than 50 from fresh leaf, increases to kind more than 300, a part of caffeine. Catechin becomes the complex that flavour is delicious with theaflavin complexation, thus defining the qualitative characteristics of black tea, red soup, red autumnal leaves and fragrant and sweet taste alcohol.
Radix Glycyrrhizae, have another name called that state is old, Herba Hedyotis cantonensis, Glycyrrhiza uralensis Fisch., sweet root. Radix Glycyrrhizae is recorded in " pearl sac " to be had: " enriching blood, nourishing the stomach " effect. Cure mainly the effects such as heat-clearing and toxic substances removing, expelling phlegm for arresting cough, gastral cavity abdomen. At present the nutritional labeling of Radix Glycyrrhizae is applied to the report in black tea and few.
