Problems solved by technology

However, its fragrance is limited by the variety of tea itself, which cannot meet the diverse needs.
The fragrance of bamboo leaves belongs to the popular "fresh fragrance type" nowadays. The aromatic components are mainly aldehydes, furans, and ketones. The volatile components of bamboo leaves have the fragrance of green leaves. They are widely used in food additives, cosmetics and air fresheners. All have extensive application, have not yet seen the black tea making process that the fragrance of bamboo leaf is applied to black tea

Abstract

The invention discloses a natural bamboo-flavored black tea production process. The natural bamboo-flavored black tea production process comprises the following steps: fresh leaf picking; withering; rolling by the three-step method; primary fermentation; primary drying, secondary fermentation; secondary drying; mixing of tea leaves and bamboo leaves for 5-6 h by performing repeated multi-layer stacking in a closed chamber according to the weight ratio (the bamboo leaves to the tea leaves) of (1-2):6 in such a way that the tea leaves and the bamboo leaves are placed layer by layer; fumigation in a bamboo tube in such a way that the tea leaves are placed in the bamboo tube, the cover is closed, the bamboo tube is placed in a steam tank, fumigated for 9-12 min at 100-105 DEG C, and naturally cooled down, and then tea is poured out; third-time fermentation; third-time drying. After a black tea produced by the method is brewed, the tea soup is red and bright, has a fresh and strong bamboo flavor and a long aftertaste, and tastes sweet and refreshing but not bitter.

Description

Technical field [0001] The invention relates to the field of tea making, in particular to a process for making natural bamboo-flavored black tea. Background technique [0002] Black tea is a fully fermented tea. During the processing of black tea, a chemical reaction centered on the oxidation of tea polyphenols has occurred. The chemical components in fresh leaves have changed greatly. The tea polyphenols are reduced by more than 90%, resulting in theaflavins, Thearubin and other new ingredients. The aroma substances are significantly increased compared to fresh leaves, so black tea has the characteristics of black tea, red soup, red leaves, and sweetness. However, its fragrance is limited by the variety of tea itself and cannot meet the diverse needs. The fragrance of bamboo leaves belongs to the popular "fresh fragrance". The main aromatic components are aldehydes, furans, and ketones. The volatile components of bamboo leaves have the fragrance of green leaves. It is used in ...
