Abstract

The invention discloses a black tea production process which comprises the working procedures of fresh leaf grading, withering, rolling, deblocking, straightening through throwing, fermentation, baking, primary aroma raising, storage, cellaring fermentation, secondary aroma raising, and the like. Through the implementation of the black tea production process disclosed by the invention, the full fermentation of the black tea is ensured, and the aroma raising is implemented adequately, so that the black tea is more full-bodied and purer, and the quality of the black tea is improved.

Description

Technical field [0001] The present invention involves a black tea production process, mainly a black tea production technology that is fermented and secondary fragrance. Background technique [0002] Black tea is a fermented tea. It is based on the sprouts and leaves of tea trees. It is refined by typical processes such as withering, twisting (cut), fermentation, and drying.Because of its dry tea and brewed tea soup, it is based on red, so it is called black tea.Black tea occurred in the process of processing with tea polyphenol enzyme -pronounced chemical reactions. The chemical composition in fresh leaves changed greaterly, and tea polyphenols were reduced by more than 90%, producing new ingredients such as tea lutein and tea erytheine.EssenceThe aroma is significantly increased than fresh leaves.So black tea has the characteristics of black tea, red soup, red leaves and sweet mellow.The current black tea production process usually includes: (1) withering: spreading fresh leave...
