Active oolong tea

Abstract

The present invention is mechanical active oolong tea producing process and the active oolong tea product has high bioavailability, less pesticide residue and high quality. The mechanical active oolong tea producing process includes the successive steps of: mixing fresh tea with acetic acid solution, catalysis, heat treatment, cold treatment, no pressure kneading, kneading in kneading machine to form 5-10 turns, deactivating enzyme, cold wind treatment, kneading to form strip, frying, rounding, packing, etc.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a production method of active oolong tea. Background technique [0002] Active oolong tea is a semi-fermented tea between non-fermented tea (green tea) and fully fermented tea (black tea). After brewing, the leaves of oolong tea will have red stripes, the soup color will be green and yellow, and it will have a natural floral fragrance. When the existing oolong tea is drunk, the active ingredients are incompletely decomposed, the bioavailability is not high, and the pesticide residues in the tea leaves cannot be degraded; Mainly, the labor intensity is high, and the degree of production standardization is difficult to grasp, which is not conducive to the improvement of oolong tea product quality and standardized production. Contents of the invention [0003] The purpose of the present invention is to aim at the existing oolong tea when drinking, the active ingredient is ...

Problems solved by technology

[0003] The purpose of the present invention is to aim at the existing oolong tea when drinking, the active ingredient is not completely decomposed, the bioavailability is not high, the pesticide residue in the tea leaves is difficult to degrade, and the process of oolong tea before greening is mainly manual, with high labor intensity, The deficiency of low standardization degree of production provides a kind of active oolong tea production method mainly based on machinery, low labor intensity, high standardization degree of production and conducive to the improvement of oolong tea product quality and standardized production. The active oolong tea produced by this production method Oolong tea has higher quality and more fragrant aroma, which makes β, γ-heptenol, and α, β-heptenol, α- and β-ionone aroma components more effectively catalyzed and exerted, and has high bioavailability and can fully Utilize the active ingredients in tea, especially the plant protein in tea that can be cracked into small molecular active proteins, which is beneficial to the combined use of human cells and can degrade the pesticide residues in tea
