Problems solved by technology

However, during the soaking process, Tieguanyin often produces a bitter taste or slow sweetness, which leads to a decline in the grade of tea during the evaluation and grading process. Therefore, effectively improving the taste of Tieguanyin tea soup is extremely important for improving the quality of Tieguanyin.

Abstract

The invention provides a processing method for sweet Tie Guanyin tea. According to the processing method, cellulase liquids with different concentrations are spayed between a cooling step and a rocking step in the conventional production process of the Tie Guanyin tea. The processing method comprises the following specific steps: carrying out primary cooling on the sunned tea, spraying the cellulase liquids on the primarily cooled tea and then carrying out primary rocking; after the primary rocking is ended, carrying out secondary cooling, spraying the cellulase liquids on the secondarily cooled tea and then carrying out secondary rocking; after the secondary rocking is ended, carrying out cooling for the third time, spraying the cellulase liquids on the cooled tea for the third time and then carrying out rocking for the third time; after the rocking for the third time is ended, carrying out cooling for the fourth time. Compared with the tea not treated by the cellulase liquids, the Tie Guanyin tea produced by the processing method provided by the invention has the advantages of smoother mouthfeel, sweeter taste and higher sweet aftertaste speed; the quality of the Tie Guanyin tea is effectively improved; economic benefits of the tea are increased.

Description

technical field [0001] The invention belongs to the field of oolong tea processing, and in particular relates to a processing method for sweet and clear Tieguanyin tea. Background technique [0002] Tieguanyin belongs to the oolong tea category and is one of the six major tea categories in China. In recent years, Tieguanyin has been recognized by consumers for its unique aroma and taste. However, during the soaking process, Tieguanyin often produces a bitter taste or slow sweetness, which leads to a decline in the grade of tea during the evaluation and grading process. Therefore, effectively improving the taste of Tieguanyin tea soup is extremely important for improving the quality of Tieguanyin. Cellulase is a kind of highly active biocatalyst. Adding cellulase liquid during tea processing, especially during fermentation and oxidation, can effectively improve the sugar content and other extract content of the prepared tea. Therefore, the present invention uses the effect o...
