Production method of Tieguanyin tea leaves high in amino acid content

Abstract

The present invention discloses a production method of Tieguanyin tea leaves high in amino acid content. The production method comprises the following steps: cystine, tyrosine, aspartic acids, valine, alanine, glycine, proline, arginine and lysine are mixed evenly, and the mixture is added into water to be mixed evenly to obtain material A; and fresh Tieguanyin leaves are weighed, the material A is sprayed on the Tieguanyin leaves, the Tieguanyin leaves are air-spread, the air-spread Tieguanyin leaves are placed under gentle sunlight at 4-5 pm for 30-50 min, protease and cellulose are added, the treated Tieguanyin leaves are subjected to rocking and cooling alternately, the rocked and cooled Tieguanyin leaves are rolled, the material A is sprayed on the rolled Tieguanyin leaves, the treated Tieguanyin leaves are put into a sealed fermentation tank to conduct fermentation until 75-80% of the materials turn red, the fermented materials are air-spread to a room temperature, then the air-spread materials are sent into a green tea roasting machine to conduct enzyme deactivating, the remaining material A is added into the enzyme deactivated materials to be mixed evenly, the treated materials are dried to the moisture content of 5-8wt%, the dried materials are baked, and the baked materials are cooled to a room temperature to obtain the Tieguanyin tea leaves. The Tieguanyin tea leaves are high in amino acid content, unique in taste, simple in technology, and low in costs.

Description

technical field [0001] The invention relates to the technical field of Tieguanyin tea, in particular to a production method of Tieguanyin tea with high amino acid content. Background technique [0002] Tieguanyin is a kind of oolong tea and one of the top ten famous teas in China. It is between green tea and black tea. At present, the production enterprises and the consumer market have higher and higher requirements for tea, and there is an urgent need to develop a series of unique raw materials to meet Due to the growing consumer demand, many Luzhou-flavored Tieguanyin teas sold on the market are not qualified in the production process, the synthesis of tea caffeine and tea polyphenols is significantly increased, and the content of amino acids is reduced. , there are also some high-quality Tieguanyin teas on the market, but due to the influence of the production method, the taste is relatively single. How to prepare a kind of Tieguanyin tea with high amino acid content and ...
