Abstract

The invention discloses camellia sinensis var.assamica and a preparation process thereof. The preparation process comprises the following steps: preparing aspergillus niger, aspergillus foetidus, aspergillus japonicus var. japonicas, penicillium and saccharomycetes into a bacterial suspension; placing compound amino acid, glucose, mannitol and inulin into the bacterial suspension to obtain a mixedsolution; mixing the mixed solution with Yunnan large-leaf sun-dried green raw tea proportionally; and then carrying out pile fermentation and air drying to obtain the camellia sinensis var.assamica.According to the process disclosed by the invention, the sun-dried green raw tea is inoculated with a specific strain so that growth and development of a fermentation dominant strain can be rapidly improved and a whole fermentation process is accelerated; furthermore, the compound amino acid, the glucose, the mannitol and the inulin are added into the bacterial suspension so that nutrient substances can be provided for the strain and proliferation of a dominant bacterial flora is promoted; meanwhile, water balance can be maintained and the activity of fermenting and producing enzymes of the strain is improved; and a better fermentation effect is achieved and the quality of the prepared camellia sinensis var.assamica is improved.

Description

technical field [0001] The invention relates to the technical field of tea, in particular to a Pu'er tea and a preparation process thereof. Background technique [0002] Pu'er tea (scientific name: Camellia sinensis var.assamica) is mainly produced in Xishuangbanna, Lincang, Pu'er and other areas in Yunnan Province; Pu'er tea pays attention to brewing skills and drinking art, and its drinking methods are rich. Mixed drink; Pu'er tea soup has strong orange-yellow color, sharp and long-lasting aroma, unique fragrance type, rich and mellow taste, and is durable for brewing. [0003] At present, the traditional Pu-erh tea production process mainly includes adding water, stacking, fermenting, and turning the raw green tea. The fermentation time is generally about 40 to 60 days, and then air-dried and aged to obtain Pu-erh tea; The production process of tea has a long fermentation time, and the quality of the prepared product cannot be guaranteed, resulting in the loss of tea lea...
