AI Technical Summary

Technical Problem

In the traditional fermentation process of Pu'er tea, the composition of the microbial community is uncontrollable, and the level and synchronicity of enzyme activity are difficult to predict, resulting in unstable tea soup color and aroma quality, low production efficiency, and the inability of a single strain or enzyme preparation to simultaneously enhance the activity of two types of enzymes, and they are easily deactivated at high temperatures.

Method used

A strain of *Branchiaceae* LicG6 was used, which can simultaneously secrete β-glucosidase and polyphenol oxidase. Through staged temperature-controlled fermentation, the synergistic transformation of aroma and color in tea was achieved, including the release of floral aroma and the change of liquor color.

Benefits of technology

The same fermentation process brings out the floral aroma characteristics of the tea leaves and changes the color of the tea soup from orange-yellow to orange-red, improving the aroma richness and clarity of the tea soup, shortening the fermentation cycle, and increasing production efficiency.

Abstract

The application discloses a strain of Lecythophora ramosa LicG6 and application of the strain in solid-state fermentation of Pu'er tea, and belongs to the field of industrial microbial resource development and tea deep processing technology. The Lecythophora ramosa LicG6 is preserved in the China General Microbiological Culture Collection Center on June 14, 2024, and the address is No. 1, Xibei Road, Chaoyang District, Beijing, and the preservation number is CGMCC No. 41370. The application inoculates the Lecythophora ramosa LicG6 strain with double-enzyme synchronous secretion capacity, namely, simultaneously high expression of beta-glucosidase and polyphenol oxidase, into a solid-state fermentation system of Pu'er tea, realizes flower fragrance development by continuously hydrolyzing and releasing glycoside aroma precursor driven by beta-glucosidase under the condition of temperature control in stages, realizes red soup color transformation by oxidizing and polymerizing catechin driven by polyphenol oxidase, and thus, the two quality targets of "flavor enhancement" and "color transformation" are achieved simultaneously in the same fermentation process.
