Production method for improving quality of Liupu tea

Abstract

The invention relates to application of eurotium cristatum in the production of Liupu tea, which belongs to the crossing field of food engineering and biotechnology. The production method for the Liupu tea is an improvement on the prior Liupu tea production flow through biotechnology, namely after primary distillation, a bacterial suspension containing eurotium cristatum spores is used for spray inoculation, and after redistillation, tea strains are crushed into pieces for inoculation again. Thus, when the Liupu tea is in composting fermentation, the eurotium cristatum can quickly become predominant bacteria to inhibit the growth of other bacteria, and when the Liupu tea is in ageing, golden flowers grow out frondently and universally so as to improve the quality of the Liupu tea. The application of the eurotium cristatum improves the quality of the Liupu tea, and solves the problems that in the prior art, the quality is unstable, the ageing time is long, the growing golden flowers are difficult to control and are easy to pollute and the like. Simultaneously, the invention discloses a method for simply and easily obtaining and expanding the cultivation of eurotium cristatum strains.

Description

Technical field: [0001] The invention relates to the application of Saccharomyces coronoidis in the production of Liubao tea, which belongs to the cross field of food engineering and biotechnology. Background technique: [0002] Liubao tea is the most famous black tea in Guangxi, well-known at home and abroad, and is a traditional export product of Guangxi. [0003] The existing production process of Liubao tea: the initial production process is greening → kneading → stacking → re-kneading → drying; the replication process is sieving and shaping → picking stems and slices → blending → initial steaming → stacking fermentation → drying → Re-steaming → basket pressing (or cake making) → aging → packaging the finished product. [0004] The production of Liubao tea has to go through a unique "aging" process. The main purpose is to produce "golden flowers". The semi-finished products of Liubao tea pressed in baskets (or pressed cakes) are placed in an aging cave with a certain te...

Problems solved by technology

The current measure to overcome the difficulty of producing "golden flowers" is to put the pressed tea leaves (or pressed cakes) into the aging caves where Liubao tea is stored all the year round, because most of the aging caves have S. coronoidis The species are kept at constant temperature, constant humidity, and relatively airtight, which is conducive to allowing them to inoculate naturally again to achieve the purpose of growing "golden flowers", but it still cannot effectively solve the problem of the low concentration of S. The number of "golden flowers" is small and not common, some of the pressed Liubao teas are not easy to produce "golden flowers", the aging time is long, the quality is unstable, difficult to control, limited by space, and easy to be polluted.
