Natural pile fermentation and golden cleistothecium shaped ascospore reproducing method of bulk Pu'er fermented tea with golden cleistothecium shaped ascospore

Abstract

The invention belongs to the technical field of tea leaf processing, and discloses a natural pile fermentation and golden cleistothecium shaped ascospore reproducing method of bulk Pu'er fermented tea with golden cleistothecium shaped ascospore. The natural pile fermentation and golden cleistothecium shaped ascospore reproducing method comprises the following steps of performing pure culture on golden cleistothecium shaped ascospore by using Yunnan grandifoliate sunned semi-finished tea as a substrate through golden cleistothecium shaped ascospore prepared by leaching tea leaves rich in golden cleistothecium shaped ascospore; then performing inoculation on the sunned semi-finished tea with strains obtained through pure culture in a certain proportion, and performing solid state fermentation; performing inoculation on the sunned semi-finished tea with strains rich in golden cleistothecium shaped ascospore and obtained through the solid state fermentation in a certain proportion, and performing pile fermentation; and in the pile fermentation process, enabling the golden cleistothecium shaped ascospore to be in mass reproduction so as to produce a golden cleistothecium shaped ascospore reproducing phenomenon, wherein the number of eurotium cristatum in finished products of bulk Pu'er tea is greater than or equal to 50*10<4>CFU/g. According to the natural pile fermentation and golden cleistothecium shaped ascospore reproducing method disclosed by the invention, combination of solid state fermentation of a modern biotechnology and conventional pile fermentation is realized in natural pile fermentation of Pu'er fermented tea for the first time, Pu'er tea rich in golden cleistothecium shaped ascospore is produced, and the health-care efficacy and the quality of the Pu'er tea are improved; and the method disclosed by the invention is simple and easy to operate, has maneuverability and has wide application prospects.

Description

Technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a natural blooming method of golden flower Pu'er ripe tea loose tea. Background technique [0002] Pu'er tea is made from dried green hair tea made from fresh leaves of Yunnan big-leaf tea tree [Camelliasinensis (Linn) var.assamica (Masters Kitamura)], and is made with specific processing techniques within the scope of protection of geographical indications, with unique qualities Characteristics of tea leaves. According to its processing technology and quality characteristics, Pu'er tea is divided into two types: Pu'er raw tea and Pu'er ripe tea. The processing process of Pu'er ripe tea is Yunnan large-leaved fresh leaves--degradation--kneading--sun drying--mao tea sorting--mixing--tidal water pile--natural drying--ageing--screening and sorting Tick-dry-finished product. Studies have shown that ripe Pu'er tea can control lipid metabolism, resist oxidation, scaven...
