Problems solved by technology

However, because the tea powder contains a variety of bacteria, it is impossible to control the blooming of loose tea, and the high-temperature and high-pressure steam treatment after inoculation will destroy the activity of the golden flower fungus added to the tea, and the growth advantage of the coronoid fungus cannot be guaranteed. no golden flower

Abstract

The invention discloses a technology for carrying out fungus growing on loose tea. The technology comprises the following steps: (1) preparing a fermenting agent, namely, separating out eurotium cristatum from fuzhuan tea, and preparing to obtain the solid pure strain fermenting agent; (2) treating raw dark green tea raw material, namely, removing the impurities in the raw dark green tea, steaming, carrying out pile fermentation and then feeding tea juice; (3) carrying out steaming inoculation and fungus growing, namely, steaming the raw dark green tea with the tea juice, then immediately feeding the solid pure strain fermenting agent and inoculating; after that, putting the inoculated raw dark green tea into a fungus growing culture room, and carrying out fungus growing culture; and (4) drying and packaging, namely, drying after fungus growing, and directly packaging the dried loose tea. After the technology is adopted, the fungus growing time is shortened, the bacterial pollution rate can be reduced in the fungus growing process of the loose tea, the problems that the existing loose tea is hard in fungus growing and easy in bacterial growth can be solved, the fungus growing rate of the loose tea reaches up to 100%, and the tea is widespread in golden flowers on the surface and the granules are plump.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a technique for blooming loose tea. Background technique [0002] Fuzhuan tea is the most distinctive dark tea product. "Flower" is the characteristic symbol of Fuzhuan tea and the key technology of its production. It is golden yellow and spherical in shape. It can grow and develop in pressed tea under suitable temperature and humidity conditions, secrete a series of enzymes, and promote the transformation of substances in tea, thus forming many functional ingredients that are beneficial to the human body. Studies have shown that the "Golden Flower" in Fu tea is very similar to Ganoderma lucidum spore powder, which can effectively regulate human metabolism, and has strong effects of lowering fat, lowering blood pressure, regulating carbohydrate metabolism, and improving human immunity. The amount of golden flowers in the tea is regarded as the quality of Fuzhuan tea. [0003] Howe...
