Description

Loose tea golden flower flowering process

Technical Field

The invention belongs to the technical field of microorganism and food biology, and particularly relates to a flower growing process of loose tea.

Background

Eurotium cristatum is a fungus which is separated and identified from Anhua dark tea Fuzhuan tea at the earliest. The camellia chrysantha is propagated in a large amount in the flower growing process of Anhua dark tea Fuzhuan tea, and a large amount of golden yellow cyst closure shells are formed inside the Fuzhuan tea, so that the camellia chrysantha is obtained. The eurotium cristatum secretes secondary metabolites such as enzyme and polysaccharide, and the like, so that the substances in the black tea are fully converted, the Fuzhuan tea has special fungus flower fragrance, and the characteristics of the Fuzhuan tea such as fragrance, taste and liquor color are distinct. More importantly, researchers find that the Fuzhuan tea has more outstanding effects of reducing fat, losing weight and conditioning intestines and stomach compared with the common black tea, so that eurotium cristatum is a double booster for sensory quality and health effect of the Fuzhuan tea, the number of the golden flowers also becomes a first index for judging the quality of the Fuzhuan tea, and the number of the eurotium cristatum in the Fuzhuan tea is not less than 20 cfu/g tea and 30 cfu/g tea respectively specified in national standard and local standard.

Due to the limitation of temperature and humidity and other environmental factors, the traditional flower growing technology is limited to Fuzhuan tea, but the industrialized flower growing technology of loose tea does not exist, and the golden flower loose tea which is safe to produce, good to drink and effective is produced. Compared with the traditional Fuzhuan tea, the golden flower loose tea has the advantages that: firstly, the tea is portable for drinking, so that the consumption requirements of consumers are met; secondly, the golden flowers are visual, and the quality of the blossoming can be checked without opening the brick tea; thirdly, the flower growing quantity is high, only a small amount of golden flowers can be generated in the middle of a brick tea of the traditional Fuzhuan tea, the flower growing quantity is about 30 ten thousand cfu/g tea, and the flower growing quantity of the golden flower loose tea can be higher than 100 ten thousand cfu/g tea due to the fact that the golden flowers are distributed all over, so that the fungus flower fragrance and the health efficacy of the tea are remarkably superior to those of the Fuzhuan tea. Therefore, the technology for forming stable loose tea flowering, which can be applied to large-scale production, is an important subject in the tea industry and the fermentation industry.

The loose tea flowering technology mostly utilizes a culture solution of golden flower bacteria, some inducers are added to induce the tea to bloom, the operation flow is complex, the eurotium cristatum suspension needs to be prepared in advance, and then the tea is inoculated, so that the pollution of a culture medium or other chemical additives can possibly occur; the dark tea is obtained by selecting old leaves and stalks with higher maturity in the loose tea flowering process, and carrying out the processes of high-temperature enzyme deactivation, rolling, holding, stacking, fermentation, ten-drying and the like, the obtained dark tea has rough appearance, rich but not fine taste and broken leaf bottoms, the flowering effect is not good from the prior art, and the produced golden flowers are smaller. The growing environment requirement of the golden flower is extremely strict in the growing link, the temperature and the humidity need to be regulated and controlled at the same time, and when the regulation and control operation is improper, the growing effect of the loose tea is influenced, so that golden flower particles are small, the growing density is low, the distribution is uneven, and the like, and therefore, the cultivation of the golden flower loose tea with high quality and pure taste is a great challenge to the prior art.

At present, no industrialized automatic black tea loose tea fermentation production line appears on the market temporarily, no fermentation device matched with the production line is provided, a small amount of scientific research fields are provided, and a glass triangular flask and a silica gel plug are mostly adopted in the process of researching the black tea loose tea fermentation process, so that the defects are that: the glass product is easy to break in production, and the potential safety hazard of production is easily caused. The charging bottles which are made of food-grade high-temperature and high-pressure resistant high polymer materials are selected as main fermentation devices to replace the traditional glass charging bottles, can be developed industrially and automatically, can be produced in large quantities, and can ensure the fermentation quality of the loose dark tea are high in application value.

CN104222352A discloses a method for growing flower of loose dark tea golden flower and a temperature and humidity control incubator for the growing process of loose dark tea golden flower. A method for flowering of loose dark tea and golden flower comprises the steps of raw material selection, pile fermentation, tea juice spraying, air steaming, temperature and humidity control flowering, drying and packaging. The temperature and humidity control incubator comprises an atomizer, a sealed interlayer, a temperature and humidity controller, an air drying layer and a culture container: one side of the air drying layer is provided with a hot air inlet; one side of the closed interlayer is provided with a vapor-liquid outlet, and the other side of the closed interlayer is provided with a vapor-liquid inlet; the upper part of the closed interlayer is provided with a sprayer; the temperature and humidity controller is arranged outside the closed interlayer. The patent has the advantages of higher pollution risk, extremely strict requirements on environment and great industrialization difficulty.

CN102640814A discloses a method for making golden flower loose tea without inoculation, which is characterized by comprising the following steps: the method comprises the steps of rapidly alcoholizing dark tea → adjusting the water content of the tea → filling the sample steamed tea → preparing the hair flower container → bagging the tea → cooling → controlling the temperature hair flower → monitoring the hair flower → aging → drying → packaging. The process adopts manual inoculation, has low automation degree, and increases the instability of products caused by errors in manual operation.
