Technical Field

The invention relates to the field of scented tea preparation, and particularly relates to a processing method of cordyceps sinensis-jasmine-Pu' er tea.

Background

Cordyceps sinensis is an ascomycete parasitic on the larvae of insects in the family Hepialidae. Belongs to the ergot mycology, and sclerotium of the ergot mycosis is a rare Chinese herbal medicine in China. The pharmacological research of China in the year proves that no matter natural cordyceps or the mycelia thereof have the effects of calming, resisting fatigue, resisting anoxia, enhancing immunity, resisting inflammation, resisting arrhythmia and resisting tumors, the natural cordyceps is only produced in alpine regions of China and has very limited yield, so the natural cordyceps is expensive and is not in demand, but through the research of the separation and cultivation of the cordyceps mycelia by a plurality of scholars, the pharmacological action and the component content of the cordyceps mycelia are basically consistent with those of the natural cordyceps, so the source of the cordyceps sinensis, which is a famous and precious medicine, is enriched, and the cordyceps sinensis can be more easily served to the public.

The tea is a health drink, and medicinal bacteria and tea are combined by using the medicinal bacteria and the tea, chemical components of the tea and the inoculated medicinal bacteria are combined, the medicinal bacteria and the tea are fully blended through fermentation, organic nutrient substances are easily absorbed by a human body, and the research direction of a new tea product is opened up.

As traditional scented tea, jasmine tea has a huge market at home and abroad, and has been over 1000 years of history till now, the tea fragrance and the jasmine fragrance are interactively fused, so that the scented jasmine has no smell and is the reputation of serving as the first fragrance among people, and the jasmine tea is a popular product of the jasmine tea, has a wide production area, high yield and rich varieties.

If the cordyceps sinensis is combined with jasmine tea, the effect and taste of the cordyceps sinensis can be imagined to be loved by many people, but the jasmine tea is different from common tea, a scenting process is carried out, the temperature in the scenting process is high, the cordyceps sinensis is easy to die, the cordyceps sinensis is difficult to be completely separated from a host for cultivation, the survival rate of the cordyceps sinensis directly inoculated on the tea is extremely low, and the taste can be seriously influenced if the cordyceps sinensis is directly added into the host.

disclosure of Invention

The invention aims to provide a processing method of cordyceps sinensis jasmine Pu 'er tea, which realizes inoculation of cordyceps sinensis on jasmine Pu' er tea and develops a novel health-care tea variety.

in order to achieve the purpose, the technical scheme of the invention is as follows:

A processing method of cordyceps sinensis jasmine Pu' er tea comprises the following steps:

(1) culturing mother bacteria: washing fresh Cordyceps sinensis with 75% alcohol solution to sterilize the surface, cleaning with clear water, removing shell of Cordyceps sinensis, cutting the inner thallus into pieces, respectively placing into prepared tea tree culture medium, culturing at constant temperature of 21-25 deg.C for 5-10 days to obtain mother strain;

(2) inoculating and spawning: putting prepared Pu 'er tea into 18X33cm polypropylene bags, adding 0.2-0.5 g of mother bacteria, putting each bag with dry material weight of 500g into a thermostatic chamber for cultivation, culturing at the relative humidity of 65% and the temperature of 13-16 ℃ for 15-20 days, and cutting off the polypropylene bags to obtain inoculated Pu' er tea;

(3) Scenting and inactivating: carrying out layered heap scenting on the inoculated Pu ' er tea and jasmine, separating the Pu ' er tea and the jasmine through non-woven fabrics in a mode of one Pu ' er tea layer by one jasmine, controlling the temperature of the heap scenting to be 35-38 ℃, scenting the jasmine for 2-5 hours, removing the jasmine, and spreading the scented tea for cooling;

(4) Drying and bagging: spreading the spread and cooled tea leaves on an iron pan, baking the bottom of the iron pan with black olive pit charcoal with a small fire, taking out the tea leaves after baking for 15-30 min, naturally spreading for cooling, and bagging to obtain the cordyceps sinensis jasmine Pu' er tea.

Further, the formula of the tea tree culture medium comprises tea tree branch powder, molasses, glucose, agar, peptone and distilled water, wherein the tea tree branch powder is prepared by cleaning tea tree branches and crushing the cleaned tea tree branches into 200-mesh fine powder, and the weight ratio of the raw materials of the tea tree culture medium is 5:2:1:4:3: 10.

The purpose of culturing mother bacteria by using the tea tree culture medium is as follows:

the survival rate of the cordyceps sinensis inoculated by separating from the host is low, and the cordyceps sinensis mother bacteria cultured by taking the tea branch powder as the culture medium is adapted to the nutritional structure of tea trees, so that the affinity of the cultured mother bacteria to tea is strong, and the survival rate of direct inoculation is improved.

The aim of the layered heap scenting by using non-woven fabrics is as follows:

This application adopts the mode of one deck jasmine flower one deck tealeaves to pile the basement when piling the basement to all separate through the non-woven fabrics between jasmine flower and the tealeaves, thereby can not mutual pollution when guaranteeing to pile the basement, and also save the screening process, because traditional screening needs the shake to sieve the flower, shakes the hypha of the chinese caterpillar fungus on the tealeaves easily.

the purpose of baking by using an iron pan and black olive pit charcoal is as follows:

because the jasmine tea preparation process needs to be subjected to the scenting step, the water content of the scented tea is too high, and the cordyceps sinensis on the surface of the tea can be preserved for a long time only by inactivation, but the hypha on the surface is yellow or burnt out by the traditional drying means, the hypha can be prevented from being yellow by adopting a mode of baking the tea by separating a small fire by an iron pot, the condition phase is ensured, and the charcoal fragrance of the tea blended into the black olive core has special flavor by adopting the black olive core.

The invention has the advantages that:

(1) This application adopts tea branch powder as the major ingredient of culture medium, and the mother fungus of cultivateing has extremely strong affinity to tealeaves, through adopting the bagging-off fermentation, lets the tealeaves cultivate as the solid medium that expands to bank up, and the speed of growing hair is faster, and tealeaves surface covering hypha is even, need not add other auxiliary materials, makes the back tealeaves of growing hair directly can take, saves the filtration process, solves the lower problem of the slower survival rate of the speed of growing hair after the mother fungus inoculation.

(2) According to the application, the cordyceps sinensis and the jasmine tea are combined, the cordyceps sinensis is guaranteed not to be polluted through a layered scenting process and is simultaneously baked and inactivated by using an iron pot, a traditional drying mode is not adopted, the cordyceps sinensis is enabled to keep a good quality phase to be attached to the surface of a jasmine tea leaf, and a unique quality phase and a fused taste are formed.

(3) The application strictly controls the height of the heap scenting and the scenting temperature, and solves the problem that hyphae are burnt and discolored due to overhigh scenting temperature in the prior art.
