Embodiment 1

[0039] A processing method of Cordyceps militaris fermented dark tea, characterized in that the production comprises the following steps: a. Selecting tea leaves: selecting fresh tea leaves, spring tea, summer tea and all types of tea;

[0040] b. Finishing: It can be done by frying or steaming or soaking green or radiation;

[0041] c. Initial kneading: use a kneading machine to knead the finished tea leaves, and wait until the young black tea leaves are formed into strips and the thick old leaves are wrinkled; the kneading machine speed is 20-60 rpm, and the kneading time is 10-20 minutes , and make up the tea moisture to 50%-90%;

[0042] d. Sterilization: Sterilize the tea leaves after rolling, and the sterility assurance level SAL is 10 -6 ;

[0043] e. Heap fermentation: the tea leaves obtained in the sterilization step are evenly mixed with the liquid strain of Cordyceps militaris in a sterile environment, put into sterile utensils, and carry out fermentation and cult...

Embodiment 2

[0054] The present invention produces 10 kg of fermented black tea from Cordyceps militaris, which consists of 9 kg of tea leaves and 1 kg of liquid strain of Cordyceps militaris.

[0055] Preparation of Cordyceps militaris liquid strain:

[0056] (1) Take the Cordyceps militaris strain, under aseptic conditions, pick a small amount of mycelium with an inoculation needle, insert it into a 9cm PDA plate, activate and cultivate it for 3 days, the culture temperature is 30°C, and natural light;

[0057] (2) After the activation culture, use an inoculation needle to pick a small amount of mycelia and transfer it to PD medium, and culture it in a shaker flask for 2 days, the culture temperature is 30°C, and the rotation speed is 20rpm;

[0058] (3) After the shake flask culture, transfer to the improved PD medium, the inoculum size is 5%, and the fermentation culture is 7 days, the culture temperature is 30°C, and the rotation speed is 20rpm;

[0059] (4) After fermentation and cult...

Embodiment 3

[0071] In this example, 50 kg of fermented black tea from Cordyceps militaris was prepared, which consisted of 42 kg of tea leaves and 8 kg of liquid strain of Cordyceps militaris.

[0072] Preparation of Cordyceps militaris liquid strain:

[0073] (1) Take the Cordyceps militaris strain, under aseptic conditions, pick a small amount of mycelium with an inoculation needle, insert it into a 9cm PDA plate, activate and cultivate for 5 days, the culture temperature is 25°C, and natural light;

[0074] (2) After the activation culture, a small amount of hyphae was picked with an inoculation needle and transferred into PD medium, and cultured in shake flasks for 6 days, the culture temperature was 20°C, and the rotation speed was 110rpm;

[0075] (3) After the shake flask culture, transfer to the improved PD medium, the inoculum size is 20%, and the fermentation culture is 14 days, the culture temperature is 20°C, and the rotation speed is 110rpm;

[0076] (4) After fermentation a...

Abstract

The invention relates to a processing method for cordyceps militaris fermented black tea. The processing method is characterized in that the cordyceps militaris fermented black tea comprises 80-90 weight percent of tea leaves and 10-20 percent of cordyceps militaris liquid strain. The processing method comprises the steps of tea selecting, deactivation, initial kneading, sterilizing, pile fermentation, secondary kneading, baking and packaging. According to processing method disclosed by the invention, by fully utilizing a unique process of processing black tea and creatively combining the black tea with medicinal and edible fungus cordyceps militaris through the combination of the characteristics that the cordyceps militaris easily grows and is high in nutrient value, the nutrient value of the black tea is greatly increased. The cordyceps militaris fermented black tea has the health efficacy of improving the immunity, reducing cholesterol, preventing diabetes mellitus, cardiovascular and cerebrovascular diseases and the like.

Description

technical field [0001] The invention relates to a processing method of fermented dark tea by Cordyceps militaris. Background technique [0002] With the increase of people's health needs, various health teas have emerged under the support of modern biotechnology. Among them, the combination of edible and medicinal fungi and tea is the most popular. Among the edible and medicinal fungi, the research on Cordyceps militaris is more prominent. [0003] Cordyceps militaris (Cordyceps. Militaris (L.Fr) Link), also known as Cordyceps militaris and Cordyceps militaris, is a model species of the genus Cordyceps (Clavicipitaceae) of the phylum Ascomycotina. Traditional Chinese medicine believes that Cordyceps enters the two meridians of the lung and kidney, which can not only nourish the lung yin, but also nourish the kidney yang. The only traditional Chinese medicine that can balance and regulate Yin and Yang at the same time. On March 16, 2009, the Ministry of Health approved Co...
