Technical Field

the invention relates to the field of health-care tea preparation, in particular to a processing method of ganoderma lucidum green tea.

Background

ganoderma (Ganoderma a lucidum) is a high-grade fungus used as both food and medicine, is rich in multiple active ingredients such as polysaccharide, amino acid, protein, alkaloid, etc., and has multiple functions of resisting tumor, resisting virus, reducing cholesterol and blood sugar, improving immunity, etc.

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.

Green Tea (Green Tea), one of the main Tea in China, is a beverage prepared from new leaves or buds of Tea trees by processes of enzyme deactivation, shaping, drying and the like without fermentation. The color of the finished product and the tea soup after brewing are more, and the green style of the fresh tea is preserved. The green tea can prevent cancer, reduce fat and lose weight after being drunk frequently, and can also reduce the harm of nicotine to smokers.

the ganoderma lucidum is organically combined with tea leaves, the development of the health care function of the ganoderma lucidum is carried out, the prospect is wide, but the hypha growth rate of the ganoderma lucidum is reduced due to the influence of tea polyphenol when the tea leaves are inoculated as a culture medium, and meanwhile, the hypha of the ganoderma lucidum is yellowed due to the influence of the tea environment, so that the appearance and the quality are seriously influenced.

Disclosure of Invention

the invention aims to provide a processing method of ganoderma lucidum green tea, which realizes the organic combination of ganoderma lucidum and green 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 ganoderma lucidum green tea comprises the following steps:

(1) domesticating mother bacteria: putting the original strain of the ganoderma lucidum into a tea branch culture medium for culturing, wherein the culturing temperature is 16-25 ℃, the humidity is controlled at 70%, and the domesticated mother strain is obtained after culturing for 4-8 days;

(2) Green tea treatment: soaking a prepared green tea into a slow-release nutrient solution for 10-15 min, taking out the treated green tea, and filling the green tea into a sterilized polypropylene bag for later use;

(3) Inoculation and propagation: adding the treated green tea into the sterilized polypropylene bags, adding 300-500 g of the treated green tea into each bag, adding 0.2-0.4 g of domesticated mother bacteria, binding 2-4 air holes at the position close to the bag opening, hanging the cultivation bags, and cultivating for 15-20 days, wherein the temperature is controlled at 25-36 ℃, and the humidity is controlled at 60%;

(4) and (4) harvesting a finished product: cutting the cultivation bag when 2/3 in the cultivation bag is full of mycelia, taking out the fermented product, oven drying in an iron pan, and arranging the fermented product into strips to obtain Ganoderma green tea.

Further, the formula of the branch culture medium comprises tea branch powder, beanstalk, wheat bran, gypsum powder, molasses and tap water, and the weight ratio of the formula is 40:8:10:1: 65.

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

Tea polyphenol contained in tea can inhibit the spawn running time of ganoderma lucidum, so that the spawn running curve of the ganoderma lucidum is backward, the tea can go bad and become bad by too long spawn running, and the ganoderma lucidum cultured by taking tea branch powder as a culture medium is adaptive to other contents of tea polyphenol and tea trees, so that the affinity of cultured mother bacteria to the tea is strong, the success rate of direct inoculation is improved, and the spawn running is accelerated.

the purpose of baking with an iron pan is as follows:

because the tea water content after fermentation spawn running is too high, hypha and tea are adhered to form a mass, the tea can be separated and arranged only after being baked, and the fungi on the surface of the tea can be preserved for a long time only by inactivation, but the traditional drying means can lead the hypha on the surface to turn yellow or burn out, and the mode of baking by separating small fire by adopting an iron pan can avoid the hypha from turning yellow, thereby ensuring the appearance phase.

Selection of spawn running temperature:

Hypha cultivated by a traditional tea culture medium can turn yellow, and meanwhile, fruiting can be realized at a too low temperature, in order to ensure the quality phase of the hypha, when the hypha growth temperature of ganoderma lucidum is 25-36 ℃, the hypha growth speed is high, the hypha is white, and a large amount of hypha is contained in a finished product, but the fruiting cannot be realized.

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 very strong affinity to tealeaves, and through adopting the bagging-off to grow fungus, let the tealeaves as expanding the basement of cultivateing, it is faster to grow a speed, solves the lower problem of the slower survival rate of the speed of growing a hair after the mother fungus inoculation.

(2) This application combines glossy ganoderma fungus and green tea, utilizes the iron pan to toast the inactivation and do not adopt traditional stoving mode, makes glossy ganoderma fungus hypha keep good looks.

(3) The application combines the green tea and the ganoderma lucidum, controls the spawn running temperature and time of the ganoderma lucidum, and enables the ganoderma lucidum green tea obtained by covering a large amount of hypha on the surface of the green tea to be rich in tea polyphenol, amino acid, polysaccharide, malic acid and other effective components.
