Embodiment 1
[0020] 1) Bottling the commonly used PDA potato culture medium, inoculating 4 pieces of Chrysanthemum chrysanthemum bacteria, culturing statically, and culturing on a shaking table until the strain is thicker and bacteria balls appear, and the liquid strain of Chrysanthemum chrysogenum is produced;
[0021] 2) Clean the crabapple leaves after harvesting, dry or sun-dry at 50°C for later use;
[0022] 3) Soak the black tea with boiling water, the amount of black tea added is 0.5%, the soaking time is 30min, filter out the tea leaves after soaking, and the filtrate is set aside;
[0023] 4) Soak the crabapple leaves dried in step 2) in the filtrate obtained in step 3) for 60 min;
[0024] 5) Remove the crabapple leaves soaked in step 4) and put them in polypropylene film bags, then sterilize at 121°C for 30 minutes, and the sample size is 800g per bag;
[0025] 6) Inoculate the golden flower fungus liquid strain obtained in step 1) onto the crabapple leaves in the bag in step 5...
Embodiment 2
[0027] Embodiment 2, with embodiment 1, the difference is,

Abstract
The present invention relates to a production technology of eurotium cristatum malus hupehensis tea. A PDA potato culture medium is bottled; the culture medium is inoculated with 4-6 eurotium cristatum blocks; the eurotium cristatum is subjected to static culture and shaker culture; and an eurotium cristatum liquid strain is manufactured; malus hupehensis leaves are washed cleaned; the washed malus hupehensis leaves are dried or sun-dried; black tea is soaked using boiling water; the soaked black tea is filtered to obtain a filtrate; the malus hupehensis leaves are soaked in the black tea filtrate; the soaked malus hupehensis leaves are taken out; the taken out malus hupehensis leaves are packaged using thin polypropylene film bags; the packaged malus hupehensis leaves are sterilized; themalus hupehensis leaves are inoculated with the eurotium cristatum liquid strain; the eurotium cristatum liquid strain is cultured and fermented until the eurotium cristatum grows fully on inside andoutside the malus hupehensis leaf culture medium; the cultured and fermented malus hupehensis leaves are baked; and the baked malus hupehensis leaves are packaged to obtain the eurotium cristatum malus hupehensis tea. Specific malus hupehensis leaves in Shennongjia are used as a raw material; the treated malus hupehensis tea is inoculated with the eurotium cristatum for fermentation; the fermentation by the eurotium cristatum can degrade tannin, alkaloid, etc., and starch; and the obtained eurotium cristatum malus hupehensis tea has a brownish red color after brewing, is free of crude green taste of traditional malus hupehensis tea and sweet in taste, and has effects of promoting digestion, lowering blood lipid, dissolving fat, regulating sugarmetabolism, etc.
Description
technical field [0001] The invention belongs to the field of food fermentation, and in particular relates to a production process of golden flower crabapple tea. Background technique [0002] Eurotium cristutum, commonly known as "Golden Flower Fungus", is a fungus belonging to the genus Eurotium cristutum in the family Phytomycetaceae. It commonly grows on black brick tea and is a probiotic. According to scientific research, Saccharomyces coronis can secrete amylase and oxidase in tea, which can catalyze the conversion of starch into monosaccharides, oxidize polyphenols, make tea soup brown and red, and eliminate the rough green taste. It is more mellow and refreshing in taste, sweet and smooth. It has strong functions of promoting digestion, lowering blood fat, dissolving fat, and regulating carbohydratemetabolism. The size of its particles will change with changes in humidity and other factors. When it is lush, it looks like "Milan", and when it shrinks, it will become...
