Abstract

The invention discloses a fermented tea and a preparation method thereof. The fermented tea comprises the following raw materials in parts by weight: 2-8 parts of fermented jerusalem artichoke powder and 92-98 parts of fermented tea leaves. The fermented jerusalem artichoke powder and the fermented tea leaves are uniformly mixed so as to obtain the fermented tea. The fermented jerusalem artichoke powder and the fermented tea leaves are obtained by adopting microbial fermentation so as to remove heavy metal residues and pesticide residues. Cooperation between tea polyphenol and the jerusalem artichoke powder is utilized to reduce the body weight and liver weight of hyperlipidemia patients. The content of high-density lipoprotein cholesterol is raised to clear accumulated cholesterol on artery vessel walls, and reduce the contents of triglyceride and total cholesterol so as to realize the object of decreasing blood lipid. A combination of the tea polyphenol and the jerusalem artichoke powder also has a strong effect of inhibiting converzyme activity so as to play an effect in reducing blood pressure. The combination of the tea polyphenol and the jerusalem artichoke powder has an effect of adjusting glycometabolism disorders of human bodies, and can lower blood sugar levels so as to effectively prevent and treat diabetes.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a fermented tea and a preparation method thereof. Background technique [0002] With the development of the economy, while people are improving their quality of life, due to the general lack of exercise, the problem of overnutrition is serious, and the three highs follow. The three highs are high blood pressure, high blood fat, and high blood sugar. After cancer and tumors, the third largest type of disease that threatens human health, about 160 million people in the world suffer from it, and China accounts for 20%. [0003] On the other hand, tealeaves is as a kind of natural beverage, and people's daily drinking rate is high; Drink tea commonly used to reach the purpose of lowering blood pressure, blood fat and blood sugar; Insect pests, it is inevitable to use pesticides to spray tea leaves, and due to environmental pollution, the amount of drug residues an...
