Preparation method of black tea containing mulberry leaves

Abstract

The invention discloses a preparation method of black tea containing mulberry leaves. The method takes tender leaves of mulberries in May or June as raw material, and comprises the following steps: picking the fresh leaves, withering, rolling, fermenting, deblocking, baking and packaging. After the preparation method is adopted, the multiple bioactive substances which are good for a human body in the mulberry leaves are reserved to the utmost extent; in the processing process, the macromolecular substances which cannot be easily absorbed and utilized by the human body in the mulberry leaves have a series of physicochemical changes and then are converted into aroma and taste components and low molecular weight bioactive substances which are easily absorbed by the human body; furthermore, the tea is golden in color, mellow in tea soup and sweet in tea flavor, and not only has the characteristics of the traditional black tea, but also has the effects of reducing blood sugar, blood fat and blood pressure, inhibiting arteriosclerosis, resisting bacteria, resisting oxidation, resisting aging, clearing internal heat, improving eyesight, etc.

Description

technical field [0001] The invention belongs to a food (health food) preparation method, in particular to a preparation method of mulberry leaf black tea. Background technique [0002] "Compendium of Materia Medica" records that mulberry leaves are a medicine for hands and feet, which can cure cough due to fatigue, improve eyesight and grow hair, and relieve thirst. Mulberry is a precious resource for both medicine and food. Scientific research at home and abroad has confirmed the nutritional ingredients, pharmacologically active ingredients and their mechanism of action of mulberry resources. It contains flavonoids, amino acids, alkaloids, volatile oils, steroids, sugars, etc. These chemical components have various pharmacological activities or clinical curative effects such as lowering blood pressure, lowering blood fat, anti-inflammation, anti-virus, anti-aging, and weight loss. [0003] Studies have shown that mulberry leaves are non-toxic and harmless to humans or ...

AI Technical Summary

Problems solved by technology

[0005] But at present, most of the mulberry leaves are traditionally used as medicine, and a small amount is used to make substitute teas today, but the processing technology of these substitute teas is not standardized, and some fresh mulberry leaves are directly dried in the sun or dried in the shade for drinking, However, the process is still difficult to finalize, and there is no unified standard for the technical parameters of key control points in each process, resulting in unstable tea processing quality and directly affecting product quality (color, aroma, taste, shape). It also affects the transformation of the ingredients contained in mulberry leaves and the retention of active ingredients, reducing the medicinal and health effects of the product
