Problems solved by technology

[0012] Aiming at the problems that the existing willow leaf tea has a certain coldness and is prone to green and astringent bitter taste and the color of the tea soup is too light when drinking, while the existing black tea has the functions of lowering blood fat and improving gastrointestinal function, but the effect is not obvious, etc., The present invention provides a kind of fermentation using the coronoid saccharomyces, which can not only solve the green and astringent bitterness in willow leaf tea, but also solve the cold and cold defect of willow leaf tea with black tea, and ensure the tea leaves are fermented. A tea processing method that has good flower uniformity, is easy to drink, can maintain the original quality of traditional fermented tea and retain functional ingredients to the greatest extent

Abstract

The invention provides a technology for utilizing cyclocarya paliurus leaves and raw dark green tea for fermentation to make healthcare tea. A functionality tea product is obtained through the steps of pile fermentation, secondary fermentation, infrared ray fixing and the like. By means of the secondary fermentation mode, leaching speed of steam sterilization to cyclocarya paliurus leaf tea can be reduced, conversion of polysaccharide substances in the cyclocarya paliurus leaves is also effectively restrained, functionality ingredients of the cyclocarya paliurus leaves are also retained while the mouthfeel of tea soup is improved, reaction with tea polyphenols is avoided, uniform growth of golden flowers can be ensured, and quality of the composite tea is improved. A large amount of eurotium cristatum spore powder is adopted for carrying out fast short-time fermentation and long-time fermentation, and the problem that the cyclocarya paliurus leaf tea is green, astringent and bitter is solved thoroughly; meanwhile, growth of infectious microbes is reduced, mildewing of raw dark green tea is avoided, and the influence on original flavor of the tea from a culture medium in eurotium cristatum liquid is avoided.

Description

technical field [0001] The invention mainly relates to a kind of tea making, in particular to a process for making health-care tea by fermenting willow leaves and black hair tea. Background technique [0002] Money willow, also known as green money willow, money tree, money tree. Belonging to Juglandaceae, deciduous tree, tree height 10-30 meters; bark gray; branches dark brown, flowering period 4-5 months, leaves leathery, odd pinnate compound leaves. The infructescence axis is 25-30 cm long, and the fruit has leathery horizontal disc-shaped wings, and the ripening period is from July to September. [0003] Money willow leaf contains the original ecological hypoglycemic factor chain, which is mainly composed of two original ecological nutrients: inorganic nutrients and organic nutrients, which can effectively and comprehensively regulate the body's glucose metabolism. Organic nutrients: Qianliu tea is rich in organic nutrients such as saponins, flavonoids, polysaccharides...
