Description

Cyclocarya paliurus yellow tea and preparation method thereof
Technical Field
The invention relates to the technical field of tea, and particularly relates to cyclocarya paliurus yellow tea and a preparation method thereof.
Background
Tea drinking is one of seven things for people in China to open the door. Tea culture has a long history in China and goes deep into the mind of people. The consumption of tea leaves is huge, and the quality requirements of the tea leaves are also very exquisite. The yellow tea is a fully fermented tea and is a main tea product in tea culture. The yellow tea is produced mainly in China, Srilanca, India, Kenya and the like. The yellow tea is produced by the steps of picking, withering, rolling, fermenting, drying and the like; has one more fermentation process than green tea. The fermentation refers to the oxidation of tea in the air, and the fermentation action reduces tea polyphenol and tannin in the tea, and generates new components such as theaflavin, thearubigins and the like and aromatic substances such as alcohols, aldehydes, ketones, esters and the like.
Cyclocarya paliurus, another name: cyclocarya paliurus, salix caprae, and ashitaba tree. The plants of the juglandaceae and cyclocarya paliurus are found in more provinces in the south of China and are distributed sporadically. Cyclocarya paliurus is a rare tree species which survives in glacier season and only exists in China. Cyclocarya paliurus is known as panda in the plant world and the third tree in the medical world. The current research proves that the cyclocarya paliurus leaves have the effects of reducing blood sugar, blood pressure and blood fat, enhancing the immunity of the organism and the like.
The tea leaf contains various nutrient elements such as vitamin C, vitamin E and carotene, and has effects of preventing cancer and delaying aging. In the middle of the present tea that utilizes cyclocarya paliurus leaf to make, ubiquitous neglected cyclocarya paliurus leaf active ingredient's utilization effect and taste, the result leads to its product effect to hardly reach the effect of expectation to influence consumer's cognition degree, the leading cause lies in: firstly, the existing processing technology is unreasonable, only a simple tea making method is adopted, the health care effect of the cyclocarya paliurus tea is difficult to exert, and secondly, the nutritional elements contained in the existing tea leaves of the part lacking of the cyclocarya paliurus are also greatly different from the existing tea leaves in taste.
