Embodiment 1

[0019] Example 1: In mid-July, 100 kg of fresh berry tea leaves artificially planted in Siguanyu Village, Luotaping Township, Yongding District, Zhangjiajie City (identified as the small-leaved species of Snake-toothed Grape) were picked, and put into a drum-type greening machine after cooling High-temperature finishing, 10 kg of fresh leaves are fed each time, the finishing temperature is 265°C, and the finishing time is 70-90 seconds; stop the machine and pour the materials into the kneading machine, continue feeding and finishing until the fresh leaves are finished, and get 89.5 kilograms of clinker; Divide the clinker into two kneading machines, turn on the machine and knead for 3 minutes, until the leaf juice overflows the surface of the material, loosen the agglomerated material to dissipate heat for 15 minutes, wrap it tightly with white cotton cloth and pack it for fermentation, the fermentation time is 90 minutes, the initial temperature 33°C, end temperature 48°C, spr...

Embodiment 2

[0020] Example 2: On September 24, 2018, 100 kg of fresh berry tea leaves artificially planted in Siguanyu Village, Luotaping Township, Yongding District, Zhangjiajie City were picked. After cooling down, they were put into a drum-type greening machine for high-temperature greening, and fresh leaves were thrown every time. 10 kg, the finishing temperature is 275°C, and the finishing time is 80-90 seconds; stop the machine and pour the material into the kneading machine, continue feeding and finishing until the fresh leaves are finished, and get 94.2 kg of clinker; divide the clinker into 2 sets Kneading machine, turn on and knead for 3 minutes, until the leaf juice overflows the surface of the material, loosen the agglomerated material to dissipate heat for 10 minutes, wrap it tightly with white cotton cloth and pack it for fermentation, the fermentation time is 90 minutes, the initial temperature is 32°C, and the end temperature is 45°C , spread out the fermentation bag to see...

Embodiment 3

[0021] Embodiment 3: use the raspberry tea extract prepared by the above examples, in the Hunan Animal Experiment Center, do animal model tests according to the Ministry of Health 2003 edition health food efficacy evaluation guidance opinion standard method, the main test results and conclusions are as follows:

[0022] (1) Effect of berry tea extract on antioxidant function

[0023] 40 male SD rats, weighing 180.1-210.6g, were randomly divided into model control group, low, medium and high doses of raspberry tea extract (0.215g / kg, 0.43g / kg, 0.86g / kg) according to body weight, each There were 10 rats in each group, and each group was given different medicinal solutions by intragastric administration every day, the administration volume was 10mL / kg, once a day, for 30 consecutive days, and the model control group was given the same volume of distilled water. After the last gavage, each group was fasted for 16 h (overnight), and then given 50% ethanol 12 mL / kg bw by gavage once...

Abstract

The invention provides a preparation method, product and application of a vine tea extract. The preparation method includes the steps: spreading fresh leaves of vine tea to cool, de-enzyming, then pouring out of a kneader, and continuing to de-enzyme until the fresh leaves are de-enzymed completely; loading the de-enzymed clinker into a kneader and kneading until a leafy juice overflows the surface of the material; loosening and heat-dissipating the material kneaded into lumps, packaging with cotton cloth, and fermenting for 1-2 h at the temperature of 32-50 DEG C; scattering the hot and humidmaterial after fermentation, and drying to obtain raw vine tea; placing the raw vine tea in a shaking screen, shaking and screening by a 120 mesh screen, and thus obtaining the vine tea extract. Themethod has the advantages of simple production process, environmental protection, energy saving and consumption reduction, and significant reduction of production cost. The product can be used for preparing health care products with functions of resisting oxidation, enhancing immunity, reducing blood lipid, protecting liver, clearing throat and the like.
