Description

A kind of preparation method who hides tea

Technical field

The present invention is a kind of preparation method who hides tea, relates to limit tea product technical field.

Background technology

Green tea is a kind of beverage tea that people use always at present, but the raw material of making green tea can only be used the tender shoots tender leaf of tea tree, and old blade can't be utilized in the tea tree big to its output, that inclusion is abundant.In the physical and chemical index of check, the Tea Polyphenols of green tea, caffeine equal size are higher, and water extraction is on the low side, lacks to keep necessary other benefit materials of health.

Summary of the invention

Can not utilize in the tea tree old blade and include organic substances such as Tea Polyphenols, caffeine higher and water extraction is on the low side in order to overcome existing green tea production, lack the deficiency of keeping aspects such as necessary other benefit materials of health, the present invention will provide a kind of and hide the preparation method of tea and hide tea by the product that this method directly obtains, can not only effectively utilize tea tree in old blade, but also can change and transform the interior letter material of tealeaves, satisfy the health material demand essential to part.

The present invention solves the technical scheme that its technical problem takes: hide tea by following process and operating procedure preparation:

Complete: closed steaming is blue or green.Steam atmosphere, 100 ℃-110 ℃ of temperature, 1-4 hour leaf look is advisable by green flavescence, blade deliquescing behind the last rice steamer.Its objective is blade is heated, keep certain humidity, temperature, increase the soft tender toughness of blade, be beneficial to and take off stalk and knead;

Spreading for cooling: the tealeaves spreading for cooling that will take the dish out of the pot after will completing was opened 2-3 hour, separated in order to the stalk leaf;

Take off stalk: tealeaves is trembled stalk, its branches and leaves are separated, remove tea stalk, contain the stalk amount below 5%;

Fumigation: the blade steaming with separating makes its deliquescing, in order to kneading;

Knead: with blade steaming, deliquescing, knead, rubbing blade becomes and is shaped as suitablely preferably, gently rubs 3-5 minute, and the blade that reaches 70-80% is rubbed wrinkle.Purpose is to impel its leaf-shrinkage, convolution, forms good color and luster and fragrance, promotes the conversion of its internal substance;

Dry: with the blade oven dry, mass dryness fraction makes its fluid loss reach 70-80% and is advisable;

Rub again: dried blade is treated back to rub again when profit is even, slightly heavily rubs when rubbing again 2-3 minute, and the blade that reaches 95-98% is rubbed wrinkle;

Dry again: as to make the fluid loss of blade reach 70-80% and be advisable;

Rub again: treat that blade returns profit when even, slightly rub again again, reach 100% blade and rubbed wrinkle;

Wet heap: promptly ferment, be to make tealeaves change the important procedure of color.With dried tealeaves sheet fumigation 60-90 second, bunch while hot, bunch carry out turning the first time to it after one day and flock together, for turning over surroyal; After this 5-7 day, Cha Duishang has hot gas to emerge, and during 70 ℃-80 ℃ of pile core temperature, turns and flocks together, for turning over two wooden forks; Again 4-5 day after this, dew appears in the heap face, during 70 ℃-75 ℃ of pile core temperature, turns to prick again and pushes away, for turning over three wooden forks.Purpose is to make its tealeaves sheet fermentation evenly, fully;

Dry: blade is carried out drying, and leaf water content is below 3%;

Sub-sieve: screen out the broken foam of tealeaves, fragment;
