Description
Technical field
The present invention relates to Tea Processing technology field, more particularly to a kind of selenium-rich black tea processing method.
Background technology
Se rich tea has lowering blood-fat and reducing weight, prevents cardiovascular and cerebrovascular disease.Modern scientific research and clinical trial are confirmed, drink tea the blood fat and cholesterol that can be reduced in blood, making body becomes slim and graceful, because the result of phenol derivatives, aromatic substance, amino acids material, the vitamin substances comprehensive coordination in tea, particularly Tea Polyphenols and theine and ascorbic comprehensive function, fat oxidation can be promoted, helped digest, lowering blood-fat and reducing weight.Additionally, Tea Polyphenols energy dissolved fat and vitamin C can then promote cholesterol to excrete.Tea is sweet peaceful containing tea in itself, and it is rather to improve vascular toughness that tea is sweet, does not allow blood vessel easily rupturable.
Se rich tea is mainly reflected in some effective chemical compositions and multivitamin coordinative role to the anti-aging effects of human body, especially Tea Polyphenols, caffeine, vitamin C, aromatic substance, lipopolysaccharides etc., the elasticity of human body cardiac activity and blood vessel can be strengthened, suppress artery sclerosis, reduce the incidence of disease of hypertension and coronary heart disease, strengthen immunity, so that anti-aging, makes one to obtain long-lived.Add selenium with vitamin C, vitamin E with three mixture of synthesis in food, can increase man's lifespan, and these wholesome elements are just rich in selenium-enriched tea leaf.
Current Se rich tea is originated from selenium-rich ground mostly, and price is higher.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of selenium-rich black tea processing method of artificial addition selenium element.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：One selenium-rich black tea processing method, comprises the following steps：
（1）, fresh leaf is sent directly into the baking oven of 165+/- 5 DEG C, drum hot blast is turned over and blown tealeaves 13-15 minutes, then tealeaves is taken out；
（2）, tealeaves spread out on the curtain that withers by 3-4 cm thicks, withering temperature is 36-38 DEG C, and withering time is 2-3 hours, and leaf is turned over once every half an hour；
（3）, knead：Withered tea leaves are put to 52-57 DEG C of hot pot, heat is rubbed 40 minutes；Room temperature is cooled to, is spread 2-2.5 hours, then put to 68-75 DEG C of hot pot, heat is rubbed 15 minutes；
（4）, one time fermentation：Tea spreading after kneading is put in fermenting cellar, leaf-spreading thickness be 5~
7 centimetres, fermentation room temperature is 32-36 DEG C, and fermentation time is two and one-half- hours；
（5）, secondary fermentation：One time fermentation tealeaves is shaken apart, room temperature is cooled to and is deposited half a day, then spread in fermenting cellar, leaf-spreading thickness is 4 centimetres, and fermentation room temperature is 38-42 DEG C, and fermentation time is 2.5 hours；
（6）, once bakee：By the tealeaves after secondary fermentation, microwave drying, to water content 7.5-8.5%, is taken out after being cooled to normal temperature under vacuum
；
（7）, in the sodium selenite that tealeaves surface spray concentration is 2.5%/selenic acid sodium solution；
（8）, secondary baking：By tealeaves microwave drying under vacuum again, taken out when to its water content being 3%-3.5%.
The present invention obtain beneficial effect be：The selenium-rich black tea processing method that the present invention is provided is simple to operate, by vacuum microwave drying, it is to avoid vitamin C, the vitamin E oxidation in tealeaves, by manually plus selenium, improve the Se content in tealeaves, beneficial health.
Specific embodiment
Used as a kind of specific embodiment of the invention, a selenium-rich black tea processing method is comprised the following steps：
（1）, fresh leaf is sent directly into the baking oven of 165+/- 5 DEG C, drum hot blast is turned over and blown tealeaves 13-15 minutes, then tealeaves is taken out；
（2）, tealeaves spread out on the curtain that withers by 3-4 cm thicks, withering temperature is 36-38 DEG C, and withering time is 2-3 hours, and leaf is turned over once every half an hour；
（3）, knead：Withered tea leaves are put to 52-57 DEG C of hot pot, heat is rubbed 40 minutes；Room temperature is cooled to, is spread 2-2.5 hours, then put to 68-75 DEG C of hot pot, heat is rubbed 15 minutes；
（4）, one time fermentation：Tea spreading after kneading is put in fermenting cellar, leaf-spreading thickness be 5~
