Description
Technical field
The present invention relates to tea technology field, particularly relate to the production technology of the instant black tea of a kind of high theaflavin.
Background technology
Black tea is the stub teas of international tea market, accounts for the 80% of teas general trade amount.Nineteen nineties
In the past, China black tea, with aboundresources, the advantage such as yield is big, process technology is advanced, occupied the most leading ground in the international market
Position, and occupy the 60%～70% of whole international black tea market.Along with state's tea industry such as Kenya, Sri Lanka, India are adding
The technical progress of work and at the supremacy clause of the aspects such as weather, local tea variety, soil so that nearest 20 years red due to China
The universal flavour of tea is thin, and dense intensity and convergence are less than India, Sri Lanka and Kenya's black tea, competitiveness in the international market
The highest, yield is gradually reduced with export volume.
Research confirms, theaflavin is one of quality component of most critical in black tea, and the height of its content not only affects red
The dry dark brown pool of tea, millet paste soup color and millet paste flavour, and affect the physiological function drinking black tea, theaflavin in China black tea
Content be generally 0.3%～0.7%, (big far below the theaflavin content in state's black tea such as Kenya, Sri Lanka, India
Many higher than 1.2%), and during abrownin content height, soup color shades, flavour is thin, based on the problems referred to above, if with commodity black tea being
Raw material, in the course of processing, is constituted situation as object of reference using superfine black tea component, is suitably adjusted constituent content, and suitable carries
The content of this active substance of high theaflavin, and reduce the content even removing abrownin, go after profits and advoid disadvantages, quantitative assorted instant tea
Component is constituted, then can obtain in component and superfine black tea reaches unanimity the instant black tea product of even mouthfeel, color and luster more high-quality,
Improve product quality, meet and drink requirement, it is also possible to effectively solve noticeable content of beary metal and pesticide in tea products
Residue problem.
