Description
Technical field
The present invention relates to the preparation method of black tea product, and in particular to a kind of to prepare high theaflavin broken black tea and high tea simultaneously
The method of flavine instant black tea powder.
Background technology
Black tea is one of most popular healthy beverage in the whole world.The special of black tea is the essential of its process
Full fermentation process, the technique main purpose be by using polyphenol oxidase activity, by the acerbity components in tea fresh leaves, (tea is more
Phenol) theaflavin material is oxidative polymerization into, so that it is red gorgeous bright to form black tea, the quality characteristic such as fresh, refreshing, mellow and harmonious.Research shows that tea is yellow
Element has the bioactivity more powerful than Tea Polyphenols, including anti-oxidant, anticancer, suppression bacterium, preventing and treating cardiovascular and cerebrovascular disease etc., plus
Its upper content in the black tea of normal fermentation is low, and theaflavin prepared by purification is referred to as " soft gold ".Therefore with high content tea
The black tea of flavine, and high content black tea instant tea are the new ideas of black tea research and trade.
Currently, by endogenous enzymes, either exogenous enzymes prepare the instant tea or high theaflavin content of high theaflavin
The method of black tea, but these methods mostly add non-tealeaves class material, and high theaflavin broken black tea can not be prepared simultaneously
With high theaflavin instant black tea powder.
The content of the invention
The technical problem to be solved in the present invention is to overcome deficiency of the prior art there is provided a kind of while preparing high tea Huang
The method of plain broken black tea and high theaflavin instant black tea powder.
To solve technical problem, solution of the invention is:
There is provided a kind of while preparing high theaflavin broken black tea and the method for high theaflavin instant black tea powder, including following step
Suddenly:
Step (1):By tea fresh leaves A and pure water, with mass ratio 1:After 1 is mixed, the mixing tea liquid is broken into homogenate,
The homogenate is filtered with 200 eye mesh screens, is then carried out centrifugal treating with 15000~20000 turns/min speed, that is, is obtained fresh
Tea juice;Wherein, tea fresh leaves A is leaflet plant tea, and is the leaf of one bud of tea three, the leaf of one bud of tea four or its combination;
Step (2):Tea fresh leaves B is directly placed into 4 hours of frost in -20 DEG C of freezers, then taken out;Wherein, tea fresh leaves B
For large leaf tea, and it is the leaf of one bud of tea one, tea two leaves and a bud or its combination;
Step (3):The tea juice that will be obtained in the tealeaves freezed in step (2) and step (1), with mass ratio 1:5~1:8
After being mixed, logical oxygen stirring fermentation is carried out, fermentation temperature is 30 DEG C~40 DEG C, fermentation time is 10min~30min, ventilation
Measure as 10L/min~30L/min;
Step (4):By fermented feed liquid obtained in step (3) with 200~300 mesh sieve net filtrations, filtrate and filter are obtained
Slag, filter residue progress CTC is rubbed and cut, then dries, obtains high theaflavin broken black tea;
Step (5):Obtained filtrate in step (4) is carried out after centrifugal treating with 15000~20000 turns/min speed,
High theaflavin instant black tea powder is made by being spray-dried or being freeze-dried after supernatant concentration.
In the present invention, the tea fresh leaves are to censure not processed and other any processing the tealeaves from after tea tree, described
Screen cloth is double gauze.
Compared with prior art, the beneficial effects of the invention are as follows:
(1) method being homogenized using fresh leaf fully improves the activity of polyphenol oxidase, while utilizing the method for freezing crushing
Quick crashing cell membrane, improves the enzymatic oxidation reaction efficiency between polyphenol oxidase and Tea Polyphenols, the speed not only directly improved
The content of theaflavin in molten black tea, while also considerably increasing the theaflavin content in broken black tea;
(2) present invention does not add any non-tealeaves material, it is ensured that the security of product;
(3) this method is prepared for the instant black tea powder of high theaflavin, fully profit while high theaflavin broken black tea is prepared
With tea resources, greatly reduce the wasting of resources, also shorten the fermentation time of conventional black processing, improve efficiency.
