The application of dark green tea powder prepared by a kind of production method for the dark green tea powder in food of the invention, the food
Including baking based food, jelly, ice cream and candy.Dark green tea powder prepared by the present invention can also be subsequent to adopt according to use demand
The ultra micro dark green tea powder of different meshes is fabricated to ball mill or micronizer.
Superfine Dark Green Tea why is selected in step (1) of the present invention, this is because tea polyphenols are Polyphenols of Tea
General name, be to have one of composition of healthcare function in one of main ingredient to form tealeaves color, smell and taste and tealeaves, according to Anhua
Dark Green Tea terrestrial reference, tea stalk is more in the lower Dark Green Tea of rank, and the main component of tea stalk is cellulose, seriously affects dark green tea
The color of powder, therefore with selecting Hunan Anhua Dark Green Tea raw material more than region two-stage, detect polyphenol content, testing result such as table
Shown in 1:
The content detection result of tea polyphenols in 1 different stage Dark Green Tea of table
According to the testing result of upper table 1 it is found that polyphenol content highest in superfine Dark Green Tea, and tea stalk is most in superfine Dark Green Tea
It is few, therefore the raw material of dark green tea powder is selected as superfine Dark Green Tea.
Sterling tea polyphenols are white powder, brown are easily oxidized in humid air, tea polyphenols oxidation product is mainly
The substances such as Tea Pigment, Tea Pigment includes the theabrownin of the theaflavin of yellow, red thearubigin and brown, for the mesh for reaching black
, then need for the tea polyphenols in tealeaves to be oxidized to theabrownin, and the higher tea powder color of dark brown cellulose content is deeper.
Related data is looked into, the mode of tea polyphenols oxidation has chemical oxidization method, enzymatic oxidation method, high temperature autoxidation method.
Chemical oxidization method is to utilize K3Fe(CN)6、NaHCO3、FeCl3Equal oxidants aoxidize the tea polyphenols in tealeaves, to the greatest extent
Tube reaction process is fast, but chemical oxidation joined inorganic metal ion, and complex in composition in one side tealeaves, inorganic metal ion can
It can react with substance in tealeaves, bring security risk to dark green tea powder, when another aspect industrialized production easily causes environment
Pollution, production cost are expensive.
Enzymatic oxidation method is to be aoxidized tea polyphenols with tealeaves hybrid reaction using polyphenol oxidase, and enzymatic oxidation method is more
Natural method, product yield is higher, almost pollution-free, but enzyme easy in inactivation, and polyphenol oxidase is expensive, production cost
Height, later period also need to find cheap, efficient, stable biocatalyst.
Why using steaming in step (4) of the present invention, that is, use high temperature autoxidation method.Related data shows that tea is more
Phenol has good thermal stability when less than 80 DEG C, has preferable stability at 100 DEG C or so, and it is more to be heated to tea at 140 DEG C
Phenol starts to agglomerate, and physical behavior is substantially change, so the temperature upper limit that 140 DEG C are stabilized by many data as tea polyphenols.
And the loss late of tea polyphenols is also with heating time there are positively related relationship, the tea that experiment shows to heat after 60min in tealeaves is more
The loss late of phenol respectively be substantially less than heating 90min, 120min, 150min, and heat 90min, 120min, 150min three it
Between tea polyphenols loss late difference it is not significant.The present invention selects high temperature (100 DEG C or more) oxidizing process, is passed through heat in heating
Compressed air makes steamer internal pressure power be maintained at certain level by adjusting air mass flow.To find the optimal oxidation work of tealeaves
Skill selects three related factors to carry out condition test, steams tea temperature (A), steams tea pressure (B), steams between the tea time (C), each factor
Three levels are selected, design orthogonal experiment is as shown in table 2:
2 Three factors-levels orthogonal test of table
Tea optimised process is steamed as a result, determining according to orthogonal test analysis are as follows: steaming tea temperature is 130 DEG C, and steaming tea pressure is 1.5MPa,
It is 120min between the steaming tea time.
Why rotary vacuum dryer is used in step (5) of the present invention, this is because the tea powder after steaming is easy agglomeration,
To improve production efficiency convenient for expanding production, need in the drying process tea powder can be heated evenly, comprehensive current drying machine
Heating method and equipment cost, special to use rotary vacuum dryer, rotary vacuum dryer heating rate is fast, high-efficient, does
The dry period greatly shortens, and energy consumption reduces, and is very suitable to the drying of the heat sensitive material of tea powder etc.
For present invention applicant by inquiry data and experiment discovery, the color of dark green tea is water-soluble and fat-soluble color in tealeaves
The concentrated expression of element, wherein determine tealeaves Appearance color is fat-soluble pigment.Tea color mainly includes color by fresh leaf
Plain (chlorophyll, carrotene, lutein, flavonoids, anthocyanidin etc.) and pigment source substance (polyphenols, carbohydrate, amino
Acid etc.), through oxidation, decomposition, converts, is polymerized.According to the traditional handicraft of current dark green tea, water-removing and pile fermentation form dark green tea
Two most important processes of black color, this process include enzymatic reaction and non-enzymatic oxidation brown stain, because this process include physics,
Chemistry and biological change procedure, process are difficult to regulate and control, thus black level and time bad control for forming tealeaves.I
In practice, it has been found that using Dark Green Tea as raw material, by Dark Green Tea crushing mix it is wet after, the case where steam heats and is passed through air
Under, the high temperature that the substances such as polyphenols, carbohydrate, amino acid in Dark Green Tea can be realized non-enzymatic in the case of a high temperature is automatic
Oxidation, and the theabrownin (TB) of the theaflavin (TF) of yellow, the thearubigin (TR) of brownish red and sepia is gradually formed, with
The raising of temperature and the extension of time, the amount that theabrownin (TB) generates is also increasing, and theabrownin can be with tealeaves at high temperature
Middle others compound such as protein, which combines, forms the dark high polymer for being insoluble in water, this is to form dark green tea shape and tea residue color
Another important coloring matter.We enable to dark green tea powder by control steam heating temperature, steam pressure and duration of ventilation
Color be similar to black.It is formd a kind of with strong after drying aroma-improving by the dark green tea powder that high temperature leads to oxygen production
