Description

A kind of lyophilized powder preparation method of white tea

Technical field

The present invention relates to a kind of lyophilized powder preparation method of white tea, the lyophilized powder technology of preparing for belonging to medicament is led Domain.

Background technology

White tea is a kind of slight fermented tea, from the bud-leaf more than pekoe spy, to add without the special fine method for rubbing stir-fry Work forms.The fresh leaf of white tea requires " three is white ", i.e. tender shoots and two panels tender leaf has pekoe to appear；Fine hair is completely draped over one's shoulders into tea, and color is in vain such as Silver, therefore named white tea.White tea is divided into young tea leaves (such as silver tip pekoe) and leaf tea (such as tribute eyebrow) because the standard of tea tree breed, harvesting is different； Use simple bud for thick material be process for young tea leaves, referred to as acupuncture needle；Had using the complete leaf blade back of a bud one or two dense White-colored hairs be process for leaf bud, referred to as white peony；

The effect of white tea, has：

First, promoting blood glucose balance, health protection tea market survey shows, white tea in addition to containing the intrinsic nutritional ingredient of other tealeaves, Also contain organized enzyme necessary to human body, domestic and international medical research proves that internal lipase can be significantly improved by drinking white tea for a long time (lipoproteinlipase) it is active, promote catabolism of fat, effectively control amount of insulin secretion, delay the intestines of grape fruit powder Absorb；

Second, improving eyesight, the white tea resting period is longer, and its medical value is higher.Also containing abundant ProvitaminA, its quilt in white tea After absorption of human body, vitamin a can be quickly converted to, vitamin a can synthesize rhodopsin, and eyes can be made to see thing more under half-light It is clear, yctalopia and scheroma can be prevented.White tea also has radio-opaque substance simultaneously, has significant protection to the hematopoietic function of human body Effect；

Third, the flavonoids natural materials such as liver protecting, the dihydromyricetin that white tea piece is rich in.When Ethanol intake excess, more than people When the metabolic capability and detoxification ability of body liver, alcohol will to liver cell produce directly or indirectly infringement, stimulate Fatty synthesis, Anoxic, produce acetaldehyde and induce each relevant enzyme activity and cause to upset liver metabolism etc.；

Fourth, control measles, white tea anti-cancer, anticancer, heatstroke prevention, detoxify, control toothache, especially old white tea can be used as measly The antipyretic of child, its effect of bringing down a fever are more preferable than antibiotic.Treatment maintenance fiber crops are widely regarded as in North China and the Fujian place of production The good medicine of rash patient.

White tea is primarily as a kind of tea-drinking raw material at present, i.e., by plucking, fresh leaf is processed to be made, basically by bubble Tea is used, and the drink or medicament of patent medicine is manufactured separately in also none of these methods in the prior art, thus can not be improved white The bioactivity of tea, the utilization rate of white tea active ingredient is improved, and improve the active ingredient absorptivity of people's body etc..

The content of the invention

It is an object of the invention to overcome the shortcomings of the prior art, and it is simple to provide a kind of preparation method, can be most The earth ensures the bioactivity of product, improves the utilization rate of active ingredient, and manufactured particle can conveniently brew use, improve body The lyophilized powder preparation method of the white tea of internal absorption factor.

The purpose of the present invention is completed by following technical solution, a kind of lyophilized powder preparation method of white tea, institute The preparation method stated comprises the following steps：

a）Net system, from the fresh tender shoots leaf of plant of theaceae white tea, choose and pick impurity and rotten blade, washed away with drinking water Silt impurity, then use pure water rinse；

b）Water fixing is scalded, with 90-100 DEG C of boiling 2-5 minutes, draining spreading for cooling；

c）Slurrying, slurries are made with beater；

d）Freeze-drying, take out during with freeze drier drying to aqueous less than 6%；

e）Ultralow temperature crushes, and in the environment of subzero 10-30 DEG C, is ground into the superfine powder of 200 mesh；

f）Boiling granulating, make adhesive with fluid bed granulator and with pure water, particle is made in superfine powder.

As preferred：Described step a）, the fresh tender shoots leaf of the white tea harvested from Clear and Bright to grain rains is as raw material；

Described step b）, with 95-100 DEG C of boiling 3-5 minutes, picked up when slightly the intrinsic faint scent of this product overflows, draining Spreading for cooling；

Described step d）, take out during with freeze drier drying to aqueous less than 5%；

Described step e）, in the environment of subzero 20-30 DEG C, it is ground into the superfine powder of 200 mesh.

The present invention has preparation method simple, can maximally ensure the bioactivity of product, improve active ingredient Utilization rate, improves body absorption rate, and manufactured particle can conveniently brew the features such as use.
