Abstract
The present invention relates to a kind of selenium-enriched nano tea and its processing method, the fresh tea leaf just plucked is raw material, and by sterilize, growing dim, charcoal the step such as bakes and prepare Se rich tea, then Se rich tea crushing is prepared into selenium-enriched nano tea powder.The present invention uses Selenium-enriched fermentation bacterium fermented tea, obtains Se rich tea, and human body selenium element required daily can be supplemented after drinking, and production cost is low, is more suitable for industrialized production.
Description
Technical field
The present invention relates to tea manufacture field, more particularly to a kind of selenium-enriched nano tea and its processing method.
Background technology
Selenium is the essential trace elements of the human body.Selenium participates in a variety of selenoenzymes and Selenonic protein in synthesized human.Wherein paddy Guang
Sweet peptide peroxidase, is catalyzed hydroperoxides in vivo or MDA is changed into water or various alcohols, eliminates
Attack of the free radical to biomembrane, protects biomembrane from oxidative damage；Selenium can improve human immunity, promote the increasing of lymphocyte
Grow and antibody and immunoglobulin synthesis.Selenium has obvious to kinds cancers such as colon cancer, cutaneum carcinoma, liver cancer, breast cancer
Suppress and protection effect, its mesostate methyl enol in body has stronger active anticancer.Selenium has simultaneously
Play the role of to mitigate and alleviate heavy metal toxicity.
Coronoid process dissipate capsule bacterium, the past only just found once in a while on ganoderma lucidum in thousand, the especially Fu in the black tea in Hunan Anhua
Grown and its dense in brick tea, this is the exclusive prebiotic strain of Hunan Anhua black tea, also cry overlord bacterium, this bacterium can be effective
Suppress intestinal cancer, stomach cancer, the diffusion of liver cancer cells.Under high magnified glass, ' golden flower ' is in golden yellow, for example spherical mushroom of shape, greatly
Quantifier elimination and clinical data show that effect of coronoid process dissipate capsule bacterium and lucidum spore powder in thousand are very similar, can be effective
Human immunological competence is lifted, anti-cancer, anticancer, anti-oxidant, anti-aging make us promoting longevity, in addition, effect of fat-eliminating slimming is much
Surmount other any strains.
Small molecule Organic Selenium and inorganic selenium and selenoprotein in Se rich tea can effectively supplement the selenium element of human body urgent need, but rich
The selenium element that the conventional infusion method of selenium tea only has 10% enters millet paste.If by selenium content 3-5ppm, daily 5-6 grams of Se rich tea of drink,
2-3 microgram selenium elements can be only supplemented, the daily magnitude of recruitment standard 50-200 micrograms advised far below the World Health Organization, Er Qielang
90% precious Se rich tea product are taken.The nanometer tea prepared using nanometer technology, can effectively discharge whole elite of tealeaves, from
And strengthen viral adsorption, free radical, cholesterol, blood fat of tea etc. and through the effect for killing viral germ, reach good benefit
Selenium effect.
A kind of manufacture crafts of Se rich tea of Chinese patent ZL201310297118.0, are described by spraying coronoid process dissipate capsule bacterium
Conidia powder, the sodium selenite being sprayed on tealeaves changes into Organic Selenium, the technique grow dim prepares Se rich tea, behaviour
Make simple and easy to apply, but by the approach of sprinkling, sodium selenite solution can not be abundant with coronoid process dissipate capsule bacterium conidia powder on tealeaves
Contact, reduces the conversion ratio of Organic Selenium so that the bioavailability reduction of selenium, wastes raw material.
The disclosure of background above technology contents is only used for inventive concept and the technical scheme that auxiliary understands the present invention, and it is not

2nd, clinical practice
1. the toxicity research of selenium-enriched nano tea
1.1 test specimen
Selenium-enriched nano tea granularity：Average 150nm
1.2 experimental animal
Big white mouse, body weight 150-170g or so, male and female half and half, Nanning animal feeding center is provided
1.3 test method
Selenium-enriched nano tea every bag of 5g of maximum, once a bag, three times per day, is calculated by body weight 50kg for each person, equivalent to
Each 0.1g/kg.This is tested to 10 times that the consumption of big white mouse is human body, i.e. 0.1g/100g, after being diluted with a small amount of water, to big
White mouse gavage, separately sets control group, to isometric drinking water, every group of male and female 8.Daily gavage three times, other feed for nursing
As usual carry out, altogether gavage 6 weeks.A body weight is measured every two weeks, observes animal feelings such as activity, hair color, excrement in process of the test
Condition is simultaneously recorded to abnormal conditions.Blood sampling survey blood routine (knit by leukocyte count, red blood cell number, platelet count, net during off-test
Red blood cell number, content of hemoglobin), renal function (urea nitrogen), liver function (total protein, albumin, GPT, TTT)
1.4 result of the tests are with discussing
During 6 weeks feed, the average day's expenditure of feed is 13 ± 2g/, and per day amount of drinking water is 35 ± 5ml/, and category is just
Normal scope；Each group changes of weight increases without significant difference, category normal type.Situations such as big white mouse activity, hair color, excrement, is as good as
Often change, refers to table 1.
Selenium-enriched nano tea also has no significant effect to the blood routine of big white mouse, within normal physiologic range, refers to table 2.
Selenium-enriched nano tea also has no significant effect to Liver and kidney function, within normal physiologic range, refers to table 3.
Thus, selenium-enriched nano tea was drunk in people under conditions of 10 times of amounts, to big white mouse gavage 6 weeks, diet to big white mouse,
Body weight increase, blood routine, liver and renal function have no significant effect.
Selenium-enriched nano tea is absorbed by stomach, improves tea component dissolution rate and bioavilability, pollution-free during processing,
Denaturation, it is ensured that its security；Se rich tea day the amount of drinking everyone be less than 15g, contain according to the selenium of selenium-enriched nano tea of the present invention
Measure 0.35mg/kg to calculate, be 52.5 micrograms per day for human beings selenium-supply amount, the nutrition selenium supplement standard that the World Health Organization proposes is 50-
250 micrograms, if selenium-enriched nano tea all soaks out selenium with water, relatively low selenium-supply amount, will not cause selenosis in being also.
The each group big white mouse changes of weight situation of table 1
The each group big white mouse blood routine of table 2
The each group big white mouse Liver and kidney function of table 3
