Abstract

The invention belongs to field of health-care tea, provide a kind of selenium-rich health care tea, it is that the fertilizer that will be enriched in organic selenium and sodium selenite solution carry out fertilising cultivation to tea seedling, growing up into the tealeaves that the fresh tea leaf that tree is picked is spread, finished, obtained after drying and processing after tea seedling is Se rich tea.Pass through the fertilising of tealeaves organic selenium, it is more healthy and safe to human body intake selenium in this way, specifically, the booth green time shortens, it can be avoided the green overlong time in booth, water loss in tealeaves is excessive, tealeaves is easy to be rubbed broken during subsequent water-removing, during shaping and drying, control is in reasonable temperature, being able to maintain tealeaves in this way should not be dried, the tealeaves mutability dried is broken, simultaneously, nutritional ingredient in tealeaves not easily runs off, the Se rich tea of the preparation method preparation of the Se rich tea provided through the invention, the loss of the selenium element in tealeaves can be reduced, greatly reduce the turnover rate of selenium.

Description

A kind of selenium-rich health care tea

Technical field

The invention belongs to field of health-care tea, are related to a kind of selenium-rich health care tea.

Background technique

Selenium is one of microelement in needed by human 14, and is the most important special effect microelement of life, is human body The bodyguard of health, is the jinx of cancer, is the patron saint of cardiovascular and cerebrovascular.There are 72% soil all selenium deficiency of 24 provinces and cities in China Or serious selenium deficiency, so daily 4-6 microgram selenium, the only World Health Organization, U.S.'s food can only be taken in driven vegetable food product The 1/10-1/42 of selenium-supply 200-250 microgram for each person every day as defined in product and Drug Administration and the preventive medicine academy of sciences of China. Global 300 multidigits biology, medical expert's research think that human body selenium deficiency can induce various cancers, cardiovascular and cerebrovascular disease, diabetes. More than the 40 kinds of diseases such as hepatopathy, asthma, rheumatic arthritis, pulmonary heart disease, teenager's amblyopia myopia, senile cataract and dementia. Selenium can improve the immunity of the human body and to the resistance of disease.Selenium can prevent cancer cell hyperplasia and diffusion, and anticancer effect is significant, according to beauty The research conclusion of state, daily 200 microgram of Selenium Supplement of the people in selenium deficiency area, lung cancer, prostate cancer, colon and rectum carcinoma hair Sick rate reduces by 50% or more.U.S. clinical trial proves that the prostate-cancer incidence decline 63% after selenium-supply, colon cancer reduces 58%, lung cancer decline 46%.Qidong county of Jiangsu Province of China is High Phc Incidence Area, but whole county whole people's selenium-supply is after 4 years, onset of liver cancer rate Reduce by 50%.American cancer expert points out that appropriate Selenium Supplement can almost prevent all cancers, and the World Health Organization also once announced, selenium Anticancer is beyond the question.There are mainly two types of methods for China's whole people's selenium-supply, first is that mending organic selenium, the se use efficiency such as selenium yeast is high, but It is expensive；Second is that inorganic selenium forms the organic of selenocystein after entering animal and plant body by using Se-rich farm products selenium-supply Selenium, but organic selenium and inorganic selenium is 70%-80% to the absorptivity of human body.In order to prevent and treat 40 kinds of chronic diseases, reduce it is personal and National healthcare takes burden, therefore, a variety of high selenium low price and convenient Se-rich farm products is actively developed and develops, not only for the whole people Selenium-supply, but also can export, because Se-rich farm products are classified as the second largest export food by China.

Summary of the invention

The object of the present invention is to provide a kind of selenium-rich health care teas.The invention is realized by the following technical scheme: Yi Zhongfu Selenium health protection tea is that the fertilizer that will be enriched in organic selenium and sodium selenite solution carry out fertilising cultivation to tea seedling, grows up to tea seedling It is Se rich tea at the tealeaves that the fresh tea leaf of tree picking is spread, finished, obtained after drying and processing.The selenium-enriched health care The preparation method of tea, comprising the following steps: picking: picking selenium-enriched tea leaf, uniform in size, disease-free decayed tooth leaf and yellowing tooth leaf；Its Described in selenium-enriched tea leaf be the Spraying Se-fertilizer during plantation Se rich tea, spray 2-3 times weekly, each Spraying Se-fertilizer 6-8g per acre； Booth is green: loosely spreading, spreads thickness 2-4cm, spreading the time is to start within 1-2 hours to send out faint scent to fresh leaf；Water-removing: water-removing temperature Degree is 200-220 DEG C, and the time is 2-3 minutes, weight-loss ratio 40-50%；It is cooling: to be cooled to room temperature；Shaping and drying: screened Drying and moulding after arrangement, 70-80 DEG C of drying temperature, drying time 20-30 minute, water content 8-10%.Beneficial effect of the invention Fruit: by the fertilising of tealeaves organic selenium, more healthy and safe to human body intake selenium in this way, specifically, the time for spreading out blueness is shortened, energy It enough avoids spreading out green overlong time, the water loss in tealeaves is excessive, and tealeaves is easy to be rubbed broken during subsequent water-removing, whole During shape is dry, control in reasonable temperature, being able to maintain tealeaves in this way should not be dried, and the tealeaves mutability dried is broken, Meanwhile the nutritional ingredient in tealeaves not easily runs off, the Se rich tea of the preparation method preparation of the Se rich tea provided through the invention, energy The loss for enough reducing the selenium element in tealeaves, greatly reduces the turnover rate of selenium.
