Description
Technical field
The present invention relates to a kind of rich selenium product, specifically, the present invention relates to a kind of rice rich in selenium and production method thereof and purposes.
Background technology
Selenium is the essential micronutrient element of humans and animals, it has many important physical functions, the most important thing is that wherein selenium form with selenocysteine (SeCys) in human body and animal body participates in constituting glutathione peroxidase (GSH-Px), thereby remove too much active oxygen radical in the body.External source selenium can be induced the increase and the catalatic activity of GSH-Px activity.When body is in when lacking the selenium state, GSH-Px is active to be reduced, and causes the accumulation of lipid free radical and peroxide, thereby might bring out unusual lipid peroxidation (LPO), causes that cell membrane destroys, tissue damage, and tumour takes place.Discover, in certain selenium concentration scope, the content of selenium and being proportionate property of GSH-Px activity.Proofs such as Huang Yimin, the patient who suffers from atrial septum and ventricular septal defect takes selenium can reduce malonaldehyde (MDA, the end product of a kind of LPO, poisonous) level, improves the GSH-Px activity, and keeps mobility of erythrocyte membrance preferably.Reports such as Xue Tailin, SeCys have the ultra-oxygen anion free radical of removing and hydroxy radical under high concentration, the effect of protection cell membrane.Selenium can improve body immunity, and its effect relates to humoral immunity and cellular immunity.Body lacks selenium, can cause the pancreas islet infringement that B cell mechanism and dysfunction cause, the lymphoid organ short texture that becomes, phagocyte, lymphocyte number reduce, the desmacyte hyperplasia causes the primary lesion of exocrine function, and immunocompetence is suppressed or fails.Mend selenium to animal and can improve the antigen titration degree of animal, reduce the immunity time, promote the synthetic of animal's antibody and immunoglobulin red cell antigens or tetanus toxoid.Selenium can be eliminated the accumulation of heavy metal of body, has the ability of removing heavy metal poisoning, is the natural antipoison of part heavy metal element (as mercury, cadmium, lead etc.); In addition, selenium can influence the metabolism of liver blood red pigment, reduces the toxicity of aflatoxin B1.Body lacks the generation that selenium will cause a series of diseases, as Keshan disease, Kaschin-Beck disease etc.Body is mended selenium can reach anti-cancer, anticancer purpose.The incidence of disease of selenium and human multiple cancer is negative correlation, and can prevent significantly and suppress the tumour that spontaneity, transplantability and the chemical carcinogens of animal bring out generation, develop, disseminate and recur.Selenium plays an important role to angiocardiopathy preventing, helps keeping normal structure of cardiovascular system and function, and the appearance of prevention of arterial sclerosis and coronary heart disease can be kept the normal arterial pressure of body.
According to World Health Organization's data, usually man every day minimumly should take in 34 microgram selenium, adult women every day is minimum should take in 26 microgram selenium, and pregnant woman every day is minimum should take in 28～42 microgram selenium, and children every day is minimum should take in 17～21 microgram selenium.In general, the adult should take in 50 micrograms every day or above selenium could satisfy the Human Physiology requirement.Become the selenium total amount that contains in the human body to be generally about 13 milligrams, muscle accounts for 35%, accounts for 8.5% in the blood.By metabolism, nearly 50% excretes in 30 days behind the absorption of human body selenium.It is 60～152 micrograms/kilogram food that every day is taken the photograph the selenium amount per capita by the U.S., it is 98～222 micrograms/kilogram food that every day is taken the photograph the selenium amount per capita by Canada, it is 88 micrograms/kilogram food that every day is taken the photograph the selenium amount per capita by Japan, it is 21～56 micrograms/kilogram food that every day is taken the photograph the selenium amount per capita by Finland, and it is 30 micrograms/kilogram food that every day is taken the photograph the selenium amount per capita by New Zealand.It is 40～120 micrograms/kilogram food that the selenium amount is taken the photograph in China city per capita every day, and it only is 10～50 micrograms/kilogram food that the selenium amount is taken the photograph in the rural area per capita every day.
China lacks the more serious country of selenium, and the whole nation has 2/3 soil to be in the geochemical environment that lacks selenium or low selenium approximately.In addition, also have very large-area iodine deficiency, lack zinc etc. problem, cause these nutritive element deficiencies in China's meals therefrom, cause the immune function of human body decline and various endemic occur, cardiovascular disease, tumour etc.The content that scientific order ground improves selenium in the Chinese meals, iodine, zinc etc. is the key that fundamentally improves the health of people level, be effectively, measure cheaply.Plant selenium is the main source that the human and animal obtains selenium.In the trophism of selenium, organic selenium is greater than inorganic selenium, and plant selenium is greater than animal selenium.At present, China still can not synthetic plant organic selenium, and the approach that obtains the plant organic selenium relies on the conversion technology of plant mostly, wherein protects to draw together water planting (or soil) and execute selenium or crops spray selenium.Utilize the biological transformation of plant, improving organic selenium content and entering food chain confession humans and animals edible is a main technique of enriched selenium.
The external cultivation method report that does not still have selenium-rich rice, the composition that be unable to do without to use various fertilizers, inorganic fertilizer in the domestic prior art and contain the selenium material comes the cultivation of selenium-rich paddy rice, but owing to composition in the employed composition in the prior art is many, being unfavorable for has remnants after paddy rice fast Absorption and the absorption.
Early stage studies show that, the selenium of minute quantity just can stimulate selenium to gather the growth of plant, and the non-growth of gathering plant of strong inhibition selenium.Under higher concentration, the selenosis symptom appears in most of plant, and growth and physiological activity are suppressed.Therefore, restricted the production of selenium-enriched rice owing to the existence of Se content in the plant corpus and this contradiction of output.
