Description

Selenium-rich grape and production method thereof

Technical field

The present invention relates to fruit, especially a kind of selenium-rich grape and production method thereof.

Background technology

The selenium trace element of dominating life that to be Sweden chemist Bei Cailiwusi found in 1818, its physicochemical characteristics between metal and nonmetal between, the content in the earth's crust only is 1/100000000th.Since how many centuries, the mankind are not familiar with selenium, more do not know to lack selenium and can make the people sick.Disease is being tangled the mankind just as ghost, makes the people ill unclearly, can not find reason, more can not find good recipe.Through the exploration of scientists over half a century, the mankind just have been familiar with selenium gradually, and selenium is described as " life kindling material ", " anticancer king ", " cytoprotection god ", " natural antipoison ".

Selenium is 1/10000000th at the tissue intensive amount, but it has determined the existence of life, and it but is that other materials can't substitute to the huge effect of human health.Scarce selenium can directly cause the human immunological competence to descend, clinical medicine proves, it is relevant that more than the 40 kind of disease that threatens human health and life and human body lack selenium, as cancer, cardiovascular disease, hepatopathy, asthma, cataract, pancreas disease, diabetes, genital system diseases, child development is bad and nutrition is blocked or the like.Life Science and Technology research institute of Hunan University doctor Xiao Suyao says, the whole world has more than 40 countries and regions to belong to scarce selenium area, China is exactly a scarce selenium big country, discloses according to " place of china sick with environment atlas ", and about 700,000,000 people live in the low selenium area that accounts for China's area 72%.Children ' s lead poisoning particularly, selenium is the natural antipoison of poisonous heavy metal element such as lead, cadmium.The investigation to 28 provinces and cities in the whole nation in 1998 of China Center for Disease Control shows that China's urban children mean lead poisoning rate is 60.5%, is higher than western developed country far away, exceeds more than 50 times than the U.S..Studies show that children blood lead levels increases by 10 micrograms for every liter, causes IQ to be lost nearly one minute, height reduces by 0.13 centimetre.And in view of this, domestic at the turn of the century a collection of environmental medicine expert just predicts: " if or else carry out effective lead pollution control, after 20 years, the whole children's of the Chinese nation IQ will be than U.S. children low 20%.”

This shows that selenium and health are closely bound up, it is to dominate the important trace element of human life, and this point has become countries in the world scientist's common recognition.

1973, the World Health Organization announced that to the whole world selenium is trace element essential in the humans and animals vital movement.The unusual effect of selenium causes a sensation in developed country immediately, the American of consistent attention health is after WHA finishes, just start everybody in the whole nation and mended the upsurge of selenium, various selenium-enriched foods U.S. of from then on selling well, 1974, U.S. official mission food and administration of health office expressly provided, for the guarantor can obtain enough selenium, in the feed of edible animal, must add a certain amount of selenium.After this twice expansion and improved the interpolation scope and the dosage of selenium again of 1989 U.S. officials, and people's daily intake is decided to be 200 micrograms.The famous scientist of the U.S., lifetime professor doctor Ke Musi of Cornell University passes through 3000 Americans, the benefit selenium clinical trial that lasts 13 years, draw such conclusion at last, quantitatively mend selenium and can reduce cancer morbidity more than 50%, the researcher who reaches Thomas medical university of the U.S. finds that selenium has the effect that prolongs human longevity simultaneously.Chinese science man investigation finds that centenarian's selenium level is 3～6 times of common people.The seventies, it is relevant that the Keshan disease research worker of China finds that Keshan disease and crowd are in scarce selenium state, and benefit selenium can effectively prevent Keshan disease.On behalf of China, this achievement in research report in second international selenium discussion in 1980, causes the great interest of participant.This achievement becomes human knowledge's selenium and healthy another milestone.

In October, 1988 in " dietary guidelines of nutrient allowance and China in the every day meals " that Chinese Soclety of Nutrition is recommended, selenium has been classified as 15 kinds every day one of diet nutrient.After this, people recognize gradually, should be as absorbing starch, protein every day, and every day also must an amount of selenium of picked-up.

For this reason, Chinese Soclety of Nutrition, China's trace element are raised a cry of warning with healthy association---grab benefit selenium as grabbing to enrich the iodine.

China has 70% the scarce selenium in area approximately, particularly some areas of 15 provinces, cities and autonomous regions from northeast to southwest have constituted " poor selenium area ", also have Soviet Union, Anhui, Shandong, sweet, peaceful etc. economize, the also poor relatively selenium in municipal some areas, under the more underdeveloped state of commodity economy, scarce selenium in the human body is more serious, the task of top priority at present is to carry out two things: the one, and various public opinion medium should be popularized the knowledge of relevant selenium of propaganda and health to the resident, and the resident is improved how preventing to lack the understanding of selenium; The 2nd, start to develop and produce selenium-enriched food, manually add selenium and produce selenium-enriched food.

China scientific circles adopt popular in the world method at present---and " food reinforcement " solves and lacks a selenium difficult problem." food reinforcement " promptly in daily food, adds the nutritive element that human body lacked.This method is simple, and is safe and effective, harmless, and some health products are compared much lower on cost and the market.By the Spraying Se foliage fertilizer,, with the inorganic selenium element absorption and change the organic nutrition selenium element that human body absorbs easily into, the fruits and vegetables selenium content is increased, thereby reach the purpose of mending selenium to human body through the fruits and vegetables food chain by the biological motion of fruit-vegetable plant.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this invention is to provide a kind of selenium-rich grape that can address the above problem and production method thereof.
