Technical field
The present invention relates to a kind of method of quality control of rich selenium cereal, belong to the culture technique field.
Technical background
Selenium is trace element essential in the humans and animals body, is to constitute the nearly activated centre of 23 kinds of functional proteins such as glutathione peroxidase (GSH-Px), selenoprotein P, have anticancer, anti-oxidant, improve effect such as immunity.To the greatest extent China has 72% area day selenium intake significantly to be lower than the selenium daily intaking amount that The World Health Organization (WHO) is recommended approximately, has caused serious human body and animal health problem.
Selenium totally is divided into inorganic selenium and organic selenium two big classes: the former comprises selenate, selenite etc., and inorganic selenium assimilation effect for humans and animals is poor, and risk of toxicity is big, and improper use very easily causes selenosis; The latter mainly is meant the selenium with the biological organic molecule combining form, and the organic selenium absorption ratio is high concerning humans and animals, and risk of toxicity is little, is more suitable for mending the requirement of selenium.The further segmentation of organic selenium mainly comprises selenomethionine, selenocysteine, also is included in all seldom selenium polysaccharides, seleno nucleic acid etc. of content in the animals and plants.And also there is bigger difference in the above two metabolism in the humans and animals body, and main non-specific binding was in proteosome after selenomethionine got into body; Storage might not be brought into play biological function as selenium; Selenocysteine then directly gets in the metabolic pathway of synthesizing of selenoprotein, is its biology merit play a role (progress of yeast organic selenium, Chen Min, Li Feng; Feed research, 2010).
General traditional foliage-spray technology or the comparatively advanced root of adopting of the production that is directed to selenium-enriched crop at present executed technology; But owing to be difficult to guarantee the homogeneity of fertilising in the fertilising process; And many factors such as the landform of the various complicacies in field, soil property, water and fertilizer management and weather; The uniformity and the less stable that cause Se content in the artificial land for growing field crops Se-rich farm products of producing; The Se content that extends in the rich selenium product of deep processing also lacks standardization, brings bigger obstruction for the application and the popularization of technique of enriched selenium, and the product quality behind the rich selenium is stable inadequately.The present invention therefore.
