Description
Technical field
The present invention relates to crop planting processing technique field, specially a kind of method for producing selenium-rich rice.
Background technique
Rice is the staple food crop in China, and the whole nation accounts for about the 50% of total number of people by the population of staple food of rice.I
For state's Monitoring of Paddy Rice Plant Area up to 29,960,000 hectares, distributed areas are vast.Due to the historical reasons such as pressure, China's Rice Production mistake
It goes using high yield as target, it is lower to the attention degree of rice secondary element content, with the increasingly raising of Living consumption and right
The rich trace elements technological development of the development of outer trade, rice will will receive more attention.
Selenium in agricultural product is totally divided into inorganic selenium and organic selenium two major classes: the former includes selenate, selenite etc., nothing
Machine selenium assimilation effect for humans and animals is poor, and risk of toxicity is big, and improper use easily causes selenosis；The latter mainly includes
The forms such as seleno-amino acids, selenoprotein, selenium polysaccharide, the good absorption effect for humans and animals, small toxicity are more suitable for selenium-supply
It is required that.
Due to the food species multiplicity that people daily intakes, select a kind of suitable rice of selenium content extremely important.Mesh
Before, each State Scientific and Technological Commission of country has paid attention to, selenium-rich product and high selenium product are widelyd popularize, and current rice selenium content is relatively low, even if
The intake demand of selenium content can not be met by supplementing other foods；Meanwhile also none more satisfactory, mature selenium-rich rice
Plantation processing method relevant report and patent document etc., therefore, exploratory development goes out a kind of reasonable selenium-rich rice
Implantation methods are necessary.
Summary of the invention
For the above-mentioned problems in the prior art, the present invention proposes a kind of method for producing selenium-rich rice, Ke Yi great
