(2) the method absorbs inorganic selenium in the secondary biological growth process, converts the inorganic selenium into organic selenium through the photosynthesis of plant growth, degrades and ferments the prepared malt selenium through edible beneficial fungus microorganisms to serve as third biological conversion, so that the content of the organic selenium is further improved, the residue of the inorganic selenium is reduced, and the proportion of the organic selenium in the selenium-rich malt to the total selenium is improved by about 6 percent;
(3) because the invention has two times of conversion than the original technology, the total selenium content of the germinated selenium can be greatly improved, and finally the selenium-rich malt produced by the method provided by the invention can reach more than 450 mg/kg;
(4) the organic components in the selenium-rich malt after fermentation and degradation are changed, the quality is better, and the absorption rate of the selenium-rich malt after being taken by a human body is improved.
Detailed Description
The application principle, action and efficacy of the present invention are illustrated by the following embodiments.
Example 1
A method for producing selenium-rich malt flour comprises the following steps
(1) Planting selenium-rich wheat, spraying selenium-rich water with the concentration of 20mg/Kg one week before wheat flowers, wherein the spraying amount is 40-50 Kg/mu, and harvesting the selenium-rich wheat with the selenium content of 80-300 ug/Kg;
(2) germinating selenium-rich wheat, namely soaking the selenium-rich wheat in 180mg/Kg of selenium-rich water of 100-;
(3) fermenting and degrading beneficial bacteria, cleaning and pulping fermented malt, adding edible beneficial bacteria, stirring uniformly, wherein the adding amount of the beneficial bacteria accounts for 5-10 per mill of the mass of the selenium-rich malt slurry, placing the mixture in a fermentation chamber for fermenting and degrading for 24 hours, the temperature in the fermentation chamber is 28-35 ℃, after the fermentation is finished, drying the selenium-rich malt slurry in a vacuum drying mode at 30-40 ℃, and finally powdering the dried selenium-rich malt slurry to obtain the selenium-rich malt powder.
In the embodiment, selenium-rich water is sprayed in a common wheat planting stage, the tolerance of selenium-rich wheat to selenium in a germination stage is improved, the germination process is not damaged by high-concentration selenium water for soaking and irrigating, the selenium-rich wheat can germinate in high-concentration selenium-rich water environment of 100 plus 180mg/kg, inorganic selenium is absorbed in a secondary biological growth process, the inorganic selenium is converted into organic selenium through plant growth photosynthesis, and the prepared malt selenium is degraded and fermented by edible beneficial bacteria microorganisms to serve as third biological conversion, so that the content of the organic selenium is further improved and the residual inorganic selenium is reduced, and the proportion of the organic selenium in the selenium-rich malt accounts for the total selenium is improved by about 6 percent; because the invention has two times of conversion than the original technology, the total selenium content of the germinated selenium can be greatly improved, and finally the selenium-rich malt produced by the method provided by the invention can reach more than 450 mg/kg; the organic components in the selenium-rich malt after fermentation and degradation are changed, the quality is better, and the absorption rate of the selenium-rich malt after being taken by a human body is improved.
In the embodiment, the selenium-rich wheat obtained in the step (1) can be used for seed production to culture second-generation or even multi-generation selenium-rich wheat, and the tolerance performance of the multi-generation selenium-rich wheat to selenium is gradually increased.
Example 2
A test for comparing the germination conditions of the selenium-rich wheat and the common wheat in 100-180mg/Kg selenium-rich water:
a, B, C three groups of comparison tests are set, wherein the A group of tests adopt 100 grains of selenium-enriched wheat planted in the step (1) of the method, the B group of tests adopt 100 grains of wheat planted after the method of the invention reduces the selenium-enriched water to 2mg/Kg, and the C group of tests adopt 100 grains of common wheat.
A, B, C three groups of wheat are respectively placed in 100-180mg/Kg selenium-enriched water for soaking and then boxed into a germination box, the temperature in the germination box is kept at 20-26 ℃, and germination accelerating and germination are carried out, and the germination conditions are shown in Table 1:
TABLE 1 germination of three groups of wheat
| Time of day | Germination amount of group A | Germination amount of group B | Germination amount of group C |
| 3 days | 20 | 2 | 0 |
| 4 days | 47 | 10 | 1 |
