Embodiment 1

[0018] A production method of selenium-enriched malt powder includes the following steps

[0019] (1) Planting selenium-enriched wheat, spraying selenium-enriched water with a concentration of 20mg / Kg a week before the wheat blooming, the spraying rate is 40-50Kg / mu, and harvesting selenium-enriched wheat with 80-300ug / Kg selenium;

[0020] (2) Germination of selenium-enriched wheat, soak the selenium-enriched wheat in 100-180mg / Kg selenium-enriched water and then pack it into the germination box, keep the temperature in the germination box at 20-26℃, and carry out germination and germination without interruption Supplement water with selenium-enriched water until the wheat germinates, and obtain selenium-enriched malt with selenium content of 260-450mg / Kg after drying;

[0021] (3) The beneficial bacteria are fermented and degraded. After the malt is washed and pulped, the edible beneficial bacteria are added and mixed evenly. The added amount of beneficial bacteria accounts for 5-1...

Embodiment 2

[0025] For the experiment of comparing the germination of selenium-enriched wheat and ordinary wheat in 100-180mg / Kg selenium-enriched water:

[0026] Set up three groups of comparative tests A, B, and C. Group A uses 100 selenium-enriched wheat grown in step (1) of the method of the present invention, and Group B uses the method of the present invention and reduces the selenium-rich water to 2mg / Kg. 100 grains of wheat were produced, and 100 grains of ordinary wheat were used in the C group test.

[0027] Put the three groups of wheat A, B, and C into the germination box after soaking in 100-180mg / Kg selenium-enriched water. Keep the temperature in the germination box at 20-26℃, and perform germination, germination, and seed germination. The situation is shown in Table 1:

[0029] time Germination amount of group A Germination amount of group B Germination amount of group C 3 days2020 4 days47101 5 days89121 10 ...

Embodiment 3

[0032] Verification test for step (3) whether to reduce the residual inorganic selenium:

[0033] Set up D and E two groups of control experiments. In the D group experiment, 1g of the malt powder before fermentation of the present invention was used, and the E group experiment used the malt powder obtained after fermentation of the same batch of 1g malt powder.

[0034] Divide the malt powder in the D and E two groups into 5 parts, and fully dissolve them in 10 mL of water. After standing for 1 day, use 2 mL of the supernatant to test inorganic selenium. The experimental data obtained after the test are shown in Table 2. :

[0035] Table 2 The inorganic selenium residues in the supernatants of the two groups D and E

[0036]

[0037] It can be seen from Table 2 that the residual amount of inorganic selenium in the supernatant of the E group is far lower than that of the D group. Step (3) of the present invention can indeed further increase the content of organic selenium and reduce t...

Abstract

The invention discloses a production method of selenium-enriched malt flour and relates to the technical field of selenium-enriched treatment. The production method comprises the following steps: (1) planting selenium-enriched wheat: spraying selenium-enriched water, concentration of which is 20mg / Kg, before flowering of wheat, wherein the spray amount is 40-50Kg / mu, and harvesting selenium-enriched wheat, the selenium content of which is 80-300 micro-gramme / Kg; (2) germinating the selenium-enriched wheat: immersing the selenium-enriched wheat in 100-180mg / Kg selenium-enriched water, casing the selenium-enriched wheat in a germinating box, keeping the temperature in the germinating box at 20-26 DEG C for accelerating germination and sprouting, and continuously supplementing the selenium-enrich water till the wheat germinates, and drying the wheat to obtain the selenium-enriched malt, the selenium content of which is 260-450mg / Kg; and (3) fermentation and degradation of beneficial bacteria: cleaning and pulping the malt adding edible beneficial bacteria to uniformly stir, putting the mixture in a fermenting chamber for fermentation and degradation for 24 hours, wherein the temperature in the fermenting chamber is 28-35 DEG C, after fermentation, drying the selenium-enriched malt slurry by way of vacuum drying at 30-40 DEG C, and finally, powdering the dried selenium-enriched malt slurry to prepare the selenium-enriched malt flour.

Description

Technical field [0001] The invention relates to the technical field of selenium-enriched treatment, and more specifically to a method for producing selenium-enriched malt powder. Background technique [0002] Generally, the addition of selenium in the selenium-enriched malt is carried out during the germination of the wheat. The specific method is: soaking and spraying the wheat with sodium selenite solution, and then washing and drying the wheat after germination. [0003] However, this treatment method has the following technical problems: Generally, the selenium content of selenium-enriched malt is about tens to 100 mg per kilogram, and it is not easy to make products with high selenium content; the test shows that the selenium-enriched malt contains In the amount of selenium, there is more residual inorganic selenium; inorganic selenium has greater toxicity, and it is easy to cause poisoning reactions when eaten. Summary of the invention [0004] The invention provides a produc...
