Embodiment 1

[0018] A method for producing selenium-enriched malt powder, comprising the following steps

[0019] (1) Plant selenium-enriched wheat, spray selenium-enriched water with a concentration of 20mg / Kg one week before the wheat blooms, and the spraying amount is 40-50Kg / mu, and harvest selenium-enriched wheat with a selenium content of 80-300ug / Kg;

[0020] (2) For germination of selenium-enriched wheat, soak the selenium-enriched wheat in 100-180mg / Kg selenium-enriched water and pack it into a germination box, keep the temperature in the germination box at 20-26°C, and carry out accelerated germination and germination without interruption Supplementary irrigation of selenium-enriched water until the wheat germinates, and after drying, selenium-enriched malt with a selenium content of 260-450mg / Kg is obtained;

[0021] (3) Fermentation and degradation of beneficial bacteria. After washing and beating the fermented malt, add edible beneficial bacteria and stir well. The amount of b...

Embodiment 2

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

[0026] Set A, B, C three groups of comparative tests, A group test adopts 100 selenium-enriched wheats planted in the method step (1) of the present invention, B group test adopts the method of the present invention, and reduce the selenium-enriched water to 2mg / Kg after planting 100 grains of wheat were produced, and 100 grains of common wheat were used in group C experiments.

[0027] Soak the wheat in groups A, B, and C respectively in 100-180mg / Kg selenium-enriched water and pack them into germination boxes, keep the temperature in the germination box at 20-26°C, accelerate germination, germinate, and germinate seeds The situation is shown in Table 1:

[0028] Table 1 The germination of three groups of wheat

[0029] time Germination amount of group A Germination amount of group B Germination amount of group C 3 day...

Embodiment 3

[0032] To step (3) whether reduce the verification test that inorganic selenium remains:

[0033] Set D, E two groups of contrast experiments, in D group test, adopt 1g malt powder of the present invention before fermentation, E group test adopt the malt powder obtained after same batch of 1g malt powder fermentation.

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

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

[0036]

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

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, in particular to a production method of selenium-enriched malt powder. Background technique [0002] Generally, the addition of selenium in selenium-enriched malt is carried out in the process of wheat germination. The specific method is: soak the wheat with sodium selenite solution, spray the wheat, and wash and dry the wheat after germination. [0003] However, this processing method has the following technical problems: the selenium content of generally selenium-enriched malt is about tens of milligrams to one hundred milligrams per kilogram of selenium, and it is difficult to make products with high selenium content; In the amount of selenium, there are more inorganic selenium residues; inorganic selenium is highly toxic, and eating can easily cause poisoning reactions. Contents of the invention [0004] The invention provides a production method of selenium-enriched ma...
