Figure BDA0001604461260000061
from table 3, it can be seen that under the same conditions the concentration is 1: the effect of 4000 mixed selenium solution was optimal, group D at a concentration of 1: half rotten malt at 3000 hours; group E1: at 2000, the malt was completely rotten.
Example 4:
this example mainly considers 1: the mixed solution with 5000 concentration is used for seed soaking, under the same condition of 30-50% of humidity, the time required for the malt to grow to 5cm high at different temperatures and the influence of the time on the organic selenium content in the malt solid beverage are as follows:
(1) the barley seeds are divided into 4 groups of A group, B group, C group and D group for testing: the time required for the group A to grow to 5cm high at 38-40 ℃ is 3 days; the time required for the group B to grow to 5cm high at the temperature of 28-30 ℃ is 5 days; the time required for the group C to grow to 5cm high at the temperature of 18-20 ℃ is 10 days; the time required for the group D to grow to 5cm high at 8-10 ℃ is 25 days.
TABLE 3
Figure BDA0001604461260000071
As shown in Table 3, the temperature is controlled to be 18-20 ℃ and the indexes after the malt grows out are the best.
Example 5:
in this example, the influence of the humidity of the malt in a dry state within 5-8% on the content of organic selenium in the malt solid beverage in the drying process at different temperatures of the optimal malt obtained through the above four experiments is examined, and the results are shown in table 4.
Table 4:
Figure BDA0001604461260000072
as can be seen from Table 4, the temperature for drying the barley malt was controlled to 50 ℃ and the organic selenium in the selenium-enriched malt solid beverage was more than 90% of the total selenium content.
In conclusion, the invention converts inorganic selenium into organic selenium through the biological conversion function of barley malt, and simultaneously utilizes the absorption and conversion function of selenium in L-selenium-methyl selenocysteine to promote the sprouting growth process of barley malt, so that selenium is enriched on various amino acids, proteins and the like contained in barley malt, thereby not only increasing the types of nutrient substances such as amino acids containing selenium in barley malt, but also supplementing trace elements required in the growth process of barley malt, improving the absorption and conversion function of the barley malt on inorganic selenium, and having higher content of organic selenium compared with single inorganic selenium or organic selenium.
The above examples are merely illustrative of the present invention and should not be construed as limiting the scope of the invention, which is intended to be covered by the claims and any design similar or equivalent to the scope of the invention.
