Embodiment 1

[0014] In an embodiment of the present invention, a method for extracting organic selenium from rye seedlings consists of the following steps:

[0015] 1) Remove the damaged and mildewed parts of the rye seedlings cultivated with selenium enrichment. After rinsing with clean water, soak in 70% alcohol solution, then drain the alcohol solution on the screen, wash off the alcohol liquid in sterile water, and drain on the screen. Repeat the wash with sterile water to ensure that no alcohol solution remains.

[0016] 2) Divide the washed rye seedlings into 1-2cm segments with a grass cutter, then put them into a juice extractor to extract the juice, and filter the rye seedling juice with a vacuum filter. Then add the same volume of a 1:1 mixture of ethanol and ether to the rye juice after filtering out impurities, heat and stir at high temperature until the mixture of ethanol and ether volatilizes completely, and the heating temperature is 70°C.

[0017] 3) Use a filter pump to ...

Embodiment 2

[0019] In an embodiment of the present invention, a method for extracting organic selenium from rye seedlings consists of the following steps:

[0020] 1) Remove the damaged and mildewed parts of the rye seedlings cultivated with selenium enrichment. After rinsing with clean water, soak in 75% alcohol solution, then drain the alcohol solution on the screen, wash off the alcohol liquid in sterile water, and drain on the screen. Repeat the wash with sterile water to ensure that no alcohol solution remains.

[0021] 2) Divide the washed rye seedlings into 1-2cm segments with a grass cutter, then put them into a juice extractor to extract the juice, and filter the rye seedling juice with a vacuum filter. Then add the same volume of a 1:1 mixture of ethanol and ether to the rye juice after filtering out impurities, heat and stir at high temperature until the mixture of ethanol and ether volatilizes completely, and the heating temperature is 110°C.

Embodiment 3

[0024] In an embodiment of the present invention, a method for extracting organic selenium from rye seedlings consists of the following steps:

[0025] 1) Remove the damaged and mildewed parts of the rye seedlings cultivated with selenium enrichment. After rinsing with clean water, soak in 72% alcohol solution, then drain the alcohol solution on the screen, wash off the alcohol liquid in sterile water, and drain on the screen. Repeat the wash with sterile water to ensure that no alcohol solution remains.

[0026] 2) Divide the washed rye seedlings into 1-2cm segments with a grass cutter, then put them into a juice extractor to extract the juice, and filter the rye seedling juice with a vacuum filter. Then add the same volume of a 1:1 mixture of ethanol and ether to the rye juice after filtering out impurities, heat and stir at high temperature until the mixture of ethanol and ether volatilizes completely, and the heating temperature is 90°C.

Abstract

The invention discloses a method for extracting organic selenium from rye seedlings. The damaged and mildewed parts of the rye seedlings cultivated with enriched selenium are removed; after being washed with clear water, soaked in alcohol, drained and washed with sterile water, they are divided into small sections, Squeeze the juice and filter; then add the same volume of mixed solution composed of 1:1 ethanol and ether to the rye juice after filtering out the impurities, concentrate, precipitate and stand still the solution heated at high temperature; collect it with a filter The precipitated substance is then washed with absolute ethanol, acetone, and anhydrous ether successively, and the cleaned product is quickly transferred to a vacuum dryer equipped with phosphorus pentoxide / sodium hydroxide to dry under reduced pressure; Get the finished product. The finished product obtained by the present invention is rich in organic selenium, which has no toxic and side effects on the human body. After testing, the organic selenium content of the product is 936 mg / kg; it can be safely absorbed by the human body in large quantities, thereby solving the problem that the low selenium content of natural food causes common selenium in the crowd. There is a problem of selenium deficiency.

Description

technical field [0001] The invention relates to a biological extraction technology, in particular to a method for extracting organic selenium from rye seedlings. Background technique [0002] Selenium is an essential trace mineral nutrient for the human body. Selenium was considered to be a toxic trace element in the past, but it is now proven to be an indispensable element for the human body. Both selenium and vitamin E are antioxidant substances, and it has also been proved that it has a therapeutic effect on malnourished children caused by lack of protein, and has a resistance to some possible carcinogens. People with mild or moderate selenium deficiency have no obvious signs or symptoms. Possible diseases caused by selenium deficiency in human body: energy deficiency malnutrition, hemolytic anemia, Keshan disease, Kashin-Beck disease, hypertension, ischemic heart disease, liver cirrhosis, pancreatitis, fibroid, cancer, fibroid, infertility disease, diabetes, cataract,...
