Abstract

The invention relates to a culture method of selenium-rich soybean sprouts. Soybean seeds are soaked in glycine nanometer selenium solution with the selenium content being 1 to 10mg/L at 30 to 35 DEG C for 24 to 48 hours for pregermination, the germination growth is carried out at 20 to 25 DEG C, in addition, the glycine nanometer selenium solution with the selenium content being 1 to 10mg/L is sprayed once every four hours in the germination process, 8 to 10cm sprouts are grown after 5 to 6 days, the sprouts are taken out and are flushed to be clean, the selenium-rich soybean sprouts are obtained, the selenium content is 1 to 1.2mg/kg, and inorganic selenate and selenite are not contained. The method provided by the invention has the advantages that the selenium content of the glycine nanometer selenium solution is changed, so the selenium-rich soybean sprouts with different selenium contents can be cultured, and rich-nutrition delicious high-quality selenium supplementing food is provided for people.

Description

The cultivating method of the big bean sprouts of a kind of rich selenium

Technical field

The invention belongs to the cultivating method of the big bean sprouts of a kind of rich selenium.

Background technology

Selenium is one of 14 kinds of trace elements of needed by human, is multi-functional life nutrient, has many-sided physiological function, and selenium can effectively be removed free radical; Anti-oxidant, suppress the generation of lipid peroxide, regulate immunologic function, the enhancing body resistance; Prevent blood clot, remove cholesterol, have the effect identical with insulin; Can obviously promote the ability of cellular uptake sugar, stimulate circulation, prevent skin aging; It is carcinous to reduce luring of carcinogen, and the cancer cell of eliminating vivo mutations forms, and stops cancer cell division, growth.If the body short-term lacks selenium, frequent flu can appear, hypoimmunity, canker sore is shown effect repeatedly, pachylosis, wrinkle increases, and presents age mark, chloasma, insomnia, dizziness, chest distress and palpitation symptoms, sleepy weak etc.If lack selenium for a long time then easy Keshan disease, the Kaschin-Beck disease of causing, initiation tumour, hepatopathy, cardiovascular and cerebrovascular disease, diabetes etc.Along with medical science to the more deep understanding of the physiological science of selenium, the power of selenium more and more is familiar with by people.

Yet the content of selenium in the earth's crust is very rare, and it is extremely uneven to distribute again; Announce that according to WHO the whole world has more than 40 country to belong to low selenium and scarce selenium area, China is a scarce selenium big country; Investigation shows; Except indivedual counties, Ziyang, Shaanxi and enshi city are the high selenium area, 72% county (city) belongs to low selenium and scarce selenium area, and atmosphere and industrial pollution are constantly destroying plant absorbing selenium again.Be grown up and need take in 50 micrograms normal every day, the exhausted most area of China surpasses the selenium wretched insufficiency that 700,000,000 populations obtain from food, and therefore, it is very urgent to mend selenium in safety and suitable scope clinical practice.

Big bean sprouts is the traditional bean product of China, is a kind of vegetables of nutritious, delicious flavour.In soya bean seed-soaking and germinating growth process shower water, add an amount of selenium element that contains, transform through the bio-absorbable enrichment and produce the big bean sprouts of rich selenium, for people provide a kind of nutritious, the benefit selenium food of delicious flavour.

Existing technology of producing the big bean sprouts of rich selenium, mung bean sprouts all is to be employed in seed soaking and the shower water to add sodium selenite, residual inevitably 30-40% inorganic selenium in the total selenium amount of producing in the big bean sprouts of rich selenium.

Inorganic selenium such as sodium selenate, sodium selenite is once as oral drugs and the functional health-care food of mending selenium, but the physiologically active of such inorganic selenium is low, also has certain toxic and side effect, seldom uses at present.

Summary of the invention

The cultivating method that the purpose of this invention is to provide the big bean sprouts of a kind of rich selenium overcomes the deficiency of prior art, and a kind of big bean sprouts of rich selenium cultivating method that does not contain residual inorganic sodium selenite is provided.

The present invention includes following steps:

1. the preparation of glycine nano selenium solution:

The glycine nano-selenium 1-10 gram that takes by weighing selenium content 10000mg/kg is dissolved in the 10L water, is prepared into selenium content 1-10mg/L glycine nano selenium solution;

2. take by weighing soya bean seed 1kg, input fills in the container of 3L water, and the epidermis of stirring and washing soya bean seed drags for the inferior beans of keeping afloat, the elimination wash water, more once with the drinking pure water flushing;

3. the soya bean seed that will clean is put into and is filled 30-35 ℃ of 5-6L selenium content 1-10mg/L glycine nano selenium solution, and presoaking and germinating 24-48 hour, soya bean seed absorbent solution, volume expands, and plumule is sprouted;

4. pull the soya bean seed after immersion, the vernalization out, put into basin with holes or basket, keep 20-25 ℃ of germination of indoor temperature; Whenever with selenium content 5-10mg/L glycine nano-selenium solution spraying once, consumption 500ml was through 5-6 days germinating growths in germination process at a distance from 4 hours; The bud seedling is long to 8-10 centimetre; Rinse well with running water and to obtain the big bean sprouts of rich selenium, selenium content 1-1.2mg/kg does not contain inorganic selenite.Change the selenium content of glycine nano selenium solution, can nurture the big bean sprouts of rich selenium of different selenium contents.

The selenium content that the present invention changes the glycine nano selenium solution can nurture the big bean sprouts of rich selenium of different selenium contents, and for people provide a kind of nutritious, the high-quality of delicious flavour is mended selenium food.

Embodiment

The present invention adopted glycine nano-selenium solution soaking soya bean seed 24-48 hour; And in soya bean seed sprouting process whenever at a distance from 4 hours with glycine nano-selenium solution spraying 1 time; Grow up to 8-10 centimetre the big bean sprouts of rich selenium after 5-6 days; Selenium content 1-1.2mg/L does not contain sodium selenite, and edible 50-100 gram can reach the effect of mending selenium 50-100 microgram.

Glycine nano-selenium is to be to modify the compound that carrier is wrapped in the surface formation stable in properties of red nano selenium with the glycine; Nanometer selenium is a zeroth order selenium; Can be by biological and absorption of human body utilization, bring into play the health cares such as biological action and anti-oxidant, immunological regulation of selenium, inorganicly compare with other with organic selenium compounds; Biggest advantage is that toxicity is low, and is safe.
