Technical Field

The invention relates to a production method for producing milk rich in trace elements, in particular to a production method for selenium-rich milk.

Background

With the rapid development of economy and the improvement of living standard, people put forward higher requirements on the aspects of food diversification and nutrition scientification, and desire to improve the self health level and the life quality by adjusting the dietary structure and supplementing nutrient substances.

Selenium is an essential trace element in animal body, has strong oxidation resistance, is an important component of in vivo antioxidant enzyme glutathione peroxidase (GSH PX), and can improve immunity of organism. Selenium is generally divided into two main categories of inorganic selenium and organic selenium: the former includes selenate, selenite, etc., inorganic selenium has poor absorption effect for human and animals, has large toxicity risk, and is easy to cause selenium poisoning when being used improperly; the latter mainly refers to selenium in a form combined with biological organic molecules, and the organic selenium has high absorptivity and low toxicity risk for people and animals, and is more suitable for the requirement of selenium supplement. The further subdivision of organic selenium mainly comprises selenomethionine and selenocysteine, and also comprises selenium polysaccharide, selenium nucleic acid and the like which are all low in animal and plant contents. The distribution, absorption and metabolism mechanism and biological activity of the above-mentioned plants in the biological organism are greatly different. Selenomethionine in most natural plants occupies the predominant form, such as most cereals of the family gramineae; in minor genera (e.g., Brassicaceae, etc.), selenium is often present in the form of selenocysteine. In the animal metabolism process, selenomethionine enters the selenium circulation system of the body after being converted in the intermediate process, and selenocysteine can directly participate in the selenium circulation of the animal body.

Disclosure of Invention

The invention aims to provide a production method of selenium-enriched milk. The method for producing the selenium-rich milk by using the organic selenium is safer and has better effect.

in order to achieve the purpose, the technical scheme of the invention is as follows:

A method for producing selenium-rich milk comprises culturing selenium-rich wheat seedling, and allowing milk producing animals such as cow or sheep to eat the selenium-rich wheat seedling according to certain amount to produce natural selenium-rich milk; the specific method comprises the following steps:

1. cultivation of selenium-rich wheat seedlings

1) Preparing an organic selenium nutrient solution: preparing a selenium-containing solution with the volume fraction of 0.1-0.6% by using organic selenium;

2) Seed soaking and germination accelerating: soaking the wheat seeds with excellent quality in the organic selenium nutrient solution, wherein the wheat seeds just submerge; after uniformly stirring, accelerating germination at the temperature of 20-25 ℃ and the humidity of 70-80%, and culturing for 3-5 days to allow elements to enter the wheat seeds;

3) seedling culture: placing the wheat seeds on a seedbed soaked with the organic selenium nutrient solution, and culturing at room temperature in a dark place and in a ventilated place; after the wheat seeds grow to bud embryos and 90% of the bud embryos exceed 1cm, culturing the wheat seeds under the condition of light exposure, keeping the temperature unchanged, and spraying the organic selenium nutrient solution every day;

4) and (4) quality inspection and collection: and (3) the growth time of the wheat seedlings is 10-15 days, 100-200 wheat seedlings are extracted, the selenium content in the wheat seedlings is analyzed to reach 150-250 mg/g, the wheat seedlings are qualified, and the selenium-enriched wheat seedlings are collected.

2. Feeding milk cow with selenium-rich wheat seedling to produce natural selenium-rich milk

Feeding the selenium-rich wheat seedlings under normal feed conditions, and feeding each cow quantitatively without mixing with large batch of feed; the selenium-enriched milk is fed by 100-250 g/day-first cows, and the selenium content in the milk produced by the cows after eating the selenium-enriched milk reaches 24-41.35 ng/ml.

Further, feeding sheep with the selenium-rich wheat seedlings to produce natural selenium-rich goat milk; feeding sheep with 80-120 g/day, wherein the selenium content in the produced sheep milk after eating reaches 18.94-30.17 ng/ml

Further, the organic selenium is selected from selenate polysaccharide, organic chelated water-soluble selenium or selenium-enriched yeast.

further, the organic selenium nutrient solution is 0.2% of selenate polysaccharide solution.

Further, the organic selenium nutrient solution is 0.4% of organic chelated water-soluble selenium solution.

Further, the organic selenium nutrient solution is a selenium-enriched yeast solution with the concentration of 0.25 percent.

Has the advantages that: the invention utilizes organic selenium, has no toxic and side effect, safe product, simple process and easy operation, and the cultivated wheat seedlings have high selenium content and the milk produced by animals has high selenium content after eating.
