Preparation method of high-selenium wheat germ nutrition powder

Abstract

The invention discloses a preparation method of high-selenium wheat germ nutrition powder. The method comprises the following steps: spraying different amounts of organic selenium at different growth periods of wheat, converting external source selenium through leaf surface absorption and storing the converted external source selenium into grains in the forms of selenoprotein, selenium-polysaccharide and seleno-amino acids, finally producing wheat with high selenium content and stable selenium content through continuous bioconcentration, and then processing and preparing the wheat to obtain the high-selenium wheat nutrition powder, wherein the selenium content is stabilized to be more than 5 mg / kg, and the content of selenium in the wheat is guaranteed from the source. The high-selenium wheat germ nutrition powder is prepared through roasting enzyme deactivation, superfine grinding, sieving, compound nutrient adding, vacuum packaging and steam sterilization. The original nutritional ingredients of the prepared wheat are remained, 50-250 micrograms of selenium can be obtained from 10-50 g of high-selenium wheat flour eaten by each person per day, and the requirement of human body on selenium per day can be ensured; moreover, the selenium supplement manner is simple and convenient as all that is needed is to brew the high-selenium wheat germ nutrition powder with warm water.

Description

technical field [0001] The invention relates to the field of wheat planting and processing, in particular to a preparation method of high-selenium wheat germ nutrition powder. Background technique [0002] Selenium is one of the essential trace elements for the human body. Selenium has the reputation of "the king of anti-cancer" and "the spark of life". Selenium and its compounds have the following physiological functions: 1. As a component of glutathione peroxidase, it plays an antioxidant role in humans and animals. 2. Promote growth. 3. Protect the health of cardiovascular and myocardial. 4. Remove the toxic effect of heavy metals in the body. 5. Protect the sound function and vision of the visual organs. 6. It has anti-cancer, anti-cancer and anti-aging effects. The distribution of selenium in nature is extremely uneven. 72% of my country's regions are in selenium-deficient areas. An international conference in 1976 recommended that the selenium requirement be 6...

AI Technical Summary

Problems solved by technology

Second, in the process of production and processing, the high-temperature and high-pressure processing environment leads to the destruction of the form and structure of selenium in selenium-enriched wheat flour, resulting in the loss of organic selenium

Thirdly, the price of selenium-enriched wheat flour is quite high at present, and the consumption capacity of residents is limited, so it is difficult to promote the market and the market share is limited

There is also a production method of selenium-enriched wheat flour, in which selenized carrageenan is added to the wheat flour, and the added amount accounts for 0.05-0.1% of the weight, and the selenium source is directly added, and the safety cannot be guaranteed

For now, the research and industrialization of high-selenium wheat germ nutritional powder have not been reported yet.
