Method for cultivating high-selenium corn and method for preparing nutrition powder of high-selenium corn

Abstract

The invention discloses a method for cultivating high-selenium corn and a method for preparing nutrition powder of the high-selenium corn. According to the method for cultivating the high-selenium corn, firstly the variety of the corn is selected, the land is selected and prepared, the corn is planted, and organic selenium is sprayed in the heading period, the formation period of grains and the milk-ripe period at a time respectively. The method for preparing the nutrition powder of the high-selenium corn comprises the steps that husks and germs of the high-selenium corn are removed, then the corn is milled and smashed at a low speed of 1400r/min to obtain corn powder, amylase enzymolysis, protease enzymolysis and vacuum spraying drying are conducted in sequence, and then the high-selenium corn powder is mixed with a composite nutrient to obtain the nutrition powder of the high-selenium corn. By means of the method for cultivating the high-selenium corn and the method for preparing the nutrition powder of the high-selenium corn, the selenium content of the high-selenium corn can reach more than 4mg/kg and is stable. The rich-selenium cultivation method is easy to operate, is low in cost, has certain generalization performance and can process and prepare the nutrition powder of the high-selenium corn. The nutrition powder of the high-selenium corn has high organic selenium content and balanced nutrition, and plays a role in regulating the nutrition of the youth and the old.

Description

technical field [0001] The invention relates to a cultivation method for high-selenium corn, and provides a method for preparing high-selenium corn nutrition powder by using the high-selenium corn planted by the cultivation method as a raw material. 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 effects: 1. Anti-cancer, anti-cancer, tumor inhibition 2. Anti-oxidation, anti-aging 3. Protection, repair, and activation of cells 4. Improve human immunity 5. Detoxification and detoxification, anti-radiation 6. Protect the heart and brain blood vessels and liver. Residents in selenium-deficient areas have higher incidence rates of cancer, cardiovascular disease, Keshan disease, and Kaschin-Beck disease than in selenium-rich areas. The distribution of selenium in nature is extremely uneven. 72% of my cou...

Problems solved by technology

The selenium-enriched corn flour that appears on the market can all meet the selenium-enriched standard, but the research and industrialization of high-selenium corn nutrition powder have not been reported yet. The corn produced by the high-selenium corn cultivation technology has been tested by a testing center with testing qualifications. The selenium content of high-selenium corn nutrition powder is ≥4.0mg / kg. Compared with ordinary selenium-enriched corn flour, the selenium content is increased by 10-40 times. High-selenium corn nutrition powder has the characteristics of stable selenium content, less consumption, and good selenium supplementation effect.
