Selenium fortified nutritional wheat meal containing L-selenium-methyl selenocysteine

Abstract

The invention discloses selenium fortified nutritional wheat meal containing L-selenium-methyl selenocysteine. L-selenium-methyl selenocysteine intensifying agents are prepared into L-selenium-methyl selenocysteine intensifying agent premix feeds, and each ton of wheat meal main ingredients are mixed with 1kg of L-selenium-methyl selenocysteine intensifying agent premix feeds. The L-selenium-methyl selenocysteine intensifying agent premix feeds comprise 0.5g of L-selenium-methyl selenocysteine, 99.5g of light tricalcium phosphate flow carriers, 200g of wheat starch diluents and 700g of modified starch diluents, and the sum of all components is 1000g. The purity of the L-selenium-methyl selenocysteine is 96%, the L-selenium-methyl selenocysteine contains 43% of selenium, and the content of the selenium in a finished product is 140-280 micrograms / kg. The selenium fortified nutritional wheat meal is simple in process, convenient to process and operate, stable in product quality, easy to popularize and suitable for industrial production, micronutrients are uniformly added, continuous proportioning production can be realized, and selenium micronutrients required by a human body can be effectively supplemented.

Description

technical field [0001] The invention relates to the technical field of flour processing, in particular to a selenium-enhanced nutritional wheat flour containing L-selenium-methylselenocysteine. Background technique [0002] With the continuous improvement of living standards, the public has increasingly strong requirements for nutrition and health, and the lack and imbalance of dietary nutrients are global problems. Therefore, more and more attention has been paid to nutritional fortification. The nutritional fortification of staple foods is to improve nutrition. effective way to level. [0003] Selenium (Se) is honored as "the fire of life" by the medical and nutritional circles at home and abroad, and enjoys the reputation of "longevity element", "king of anti-cancer" and "natural antidote", and plays a huge role in human health. It is irreplaceable by other substances. Selenium deficiency will directly lead to the decline of human immunity; as an antioxidant, selenium ca...

Problems solved by technology

[0004] Chinese residents' dietary nutrient reference intake (DRIs) recommended selenium intake (RNI) 20 micrograms for 1-4 years old, 25 micrograms for 4-7 years old, 35 micrograms for 7-11 years old, 45 micrograms for 11-14 years old, 14 and above 50 micrograms, 65 micrograms for nursing mothers; the highest intake is 120 micrograms for 1-4 years old, 180 micrograms for 4-7 years old, 240 micrograms for 7-11 years old, 300 micrograms for 11-14 years old, 360 micrograms for 14-18 years old, 400 micrograms for 18 years old and above Micrograms; According to the results of relevant nutrition surveys in my country, the daily selenium intake of adults is only 26.63 micrograms, and selenium deficiency is currently widespread; grain foods such as flour are the main source of human nutrition, and these natural foods have low selenium content, so It is difficult for people to take in enough selenium from food; therefore, adding selenium to wheat flour to produce selenium-fortified nutritional flour is of great significance for improving the low-selenium dietary structure common to Chinese residents, preventing diseases, and improving human immunity and health. Important social significance; as far as we know, there is no report on the method of using L-selenium-methylselenocysteine ​​organic selenium as a raw material to add it to wheat flour to produce selenium-enhanced nutritional flour
