Additive-free instant selenium enrichment coarse grain flour as well as preparation method thereof

Abstract

The invention discloses additive-free instant selenium enrichment coarse grain flour as well as a preparation method thereof. The preparation method of the additive-free instant selenium enrichment coarse grain flour is prepared by the following steps: mixing raw materials including selenium enrichment wheat flour (the selenium content is 5-15 microgram/g (dry weight)), selenium enrichment corn flour (the selenium content is 525 microgram/g (dry weight), selenium enrichment rice flour (the selenium content is 0.05-0.3 microgram/g (dry weight)) and selenium enrichment soy meal (the selenium content is 5-30 microgram/g (dry weight)) uniformly, curing, grinding, subpackaging quantitatively and the like, thereby preparing the instant selenium enrichment composite coarse grain flour which has the grain size of 20-30 meshes, has the instant time less than 20 seconds and can reach the maximal selenium content of 855microgram/10g. According to the invention, the instant selenium enrichment coarse grain flour is prepared under the condition of no additive; the additive-free instant selenium enrichment coarse grain flour is fine and smooth in mouthfeel, has the flavor of puffing coarse grains, moreover, realizes selenium quantification, and can meet selenium supplement requirement of different people which are lack of selenium.

Description

technical field [0001] The invention relates to an instant selenium-enriched miscellaneous grain powder for quantitative selenium supplementation and a preparation method thereof, belonging to the field of instant food preparation. Background technique [0002] Selenium is an essential trace mineral element for humans and mammals. It is an essential component of as many as 30 active enzymes such as glutathione peroxidase (GSH-Px) and selenoprotein P. It has anti-oxidation, heart protection , anti-hepatic necrosis, prevention and treatment of myopia and cataracts, detoxification, improve immunity, delay aging and enhance reproductive function and other physiological functions. According to incomplete statistics, there are more than 40 countries and regions lacking selenium in the world, and 72% of my country's regions are selenium-severely deficient areas, and nearly 900 million people are suffering from health threats caused by selenium deficiency. In addition, with the inc...
