Embodiment 1

[0022] Production example of 250 micrograms of selenium / bag without adding instant selenium-enriched corn flour

[0023] (1) Cleaning, peeling, and germ removal: select high-quality, high-protein selenium-enriched corn (selenium content 25 micrograms of selenium / gram (dry weight)) for cleaning, peeling, and germ removal;

[0024] (2) Superfine pulverization: the corn after cleaning, peeling and germ removal is coarsely ground, and then superfine pulverization is carried out with superfine pulverization equipment to obtain 150-200 mesh superfine corn flour;

[0025] (3) Ripening: add 1-3% water to the coarse powdered granules, mix them evenly, and then use a twin-screw extruder to form mature corn granules at an extrusion curing temperature of 100-160°C;

[0026] (4) Granulating: pulverize the mature corn granules to obtain 10-20 mesh corn granules;

[0027] (5) Quantitative packaging: Quantitatively pack the obtained in (4) according to the specifications of 10 g / pack to obta...

Abstract

The invention relates to a superfine grinding-puffing-granulating technical method for preparation of no-addition and instant selenium-enrichment corn flour. The method comprises the following steps: selenium biological nutrient reinforced selenium-enrichment corn is taken as raw material and subjected to cleaning, peeling, degerming, coarse grinding, superfine grinding, curing, granulating and quantitative subpackaging, so that no-addition and instant selenium-enrichment corn flour in which granularity is 10-20 meshes, instant time is less than 30 s, and content of selenium is 10-250 mcg / 10 g is prepared. According to the invention, preparation of the instant corn flour under the no-addition condition is realized, the product is fine and smooth in taste, and has the natural flavor of puffed corn flour, quantification of selenium is realized, and an appropriate and scientific choose is provided for different selenium-supplement crowds.

Description

technical field [0001] The invention relates to a method for preparing instant selenium-enriched corn flour by a purely physical process, 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 increasingly serious environmental pollution,...
