A kind of method for preparing instant high-selenium corn flour by dry pressing

Abstract

The invention discloses a method for preparing instant corn flakes which are free of additives, instant and rich in selenium through dry method tableting. The preparation method is characterized by comprising the following steps: taking biological selenium nutrient enriched selenium-rich corns as a raw material, conducting processes of cleaning, removing the peel, degerming, grinding into coarse powder, curing, grinding into fine powder, dry method tableting, and quantitative subpackaging to obtain the instant selenium-rich corn flakes free of additives, wherein each of the corn flakes is 1 cm long, 1 cm wide and 0.1 cm thick; the instant time is shorter than 10 seconds; the selenium content is 10-250 micrograms per 10 grams. The preparation method disclosed by the invention not only realizes preparation of the instant corn flour without additives, which is fine and smooth in taste and flavored in puffing corn flour, but also realizes selenium quantitation to provide appropriate and scientific selection for different populations with selenium supplementing requirements.

Description

technical field [0001] The invention relates to a method for preparing instant selenium-enriched cornflakes without adding, and belongs 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, pneumonia, ...

AI Technical Summary

Problems solved by technology

[0004] (1) Corn flour agglomeration: Corn is processed into selenium-enriched corn flour products through processes such as peeling, degerming, crushing, and puffing. Dispersed, unable to achieve instant effect;

[0005] (2) Sticky wall: Due to a large amount of agglomeration during brewing, the lumpy corn flour is easy to stick to the wall of the cup, making it difficult to be removed during rinsing

[0006] And the method for solving this problem at present is all by adding methods such as dispersant, as: in " the development of high-fiber puffed corn meal " (Li Jixin, Liu Ya, Zheng Gang, Ye Zhijun, food and feed industry, 1999) by adding rice bran, High-fiber ingredients such as soybean bran realize the palatability and solubility of corn flour; in "The Development of Instant Black Waxy Corn Flour" (Zhang Zhong, Pan Wenli, Grain, Oil and Food Science and Technology, 2005), just add defatted soybean flour, oligomeric Fructose and milk powder are used to realize the instant solubility of corn flour; in "Instant Wild Plant Synthetic Corn Compressed Food Granules and Its Processing Method" (ZL200610010134.7), the corn is soaked in the leaching solution of wild mushrooms, jujubes, pine nuts, Codonopsis pilosula, etc. , and then milling and compressing to obtain instant synthetic corn flour granules, although the nutritional labeling of corn flour is increased, a variety of raw materials are introduced simultaneously, which destroys the naturalness of the product; instant corn granules and production methods thereof (application number: 201110050672. In X), although it is claimed that instant dissolution can be achieved, the 20-40 mesh particles have obvious rough taste, and there will also be problems of agglomeration, difficulty in dispersing, and sticking to the wall

However, none of these solutions can realize the concept of pure natural, healthy food without additives, let alone the principle of scientific and quantitative selenium supplementation
