The invention relates to a
selenium-enriched instant corn coarse cereal
powder solid beverage. The
selenium-enriched instant corn coarse cereal
powder solid beverage is made from the following components in parts by weight: 8-10 parts of
selenium-enriched
corn flour, 3-4 parts of oat flour, 1-1.5 parts of
millet flour and 1-1.5 parts of
coix seed
powder. The invention further discloses a preparation method of the selenium-enriched instant corn coarse cereal powder
solid beverage. The preparation method comprises the following steps that selenium-enriched corn after biological
nutrient enrichment is used as a
raw material of selenium-enriched enzymolysis
corn flour, the selenium-enriched enzymolysis
corn flour is prepared through the technologies of performing cleaning, performing peeling, performing degerming, performing coarse crushing, performing extruding and puffing, performing fine crushing, performing enzymolysis, performing
filtration, performing concentration, performing
vacuum drying and the like, the particle size of the selenium-enriched enzymolysis corn flour is controlled to be 60-100-mesh, then the selenium-enriched enzymolysis corn flour is mixed with oat flour,
millet flour and
coix seed powder, and the selenium-enriched instant corn coarse cereal powder solid beverage is made. According to the selenium-enriched instant corn coarse cereal powder solid beverage disclosed by the invention, the problem that the corn flour is easy to
agglomerate and stick to cups is solved, the selenium-enriched instant corn coarse cereal powder solid beverage has original fragrance of cereals and is rich in
nutrition and easy to digest and absorb, quantitation of selenium can be realized, and scientific selection is provided for different
crowds needing selenium supplement.
