Resumo
The hardness of corn endosperm is an essential attribute
for farmers and industries that use this cereal as a raw material.
However, Quality Protein Maize (QPM) presents alterations in
the grain texture, which hinder its commercial use. This study
evaluated the industrial yield in the kernel degerming and
endosperm fractionation, and chemical composition of a QPM
variety, regarding commercial common corn hybrids. QPM and
common corn genotypes were processed using the dry degerming
method, and the resulting yield was expressed as the ratio of the
weight of fractions obtained to the initial weight of the whole
corn. Compared to commercial corn hybrids, QPM presented
lower endosperm yield, higher germ and fine fraction (< 0.425
mm) yield and the same hominy yield in endosperm fractionation.
QPM showed similar protein, lipid, and ash levels and higher
levels of dietary fiber and iron in the germ, when compared to
common corn hybrids. QPM and its fractions have potential as
a nutritious raw material for use by the food industry.
