Abstract

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.

KEY-WORDS: QPM corn; corn germ; degermed corn yield; corn chemical composition; corn nutrients.
