Dry-Milling Properties of Maize.

Chemical composition and physical properties of 18 African maize samples were determined and correlated with their dry-milling performance. Semolina yield could be predicted (at almost 60%) from ash content (main factor, correlation coefficient -0.64) and sphericity or dent kernel percentage (cofactors). Vitreousness was not significantly correlated (at the 0.05 level) with semolina yield. Vitreousness, which was very time-consuming to measure, could be evaluated at almost 90% from density and dent kernel percentage or ash content. Lipid content of recovered semolinas was also positively correlated with kernel ash content. Thus, maize varieties with low ash content gave high yields of semolina with low lipid content.
