Wet-Milling Qualities of Dent Corn (Zea mays indentata L.) Hybrids Grown as Main Crop in Adana and Sakarya
Although dent corn (Zea mays indentata L.) production has steadily increased in Turkey, limited research has been conducted on suitability of corn hybrids for starch production, i.e., wet-milling quality. This research was therefore conducted to determine physical properties (thousand-kernel weight, hectoliter weight, hardness and density), chemical compositions (protein, fat, ash and starch contents) and wet-milling quality parameters (steep-water solids, germ, gluten, total fiber, starch yields, etc.) of dent corn hybrids grown as the main crop in Adana and Sakarya. Corn hybrids grown in Adana revealed significant differences in their physical, chemical and wet-milling properties. The hybrids Helen, P 31 P 41, P 31 G 98, P 31 N 27 and P 32 W 86 were found to have superior wet-milling quality. The hybrids grown in Sakarya also exhibited significant differences in certain physical and chemical parameters, yet they did not differ significantly in starch yield, recovery and purity, inferring their similar wet-milling qualities. Additionally, positive correlations of hectoliter weight with hardness, density and protein content, negative correlations of protein content with starch content, yield and recovery, positive correlation of starch content with starch yield were of noteworthy.
