|Abstract:||Three areas of wet milling characteristics of yellow dent corn were investigated in this study. The first one determined the effects of variety, harvest moisture and drying air temperature on twelve quality factors related to the millability of corn. A split-split plot experimental design was used to evaluate the effects. Variety was found to significantly influence the measurement of each individual quality factors among the varieties. Increased maturity of the corn, estimated by decreasing harvest moisture, resulted in increased test weight, increased germination and decreased equilibrium moisture contents.
Second was the determination of the effects of variety, harvest moisture and drying air temperature on the starch recovery of corn. A split-split plot experimental design was used to evaluate these effects. Measurements from the first area were used to develop a prediction equation for starch recovery. Starch recovery was not significantly different among the varieties, however increasing harvest moisture and drying air temperatures, decreased starch recovery.
The third area determined the effects of harvest moisture and drying air temperature on the potential oil yield from the germs of one variety of corn recovered during wet milling. Potential oil yield of hand picked, hand shelled yellow dent corn decreased as harvest moisture and drying air temperature increased.
