The significance of the work is that this is one of the first studies that demonstrates the effect of various corn grain storage conditions (refrigerated and ambient) on ethanol yields. Physiological changes in corn during storage influences dry grind process and impacts ethanol yields. This study evaluated one such factor, i.e., changes in the various protein fractions in corn grain such as albumin, globulin, prolamin and glutelin during storage and their impact on ethanol yields. The main findings were that ethanol yields were significantly impacted by storage time but not by storage temperatures (-7 to 23°C) used in this study and ethanol yields at 24 h of fermentation are affected by changes in glutelin and prolamin levels during storage. Variation in ethanol yields can cause significant losses in dry grind ethanol plants, and information from this study can be used to implement process changes to avoid such losses.
