Shelled corn was stored for 105 days in jute sacks, open drums, and three kinds of airtight drums (vacuum, low oxygen content, and untreated drums). Grain temperature, moisture content, relative humidity, insects and molds, and quality of grain for food and seed were observed during this period. Grain temperature in airtight drum fluctuated following ambient air temperature and did not show any heat generation due to insect, microflora or grain respiration. In open drum and bag storage, the grain temperature increased with time. Relative humidity in air tight storage was not affected by ambient relative humidity and gradually decreased until equilibrium was reached. Insect population was controlled effectively in all airtight storages compared with open drum storage (9 insects per 100 g of grain) and bag storage (29 insects per 100 g of grain). Molds such as Aspergillus sp. and Penicillium sp. were minimal in grain stored in airtight containers, but the grain in bags and open drums became heavily infested. Germination of grain stored in airtight storage remained high (85.2%) compared with grain in bag (5.6%) and open drum (48.4%) storage. There were no significant changes in color and aroma of grain in airtight containers during the period of evaluation.
