Comparative assessment of the qualitative loss of maize grain (12.2%, w.b.) in different storage bags was made. The storage behavior of freshly harvested and chemically treated (Alminium Phospide) maize grain was studied at ambient condition (30± 5 oC) in four different modes, i.e. in hermetic bags (super bags), polyethylene bags, plastic bags and jute bags. Weekly changes in physical properties such as grain moisture content, water activity and colour index and degradability in terms of degree of insect infestation, germination percentage and production of aflatoxin were recorded for 8 months. It was observed that the variation in grain moisture content (0.245, w.b), water activity (0.132) and colour index (0.232) was least in the super grain bag while the variations were maximum in case of jute bags (0.855, 0.166 and 0.426 respectively). The germination percentage was maximum for maize stored in super bags (82%) and least for jute bags (07%) after 8 months storage period. No visible damage due to pest infestation was observed maize samples stored in super bags. The level of aflatoxin in stored maize in hermetic bags was least and under the acceptable limit i.e. 20ppb throughout the storage period. However the aflatoxin levels in other storage bags were around 100-150 ppb rendering it unfit for human consumption.
