The effect of vacuum and modified atmospheric storage on quality parameters of insect infested bengal gram was studied. The bengal gram samples were packed with five insects of Callosobruchus chinensis under vacuum, modified atmosphere and ambient storage conditions for 120 days, in laminated LDPE bags. To find the effect of vacuum and nitrogen gas as modified storage on the parameters viz., moisture content, germination percentage, change in weight, rehydration capacity and protein content of bengal gram were analysed on every 30 days interval for 120 days. At each interval of storage, the significant differences were observed in increase in moisture content, rehydration capacity and change in weight and decrease in protein content and germination percentage in respective storage conditions. The observation found that increase in moisture content on wet basis ranged from 8.2% to 8.46%, 8.86% and 9.86%, rehydration capacity has increased from 0.210 to 0.235, 0.243 and 0.250g/g, change in weight from 0.0g/g to 0.333, 1.767 and 2.5 g/g and protein content has decreased from 19.650% to 18.063, 16.338 and 16.063% and germination percentage has decreased from 100% to 99.333%, 95%, 84.667% in vacuum, modified storage and ambient condition respectively. The results showed that vacuum is the best storage technique for bengal gram storage.
