A portable modified atmospheric packaging (MAP) unit was developed for grain disinfestation. The developed MAP unit consisted of a grain holding unit and cover, sealing unit, flushing nozzle, pressure regulator, solenoid valve with timer, working table and carbon dioxide cylinder. The operational parameters of the developed MAP unit viz., flushing pressure and flushing duration was optimized for Bengal gram. The flushing pressure of 5 kg/cm2 for 10 s was found to retain maximum concentration of CO2 (94.8%) and minimum of O2 (0.1%) in Bengal gram packages of one kg capacity with highest desirability of 97.8%. The results on storage of Bengal gram showed no incidence of infestation and highest germination (%) in PET packages compared to PE and PP at the end of nine months. Similarly, CO2 retention was observed to be for longer period in PET compared to PE and PP. The estimated cost of the developed MAP unit was found to be Rs. 8350.00 and the cost of packaging was worked out to be Rs. 2.90 for PET followed by PE and PP each of Rs.1.90.
