Pulses are an important commodity group of crops that provide high quality protein complementing cereal proteins for pre-dominantly substantial vegetarian population of india . as per the fao study for the year 2014, globally, the indian position in chickpea production is first with 9.88 million tonnes in the harvested area of 10.74 mha followed by pakistan (0.82 mt in 0.99 mha) and australia (0.75mt in 0.58 mha). chickpea is one of the most important crop of india contributing about 30 % of total pulse acreage and about 40 % of total pulse production. as compared to the other pulses, chickpea contributes the single largest share in india’s export basket registering 84.87% (216.93 tt) and 62.16% (61.21 tt) share in the total pulses export during 2015-16 and 2016-17, respectively (doc).chickpea is an affordable source of protein, carbohydrates, minerals, vitamins, dietary fiber, folate, -carotene and health-promoting fatty acids. additionally, it helps in lowering the risk of various chronic diseases . ozone (o3) as a potential fumigant to control stored-grain insects has attracted attention recently owing to its advantages of easy generation at the treatment site and no chemical residues . ozone, or triatomic oxygen (o3), is a powerful disinfectant and oxidizing agent. it has been considered as a gras (generally recognized as safe) substance and used in a number of applications in the food industry for destruction or detoxification of chemicals or microorganisms . ozone have been reported to not only successfully deactivate micro flora and its related mycotoxins but also effectively kill coleopterous and lepidopterous stored-product insect pests (isiber and athanassiou, 2015). ozone was observed to kill adults of phosphine susceptible and resistant strains of t. castanesum, o. surinamensis, s. oryzae, and s. zeamais (xe et al., 2016). o3 was successfully evaluated for decontaminating nuts and grains from aspergillus and penicillium species. it was also found to be effective in reducing the mycotoxin levels in the infected grains . the length of the different phase are affected by the amount of grain, ozone flow rate, initial concentration of ozone and as well as temperature and grain moisture content. sometimes the higher doses of ozone and longer treatment duration were needed to achieve a good result.previous researches revealed that aflatoxin b1, ota, zen and don in aqueous solution could be rapidly and completely degraded within a few tens of seconds using ozone gas . the key to successful ozone fumigation involves maintaining a critical concentration for a stipulated period of time during the fumigation treatment. a detail study is needed to find out the efficiency of o3 in eliminating major storage, pests and in controlling microbial growth in chickpea and its effect on the quality characteristics, limited research findings are available pertaining to the efficiency of ozone in treating infested and infected pulse crops like chickpea.
