Delineating the effect of gaseous ozone on disinfestation efficacy, protein quality, dehulling efficiency, cooking time and surface morphology of chickpea grains during storage

Abstract Ozone is one of the acceptable and economically viable techniques for treating grains during storage for its residue-free and environment-friendly nature. A laboratory-scale and pilot-scale ozone disinfestation system for chickpea grains was developed. Chickpeas conditioned to different moisture levels (10, 12, 14% wb), infested with Callosobruchus maculatus were stored at different temperatures (15, 23, 31 °C), with varying bed thickness (50, 75, 100 mm), and samples were disinfested by ozone gas at different concentrations (500, 750, 1000 ppm). Ozone concentration, moisture content of the grain, grain bed thickness, and storage temperature had significant (p
