Optimization of process parameters to manage Callosobruchus maculatus (Fabricius) and maintain quality parameters of green gram grains (Vigna radiata)

The present study conducted to optimize the effect of different process parameters i.e. deltamethrin (0.025-0.075%), canola oil (0.50-1.50%), kinnow peel powder (0.50-1.50%) and storage period (2-6 month) to maintain physical and quality attributes by managing Callosobruchus maculatus in stored green gram grains ( Vigna radiata ). Under optimized conditions, the process parameters i.e. deltamethrin @ 0.027% for treating jute bags, canola oil @ 1.43% and kinnow peel powder @ 0.85% for treating green gram grains and stored for 6 month showed very less grain damage (0.17%) with minimum colour change (3.96) and optimum protein content (21.92%). The grains treated with optimized parameters required 62 min for their proper cooking and for overall acceptability, these grains scored 8 points (liked very much) based on hedonic sale. Above treated green gram samples with optimized parameters when compared with other tested treatments found to be in consonance with hermetic zerofly bag and metallic drum stored green gram grains with sand layer of 7 cm, revealing all the practices were at par for the effective control of pulse beetle without affecting the physical and quality attributes of green gram grains.
