Influence of ozone gas on cowpea beetle (Callosobruchus maculatus) as well as seed technological characteristics

Abstract: The present study aimed to investigate the effects of ozone gas exposure (at 2, 4 and 6 hours) treatments on controlling the life stages of Callosobruchus maculatus insects (eggs, larvae and adults) for infesting cowpea seeds and their effects on some insect enzymes (phenoloxidase, peroxidase, ?-esterases and ?-esterases). The ozonated cowpea seed samples (ozone exposure for 6 h) were assessed with respect to some physicochemical and technological characteristics. The insect eggs were highly tolerant to ozone followed by adults and larvae stages which were the lowest tolerant. The maximum reduction percentage in F1 progeny was found in eggs followed by larvae stages at 6 h of the exposure period. The ozone decreased the activity of peroxidase, ?-esterases and ?-esterases in adult insects except for phenoloxidase which was higher in treated insects compared with control sample. The ozonated cowpea seeds were lower in germination percentages, the 1000-seed weights and starch granules size compared with control. Ozone treatment increased lightness, redness and yellowness values of seeds. Results showed, also, an increase in fiber and ash contents and in vitro protein digestibility; while the moisture, protein, fat and minerals (calcium, iron, zinc and phosphorus) were lower in ozonated samples compared with the control. Ozone treatment reduced the cooking time and total soluble solids. Ozonated cowpea seed samples were accepted in all tested sensorial attributes compared with control samples before and after storage periods (12 weeks).
