Application of Ozone to Control Dried Fig Pests—Oryzaephilus surinamensis -Coleoptera: Silvanidae- and Ephestia kuehniella -Lepidoptera: Pyralidae-—and Its Organoleptic Properties
Year
: 2017
Abstract: Ozone is a powerful oxidant which can be used for killing insects and microorganisms. In this study, ozone was
applied in the gaseous form to control two species of pests in stored dried figs. The samples of figs -50 g each-
were infested with adults of Oryzaephilus surinamensis L. and larvae of Ephestia kuehniella Zeller and were
subjected to different combinations of ozone concentrations -2, 3, and 5 ppm- and exposure times -15, 30, 45,
60, and 90 min-. Changes in organoleptic properties -color, sweetness, firmness, aroma, and overall acceptability-
during ozonation were studied. The results showed that the mortality rate increased with an increase in
ozone concentration and exposure time. The total mortality of both pests was achieved at an ozone concentration
of 5ppm and exposure time of 90 min. Sensory evaluation showed that ozone only had a negligible effect
on aroma. Therefore, the usage of ozone is recommended during the postharvest process instead of other
chemical fumigants, such as methyl bromide and phosphine.
