ABSTRACT

A detailed study was conducted to investigate the influence of modified atmosphere packaging in cashew processing unit on the infestation of Tribolium castaneum Herbst (Coleoptera:Tenebrionidae). Initial vacuum of 600/650mm Hg and final vacuum of 200 mm Hg filled with CO2 and N2 at 400/ 450mm Hg was used to evaluate their impact on the pest infestation at 0, 7, 35 and 45 days. Simultaneously observations like water activity, clumping, moisture content and levels of CO2 and N2 were evaluated. With in the week of experimentation the flexi packages showed high water activity. Clumping of cashew kernels was also observed and clumping was positively resulted with increase in initial vacuum. Reduction of CO2 content was closely related with higher water activity. In this study flushing 250mm of CO2 is suitable for kernels after borma. The results showed that the flushing 250mm of Co2 is not suitable for kernels after slight cooling and also indicate that cashew kernel can effectively be disinfested with high CO2 application in flexible units.
