Abstract: Present experiment was conducted to study the effect of microwave pretreatment on recovery and quality of pomegranate seed oil. Samples were pretreated in microwave oven at microwave power levels (MWP) of 360, 540, 720 and 900 W for pretreatment time (PT) of 30, 60, 90, and 120 seconds and extracted for 3, 4 and 5 h extraction time (ET). The extraction yield was increased with increase in microwave power applied, pretreatment time as well as extraction time. Light microscopy was carried out to study the effect of microwave radiation on the microstructural changes in cell structure pomegranate seeds. It was observed that, the extraction yield from the microwave treated samples was higher as compared to control samples. The microwave pretreatment was also found to be effective in reducing the extraction time. Light microscopy showed the rupture of cells and loosening of oil bodies. The optimum conditions for microwave pretreatment were 720 watt, pretreatment time of 60 s and extraction time of 4 h.
