Abstract
In this study, whole and ground pomegranate (cv. Hicaz) seeds using conventional and microwave ovens were investigated under different parameter. The results show that the total phenolic contents of whole and ground seeds roasted in oven at (150 °C) and microwave at (720 W) for 10 and 20 min, and 5 and 7.5 min, respectively, were found to be slightly higher than those of the control group. In addition, the same roasting method of microwave at (720 W), ground seed oils showed greater fatty acids contents than those of whole seed oils. According to achieved results, roasting techniques used caused noticeable fluctuations of phenolic and fatty acids contents and that depending on which counterparts of pomegranate seeds treated. In addition, a caution recommended when using microwave oven in roasting pomegranate seeds to prevent undesirable alteration or losing of bioactive properties of this value-added product.
