Abstract:		"Consumption and production of superfruits has been increasing. Highly colored fruits often have bitter and astringent components that may make them undesirable, especially when processed. Many pomegranate volatile reports involved commercial samples, complicated isolation methods, or blending and concentrating that were from arils only, cultivars other than 'Wonderful', or mixed cultivars. Solid phase microextraction (SPME), polydimethylsiloxane stir bar sorptive extraction, and Tenax adsorption were performed with freshly pressed 'Wonderful' juices, commercial juices and concentrates. Using SPME, 36 compounds were isolated in whole pressed 'Wonderful' juices, including 18 of the 21 consensus compounds. In arils-only juices, 41 compounds were isolated by SPME, including 17 of the consensus volatiles. Dramatic variation existed in volatiles recovered in commercial juices and isolation of consensus compounds was sporadic. This article and summary of the literature serves to possibly deliver an improved volatile data set via a rapid method for fresh and partially processed (pressed) pomegranates"
