Characterisation of volatile compounds in selected citrus fruits from Asia

Abstract

In this study the volatile compounds present in Pontianak orange (Citrus nobilis var microcarpa) from Indonesia, Mosambi (Citrus sinensis var mosambi) from India and Dalandan (Citrus reticulata) from Philippines were characterised. The flavour compounds of the hand-squeezed juices were extracted by headspace solid-phase microextraction (SPME) and solvent extraction methods. More than 70 compounds could be identified and most of them are commonly found in citrus fruits. However, some less common volatile compounds were identified the citrus samples, such as 4-ethenyl cyclohexene, dibutyl sulfide, β-chamigrene, eremophilene and isopiperitenone. © 2006 Elsevier B.V.
