Due to their pleasant aroma citrus peel oils are currently used in a variety of cosmetics, foods or food preparations, and also in pharmaceutical preparations. However, only a few systematic studies on the chemical compounds responsible for the aroma of such essential oils exist. Using the concept of “molecular sensory science” the key odorants in peel oils of Indonesian Pontianak orange and Brazilian green mandarin were identified. Furthermore, their natural concentrations were quantified by mass spectrometry on the basis of stable isotope dilution assays. 14 compounds of the analysed mandarin peel oils were structurally identical. The significant differences in the aroma profiles of the peel oils were caused by different concentrations of some key compounds, and in particular, by the presence of the highly odour-active 1-phenylethanethiol in the Pontianak orange peel.
