In this work the suitability of extracting volatiles with polar, non-polar and mixed-polar SPME fibers is presented. Peach aroma constituents were devided in groups consisted of components representing immature (alchohols and aldehydes) and mature (lactones and terpen) peach aroma. The content of volatiles were calculated and expressed in equivalents of internal standard and standard addition method. For the internal standard, 1-octanol was chosen. The fibers which propose the maximal performance were PDMS, PDMS/CAR and PDMS/CAR/DVB.
