Polidimethilsiloxane/divinylbenzene (PDMS/DVB), carboxen/polydimethylsiloxane (CAR/ PDMS), polyacrylate (PA) and divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS) fibers were tested and compared for sensitivity beyond conditions that might affect the SPME procedure, such as temperature, concentration of ions and sample volume. The SPME fiber coated with DVB/CAR/PDMS presented the most efficient extraction compounds from the headspace of the product, particularly when the volatiles were extracted at 60ˇć with 2 mL of the sample volume. The addition of salt did not show any significant advantage for the qualification of the volatile fraction. Eighty-three compounds were identified or tentatively identified by GC-MS, being terpenes the most abundant group. %K Headspace Solid-Phase Micro-Extraction (SPME) %K Gas Chromatography-Mass Spectrometry (GC-MS) %K Tiger Nut Beverage %K Volatile Compounds %U http://www.oalib.com/paper/3125393
