Food industry is in continuous development. In particular it is looking for and applying new, tasty and healthy products based mainly on natural ingredients like fruits. These facts are extremely encouraging to make a research in terms of the content of health-oriented compounds in unpopular fruits. For the determination the terpenes and their derivatives in food matrix the most commonly is used one-dimensional Gas Chromatography ; Mass Spectrometer or Flame Ionization Detector (GC-MS, GC-FID). However due to complex composition of food samples and the ability to co-elution for compounds of similar chemical properties is important to use techniques which provides complete separation of the components. For this reason to determine terpenes in fruits comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry combined with proper sample preparation technique was used. Literature data analysis indicates that the determination of terpenes in food is under special investigation for over a decade. The analytical procedures applied for terpene determination in complex matrices as fruits and wines produced from fruits are dominated by sorptive-based and solventless sample preparation techniques.
