ANALYSIS OF AROMA COMPOUNDS IN STRAWBERRY , SOUR CHERRY AND TOMATO BYGAS-CHROMATOGRAPHY AFTER SOLID-PHASE MICRO EXTRACTION

With regard to analysis time and consumption of chemicals the headspac e SPME is the most effective method in relation to conventional method s like liquid extraction and dynamic headspace analysis with solvent d esorption. In some cases the detection of essential aroma compounds in the investigated varieties is incomplete because of the strong discri mination at the adsorption on the fiber. However. in relation to tradi tional clean-up techniques the SPME is a suitable and effective altern ative for screening analyses in plant breeding or quality control with known and consistent matrix.
