Original Abstract
Three different isolation techniques were tested for the study of mould cheeses aroma compounds: steam distillation, headspace and solid phase microextraction. SPME was chosen and optimised as the most convenient. It offers many advantages: simplicity, rapidity and first of all minimizing thermal, chemical and mechanical modifications of the sample. The volatile components were extracted using CarboxenTM/Polydimethylsiloxane fiber and analysed by gas chromatography. The method showed good reproducibility and sensitivity. Linearity was excellent ( R2 0.9564-0.9952). 46 compounds were identified in Niva cheese using this method: 3 hydrocarbons, 2 aldehydes, 9 ketones, 16 alcohols, 2 esters, 10 fatty acids and 1 sulphur compound. Present contaminants (silicone, phthalates) come probably from laboratory material used.
