Extraction of headspace (HS) volatiles compounds was performed using solid phase microextraction (SPME) with an 85 mm Carboxen/Polydimethylsiloxane (CAR/PDMS) fibre as described Five grams of minced sausage were weighted into a 20 ml HS vial sealed with a PTFE faced silicone septum and 0.75 mg of BHT was added. Before extraction, the vial was equilibrated at 37 C for 30 min and then, SPME fibre was exposed to the headspace during 3 h at 37 C.
