Abstract The odour of silurus (Silurus glanis)coming from two types of rearing environment developed in France was studied.Odour sensory analysis was performed on cooked fillets of silurus.The odour representativeness of extracts obtained by dynamic headspace was assessed.Two methods of extract collection were compared.Rearing environment had an effect on the odour of cooked filles of silurus.Silurus reared in outdoor ponds for 2years with no renewal of water had a stronger odour of hay,cut grass and hot milk and a weaker odour of moudly,hard-boiled egg and cooked cabbage than silurus reared in indoor concrete ponds for 1 year with renewed geothermal water.Odour extracts collected with the Teflon bag method were more representative of the odour of cooked fillets of silurus than those collected with odour of cooked fillets of silurus.
