Greenshell (TM) mussels (Perna canaliculus) were dry-stored at 6.44 +/- 0.54 degrees C for 8 days during which time volatile organic compounds (VOCs) were monitored using SPME GC-MS. Thirty-four VOCs were identified in homogenised mussel meat and 29 in the mussel liquor (i.e. the seawater enclosed in the mantle cavity). Of the 34 VOCs identified 20 were reliably identified throughout the storage treatment and 9 were found to change in relative concentration in homogenised mussel meat. Dimethyl sulphide, 1-penten-3-ol, 1-hexen-3-ol and 1-octen-3-ol increased during storage, whereas pentanal, hexanal, heptanal, octanal and 3-undecen-2-one decreased. In the mussel liquor, dimethyl sulphide was undetectable pre-storage, becoming detectable after 2 days. and a large increase was noted after 6 days. SPME GC-MS was a useful tool for monitoring VOC profiles of Greenshell (TM) mussels and could aid in the development of technologies that monitor and improve product quality and consistency.
