Nineteen volatile sulphur compounds, VSC's, including ten thioesters and eight alkyl sulphides, were quantified using SPME-GC-pulsed flame photometric detection, PFPD, in twelve Florida strawberry cultivars. The major headspace VSCs in all 12 cultivars were methanethiol and methyl thioacetate, together comprising 77 to 95% of the total VSCs. Concentrations for the 13 major strawberry VSCs were determined at five maturity stages. Pureed fruit produced 10-20 times higher headspace volatiles than intact berries.
