Herring Roe

A petroleum-like off-flavour found in seasoned herring roe was implicated as styrene by head-space gas chromatography and gas chromatography-mass spectrometry. The styrene was not detected in the plastic packaging film or in samples of fresh and normal seasoned roe. However, one strain of yeast was isolated from an off-flavoured sample of seasoned herring roe. The styrene was subsequently produced in a test seasoning solution into which the yeast isolate had been inoculated and incubated at 25°C. The yeast isolate was identified as TorulopsisCandida (Saito) Lodder 1922.
