Volatile Ketones and Alcohols of Codworms (Terranova decipiens) from Axenic Culture and Fresh Fish Muscle

Simple techniques for the gas–liquid chromatographic analysis of volatile ketones and alcohols from cultures or native codworms, Terranova decipiens, or from the axenic culture medium, are described. Three ketones (propanone-2, butanone-2, pentanone-3) and two alcohols (butanol-2, pentanol-3) were observed. The proportion of alcohols to ketones was different in culture medium and in native worms from cod, but the latter were qualitatively and quantitatively similar in fresh cod taken in March and September.
