Volatile compounds associated with the aerobic growth of some Pseudomonas species on beef

Abstract
Five strains representing 4 clusters of meat spoilage pseudomonads were grown on sterile beef at 5.degree. C. After 7 days incubation, sensory assessments were made and the chemical composition of the headspace gases determined by gas chromatography-mass spectometry. There was good correlation between odor descriptions and chemical data for 3 of the strains. The most numerous types of product were esters and S-containing compounds. Of 45 compounds identified, only 1-undecene was common to all the tested strains.
