Notes:
Quantitative data were obtained for total carbonyls, total monocarbonyls, methyl ketones, saturated aldehydes, 2-enals and 2,4dienals from fresh, reduced surface flora (Dip) and inoculated muscle samples incubated at the optimal growth temperature of the respective bacteria. Individual monocarbonyl compounds were identified by thin-layer and gas liquid chromatography. Micrococcus cryophilus, Pseudomonas fluorescens and Staphylococcus aureus decreased total carbonyls by 57, 18 and 43%, respectively, and total monocarbonyls by 53, 20 and 33%, respectively. Pediococcus cerevisiae increased the total carbonyl and total monocarbonyl content by 70 and 71%. Concentrations of carbonyls in the control samples were directly related to temperature of incubation. Methyl ketones, saturated aldehydes, 2-enals and 2,4dienals were decreased by M. cryophilus, Ps. fluorescens and S. aureus but each monocarbonyl class was increased by P. cerevisiae.
