Résumé

The objective was to determine how inhibition of this organism influenced spoilage. The spoilage reactions limiting shelf life were studied. In naturally contaminated modified-atmosphere-packed cod fillets, 500 ppm sodium(2)-calcium-EDTA reduced the growth rate of P. phosphoreum by 40% and shelf life was increased proportionally by 40% at 0 deg C. In aerobically stored cod fillet other microorganisms were responsible for spoilage and sodium(2)-calcium-EDTA had no efect on shelf life. Results confirmed P. phosphoreum as the specific spoilage organism in modified-atmosphere-packed cod. Consequently, any preservation procedure able to reduce growth of P. phosphoreum is likely to extend the shelf life of packed cod.
