MICROBIAL FLORA OF COD FILLETS (GADUS MORHUA) STORED AT 275 K (2 DEG C) IN DIFFERENT MIXTURES OF CARBON DIOXIDE AND NITROGEN/OXYGEN.

Type of article: Article

Summary

THE SHELF LIFE, EXPRESSED AS THE TIME FOR THE MICROFLORA TO REACH 1,000,000 CFU/G, SUCCESSIVELY INCREASED AS THE CO2 CONCENTRATION INCREASED. IN 100% CO2, THE TOTAL AEROBIC COUNT DID NOT EXCEED 1,000,000 CFU/G. THE MICROFLORA OF THE FRESH FILLETS CONSISTED OF FLAVOBACTERIUM SPP, ALTEROMONAS PUTREFACIENS, MORAXELLA-LIKE ORGANISMS AND PSEUDOMONAS SPP. AFTER 6 DAYS IN AIR, THE TOTAL AEROBIC COUNT HAD REACHED 50 MILLIONS CFU/G AND THE MICROFLORA WAS DOMINATED BY A. PUTREFACIENS (62%) AND NON-FLUORESCENT PSEUDOMONAS SPP (28%). AFTER 26 TO 34 DAYS OF STORAGE, LACTOBACILLUS SPP AND A. PUTREFACIENS DOMINATED IN THE DIFFERENT GAS MIXTURES. IT IS SUGGESTED THAT A SUITABLE GAS MIXTURE FOR RETAIL PACKAGES SHOULD BE 50% CO2/50% O2.
