VACUUM-PACKAGING OF FRESH FISH: EFFECT OF OXYGEN PERMEABILITY OF PACKAGING MATERIAL ON THE DEVELOPMENT OF BOTULINAL TOXIN.

Author(s) : GOLA S., ROSSI M.

Summary

HAKE FILLETS, INOCULATED AT 100/G AND 100,000/G LEVELS WITH SPORES AND VEGETATIVE CELLS OF 5 C. BOTULINUM STRAINS (A, B, E TYPES) WERE VACUUM-PACKAGED IN MATERIALS WITH HIGH AND LOW OXYGEN PERMEABILITY, STORED AT 283 K (10 DEG C) OR SUBMITTED TO TEMPERATURE ABUSE OF 291 K (18 DEG C). ORGANOLEPTIC SPOILAGE TOOK PLACE BEFORE THE ONSET OF TOXIN DEVELOPMENT, SINCE THE FORMER OCCURRED AFTER 3-5 DAYS AT 283 K AND AFTER 24 HOURS AT 291 K, AND THE LATTER AFTER 14 DAYS AT 283 K AND AFTER 4 DAYS AT 291 K. OXYGEN PERMEABILITY OF PACKAGING MATERIALS HAD A MARGINAL EFFECT ON TOXIN DEVELOPMENT, WHICH DEPENDED MAINLY ON STORAGE CONDITIONS AND INOCULUM LEVEL.
