Summary

A FLOW-THROUGH CONTROLLED ATMOSPHERE PACKAGING SYSTEM USING A NUMBER OF DIFFERENT CARBON DIOXIDE-ENRICHED GASEOUS COMPOSITIONS WAS DEMONSTRATED TO BE EFFECTIVE IN RETARDING THE GROWTH OF MICROORGANISMS ON FRESH SWORDFISH STEAKS HELD AT 275 K (2 DEG C) FOR 22 D. DURING THE FIRST 14 D OF STORAGE, PSEUDOMONAS SPP REPRESENTED A MAJOR PART OF THE MICROFLORA IN ALL GASEOUS ATMOSPHERES TESTED. IN ATMOSPHERES CONTAINING 70% CO2 OR IN PURE CO2, HETEROFERMENTATIVE LACTOBACILLUS SPP AND BROCHOTHRIX THERMOSPHACTA WERE A MAJOR PART OF THE MICROFLORA AFTER THE 14TH DAY OF STORAGE. BOTH TOTAL VOLATILE NITROGEN AND TRIMETHYLAMINE INCREASED MORE SLOWLY IN CO2-ENRICHED ATMOSPHERES. ADVANTAGES OF USING A CONTROLLED ATMOSPHERE: (A) A STABLE GAS COMPOSITION, (B) INDIVIDUAL PORTIONS CAN BE REMOVED FROM A MASTER PACKAGE WITHOUT LOOSING OR DISRUPTING THE GASEOUS ATMOSPHERE, AND (C) VOLATILE OFF-ODOURS WHICH ACCUMULATE DURING STORAGE IN SEALED CO2-ENRICHED ATMOSPHERES GAS.
