Summary

A RETAIL PACKAGING SYSTEM WAS USED TO STUDY THE ATMOSPHERE MODIFICATION WHICH DEVELOPED WITHIN SEALED PACKAGES OF PREPARED BROCCOLI FLORETS WITH A RANGE OF POLYMER FILMS OF DIFFERENT GAS PERMEABILITIES (OXYGEN PERMEABILITY 0.34 TO 3.7 L/M2.SEC.PASCAL). THE EFFECTS OF THESE MA CONDITIONS ON SENSORY QUALITY WERE OBSERVED BY MONITORING COLOUR CHANGE AND DEVELOPMENT OF OFF-ODOURS. A 2-3% O2, 2-3% CO2 EQUILIBRIUM MA WAS ESTABLISHED AT 278 K (5 DEG C). THIS, THE ONLY CONSISTENTLY AEROBIC MA ATTAINED, DID NOT MARKEDLY IMPROVE RETENTION OF QUALITY OF BROCCOLI FLORETS. WHEN BROCCOLI FLORETS WERE PACKAGED WITH FILMS WHICH RESULTED IN VERY LOW O2 ATMOSPHERES (1% OR LESS) FOUL OFF-ODOURS SHORTENED BROCCOLI STORAGE LIFE.
