Summary

THE AUTHORS STUDY THE ATMOSPHERE MODIFICATION WHICH DEVELOPED WITHIN PACKAGES OF SHREDDED ICEBERG LETTUCE, SEALED IN TRAYS WITH POLYMER FILMS OF DIFFERENT GAS PERMEABILITIES. MODIFIED ATMOSPHERES WERE PRODUCED BOTH NATURALLY BY RESPIRATION, AND BY APPLICATION OF GAS FLUSHING TECHNIQUES. THE EFFECTS OF THESE MODIFIED ATMOSPHERE CONDITIONS ON VISUAL AND SENSORY QUALITY WAS OBSERVED BY MONITORING COLOUR CHANGE AND DEVELOPMENT OF OFF-ODOURS. AN ATMOSPHERE CONTAINING 1-3% O2 AND 5-6% CO2 WAS ESTABLISHED WITH 35 MICROMETER LOW DENSITY POLYETHYLENE FILM AFTER FLUSHING WITH 5% O2, 5% CO2 IN N2. THIS RESULTED IN A SHELF LIFE OF APPROXIMATELY 14 DAYS AT 278 K (5 DEG C), ALMOST DOUBLE THAT OF THE CONTROLS.
