Summary

TREATMENT OF MCINTOSH APPLES WITH 10, 20 OR 30% CO2 FOR 2, 4, 7, 14 AND 21 DAYS PREVIOUSLY TO STORAGE IN 5% CO2 + 3% O2 CAUSED A CONSIDERABLE CO2 PEEL INJURY AND ONLY SLIGHTLY INHIBITED FLESH FIRMNESS LOSSES DURING STORAGE AT 275.5 K (2.5 DEG C). TREATMENT FOR 24 HOURS, ONCE OR EVERY 2OR 4 WEEKS WITH 10 OR 30% CO2 BEFORE STORAGE IN AIR DID NOT DELAY SOFTENING AND DID NOT SHOW CO2 PEEL OR FLESH INJURY ; HOWEVER APPLES WERE LOOSING THEIR FLESH FIRMNESS SOMEWHAT SLOWER AT 293 K (20 DEG C). TREATMENT WITH50% CO2 FOR 12 HOURS AND WITH PURE NITROGEN FOR 48 HOURS BEFORE STORAGE IN AIR RESULTED IN A STATISTICALLY SIGNIFICANT INHIBITION OF FLESH SOFTENING AT 275.5 K, BUT NOT AT 293 K. THE HIGHEST RIPENING INHIBITION AND THE HIGHEST FIRMNESS WERE OBTAINED AFTER STORAGE IN 2% CO2 + 1.5% O2 AND IN 0% CO2 + 1.5% O2. APPLES STORED IN 5% CO2 + 16% O2 WERE FIRMER THAN THOSE FROM A REGULAR ATMOSPHERE.
