Summary

DETAILS ARE GIVEN OF RESULTS OF TRIALS MADE WITH GOLDEN DELICIOUS, GRANNY SMITH AND STARKING APPLES BOTH IN AIR AND CA STORAGE. THE TRIALS INVESTIGATED THE EFFECT OF RATE OF RECOOLING ON FRUIT WHICH HAD WARMED DURING THE PACKAGING PROCESS HAVING BEEN INITIALLY PRECOOLED AFTER HARVEST. SIGNIFICANT DELAYS IN RECOOLING AFFECTED FIRMNESS AND COLOUR WITH GOLDEN DELICIOUS AND GRANNY SMITH. THE EFFECT OF RATE OF COOLING AND ATTAINMENT OF CA CONDITIONS WAS ALSO INVESTIGATED. RATE OF COOLING AFFECTS FIRMNESS ONLY WHEN THERE IS A DELAY IN REACHING CA CONDITIONS, AND A PERIOD IN EXCESSOF 6 DAYS IS NOT RECOMMENDED. THE EFFECT ON COLOUR CHANGE WAS NOT APPARENT, NEITHER WAS THERE ANY CHANGE IN POSTHARVEST DISORDERS. FOR ALL FRUIT, THE COOLING RATE IMMEDIATELY AFTER HARVEST WAS OF PARAMOUNT IMPORTANCE, AND STARKING IN PARTICULAR SHOULD BE COOLED TO 272.5 K (-0.5 DEG C) WITHIN 12 DAYS TO AVOID LOSS OF FIRMNESS.
