Summary

KAISER PEARS WERE HYDROCOOLED IMMEDIATELY AFTER HARVEST, OR AFTER A 6-DAY DELAY, AND CA STORED (AT 2-3% CO2 AND 4-5% O2). PITHY BROWN CORE WAS NOT EVIDENT AFTER COLD STORAGE, BUT IT REVEALED ITSELF AFTER 4 DAYS AT AN AMBIENT OF 297K (24 DEG C). DELAYED STORAGE INCREASED WEIGHT LOSS, SHRIVELLING AND BROWN CORE, BUT IT HAD A POSITIVE EFFECT ON EARLY HARVESTED FRUIT WHICH RIPENED COMPLETELY. HYDROCOOLING CONSIDERABLY REDUCES FRUIT DISORDERS, PARTICULARLY PEARS WHICH HAVE BEEN SUBJECTED TO DELAYED STORAGE, AND AT THE END OF THE STORAGE PERIOD HYDROCOOLED FRUIT SHOW HIGHER LEVELS OF TITRATABLE ACIDITY AND LOWER SOLUBLE SOLIDS, BUT THESE DIFFERENCES DISAPPEAR AFTER 4 DAYS AT AMBIENT TEMPERATURE. HYDROCOOLING DOES NOT AFFECT WEIGHT LOSS OR THE INCIDENCE OF ROT.
