Summary

CA INFILTRATION INTO THE FLESH OF MATURE APPLES (MALUS DOMESTICA BORKH.) FROM A POSTHARVEST DIP WAS ENHANCED BY INCREASING THE CACL2 CONCENTRATION, DECREASING THE TEMPERATURE AND SURFACE TENSION OF THE COOLING SOLUTION, INCREASING THE INITIAL FRUIT TEMPERATURE, AND INCREASING THE SUBMERSION DURATION. INCREASES OF FRUIT CA TO LEVELS NORMALLY ADEQUATE TO CONTROL STORAGE DISORDERS WERE ACHIEVED BY COOLING FRUIT AT 294 K (21C) FOR 10 MINUTES IN 4% CACL2 + 0.1% SURFACTANT L-77 AT 272 K (-1C). THE RESULTS SUGGEST THAT HYDROCOOLING APPLES WITH A REFRIGERATED CACL2 SOLUTION WOULD OFFER A PRACTICAL MEANS OF POSTHARVEST CA ENRICHMENT.
