Abstract

The present study were carried out on"Anna" Apple fruits in two successive seasons 2008 and 2009 to study the effect of postharvest treatments CaCl2 dip for 2 min, O3 application in storage conditions of 4°C and 85-90% RH on fruit decay. It was found that ozone treated fruits had higher weight loss than that of the control. However, but the differences were not significant. Skin color improved as the anthocyanin pigment concentration increased, O3 treatment significantly changes fruit skin color. CaCl2 a treated fruit was the firmest and had the highest soluble solids content. Generally, fruit acidity decreased during storage period. O3 and CaCl2 treatments reduced decay in apple fruits.
