This investigation was conducted on cactus pear fruits (Opuntia ficus-indica L. Mill) in two successive seasons 2007 and 2008 with the objective of studying the effect of post-harvest treatments i.e., hot water dip at 55°C for 2 min, wax application and film wrapping using both low density polyethylene (LDPE) and high density polyethylene (HDPE) in storage conditions of 10°C and 85.90% relative humidity (R.H.). The results of the aforementioned treatments were as follows:There were marked changes in weight loss, TSS. %, titratable acidity, Ascorbic acid and carotenoid content, given that hot water dip treatments and wax application showed an increase in vitamin C content of the fruits and carotenoid. Furthemore, the loss in weight and amounts of vitamin C and TSS.% could be increased during storage, while acidity and carotenoid content were decreased.
