|Abstract:||The present investigation entitled, "Studies on extending the shelf life of sapota (Manilkara achras (Mill.) Fosberg)" with six packaging treatments and two storage conditions was conducted in two sets of experiments with three replications in Factorial Completely Randomised Design. The packed sapota fruits cv. Kalipatti were stored at room temperature (31.67-36.85°C ; 22.57-34.97 % R.H.) and in low cost, low energy input cool chamber (20.24 to 21.57°C ; 91-95% R.H.) in March 1994. There was an increase followed by subsequent decrease in TSS, reducing sugar and total sugar content with rresponding decrease in acidity upon prolonged storage under both the storge conditions irrespective of packaging treatments. Total weight loss, rotting, fruit softening and fruit skin shrinkage increased with the subsequent increase in storage in all the packaging treatments and under both storage conditions. Fruits stored in cool chamber followed the same trend of physico-chemical changes but at a slower rate. The shelf life of unpacked sapota fruit was found to be hardly 5 days at room temperature, however, the fruit could be stored upto 9 days when it was packed in polyethylene bag (100 guage and 1.2 % vents) . The shelf life of sapota fruit when packed in polyethylene bag (100 guage and 1.2% vents) + CFB box and in polyethylene bag (100 guage and 1.2% vents ) was extended upto 13 and 15 days, respectively in cool chamber. Moreover, cool chamber has the added advantage of easy construction and low cost.|
