The Effect of hot Water Treatment and Polyethylene Bags Application on The Storage Life and Quality of Pomegranate (cv : Malas - Torsh)

This research work was carried out at Dept. of Horticulture, Univ. of Tehran, Karaj to find out how the qualitative and quantitative characteristics of pomegranate frutis could be improved in cold storage room. In this experiment the effects of hot water and the use of polyethylene bags on the quality improvement of pomegranate fruits during storage were studied. For this purpose the pomegranate fruits of Malas-Torsh cv. Were harvested at fully ripen stage and treated with hot water (55 oC for 1 to 2 minutes). Thereafter, each fruit was packed in polyethylene bags of 0.01 and 0.04 mm in thickness and stored in cold storage room with 5 oC and relative humidity of 85% for 3 months. The experiments were conducted with completely randomized desigh with 3 replicates. The characteristics like: weight lose, fruit seed weight percentage , fruit seeds weight, total soluble solid (TSS) , juice dried weight percentage, pH and titratable acidity (TA) and colour intensity were measured. Other characteristics such as fruits and seed appearance for marketability, taste and fungi contamination percentage points of views were also examined. The results indicated that polyethylene bags had significant effects on the preventing the weight lose, improving the appearance and marketability of fruits during the storage, while showing no effect on pH, TSS and dry matter of frutis. Also the fruits treated with 50 oC hot water showed significant improvement of quality where treatment with 55 oC hot water failed to show such effects. Finally the combinatins between polyethylene bag packaging and 50 oC hot water treaatment further increased the general quality of stored pomegranate fruits with minimum fungi infection.
