Abstract: The suitability of zero energy cool chamber (ZECC) with various kinds of packaging materials for short term preservation of pear fruit was studied in Hisar (Haryana). Three commercial varieties (Patharnakh, Kashmirinakh and Baggugosha) of pear were examined under ZECC storage (23.2 ± 3°C and RH 90-95%) and at room temperature (32 ± 4°C and RH 70-75%). Fruits were packed in polyethylene (PE) bags of individual fruit packing (IFP) and 1 kg capacity bag (0.01 mm and 0.05 mm thickness) and control fruits were packed in corrugated fiber board boxes and analysis of fruits was done on alternate day up to 10 days of storage. There was continuous decrease in firmness and chlorophyll content of fruits irrespective of the packaging treatments. Individual packing of fruits in polyethylene bags of 0.01 mm and storage under ZECC proved to be most effective treatment in checking the physiological loss in weight (PLW) and Patharnakh showed lowest mean PLW than Kashmirinakh and Baggugosha. Whereas, carotenoid content of the fruits was not significantly affected by packaging treatments. Polyethylene 0.05 mm of IFP stored at ZECC showed maximum chlorophyll content in all varieties at par with PE 0.01mm of 1 kg bag at ZECC and PE 0.05 mm of 1 kg bag at room temperature as well as at ZECC. As a result, the trio varieties of pear packed in PE 0.01mm and 0.05 mm of individual fruit packing stored at ZECC effectively maintained shelf-life parameters compared to ambient conditions.
