Abstract
Garden picked mature but unripe fresh persimmon fruits were unipackaged in different thicknesses of polyethylene (PE) and stored at room (18.5-30 degr eesC) and refrigerated temperature (6 +/- 1 degreesC). Maximum mean methano l extractable sinapine (0.168%), catechin (1.51%), and leucoanthocyanidine (10.94 Delta A550/g) were recorded in the unipackaged samples kept at room temperature during 6 weeks storage, whereas the minimum values for water ex tractable phenolics (sinapin, catechin and procyanidin) were recorded in un ipackaged samples under refrigerated temperature. The mean maximum weight l oss of 12.58 and 7.90% was recorded in control samples kept at room tempera ture and low temperature, respectively. The weight loss for unipackaged in different thicknesses of PE ranged between 0.93-0.96% and 0.43-0.45% for sa mples kept at room and low temperature, respectively. Changes in texture va lues were significantly faster in control than unipackaged samples (P < 0.0 5). Low temperature combined with unipackaging in PE film performed better for the maintenance of overall fruit quality during post-harvest storage.
