Özet

In this research, the effects of different postharvest applications as 1-methylcyclopropane (1-MCP), sucrose polyesters of fatty acids and different modified amosphere packaging types based low density polyethylene (LDPE), polyvinylchloride (PVC) on fruit quality of 'Angeleno' plums were evaluated. For this purpose, fruits harvested from Canakkale province were treated with 1-MCP (Smartfresh (TM)) and coating material including sucrose polyester (Semperfresh (TM)). In addition other groups of fruits were packaged with LDPE and PVC shrink film. These 4 group of fruits with control fruits that were untreated and unpackaged were stored at 0-1 degrees C and 85-90% RH for 30, 60, 90 and 120 days respectively. After each storage period fruits were kept at 18-22 degrees C for 3 days as shelf life. After harvest and each storage period, some quality parameters as weight loss, fruit firmness, soluble solids content, titratable acidity and fruit flesh color brightness were measured. Furthermore, the rate of internal breakdown was determined. According to the results, both of the applications had positive effects on the quality parameters after each storage period. Furthermore, modified atmosphere packaging based LDPE and sucrose polyester (Semperfresh (TM)) applications had clear effects.
