POST-HARVEST TECHNOLOGIES INFLUENCES IN ORGANIC 'TITA' PLUMS QUALITY

The paper aims to present the influences of post-harvest technologies on organic 'Tim' plums during storage period taking in consideration the variation of quality indicators, physiological parameters, and bioactive compounds. Organic 'Tita' plums were harvested in 2019, at the end of July and stored in three different condition. i.e.: 1) normal atmosphere (NA) with 1 degrees C and 95% relative humidity (RIO, 2) controlled atmosphere (CA) conditions with 1 degrees C, 95% RH. 3% O-2 and 5% CO2 , and 3) CA conditions with 1 degrees C, 95% RH. 1.5% O-2 , and 10% CO2. Organic plum samples were evaluated at 4 moments: initially (before storage), after 3, 5, and 7 weeks of storage. Obtained results showed that total phenolic content and antioxidant activity registered the same variation trend during storage period for all samples. Differences were observed during storage period which was shorter with 2 weeks for plums stored in NA than for those stored in both controlled conditions. Taking into consideration these results, present work suggests that plums stored in both controlled atmosphere conditions were better preserved than those stored in NA. but further trials and studies are required.
