Abstract:

The aim of this work was to store fresh yellow plums (cvs. Sanacore and Ariddo di Core) for a maximum of 20 days at 1°C±1 and 90–95% relative humidity (RH) using modified atmosphere (MA) technology (flowpack system). Fruits of both cultivars were sealed in baskets with six films and compared with fruit stored under a normal atmosphere (NA). The effect of several packaging materials and several gas concentrations in modified atmosphere packaging (MAP) were evaluated on the postharvest quality of plums considering the weight loss, flesh texture, total soluble solids (TSS) and titratable acidity (TA). Samples were monitored at 0, 5, 10, 15 and 20 days. All continuous plastic films used have oxygen and carbon dioxide barriers that produce a passive atmosphere due to the interaction of fruit respiration and packaging films. The old Italian plum cultivars evaluated can be stored for a maximum of 10 days under NA conditions, and this period can be increased through different treatments under MAP conditions. In the present study, physical and chemical analyses demonstrated that the fruits of the Sanacore and Ariddo di Core plum cultivars can be successfully stored for 20 days using multilayer film (65 µm) with only slight changes in quality.
