Abstract
To determined chemical and physical properties for pomegranate fruits (cv. ‘Salakhani’)
over postharvest treatment with three Salicylic acid (SA) concentrations (0, 2 and 4 mM) and
four storage periods (25, 50, 75 and 100 days) at 2-3°C with 85-95% relative humidity, fresh
pomegranate juice of every treatment was evaluate for TSS, TTA, TSS/TTA, Total sugar,
Anthocyanin, Vit. C, pH and Juice percentage. Fruit physical disorder such as weight loss,
chilling injury, chilling injury index, decay, scald, aril and peel moisture content were also
investigated after each treatment.
The results showed that the TSS, TSS/TTA ratio, Total sugar, Anthocyanin and Vit. C
increased significantly (p<0.05) throughout the treatment 2mM SA, however, the pH value for
complete fruit increased as a result of TTA (1.02 %) decreasing, despite the change within the
chemical properties of the juice, the percentage of juice didn’t differ significantly after
treatment fruits with (2 and 4mM) SA compared to the control, for decreasing weight loss,
chilling injury, chilling injury index, decay and scald 4 mM SA was more affective comparing
to control.
The results showed that most of chemical and physical disorder properties increased during
storage with increasing storage duration exception of peel moisture content.
The interaction between treatments with different concentrations of SA then storage fruits for
various periods led to the improvement of these characteristics, especially the concentration 2
mM and storage periods 25 and 50 days. Contrariwise, there have been decreases in (TTA)
throughout the storage duration 100 day at 4 mM SA.
Furthermore, aril and peel moisture content significantly change at majority of the storage
period 100day and 4 mM SA
