Abstract
The aim of this study was to evaluate the effect of edible coating of chitosan solutions at different
concentrations (0, 0.5, 1, 1.5 and 2%) on the extend the overall quality stability and shelf-life of pomegranate arils
during cold storage at 4 ± 1 °C for 16 days. Physicochemical, microbiological and sensory quality attributes of the
arils were determined during storage. The results revealed a general trend; slightly changes were detected in total
titratable acidity, pH, total anthocyanin, total phenolic content and antioxidant activity values of all coated samples
compared with uncoated samples. Chitosan coating helped keeping the visual quality of arils during storage as
confirmed by their surface color measurement. Total Plate count as well as psychrophilic bacterial count and yeasts
and molds counts were increased with the increasing of cold storage period in all the treatments. The uses of edible
coating of chitosan solutions (1.5 and 2%) were more affective to preserve high quality and convenience of
pomegranate arils during storage at 4±1 °C for 16 days, with good chemical and microbiological qualities as well as
sensory attributes compared with uncoated samples.
