Effects of cold storage on quality parameters and nutraceutical compounds of pomegranate fruits (cv. Acco)

Punica granatum L. contains several bioactive compounds with antioxidant activity that have a positive effect on human health. This study aims to investigate the changes in chemical-physical and qualitative parameters of pomegranate fruits cv. Acco from harvest up +90 days cold storage (+4°C 95% RH). Morphological parameters, juice yield, weight loss, total soluble solids content (TSS), pH, titratable acidity, color epicarp (L*, a*, b*), polyphenols, anthocyanins, flavonoids, were analyzed. The results showed an increase (about 29%) (%) at +60 storage. Cold has also shown effects some compounds. Flavonoids anthocyanins 287.98 mg CE/100 ml 389.23 8.32 mg/100 11.13 + 90 storage, respectively. On basis our confirmed literature data, fruit is rich exert beneficial actions health, it been demonstrated such nutraceutical increased during allowing be preserved long term.
