Abstract:
The pomegranate and their derivative parts contain various phenolic activities. The pomegranate peel had the highest antioxidant activity as compared to other parts of pomegranate fruit. It contains bioactive compounds such as Flavonoids, Polyphenols, Ellagitannins compounds (Gallic acid, Ellagic acid, Punicalagin, Punicalin, luteolin, Quercetin, kaempferol, glycosides, Pedunculagin), minerals (calcium, phosphorus, nitrogen, potassium, magnesium, sodium), and polysaccharide composite. In this study, the influence of different drying methods on the properties of two varieties (Bhagwa and Ganesh) of pomegranate peels was investigated. The pomegranate peel of both varieties was dried in a different method such as Freeze drying (-45 ºC for 94 hrs), Tray Oven drying (60 ºC for 29 hrs) and Sun drying (72 hrs). In this experiment used five different solvents such as methanol, ethanol, water, acetone, and hexane. In this study observed the freeze-dried sample of Ganesh pomegranate peel showed highest phenolic activity in the water, Flavonoid activity in ethanol and FRAP activity in methanolic extraction. The primary antioxidant (DPPH) activity was highest observed in GSD-A followed by GSD-M and GSD-E. The Bhagwa variety of pomegranate peel extract showed the highest phenolic and FRAP activity in the Methanolic extraction of freeze-dried and tray dried peel sample. The ethanolic extraction of Bhagwa tray dried peel showed highest flavonoid and antioxidant (DPPH) activity.
