Abstract:
Five underutilized fruits from North Gujarat region viz. Karonda, bael, wood apple, jamun and fig were evaluated for their TS, TSS, titratable acidity, pH, ascorbic acid. Hydrophilic and lipophilic extracts were prepared from all the fruit pulp and analyzed for antioxidant activity and TPC content. The bael and karonda pulp showed higher TS and TSS content as compared to other fruits. The total phenolic and vitamin C content of bael pulp was highest as 14.16 µmol GAE/g and 65.32 mg/100g, respectively, while, karonda pulp also showed comparatively higher value of total phenolic content (7.88 µmol GAE/g) and vitamin C content (24.56 mg/100g) as compared to wood apple, jamun and fig. The antioxidant activity of hydrophilic and lipophilic extracts measured by ABTS and DPPH method was significantly (p<0.05) higher for bael and karonda. Further, the hydrophilic extract showed significantly (p<0.05) higher antioxidant activity as compared to lipophilic extract. Antioxidant activity showed a very high positive correlation with the TPC and Vitamin C content. Hence, it may be concluded that bael and karonda could be potent source of antioxidant components for the development of value-added dairy and food products.
