Antioxidant Activity and Total Phenolics of Local Apple Cultivars Encountered along the Coastal Zone of Northeastern Anatolia Region of Turkey

In this study, antioxidant activity and total phenolics in fruit flesh and fruit flesh + skin tissue of local apple cultivars encountered along the coastal zone of Northeastern Anatolia Region (Turkey) and 5 standard cultivars were determined. In local cultivars, antioxidant activities (μmol Trolox equivalent (TE) antioxidant g fresh weight (fw)-1) varied between 0.17-1.70 in fruit flesh and between 0.35-1.55 in fruit flesh + skin tissue; in standard cultivars, the values varied between 0.24 (‘Royal Gala’) and 0.29 (‘Granny Smith’ and ‘Pink Lady’) in fruit flesh and between 0.27 (‘Jonagold’) and 0.61 (‘Royal Gala’) in fruit flesh + skin tissue. In local cultivars, total phenolics (Gallic acid equivalent (GAE) kg fw-1) varied between 53.26- 00.54 in fruit flesh and between 89.32-406.91 in fruit flesh + skin tissue; the values in standard cultivars varied between 56.30 (‘Royal Gala’) and 124.64 (‘Jonagold’) in fruit flesh and between 102.73 (‘Summerred’) and 198.72 (‘Jonagold’) in fruit flesh + skin tissue. Present findings revealed that local cultivars generally had 3-4 times greater antioxidant activity and total phenolics than the standard cultivars. Fruit flesh + skin tissue generally had greater antioxidant activity and total phenolics than the fruit flesh alone. However, the local apple cultivar of ‘Hemşin Elması’ had greater values of both parameters in fruit flesh than in fruit flesh + skin tissue.
