Abstract

In
this study, total phenolic content, antioxidant capacity, total anthocyanin
content and total ascorbic acid content (in flesh+peel) of the 7 apple
cultivars grown in Posof/Ardahan were measured. The total phenolic content of
the three apple cultivars was higher than other cultivars. “Posofkırmızısı”, “Sarı
şafran” and “Paşa” apple cultivars had the highest total phenolic ccontents (239.22,
228.81 and 222.71 mg of gallic acid equivalents/100 g offlesh+peels,
respectively). Results showed that fresh apple had the highest levels for
antioxidant capacity (90.32 and 114.23 µmol of vitamin C equivalents/g of
flesh+peel) and total anthocyanin content (30.07 to 71.49 mg/100g), whereas
lower levels were found for ascorbic acid in flesh+peels. Results covered a narrow
range: 17.18–26.83 mg/100g for ascorbic acid content in flesh+peels weight of
apple cultivars. As a result, that these apple cultivars have high total
phenolic value and antioxidant capacity in flesh+peels. For this reason, it is
suggested for consume with their peels.
