Bioactive Contents and Fruit Traits of Some Apple Cultivars Grown in Kayseri

Abstract

This study was carried out to determine the physical properties, biochemical and bioactive compounds of different apple cultivars grown in Yahyalı district of Kayseri province. The plant material of the research consisted of apple cvs. ‘Scarlet Spur’, ‘Starking Delicious’, ‘Starkrimson Delicious’, ‘Golden Delicious’, and ‘Super Chief’. In the study fruit weight, length, width, firmness, soluble solid contents (SSC), titratable acidity (TA), vitamin C, total phenolics, total flavonoids, and antioxidant activities (DPPH and FRAP assays) were investigated. In the findings, significant differences were determined between the fruit characteristics of the cultivars. The highest fruit weight (289.96 g) and length (32.61 mm) were measured from ‘Scarlet Spur’, while the highest fruit width (34.86 mm) was measured from ‘Scarlet Spur’ and ‘Starkrimson Delicious’. The SSC was determined between 11.65 (‘Super Chief’)-14.30% (‘Starkrimson Delicious’), and TA between 0.47% (‘Super Chief’)-1.13% (‘Golden Delicious’). The highest vitamin C content was measured in ‘Starking Delicious’ cultivar (66 mg100 g-1) compared to the others. In terms of total phenolic content, ‘Scarlet Spur’ (38.2 g GAE L-1) and ‘Super Chief’ (36.5 g GAE L-1) cultivars had the highest values, while ‘Super Chief’ had the highest values in terms of total flavonoids (23.5 g QE L-1), and antioxidant activity (FRAP, 490.7 mmol TE L-1; DPPH, 1145.9 mmol TE L-1). As a result, it was revealed the differences between the physical, biochemical, and bioactive contents of apple cultivars grown in Yahyalı district of Kayseri province.
