Determination of Phytochemical Characteristics of Some Apple and Pear Cultivars

45072

This study was carried out in 2017 and 2018 with the aim of characterize some apple and pear varieties in terms of phytochemical characteristics. As a result of the study, when the average values of cultivars belong to species were examined, it was found that the properties of titreable acidity (TA), Vitamin C, total phenol and antioxidant activity (AOA) were higher in apple, while soluble solid content (SSC) and pH values were higher in pear. In apples, TA, Vitamin C, total phenol, AOA, SSC and pH values were determined in the range of %1.35 - % 0.34, 5.63 – 2.41 mg/100 mL, 494.8 – 158.68 mg/L, %78.23 – %55.94, %12.93 – %10.65, 3.73 – 3.00 respectively. In pears, these values varied between %0.5 – 0.13, 5.77 – 1.52 mg/100 mL, 334.76 – 103.49 mg/L, %78.43 – %11.93, %15.78 – %11.78, 4.87 – 3.47. It was detected that, total phenolic content, vitamin C and antioxidant activity was increased corresponding to increasing of the acidity in both species. In addition, as a consequence of the corelation analysis, antioxidant acitivity increased by rising of total phenolics and vitamin C content. It was found that ‘Jersey Mac’ was superior than the other apple cultivars in terms of investigated features, and early harvested cultivars had better phytochemical features, generally. ‘Limon’, ‘Santa Maria’, ‘Conference’ and ‘Moonglow’ cultivars were came into prominence among pear varieties. It was thought that, the data obtained from the study can lead the selection of parents in breeding programes and consumer preferences.
