Physical, Chemical and Bioactive Properties of Four Different Pears (Pyrus communis L.) Varieties Grown in Turkey
Öz
In this study, physical, chemical and bioactive properties of four different pear varieties (Mellaçi, Mellaki, Deveci and Margarite) grown in Turkey's eastern regions were investigated. It was determined that the length, diameter and weight values of pear varieties varied between 6.08-9.56 cm, 5.42-8.30 cm and 92.27-254.95 g, respectively. Also, glucose, fructose and sucrose amounts of pear varied between 15.43-22.83, 18.08-30.62, 1.36-14.77 g 100 g-1 d.m (dried matter), respectively. TPC, ABTS and DPPH results of pear varieties were determined 622.56-3718.43 mg GA eq kg-1 d.m, 18.35-178.90 mmol Trolox eq/g d.m and 149.49-366.07 mmol Trolox eq/g d.m, respectively. Syringic acid, chlorogenic acid, ferulic acid, ellagic acid, catechin, epicatechin and rutin were detected in pear samples. Chlorogenic acid was the major phenolic component in pear varieties. Also, it was determined that significant differences were found among pear varieties in terms of physical, chemical and bioactive properties. While the Mellaki variety showed superior properties in terms of analyzed physical properties, the Margarite variety had superior properties in terms of chlorogenic acid and antioxidant activity.
