Sugar and Biochemical Composition of Some Apple Cultivar Grown in the Middle Black Sea Region

Changes in ecological conditions Turkey are among the rare countries where most plant species spread widely throughout country, both economically and naturally. In this study on apple, which is one of important fruit with economic importance, color characteristics, biochemical sugar contents some commercial apple cultivars grown Çarşamba district Samsun province were examined. Wide variations occurred all parameters evaluated cultivars. The fructose content was from 14.22 (Royal Gala) to 34.40 g 100 ml-1 (Fuji), glucose 1.30 (Galaxy 4.34 sucrose varied 2.01 (Fuji) 4.52 (Granny Smith). highest value total determined Fuji cultivar 40.75 ml-1. phenolics, flavonoids antioxidant activity (according DPPH FRAP) 423.7 mg g-1 Smith), 96.1 250.8 µmol Smith) 952.9 respectively. principal component analysis results, first associated a*, b*, hue angle, (DPPH explained 59.4% variation. second 36.4% variation obtained data be related L*, chroma, glucose, sucrose, fructose, properties. As a result, Granny Smith gave remarkable results terms properties content. It thought that may guide researches made about region.
