A Research on the Phenolic Composition of Apple Juice

Öz

Fourty-five apple juice samples were produced from 3 different apple cultivars from f ı ve apple growing regions in three consecutive crop years and analysed for their phenolic composition. The main phenolic compound of apple juices was chlorogenic acid ranged from 62.3 to 342.6 mg/I. It was followed by epicatechin, phloretin glycoside, phloridzin and p-coumaric acid to be at levels 5.3-240.1 mg/I, 5.5-60 mg/I, 6.9-29.7 mg/I, 1.1-16 mg/I, respectively. Cultivar and crop years signifı cantly affected phenolic composition of apple juice, while growing region did not have a significant effect.
