Abstract :In the present study, waste by-products of one of the popular fruit juices in the World has been valorized for its high-added value ingredients. Peels of sour cherry insert ignore into journalissuearticles values(Prunus cerasus L.); have been extracted by means of deep eutectic solvent insert ignore into journalissuearticles values(DES);-based microwave-assisted extraction insert ignore into journalissuearticles values(MAE);. DES system contained citric acid as hydrogen bond acceptor insert ignore into journalissuearticles values(HBA); and ethylene glycol as hydrogen bond donor insert ignore into journalissuearticles values(HBD); insert ignore into journalissuearticles values(1/4, molar ratio);. In order to optimize the MAE system Central Composite design insert ignore into journalissuearticles values(CCD); of Response Surface Method insert ignore into journalissuearticles values(RSM); has been used. The measured variables were the yields of total phenolic insert ignore into journalissuearticles values(TPC);, total anthocyanins insert ignore into journalissuearticles values(TA); and cyanidin-3-glucoside. Optimum conditions were determined as 0.1 g of peel and 50 % insert ignore into journalissuearticles values(v/v); water contribution to the DES for the maximum reovery of TPC insert ignore into journalissuearticles values(16.85 mg-GAE/g-FP);, TA insert ignore into journalissuearticles values(3.39 mg-cyn-3-glu/g-FP); and cyanidin-3-glucoside insert ignore into journalissuearticles values(mg/g-FP); in the MAE of sour cherry peels. The relationship between the responses was also established.
