DERİN ÖTEKTİK ÇÖZÜCÜLERİN PORTAKAL KABUĞUNDAN BİYOAKTİF BİLEŞİKLERİN EKSTRAKSİYONUNA ETKİSİ.

This study was planned to create an alternative use for orange peel, which is one of the most important fruit wastes within the scope of waste utilization. In the study, firstly, orange peel extracts were prepared by ultrasonic assisted extraction using different types of deep eutectic solvents in the green solvent category that can be alternative to organic solvents and the bioactive compound contents of these extracts were evaluated. As a result, it was determined that deep eutectic solvents were statistically effective in providing the highest total flavonoid compound and antioxidant activity values. In addition, when the individual phenolic compound profile was examined, the most dominant component was hesperidin and the highest value was reached with choline chloride:glycerol (1:2) combination. In conclusion, it was determined that deep eutectic solvents can be an alternative to organic solvents in the extraction of phytochemical compounds from orange peel. [ABSTRACT FROM AUTHOR]
