Abstract:

In this study, production of sour cherry pomace anthocyanin extracts with conventional and ultrasonic methods were investigated. Firstly, the appropriate amount of sample and solvent was determined by using 'solid-liquid extraction method' and in trials the rate of 1:15; sample-solvent (ethanol) was used. In the determination of extraction process conditions, trials were carried out in three different durations (20, 40, 60 minutes) and three different temperatures (40, 60, 80oC). Appropriate extraction conditions were determined as, 40oC and 40, 60 minutes. In obtained extracts, total anthocyanin, total phenolic, antioxidant capacity (ABTS), pH, total dry material, water soluble mater, titratable acidity and color values were compared. Consequently, it was determined that in terms of anthocyanin contents, extracts which were produced with ultrasonic technique at 40oC and 40 minutes have the highest anthocyanin contents. Also, it was detected that ultrasonic technique is superior in terms of antioxidant capacity, phenolic content, and color rates.
