Sažetak
Cyclodextrin enhanced pulsed ultrasound assisted extraction (UAE) procedure was developed for obtaining olive pomace (OP) extract rich in bioactive polyphenols, principally oleuropein, tyrosol, and hydroxytyrosol. 20-minute extraction using 12 mm probe at 100% output intensity was selected as optimal for the extraction of OP polyphenols using 60% EtOH at 1:40 solvent to solid ratio. Addition of cyclodextrins (CDs) to extraction solvent (especially randomly-methylated beta CD and hydroxypropyl-beta-CD) improved extraction yields and stability and the appearance (colour and particle size distribution) of obtained extracts was also significantly affected. Extracts obtained under optimized conditions contained 886.46 mgkg-1 of hydroxytyrosol, 1117.02 mgkg-1 of tyrosol and 1744.37 mgkg-1 of oleuropein. In comparison to conventional solvent extraction, application of UAE resulted in significantly higher yields reduced extraction time and solvent consumption.
