Possible solution lays in the re-utilization of this biomaterial rich with health-promoting bioactive compounds, where rutin and ellagic acid occupy noteworthy interest due to their antioxidant and anti-inflammatory potential. Thus, this study aimed to examine the effect of natural deep eutectic solvents (NaDES) on the recovery of rutin and ellagic acid from waste material – black raspberry fruit pomace. Thirteen different NaDESs were used for the ultrasound-assisted extraction of rutin and ellagic acid from black raspberry pomace, and compared with conventional solvents. Obtaining the amount of 840.19 µg/g of rutin, and 516.72 µg/g of ellagic acid, the mixture composed of choline chloride and 1,2-propanediol proved to be the most efficient extraction agent among NaDESs. These results emphasize the potential of NaDES-based extraction as a promising and sustainable practice for the valorization of black raspberry pomace. application/pdf 770620 bytes Abstracts Book startpage: 105 endpage: 105 2024 Kuzmanović Nedeljković, Snežana Krgović, Nemanja Jovanović, Miloš Šavikin, Katarina Menković, Nebojša Živković, Jelena All rights reserved info:eu-repo/semantics/conferenceProceedings NATURAL DEEP EUTECTIC SOLVENTS EXTRACTION OF VALUABLE BIOACTIVE COMPOUNDS – SUCCESSFUL METHOD FOR VALORIZATION OF BLACK RASPBERRY (RUBUS OCCIDENTALIS L.)
