Orange peel is a great source of bioactive compounds like phenolic and ascorbic acid (AA), which have high antioxidant capacity. New methodologies called attention for their extraction employing greener solvents, as natural deep eutectic solvents (NADES). There lack information about the protective role stability in NADES. This study aims to find most suitable NADES from orange peel. The first step was screening eight NADES, determining its capacity (AC), AA, total content (TPC) flavonoids...

The aim of this study was to optimize and compare four different natural deep eutectic solvents (NADES) for the extraction flavonoids in orange peels (Navel cultivar) from Valencia (Spain). Four NADES systems with two components were obtained their corresponding molar ratios. Three independent variables used optimization: solid-liquid ratio, time percentage water. results showed highest choline chloride: fructose (NADES-1) 50% water content, a solid–liquid ratio 1:25 23 min. demonstrate that...
