A method for selectively obtaining antioxidant rich aqueous extracts from the cells, frit, core, and peels of citrus fruits, comprises a) employing water treatment and solids extraction of the citrus fruit; b) employing separation technology and/or membrane technology on the extracts, resulting in a serum; c) submitting the serum to an adsorption process on resin, and d) eluting the adsorbed antioxidant compounds from the resin by solvents, preferably edible solvents such as ethanol or ethyl acetate, and collecting the solvent. For selectivity purposes, the solvent may be collected fraction-wise. The collected solvent fractions may be further evaporated to obtain dry phenolic compounds. |
