Abstract: 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.

Abstract: A method of obtaining a natural super-cloud composition of citrus components, which method entails: (a) extracting with water at a temperature of about 60-100° C. at least one citrus constituent comprising peel, core, cells, frit or juice or a combination thereof, to obtain water-extracted soluble citrus solids; (b) separating the water-extracted soluble citrus solids and discarding high mesh material, to obtain a liquor consisting essentially of low sedimented pulp; (c) enzymatically treating said liquor with pectolytic enzymes; (d) inactivating natural and added enzymes in the liquor; (e) centrifuging said liquor by hot centrifugation; (f) concentrating the centrifuged liquor; and (g) subjecting the concentrated liquor to membrane separation, wherein the membrane cut-offs are 30,000-500,000 molecular weight, and obtaining a retentate containing the super-cloud composition.
