Abstract
A process for producing a food material having a high concentration of eriocitrin, which comprises extracting a juice, a peel and a squeezed juice refuse of a citrus fruit with a polar solvent, applying the extract to a synthetic adsorption resin, and separating and recovering the food material having the high concentration of eriocitrin using an organic solvent such as hydrous alcohol. A food material having a high concentration eriocitrin as an antioxidant ingredient can industrially be produced quite efficiently without entraining an ingredient of a bitter taste, and drink and food having a high antioxidant effect can be produced.
