ABSTRACT:
A process for purifying olive oil which includes neutralizing the oil with an amount of a saturated aqueous solution of crystalline disodium carbonate equivalent to two to ten times the weight of oleic acid in the oil calculated after assay; allowing the aqueous phase to separate and washing the oil until the oil is substantially neutral; and drying the oil and decolorizing the oil using a bleaching earth under an inert atmosphere.
