ABSTRACT:
A chromatographic process for deacidification of vegetable oils at ambient temperature. According to the process, which can be retrofitted into deacidification operations using miscella refining or solvent extraction, crude vegetable oil is dissolved in a solvent such as isopropyl alcohol and passed through a column of activated alumina (aluminum oxide) at room temperature. The process, which eliminates physical contact between both oil and an alkaline reagent and oil and water, simplifies subsequent bleaching processes by also removing some color pigments. The spent alumina can be reactivated by washing it with a dilute solution of sodium hydroxide or potassium hydroxide.
