PURPOSE:To obtain a deodorized paprika pigment stable to oxygen, heat, light or the like and free of any foreign taste and odor by bringing paprika oleoresin into contact with carbon dioxide in a supercritlcal state in the presence of a polar solvent. CONSTITUTION:A deodorized paprika pigment is obtained by extracting paprika oleoresin with carbon dioxide in a supercritical state, for example, carbon dioxide at 20-40 deg.C and 70-250atm. for 1-30hr, desirably, 3-20hr in the presence of a polar solvent, for example, an alcohol (most desirably, ethanol). The amount of the polar solvent used is 1-20wt.%, desirably, 2-10%, based on the amount of the carbon dioxide used. According to this process, odorous components and free fatty acids can be selectively removed from the pigment, and the obtained paprika pigment does not adversely affect the flavor of a base when added to an edible fat or oil, butter, margarine or the like, and can be desirably used as a red oily colorant of excellent stability. |
