<p>A single-step acid degumming/decolorizing process removes chlorophyll-type compounds from vegetable oils from seeds, especially frost damaged seeds which having large amounts of chlorophyll-type compounds. A mixture of aqueous sulfuric and phosphoric acids is blended with the oil to remove chlorophyll-type compounds from the oil. The purified oil has less than about 5 ppm chlorophyll-type compounds, less than about 50 ppm phosphorus and less than about 1.0 weight percent free fatty acids.</p> |
