Abstract
The method of purifying an unrefined edible oil or fat by contacting the unrefined edible oil or fat with at least one adsorbent material. The at least one adsorbent material comprises magnesium silicate. The magnesium silicate may be used alone or in combination with other purifying materials, such as citric acid. Such method provides for improved removal of impurities, such as phosphorus-containing compounds, soap, chlorophyll, metals, and sterol glucosides from the unrefined edible oil or fat.
