摘要

Abstract "Purification of unrefined edible oils and fats with magnesium silicate and organic acids" The present invention relates to the method of purifying an unrefined edible oil or fat by contacting the unrefined edible oil or fat with at least one adsorbent material. at least one adsorbent material comprises magnesium silicate. Magnesium silicate may be used alone or in combination with other purification materials such as citric acid. Such a method provides improved removal of impurities such as phosphorus, soap, chlorophyll, metal and sterol glycoside containing compounds from unrefined edible oil or fat.
