Abstract

The contents of sterols and stanols in vegetable oils and mist oil were analyzed by gas chromatography using a capillary column. The total sterol contents showed high values of 0.67~0.89g/100g in corn oil, rice bran oil, red pepper seed oil and sesame oil. Mist oil, a byproduct of soybean oil manufacture, was a suitable raw material for the production of stanol since it showed high sterol content (10.2g/100g). In the hydrogenation of sterol contained in mist oil using Pd catalyst, the effects saponification of oil were examined. The conversion of sterol to stanol was improved by a factor of 4~5 through saponification of oil, compared to the reaction without saponification.
