摘要： A process is provided which allows the isolation of sterols and a tocopherol concentrate in high yields from a deodorizer distillate (DOD) mixture obtained from the processing of, for example, soybean oils. Treatment of DOD with methanol at preferably 200.degree.-220.degree. C. in the presence of a monoalkyl- or dialkyl-tin compound results in the conversion of fatty acids and fatty acid esters into fatty acid methyl esters (FAME) and the liberation of free sterols and glycerin without appreciable degradation of tocopherols or sterols. The process can also be carried out in two steps where glycerin is used in the initial step and the fatty acids are converted into glycerides allowing the water of reaction to be removed as it is formed. The FAME produced by both methods are removed by a stripping operation to give a concentrate that allows the isolation of sterols in high yield and high purity and the isolation of a tocopherol concentrate by molecular distillation.
