Abstract
Sterols are separated from fatty materials containing a substantial amount of sterol material by saponifying the fatty material in a methanolic alkaline medium, acidulating the resulting saponified mixture to convert the resulting soaps to free acids, e.g. with sulphuric acid, separating the resulting glycerol-containing aqueous phase and a sterol containing phase, dissolving the sterol-containing phase at a raised temperature in a methanolic solvent medium, cooling the resulting solution to a temperature from 0 DEG C. to 20 DEG C. to selectively crystallise sterols therefrom, and separating the crystallised sterols. The methanolic solvent medium may consist of 9%-100% by volume of methanol, 0%-90% of acetone or methyl ethyl ketone, and 0%-10% by volume of water. Materials which may be used in the above process are deodorizer sludges, e.g., derived from vegetable oils such as soybean oil, cottonseed oil, corn oil and safflower oil, fatty acid distillation residues, and still bottoms such as tall oil still bottoms and soap stocks.
