| titleOfInvention | Recovery of phytosterols from residual vegetable oil streams |
| abstract | There is disclosed a method for isolation and purification of phytosterols from tall oil pitch comprising the steps of: a) contacting the tall oil pitch with a solvent to form a tall oil solvent mixture; b) separating the tall oil pitch solvent mixture in at least two separate streams wherein one process stream is enriched in acidic pitch components and a second stream enriched in free- and bound sterols in the form of steryl esters; c) subjecting the stream enriched in free- and steryl esters to treatment with an alcohol under transesterification conditions wherein a reaction mixture is formed and sterols comprising the steryl esters are liberated as free sterols; and d) separating the free sterols from the reaction mixture of step c) by crystallization and extraction with one or more solvents. There are disclosed free fatty acids and resin acids separated from the tall oil pitch. Moreover, there is disclosed a manufacture and separation of fatty acid alkyl esters by the method. |
