摘要
The invention describes a global method for extracting sterols, vitamin E, squalene and other vegetable hydrocarbons from deodorization distillates of vegetable oils. After esterification of the free fatty acids, followed by trans-esterification of the combined fatty acids (glycerides and sterides) with the same short alcohol, three successive distillations allow successive recovery of a first fraction of the hydrocarbons, the main fraction of alkyl esters, and then the heaviest alkyl esters with squalene. The third distillate will be used for producing squalene and a second fraction of hydrocarbons. The residue of the third distillation will be used for producing sterols and vitamin E. By using bio-ethanol, vegetable glycerol and the vegetable hydrocarbons of the method, with the method it is possible to extract each of the four unsaponifiables without any solvent of petroleum origin and claim the labels of products obtained by natural physical and chemical methods.
