<p>The invention relates to a novel process for obtaining tocopherols and sterols from natural sources, in particular plant sources. In particular, this process is a process for separating tocopherols and sterols from vapour condenser fats by distillation of these vapour condenser fats by esterifying the sterols present in the vapour condenser fat with the likewise present fatty acids before distillation, distilling the resulting mixture for the purpose of recovering residual fatty acids and subsequently for the purpose of recovering tocopherols, the sterol esters formed during the esterification remaining in the residue of this distillation, and then isolating the tocopherols from the distillate and the sterols, after cleavage of their esters, from the distillation residue.</p> |
