Abstract: The process for recovery of plant sterols and tocopherols from deodorization distillates formed during chemical or physical refining of vegetable oils consists of the following steps: free fatty acids are removed from the deodorization distillate by vacuum distillation or by continuation solvent saponification, after the removal of free fatty acids, the received material is reacted with an aromatic carboxylic acid anhydride at a temperature of 50-150° C., under reduced pressure, after the treatment with anhydride, tocopherols are removed from the mixture, and crystalline free sterols are recovered from the distillation residue containing sterol esters, di- and triglycerides by transesterification.

Abstract: Methods are disclosed for the preparation of conjugated linoleic acid from linoleic acid-containing starting material(s) by alkali isomerization in apolar solvents. According to one of the method variations, the apolar solvent is an apolar aprotic solvent and an alkali metal alcoholate is used as base. In the other method variation a long chain alcohol of 6-20 carbon atoms is used as solvent, an alkali metal hydroxide or an alkali earth metal hydroxide or an alkali metal alcoholate is used as base, and the isomerization is carried out at 100-170° C.
