(57) 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 DEG 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.
