Claims36
A process for producing plant stanol by hydrogenating plant sterol in an organic solvent at a hydrogen pressure of 1-200 bar in the presence of a hydrogenation catalyst on a support material characterised in that
- the support material comprises silicon (Si) and
- the process includes a step of pre-purifying the plant sterol before performing the hydrogenation.
