Abstract
The invention relates to a process for the preparation of stanol esters by hydrogenating a sterol blend in a hydrogenation solvent and at an elevated temperature in the presence of a hydrogenation catalyst, by removing the hydrogenation catalyst from the obtained hot reaction solution, by transesterifying the intermediate stanol blend with a fatty acid methyl ester at an elevated temperature and in the presence of a transesterification catalyst, and by finally purifying the stanol ester blend thus obtained. According to the invention, the intermediate stanol blend is neither crystallized nor removed from the reaction solution but the hydrogenation solvent is replaced therein at least in part by a transesterification reagent. Alternatively, the hydrogenation solvent may also be used as the transesterification solvent, and preferably also as the transesterification reagent.
