A process for the synthesis and isolation of phytosterol esters is
described, wherein an alkali metal borohydride is used to reductively
bleach tocoquinones and other chromophores in phytosterol ester
trans-esterification reaction mixtures. Phytosterol esters produced by
this method possess the traditional hallmarks of quality, namely bland
taste and light color, and are suitable for food and pharmaceutical
applications.
