Abstract
A process is described for the preparation of polyglycerol fatty acid esters from a reaction mixture to which a metallic catalyst is added, as well as to a method for the purification of an intermediate synthesis product which contains excess fatty acid in addition to polyglycerol fatty acid esters. Compared with the prior art, a significantly improved yield and a higher process speed is obtained along with more economic use of raw materials, auxiliary materials, solvents and energy.
