ABSTRACT:
The invention relates to a process for the solvent-free preparation of sucrose fatty acid esters, their mixtures with nonsugar polyol fatty acid esters, and in particular of sucrose glycerides. In a first process step, sucrose is reacted with fatty acid alkyl esters in the presence of basic catalyst at reduce pressure and elevated temperature. In a further reaction step, the reaction mixture obtained above is reacted at reduced pressure and elevated temperature with 0.1 to 0.5 mol of polyol per mole of fatty acid alkyl ester employed and then filtered. The products of the process according to the invention have very high sucrose ester contents. They are free of undesired, unreacted alkyl ester.
