ABSTRACT:
This present invention pertains to a process for the synthesis of sucrose fatty acid esters by reacting sucrose and a purified specific fatty acid ester under substantially solvent free conditions in the presence of a transesterification stationary catalyst and mechanical emulsification. The process is continuous, yielding selected individual products of separated simple sucrose fatty acid esters of mono-, di-, tri- and polyesters while recycling the unwanted ester fractions, the unreacted sucrose and fatty acid ester.
