METHOD FOR PRODUCING SUCROSE FATTY ACID ESTER

摘要

[Problem] To provide a method for producing a sucrose fatty acid ester having high monoester selectivity. [Solution] The method for producing a sucrose fatty acid ester according to the present invention is provided with a step for preparing an aqueous solution including sucrose and a basic catalyst, and a step for generating a sucrose fatty acid ester by mixing the aqueous solution obtained in the aforementioned step, an alkali metal salt of a fatty acid, and a molten fatty acid ester, stirring the mixture under reduced pressure, and heating the mixture. The step for generating the sucrose fatty acid ester has a front-stage step for removing water from the mixture, and a back-stage step for performing transesterification after the front-stage step, and in the back-stage step, the mixture is heated by irradiation with microwaves to a temperature less than the decomposition temperature of sucrose.
