  • METHOD FOR PRODUCING SUGAR FATTY ACID ESTER BY TRANSESTERIFICATION REACTION
    Publication number: 20210317154
    Abstract: The invention provides a method for producing a sugar fatty acid ester characterized in that a fatty acid ester and a saccharide are allowed to react and transesterified using a weakly basic ion exchanger having a pKb of 3 to 7 as a catalyst. According to the invention, problems with use of a strongly basic anion exchanger, that is, the decomposition of the product sugar fatty acid ester simultaneously proceeds, and the reaction is difficult to control, are resolved, and a sugar fatty acid ester can be efficiently produced.
