  In order to provide a method for producing a sucrose fatty acid ester having high monoester selectivity, a method for producing a sucrose fatty acid ester includes: a step of preparing an aqueous solution containing sucrose and a basic catalyst; and a step of producing a sucrose fatty acid ester, by mixing the aqueous solution obtained in the aforementioned step, a fatty acid alkali metal salt and a melted fatty acid ester, and heating the mixture with stirring under reduced pressure, wherein the step of producing a sucrose fatty acid ester has an earlier step of removing water from the mixture, and a subsequent step of performing transesterification after the earlier step, and, in the subsequent step, heating is performed through microwave irradiation such that the temperature of the mixture is below the sucrose decomposition temperature.

  为了提供一种生产具有高单酯选择性的蔗糖脂肪酸酯的方法，一种生产蔗糖脂肪酸酯的方法包括：制备含有蔗糖和碱性催化剂的水溶液的步骤；和生产蔗糖脂肪酸酯的步骤，将上述步骤中得到的水溶液、脂肪酸碱金属盐和熔化的脂肪酸酯混合，并在减压下搅拌加热混合物，其中生产蔗糖脂肪酸酯的步骤包括从混合物中除去水分的前一步和在前一步之后进行酯交换反应的后一步，在后一步中，通过微波辐照进行加热，使混合物的温度低于蔗糖分解温度。
