ABSTRACT:
A process for producing a sucrose fatty acid polyester comprises reacting sucrose with fatty acid lower alcohol ester(s) in a solvent in the presence of an alkaline catalyst, wherein said fatty acid lower alcohol ester(s) are employed in an amount at least 5 times by mol as much as said sucrose. The alkaline catalyst component is removed from the reaction product thus obtained and the obtained sucrose fatty acid polyester-containing solution is catalytically treated with activated clay. This process enables the production of a sucrose fatty acid polyester containing an extremely small amount of ash components and having an extremely low color value. The alkaline catalyst used in this process may be recovered and reused, which further makes the process of the present invention advantageous.
