いる。[Detailed Description of the Invention] [Prior Art] Sugar alcohol fatty acid esters, especially sucrose fatty acid esters, are used in large quantities as emulsifiers for foods.
The manufacturing method is known as the solvent method. For example, a reaction method using a solvent such as dimethyl sulfoxide or dimethylformamide, a microemulsion method using propylene glycol as a solvent for sucrose, and a method in which sucrose, fatty acid ester, and soap are added and heated without using a solvent. There is a solventless method (direct method) in which the material is melted and reacted at 130 to 180°C. Since all of these methods use potassium hydroxide, sodium hydroxide, potassium carbonate, sodium carbonate, potassium carbonate, etc. as catalysts, soap is included in the reactants. In particular, %Wt medium method (direct method)
Since a large amount of soap is used in this process, the reaction product usually contains 10 to 40% soap. Various methods have been used to remove this soap (for example, as in Jikai, 62-212593, after the reaction, hydrochloric acid is added to the reactant to decompose the soap and turn it into fatty acids, which is then removed by molecular distillation). .

石鹸分を除去出来る事を発見し、本発明を完成した。[Objective of the present invention] The inventor of the present invention has prepared a reaction product obtained by a solvent-free method (direct method) or a microemulsion method into a sugar alcohol fatty acid ester (e.g., sucrose fatty acid ester, maltitol fatty acid ester, mannitol fatty acid ester, lactitol fatty acid ester, sorbitol fatty acid ester), and does not dissolve the soaps contained in the reaction product, such as sodium, potassium, lithium, etc., or does not dissolve them easily, such as hexane, cyclohexane, heptane, octane. , isooctane, benzene, xylene, toluene, etc., or a mixture thereof, and then ultrafiltered with an ultrafiltration membrane with a molecular weight cutoff of 2.000~too, ooo, to achieve extremely high efficiency. He discovered that soap can be removed and completed the present invention.

Examples include, but are not limited to, poly(ether) sulfone and acetyl cellulose. The exclusion limit molecular weight of the membrane is in the range of 2.000 to 5,000, preferably 5.
