Deacidification of Sucrose Fatty Acid Ester by Treatment with Ion Exchange Resins.

抄録

As one of the important problems in purifications of sucrose fatty acid ester, a new food-additive, its deacidification was investigated. The method of ion exchange in a non-aqueous medium was carried out, and it was concluded that the deacidification of sucrose ester was performed by treatment with anion exchange resin after treatment with cation exchange resin or inorganic acid. A small amount of water contained in the solvent was effective to accelerate the exchange reaction. Decoloration by the ion exchange resins was also observed.
