    摘要: By using ion exchange column chromatography or calcium carbonate to an aqueous solution containing a compound A represented by the following formula and citric acid, citric acid in the aqueous solution is removed and a crystalline compound A is obtained by being thereafter subjected to several steps. Further a high-purity noncrystalline compound A is obtained by using calcium carbonate, sulfuric acid, an organic solvent and the like to the aqueous solution containing the compound A and citric acid to remove citric acid and the crystalline compound A in the solution. The configuration of the crystalline compound A is an SS isomer in the RS notation system. The configuration of the noncrystalline compound A is an SR isomer.

    摘要: The purpose of the present invention is to provide an emulsified food product composition having good fluidity and emulsification stability, even when subjected to heat sterilization treatment, with which gastro-esophageal reflux can be prevented by gelling upon entering the stomach. By adding a gelling agent for gelling in the acidic region, at least one emulsion stabilizer selected from the group consisting of gum arabic and gum ghatti, and a divalent metal salt to the emulsified food product composition comprising a lipid, it is possible to realize the property of gelling upon entering the stomach and obtain good fluidity and emulsification stability, even if a heat sterilization treatment is used.
