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.本發明之目的係在於提供乳化食品組成物，其即便供至加熱殺菌處理亦具備良好的流動性及乳化安定性，且藉由進入胃內則會膠化而可防止胃食道之逆流。在含有脂質的乳化食品組成物中，藉由將在酸性區域會膠化的增黏劑、選自於由阿拉伯膠及哥地膠所構成群組中之至少1種乳化安定劑及2價金屬鹽一起摻合，可在具備進入胃內即會膠化之特性的同時，即使供予加熱殺菌處理，仍可使流動性及乳化安定性良好。
