An object of the present invention is to provide a concentrated liquid food that enables easy injection and suppresses gastro-esophageal reflux.The object can be solved by a concentrated liquid food, comprising:(A) a polysaccharide that becomes gelated or thickened by combining with calcium；(B) a calcium source； optional (C) a chelating agent；(D) a protein having emulsifiabilty； and(E) a soybean hemicellulose,(with the proviso that, when the calcium source (B) is a water-soluble calcium source, the concentrated liquid food comprises the chelating agent (C)),wherein the concentrated liquid food has a viscosity of 250 mPa·s or less before contact with a simulated gastric fluid, and has a viscosity of 1,500 mPa·s or more after contact with a simulated gastric fluid.
