A liquid food composition that can be conveniently ingested or given with a tube and contains reduced aggregates in the composition is provided. A liquid food composition that shows fluidity in the neutral region, but solidifies in the stomach environment is further provided. According to the production method of the present invention, generation of fine particles in the production process of a liquid food composition containing a divalent metal salt, a protein, and water-soluble dietary fibers is reduced. Therefore, emulsification stability of the composition is improved, clogging of aggregates in strainer disposed in the production line etc. are eliminated, and thus the composition can be efficiently produced. Furthermore, since the composition obtained by the production method shows fluidity in the neutral region, but solidifies in the stomach environment, it can be conveniently ingested or given with a tube, and can effectively reduce the risks for developing gastroesophageal reflux disease, aspiration pneumonia, diarrhea, etc.
