Provided is an enteral nutrient which, although containing a soy protein as a protein source, does not cause a rapid increase in viscosity and inhomogeneity due to aggregation or thermal denaturation by heating for sterilization or formulation step and is thus stable, and shows a good taste without giving any sense of bitterness and coarseness on the throat inherent to soybean.
