Provided is a liquid food which can be fed through free fall and has a physiologically preferable viscous property compared with a liquid food having an extremely low viscosity. By the combined use of a thickener and an emulsifier, a nutritional composition, which sustains such a viscosity as facilitating the production thereof in the process from the blending of starting material to packaging and, after heating, shows a viscosity suitable for tube feeding through free fall, can be provided. By the combined use of a thickener, an emulsifier and a water-absorbing dietary fiber, furthermore, a nutritional composition, which sustains such a viscosity as facilitating the production thereof in the process from the blending of starting material to packaging and, after heating, shows a viscosity suitable for tube feeding through free fall, can be provided.本發明係提供一種流質食品，其藉由自然落下投予便可使用，且與黏度非常低之流質食品相比，具有生理學上更佳之黏性。本發明係提供一種營養組合物，其係藉由組合使用增黏劑與乳化劑，而於自原材料之調合直至填充至容器為止之步驟中維持容易製造之黏度，且於加熱處理後具有適於藉由自然落下之經管投予之黏度。又，本發明係提供一種營養組合物，其係藉由組合使用增黏劑、乳化劑及吸水性食物纖維，而於自原材料之調合直至填充至容器為止之步驟中維持容易製造之黏度，且於加熱處理後具有適於藉由自然落下之經管投予之黏度。
