PROBLEM TO BE SOLVED: To provide a nutritional composition that can be prepared with a low viscosity, the composition being semi-solidified (gelled) inside the stomach.SOLUTION: According to the present invention, there is provided a liquid nutritional composition prepared by mixing nutrients including proteins, lipids, carbohydrates, vitamins, minerals, and dietary fibers. Here, the liquid nutritional composition comprises 1 to 5% by mass of a protein degradation product based on the total amount of the liquid nutrition composition and 0.5 to 1.5% by weight of alginate based on the total amount of the liquid nutritional composition. The alginate has a viscosity of 20 to 200 mPa-s in a 1-mass% aqueous solution at 25°C. Furthermore, the composition has a heat quantity of 0.5 to 1.0 kcal/mL.SELECTED DRAWING: None【課題】低粘度で調製が可能な、胃内部で半固形化（ゲル化）させる栄養組成物を提供する。【解決手段】たんぱく質、脂質、糖質、ビタミン、ミネラル、および食物繊維を含む栄養素が配合されてなる液状栄養組成物であって、液状栄養組成物全量に対して１～５質量％の蛋白分解物を含み、液状栄養組成物全量に対して０．５～１．５質量％のアルギン酸塩を含み、前記アルギン酸塩の２５℃における粘度が、１質量％水溶液として２０～２００ｍＰａ・ｓであり、熱量が０．５～１．０ｋｃａｌ／ｍＬである、液状栄養組成物。【選択図】なし
