Provided is an acidic liquid nutritional composition that comprises protein, said protein containing 90 mass% or more of milk serum protein, lipid, saccharide, dietary fiber and 0.01-2.0 mass% of pectin. The acidic liquid nutritional composition according to the present invention has a high emulsion stability and shows little separation or sedimentation even in long-term storage. Thus, this composition can be stored over a long period of time (for several months). By increasing the protein content in the acidic liquid nutritional composition, a high-concentration and high-calorie acidic liquid nutritional composition having a good taste can be obtained.本發明提供一種酸性液狀營養組合物,其含有:包含90質量%以上之乳清蛋白之蛋白質、脂質、糖質、膳食纖維、及0.01~2.0質量%之果膠。本發明之酸性液狀營養組合物乳化穩定性高,即便供於長時間保管亦可抑制分離或沈澱,故而亦能夠長時間(數月時間)保存。藉由提高酸性液狀營養組合物中之蛋白質之含量,可獲得高濃度高卡路里之風味良好之酸性液狀營養組合物。無
