PROBLEM TO BE SOLVED: To provide a liquid composition having satisfactory tube flowability and bacteriostatic properties while having a high calorific value, and further to provide a liquid nutritive composition which has high emulsion stability and preferably a low osmotic pressure and can be stored for a long period of time.SOLUTION: There is provided a liquid nutritive composition which contains a protein, a carbohydrate, an emulsifier, oils and fats, and water, wherein the blending amount of the protein (A) is 2 to 11 mass%, the blending amount of the carbohydrate (B) is 10 to 35 mass%, the total blending amount of the emulsifier (C) and the oils and fats is 1 to 13 mass%. The liquid nutritive composition comprises: at least collagen peptide and vegetable peptide having a weight average molecular weight of 1000 to 5000 as the protein (A) at least a decomposed product of starch having a number average molecular weight of 400 to 900 as the carbohydrate (B) at least (i) a polyglycerol fatty acid ester in which an average degree of polymerization of polyglycerol is 6 to 20 and the main fatty acid is oleic acid and/or myristic acid and (ii) a monoglyceride in which the main fatty acid is a saturated fatty acid having 12 to 22 carbon atoms as the emulsifier (C) and at least oils and fats having a melting point of -30°C to 45°C as the oils and fats (D), and has a pH of 2.0 to 5.0.COPYRIGHT: (C)2014,JPO&INPIT【課題】高熱量でありながら、良好なチューブ流動性と静菌性の機能を備えた液状組成物を提供する。さらには、乳化安定性が高く、好ましくは浸透圧が低い、長期保存が可能な液状栄養組成物を提供する。【解決手段】 蛋白質、糖質、乳化剤、油脂、及び水を含む液状栄養組成物であって、蛋白質(A)の配合量が2~11質量%、糖質(B)の配合量が10~35質量%、乳化剤(C)及び油脂(D)の配合量の合計が1~13質量%であり、蛋白質(A)として、コラーゲンペプチド、及び重量平均分子量が1000~5000の植物性ペプチドを少なくとも含有し、糖質(B)として、数平均分子量が400~900である澱粉分解物を少なくとも含有し、乳化剤(C)として、(i)ポリグリセリンの平均重合度が6~20であり且つ主たる脂肪酸がオレイン酸及び/又はミリスチン酸であるポリグリセリン脂肪酸エステル並びに(ii)主たる脂肪酸が炭素数12~22の飽和脂肪酸であるモノグリセリドを少なくとも含有し、油脂(D)として、融点が-30℃~45℃である油脂を少なくとも含有し、pHが2.0~5.0である液状栄養組成物。【選択図】なし
