PROBLEM TO BE SOLVED: To provide a liquid nutritious composition which has refreshness brought by acidity, slightly-viscous and pleasantly-tasty refreshness, refreshing appearance due to transparency, and both of heat resistance and emulsification stability while containing nutrient components such as protein, sugar and oil and fat with good balance.SOLUTION: The liquid nutritious composition includes protein, sugar, an emulsifying agent, oil and fat and water, and has pH 3.0-5.0. In the liquid nutritious composition, the protein (A) is collagen peptide and vegetable peptide having a weight-average molecular weight of 1,000-5,000, the sugar (B) is sugar having a number-average molecular weight of 300-900, the emulsifying agent (C) is a polyglycerine fatty acid ester being an ester comprising polyglycerine having an average degree of polymerization of not less than 5 and either of an oleic acid or a myristic acid, the oil and fat (D) is MCT, the blending quantity of the protein (A) is 2-11 mass%, the blending quantity of the sugar (B) is 1-35 mass%, and the total blending quantity of the emulsifying agent (C) and the oil and fat (D) is 1-13 mass%.COPYRIGHT: (C)2012,JPO&INPIT【課題】 蛋白質、糖質、油脂などの栄養成分をバランスよく含みながら、酸味による爽やかさがあり、粘度が低く飲みくちの良い爽やかさがあり、透明感によって見た目にも爽やかな、更には耐熱性と乳化安定性も併せ持つ酸性液状栄養組成物を提供すること。【解決手段】 蛋白質、糖質、乳化剤、油脂、及び水を含むpHが3.0~5.0の液状栄養組成物であって、蛋白質(A)が、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、糖質(B)が、数平均分子量が300~900の糖質、乳化剤(C)が、平均重合度が5以上のポリグリセリンと、オレイン酸またはミリスチン酸のいずれかとのエステルであるポリグリセリン脂肪酸エステル、油脂(D)が、MCT、を含有し、蛋白質(A)の配合量が2~11質量%、糖質(B)の配合量が1~35質量%、乳化剤(C)と油脂(D)の配合量の合計が1~13質量%である経口用液状栄養組成物。【選択図】 なし
