This invention becomes, the protein 30 - 100mg/ml and, including with the lipid 20 - 100mg/ml and the sugar 50 - 350mg/ml, at the same time the heat quantity of the composition is above 1kcal/ml, pH is 4 - 8, being the liquefied nutrition composition, hoeitanpaku which is included in the aforementioned protein, regards the liquefied nutrition composition which features that it is included at density above 8mg/ml vis-a-vis the whole composition. At the time of this inventing, the occasion where the liquefied nutrition composition is manufactured, it adds hoeitanpaku below the 55 and mixes, high temperature after sterilizing the compound liquid which is obtained, it converts homogeneously. According to this invention, the protein is included at density of the general nutrition food or density above that, at the same time, although ratio of hoeitanpaku in the protein is raised, it is possible to offer the liquefied nutrition composition which does not cause gelation and cohesion, etc possesses satisfactory thermal stability and physical properties.本発明は、タンパク質30~100mg/mlと、脂質20~100mg/mlと、糖質50~350mg/mlとを含んでなり、かつ組成物の熱量が1kcal/ml以上で、pHが4~8である、液状栄養組成物であって、前記タンパク質に含まれるホエイタンパク質が、組成物全体に対し8mg/ml以上の濃度で含まれることを特徴とする液状栄養組成物に関する。本発明においては、液状栄養組成物を調製する際に、ホエイタンパク質を55℃以下で添加し混合し、得られた調合液を高温殺菌した後に均質化する。本発明によれば、タンパク質を一般的な栄養食品の濃度もしくはそれ以上の濃度で含み、かつ、タンパク質中におけるホエイタンパク質の割合が高められている一方で、ゲル化や凝集などを起こさない、良好な熱安定性や物性を有する液状栄養組成物を提供することができる。
