PROBLEM TO BE SOLVED: To provide a thickener for liquid foods which can be directly added, without needs for heating or cooling, to thick liquid foods (liquid diets and the like) at room temperature or in a refrigerated state while forming no lumps and by which thickness (viscosity) of foods can be appropriately controlled depending on the addition level the same in using, and to provide a method of producing the same.SOLUTION: The thickener for liquid foods contains xanthan gum and an organic acid and/or an inorganic acid has a higher degree of dissociation than that of lactic acid. The thickener for liquid foods contains salt(s) of the organic acid and/or the inorganic acid. In the thickener for liquid foods, the organic acid is citric acid and the inorganic acid is phosphoric acid. The thickener for liquid foods further contains a hardly digestible dextrin. and thickener for liquid foods for coating and/or for coating and granulating xanthan gum by using an organic acid and/or an inorganic acid having a higher degree of dissociation than lactic acid and methods of producing the same.COPYRIGHT: (C)2013,JPO&INPIT【課題】加熱や冷却の必要がなく、常温や冷蔵状態の濃厚な液状食品(流動食など)に直接添加してもダマにならず、その使用時において適宜、その添加量によってトロミ(粘性)を調整できる、液状食品増粘化剤及びその製造法を提供する。【解決手段】キサンタンガムと、解離度が乳酸よりも大きい有機酸及び/又は無機酸を含有する液状食品増粘化剤。前記有機酸及び/又は無機酸の塩をさらに含有している液状食品増粘化剤。前記有機酸がクエン酸、無機酸がリン酸である液状食品増粘化剤。難消化性デキストリンをさらに含有している液状食品増粘化剤。解離度が乳酸よりも大きい有機酸及び/又は無機酸を用いてキサンタンガムをコーティング及び/又はコーティングすると供に顆粒化する液状食品増粘化剤の製造法。【選択図】図1
