摘要：
PROBLEM TO BE SOLVED: To provide a calcium agent being stable in a solution form even with high concentration, particularly a calcium agent giving bitterness and being stable in a solution form even with high concentration in a wide pH region of weak acidity or higher.SOLUTION: An aqueous calcium solution agent comprises water, calcium, a compound of the formula I and a compound of the formula II as components, where most of the calcium are present as nonionic calcium and constitutes a complex binding to the compound of the formula I and/or the compound of the formula II in the state that their basic skeletons are maintained, at least some of the complex forms colloidal particles, and the aqueous calcium solution agent has a pH of weak acidity or higher and is transparent. [In the formula, Ato Aare each independently Oor OX, and X is a monovalent or polyhydric cation.]【課題】高濃度でも溶液の形態で安定なカルシウム剤、特に、苦味が少なく、且つ弱酸性以上の広いｐＨ領域において高濃度でも溶液の形態で安定なカルシウム剤の提供。【解決手段】水、カルシウム、式Iの化合物、及び式IIの化合物を構成要素として含むカルシウム水溶液剤であって、前記カルシウムは大部分が非イオン性カルシウムとして存在し、且つ式Iの化合物及び/又は式IIの化合物の基本骨格を維持した状態でこれらと結合した複合体を構成し、前記複合体の少なくとも一部分がコロイド粒子を形成しているｐＨが弱酸性以上の透明なカルシウム水溶液剤。［Ａ１～Ａ６は各々独立にＯ－又はＯＸで、Ｘは１価若しくは多価のカチオン］【選択図】なし
