    • The present invention comprises a composition of matter consisting essentially of citric acid and one or more calcium compounds selected from the group consisting of calcium hydroxide, calcium carbonate and calcium oxide. The composition of matter is preferably a substantially dry mixture which may be used, for example, as a powder for making an "instant" beverage of potable liquid. A preferred calcium compound/citric acid molar ratio in the composition of matter of the present invention is between about 0.6 and about 1.5.In a most preferred embodiment, the composition of matter of the present invention consists essentially of calcium hydroxide and citric acid having a calcium compound/citric acid or calcium hydroxide/citric acid molar ratio of about 1.25.The composition of matter of the present invention has a utility demostrated by dissolution in water to form a liquid dietary calcium supplement comprising soluble calcium citrate. This composition of matter may comprise one or more of a flavorant, lubricant, sweetener or colorant usable to maintain a powdery texture or to enhance the flavor of a beverage prepared therefrom.
    • 本发明包括基本上由柠檬酸和一种或多种选自氢氧化钙,碳酸钙和氧化钙的钙化合物组成的物质组合物。 物质的组成优选为基本上干燥的混合物,其可以用作例如用于制造饮用液体的“即时”饮料的粉末。 本发明物质组合物中优选的钙化合物/柠檬酸摩尔比为约0.6至约1.5。 在最优选的实施方案中,本发明的物质组成基本上由具有约1.25的钙化合物/柠檬酸或氢氧化钙/柠檬酸摩尔比的氢氧化钙和柠檬酸组成。 本发明的物质组成具有通过在水中溶解形成含有可溶性柠檬酸钙的液体膳食钙补充剂的功效。 该物质组合物可以包含一种或多种调味剂,润滑剂,甜味剂或着色剂,其可用于保持粉末质地或增强由其制备的饮料的风味。
