Reaction Steps
Japanese patent application Sho 56/097,248 (Tanaka, 1981) discloses a calcium citrate malate salt of increased solubility. This salt is a 5:2:2 ratio of calcium:citrate:malate, formed by mixing calcium carbonate with citric and malic acids in water at 50° C. to 60° C. and separating the white crystalline material from the mother liquor. When the product is dry (oven drying is used), the temperature is raised to 110° C. -120° C. to sterilize the powder.
