Calcium is necessary for many normal functions of the body, especially bone formation and maintenance. Once the $\ce{CaCO3}$ reacts with the apple juice and raises the pH, the juice is left cloudy in color BUT has the desired pH of 3.4. 4. Probably screwing up other things the the process. I'm using calcium carbonate ($\ce{CaCO3}$) in apple juice to reduce the acidity of the juice. You could pour on a water soluble calcium salt, like calcium chloride, in liquid form, but it would not stay in dissolved form. The solids content of the slurry is high, near to 65 - 70%, various deflocculants are used to maintain a very low viscosity even with the high solids. According to Osteoporosis Australia, the recommended daily intake of calcium, through diet, should be around 1,300 mg per day. You probably know that calcium is important to your bone health. Relevance. Fourteen normal subjects took 1000 mg calcium orally as calcium citrate or calcium carbonate.
