Calcium in Beverages
Last Updated: February 2007

For most consumers, beverages are the primary source for calcium, such as bottled mineral water, enhanced waters with added calcium, fortified carbonated soft drink, calcium fortified orange juice, cow milk, calcium fortified soy milk, meal replacements and diet supplements. There are many calcium sources to choose from, and this guide provides useful information about each identified source. Many varieties and sources of Calcium salts are commercially available for use in beverage fortification. Beverages and beverage concentrates are exposed to a wide range of temperatures during their manufacture and distribution. Therefore, it is important to know the effect of temperature on the solubility of beverage ingredients. In this manual we provided these type of details for you and your use. In addition to temperatures data, you will find many other great details such as ingredient interactions, solubility versus pH, organoleptic quality, bioavailability, and other scientific information.
