Calcium chloride's freezing-point depression properties are used to slow the freezing of the caramel in caramel-filled chocolate bars also, it is frequently added to sliced apples to maintain texture. During process cheese manufacturing the emulsifying salts are interacting with the calcium in natural cheese therefore the state and amount of calcium and phosphate in natural cheese will have a fundamental effect on the characteristics of the process cheese produced.

Reaction of calcium with air calcium is a silvery white metal the surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Chemical properties: calcium carbonate is insoluble in water and stable at normal temperatures when heated to high temperatures, it decomposes to form calcium oxide with the release of carbon dioxide. Calcium plays a very important role in many bodily functions it helps build stronger, denser bones and keeps bones healthy later in life it also helps with the electricity in nerves, and with muscle contraction in the heart, calcium is the mineral that plays a key role in causing the heart to . The presence of an optimum counter-ion concentration in calcium-induced κ-carrageenan gels at low polymer concentrations of 5 and 10 g/l is observed. Calcium is a metallic element that has the atomic number 20 some of its most important chemical properties are that it has 10 isotopes, an atomic mass of 5008 grams per mole and a melting point of 840 degrees celsius physically, calcium is a solid at room temperature, is slightly softer than .

Calcium intake in the diet (milk, cheese, yogurt) is low vitamin d levels are low and gut calcium absorption is low in many adults, hormonal signals have to take some calcium out of the bones every day to keep blood calcium levels normal. Calcium hydroxide, also known as hydrated or slaked lime, is an inorganic compound with a formula of ca(oh)2 as with other metallic hydroxides, calcium hydroxide has a polymeric structure, and is exactly the same magnesium hydroxide, (mg(oh)2) (also known as brucite). The element calcium (ca) is found in group 2 of the peroidic table, and that makes it an alkaline earth metal it is fairly reactive, and is not found free in nature in compounds, it forms the +2 .

Characteristics and properties under standard conditions calcium is a shiny, silvery metal it is fairly soft and is the lightest of the alkaline earth metals due to its low density. Among all the health benefits of calcium, the most important ones are that it aids in maintaining bone and dental health, as well as helps in the prevention of colon cancer and the reduction of obesity we need it from birth all the way until we reach old age in our infant days, it is required for . The calcium is only absorbed if vitamin d takes part, therefore, a lack of this vitamin would also produce a lack of this mineral in order to avoid this and, especially in certain cases, the ingestion of calcium supplements is recommended with vitamin d.

Whole wheat cracker fortified with tuna bone bio-calcium (bio-ca) powder was developed as health-promoting food rich in calcium fortification with different levels of bi-ca, over the range of 0–50% of whole wheat flour (w/w) on quality and sensory properties of crackers, were determined. Material properties of bone changes with aging how to measure bone density if blood calcium gets too high or too low, the muscles and nerves will not function . A study published in a 2004 issue of obesity showed individuals on a high-calcium, high-dairy diet lost 70 percent more body weight than individuals on a low-calcium diet when caloric intake was the same.
