Uses and synthesis of Calcium citrate powder.

Calcium citrate powder is a white powder with the chemical name 2-hydroxypropane-1,2, 3-calcium tricarboxylate - tetrahydrate. Its molecular formula is Ca3(C6H5O7)2·4H2O, soluble in water, but also soluble in strong acids. When heated to 100 ° C, the crystal water is gradually lost, and when heated to 125 ° C, it completely becomes crystal water and becomes anhydrous. The absorption effect of food calcium enhancer is better than that of inorganic calcium. Calcium citrate can be used to strengthen a variety of foods, including infant formula, fruit juices, dairy products, solid drinks, sports drinks, milk, soy milk, health products, and cereal products.

What are the health benefits of calcium citrate?

Effective calcium supplementation and prevention of osteoporosis: The calcium ions in calcium citrate are easily absorbed and utilized by the human body, participating in the formation of bones and the maintenance of bone density, thereby effectively supplementing calcium, preventing and treating osteoporosis, and reducing the risk of fractures.

Promote bone and tooth health: Calcium is the main component of bones and teeth. Adequate calcium intake is essential for the development of bones and teeth in children and adolescents, and is also essential for adults to maintain bone and tooth health. Calcium citrate can provide the calcium needed for growth and development and bone maintenance.

Maintain normal nerve and muscle function: Calcium ions play an important role in nerve signal transmission, muscle contraction and relaxation. Adequate calcium intake helps maintain the normal excitability of the nervous system and the normal function of muscles, and prevents symptoms such as muscle spasms and convulsions.

Promote cardiovascular health: Calcium is involved in the regulation of myocardial contraction and vasodilation. Adequate calcium intake may help maintain normal blood pressure and reduce the risk of cardiovascular disease, but the results of related studies are not completely consistent.

Improve calcium absorption in people with insufficient gastric acid secretion: The absorption of calcium citrate does not require the participation of gastric acid. Even in the case of insufficient gastric acid secretion (such as the elderly, patients with atrophic gastritis, and people who take acid-suppressing drugs for a long time), calcium citrate can be well absorbed. Therefore, calcium citrate is particularly suitable for people with insufficient gastric acid secretion as a calcium supplement.

Good gastrointestinal tolerance: Calcium citrate is less likely to cause gastrointestinal discomfort side effects such as constipation and bloating than calcium carbonate, and is more acceptable to people with sensitive gastrointestinal tract.

High bioavailability: The calcium bioavailability of calcium citrate is high, which is equivalent to or slightly higher than that of calcium carbonate, and is better than other calcium salts such as calcium phosphate.

Application of Calcium citrate powder.

Dietary supplements: This is the main application of calcium citrate. As a supplementary source of calcium, it is used to prevent and treat calcium deficiency and osteoporosis. Calcium is an essential mineral for the human body and is essential for bone health, dental health, nerve function, muscle function, blood coagulation, etc. Calcium citrate has become a common oral calcium supplement ingredient due to its good absorption rate and gastrointestinal tolerance. It is widely used in various calcium preparations, such as tablets, capsules, chewable tablets, granules, oral liquids, etc. It is especially suitable for the elderly with insufficient gastric acid secretion and people who take acid-suppressing drugs for a long time.

Food additives: In the food industry, calcium citrate is approved as a food additive and is used as:

Calcium fortifier: used to increase the calcium content in food, such as fortified juices, beverages, dairy products, cereal products, etc.

Acidity regulator: used to adjust the pH value of food and improve taste and flavor.

Chelating agent: used to prevent metal ions in food from causing oxidative discoloration and extend the shelf life of food.

Anti-caking agent: used to prevent powdered food from caking and maintain product looseness. Calcium citrate is a food additive with high safety and wide application.

Medical use: In the medical field, calcium citrate is used to prepare oral calcium supplements and is sometimes used as:

Calcium-derived drugs: used to treat diseases caused by calcium deficiency such as hypocalcemia and tetany.

Antacids: Calcium citrate has a certain antacid effect, which can neutralize gastric acid and relieve stomach discomfort caused by excessive gastric acid. However, its antacid effect is not as good as calcium carbonate and aluminum hydroxide.

Local hemostatic agent: A complex composed of calcium citrate and gelatin and other ingredients can be used for local hemostasis.

Personal care products: In some personal care products, such as toothpaste and mouthwash, calcium citrate can be used as a source of calcium and may have certain oral health benefits.

Preparation method of Calcium citrate powder

Calcium carbonate method: This is the most commonly used method. React calcium carbonate (such as limestone, shells, etc.) with citric acid aqueous solution. The reaction equation is as follows:

3CaCO₃ + 2C₆H₈O₇ → Ca₃(C₆H₅O₇)₂ + 3H₂O + 3CO₂↑

Calcium carbonate reacts with citric acid to produce calcium citrate, water and carbon dioxide. Carbon dioxide escapes in the form of gas, and the reaction liquid is filtered, washed and dried to obtain the finished calcium citrate.

Calcium hydroxide method: React calcium hydroxide (slaked lime) with citric acid aqueous solution. The reaction equation is as follows:

3Ca(OH)₂ + 2C₆H₈O₇ → Ca₃(C₆H₅O₇)₂ + 6H₂O

Calcium hydroxide reacts with citric acid to produce calcium citrate and water. The reaction solution also needs to be filtered, washed, dried and other steps to obtain the finished calcium citrate product.
