Dicalcium phosphate, a calcium phosphate compound, holds a significant place in various industries and fields due to its wide range of applications. Whether in food production, pharmaceuticals, or animal nutrition, dicalcium phosphate plays a vital role in providing essential nutrients and contributing to the overall well-being of living organisms. In this blog, we will explore the properties, uses, and benefits of dicalcium phosphate, shedding light on its importance in different sectors.

1. Understanding Dicalcium Phosphate:

Dicalcium phosphate, with the chemical formula CaHPO₄, is a white, odorless powder consisting of calcium and phosphate ions. It is formed through the reaction of calcium sources, such as calcium carbonate or calcium hydroxide, with phosphoric acid. The resulting compound contains approximately 24% calcium and 18% phosphorus.

2. Food and Beverage Industry:

a. Nutritional Supplement:

Dicalcium phosphate is widely used as a nutritional supplement in food and beverage products. It serves as a source of calcium and phosphorus, which are essential minerals for maintaining strong bones and teeth. It is commonly added to dairy products, baked goods, breakfast cereals, and nutritional drinks to enhance their nutrient content.

b. Leavening Agent:

In baking, dicalcium phosphate acts as a leavening agent, aiding in the rise and texture of baked goods. It reacts with baking soda to produce carbon dioxide, creating a light and fluffy texture in cakes, cookies, and other baked treats.

3. Pharmaceutical and Health Industry:

a. Calcium and Phosphorus Supplement:

Dicalcium phosphate is used in the formulation of calcium and phosphorus supplements, often combined with other vitamins and minerals. These supplements help support bone health, prevent osteoporosis, and maintain proper mineral balance in the body.

b. Tablet Filler and Binder:

Due to its compressibility and flow properties, dicalcium phosphate is frequently used as a filler and binder in tablet manufacturing. It provides structural integrity and aids in the formation of tablets, ensuring consistent dosage and ease of swallowing.

4. Animal Nutrition:

Dicalcium phosphate is an essential ingredient in animal feed and plays a vital role in ensuring proper growth, development, and overall health in livestock and poultry. It provides a balanced supply of calcium and phosphorus, promoting bone strength and eggshell quality in laying hens. Additionally, dicalcium phosphate serves as a valuable source of phosphorus for ruminant animals, contributing to their metabolic processes and productivity.

5. Safety Considerations:

Dicalcium phosphate is generally regarded as safe for consumption and use in the recommended doses. However, it is important to follow guidelines and regulatory standards specific to each industry and application. Excessive intake or improper usage may lead to imbalances in calcium and phosphorus levels, potentially impacting health.


Dicalcium phosphate, with its versatile properties and multiple applications, plays a significant role in diverse industries. From its role as a nutritional supplement in food products to its use in pharmaceuticals and animal nutrition, dicalcium phosphate contributes to the well-being of humans and animals alike. As a source of essential minerals, it helps support bone health, ensures proper nutrient balance, and aids in various industrial processes. With ongoing research and advancements, the applications and benefits of dicalcium phosphate are likely to expand, further emphasizing its importance in different sectors.
