Technical Document

Brief Overview 

Calcium phosphate is a group of compounds containing calcium ions and phosphate ions. Calcium phosphate food grade is a type of calcium phosphate that is suitable for use in food and beverage products. It is typically derived from natural sources, such as animal bones or rock minerals, and is processed to remove impurities and ensure safety and quality. Calcium phosphate is commonly used as a nutritional supplement in foods and beverages, providing a source of calcium and phosphate that can be easily absorbed by the body. It is often added to dairy products, baked goods, and other processed foods to fortify them with these essential minerals.

Manufacturing Process

The raw materials for calcium phosphate are typically derived from natural sources such as rock minerals or animal bones. These sources must be carefully selected to ensure purity and safety. The raw materials are cleaned and processed to remove impurities and ensure quality. The processed raw materials are treated with an acid, typically hydrochloric acid, to dissolve the calcium phosphate and release it from the other components. The resulting solution is then filtered to remove any remaining impurities.The dissolved calcium phosphate is then mixed with a solution of ammonia or other alkaline substance, which causes the calcium phosphate to precipitate out of the solution in the form of a fine powder.The precipitated calcium phosphate is washed and purified to remove any remaining impurities, then dried to remove excess moisture.

Food Industry 

Calcium phosphate is often added to food and beverage products as a source of calcium and phosphate, which are essential minerals for strong bones and teeth. It can be found in dairy products, breakfast cereals, and other fortified foods.Calcium phosphate can act as a leavening agent in baked goods such as bread, cakes, and pastries. It reacts with other ingredients in the dough or batter to release carbon dioxide gas, which helps the product rise and become light and fluffy. It can help stabilize and thicken certain food products, such as sauces, dressings, and spreads. It can improve texture, prevent separation, and extend shelf life.Calcium phosphate can be used as an anti-caking agent in powdered or granulated food products, such as spices, seasoning blends, and instant drinks. It helps to prevent clumping and ensures that the product flows smoothly. It is also used to adjust the pH of food products, such as cheese and processed meats, to improve texture, flavor, and safety.

Pharmaceutical Industry

Calcium phosphate is often used as a tablet binder, which helps to hold the active ingredients together and form a solid tablet. It can improve the strength and durability of tablets, and ensure that they dissolve properly in the body. Calcium phosphate is a common excipient in pharmaceutical formulations, which means it is an inactive ingredient used to improve the physical characteristics of the drug. It can improve flowability, compressibility, and lubrication of the drug formulation. Calcium phosphate can be used as a filler in capsules, tablets, and other dosage forms. It can increase the bulk of the formulation and improve the appearance and consistency of the final product. Calcium phosphate can be used as a nutrient supplement in certain pharmaceutical products, such as vitamins and mineral supplements. It can provide a source of calcium and phosphate, which are essential minerals for bone health. Calcium phosphate is often used in dental applications, such as toothpaste and dental filling materials. It can help to strengthen tooth enamel, remineralize damaged teeth, and improve oral health.

Other Applications 

Calcium phosphate is commonly used as a fertilizer, providing essential nutrients to plants such as calcium and phosphate. It can improve soil fertility and enhance plant growth and yield. Calcium phosphate is often added to animal feed as a mineral supplement. It can provide a source of calcium and phosphorus, which are essential minerals for animal growth and health. Calcium phosphate can be used as a soil conditioner, improving soil structure and fertility. It can also help to neutralize acidic soils, which can inhibit plant growth. Calcium phosphate can be used in water treatment to remove impurities and improve water quality. It can help to reduce levels of heavy metals, such as lead and copper, and improve the clarity and taste of the water. Calcium phosphate can be used in bioremediation, a process that uses microorganisms to break down and detoxify environmental pollutants. It can help to enhance the activity of microorganisms and promote the degradation of pollutants.
