Food grade Calcium phosphate dibasic CAS 7757-93-9

What is Calcium Phosphate Dibasic?

Calcium phosphate dibasic is an inorganic salt composed of calcium ions and hydrogen phosphate ions.

Its common chemical formula is:

CaHPO4

It may also exist in hydrate form, such as calcium hydrogen phosphate dihydrate:

CaHPO4⁻ ⇌ 2H₂O

In the food, pharmaceutical, and feed industries, calcium phosphate dibasic is often referred to as Dicalcium phosphate or DCP . It belongs to the calcium phosphate family, and is part of the same calcium phosphate series as calcium dihydrogen phosphate and tricalcium phosphate, but its functions and applications differ.

Common names include:

· Calcium phosphate dibasic;

· Dicalcium phosphate;

· Dibasic calcium phosphate;

· Calcium hydrogen phosphate;

· Calcium hydrogen phosphate;

· Dibasic calcium phosphate;

· Calcium monohydrogen phosphate;

· DCP.

Food-grade Calcium phosphate dibasic is usually a white or off-white powder with no obvious odor. It has low solubility in water, but its solubility increases in acidic environments.

Food-grade calcium phosphate dibasic typically has the following characteristics:

· White or off-white powder ;

· It can provide calcium and phosphorus ;

· Low water solubility ;

· It dissolves more readily in acidic systems ;

· It exhibits good powder stability ;

· It can be used for nutritional fortification and mineral supplementation ;

· It can be used as a functional excipient in tablet and powdered foods ;

· It can improve powder flowability and reduce agglomeration ;

· Food-grade products have strict controls on indicators such as heavy metals, arsenic, lead, and fluorides .

What are the main uses of food-grade Calcium Phosphate Dibasic?

1. Calcium source

Calcium phosphate dibasic contains calcium and can be used as a source of calcium in food.

The significance of calcium in food nutrition

Calcium is an essential mineral for the human body and mainly participates in:

· Bone and teeth formation;

· Muscle contraction;

· Nerve conduction;

· Blood clotting;

· Multiple enzyme reactions;

· To maintain normal physiological functions.

Food companies can increase the calcium content of their products by adding food-grade calcium phosphate dibasic, which can then be used in calcium-fortified foods or nutritional supplements.

2. Phosphorus source

Calcium phosphate dibasic also contains phosphorus. Phosphorus is one of the essential minerals for the human body and participates in:

· Skeletal and dental structure;

· Energy metabolism;

· ATP formation;

· Cell membrane structure;

· Acid-base balance;

· Nucleic acid composition.

Therefore, it can be used in formulations that require simultaneous supplementation of calcium and phosphorus.

3. Nutritional fortifiers

Food-grade calcium phosphate dibasic can be used as a nutritional fortifier in a variety of foods.

Possible applications:

· milk powder;

· Nutritional powder;

· Meal replacement powder;

· Protein powder;

· Cereal foods;

· Sports nutrition products;

· Children's nutritional foods;

· Nutritional foods for middle-aged and elderly people;

· Dietary supplements.

Main function:

· Provides calcium;

· Provides phosphorus;

· Adjust the calcium-to-phosphorus ratio;

· Supports mineral fortification;

· Improve nutrition labeling;

· Combined with nutrients such as vitamin D, magnesium, and zinc.

4. Tablet excipients and fillers

Calcium phosphate dibasic is widely used in tablet foods and nutritional supplements as a filler, tableting excipient, or mineral carrier.

Main function:

· Increase tablet volume;

· Improve powder flowability;

· Improve tableting process;

· Increase tablet hardness;

· Reduce the risk of sticking and impact;

· Improve tablet stability;

· As a source of minerals.

Common products:

· Calcium tablets;

· Compressed candy;

· Chewable tablets;

· Vitamin and mineral tablets;

· Compound nutritional tablets;

· Sports nutrition tablets.

This is also one of the most important applications of Calcium Phosphate Dibasic in the food and nutritional supplement industry.

5. Anti-caking agent

Calcium phosphate dibasic can be used as an anti-caking or flow-improving ingredient in powdered foods.

Main function:

· Reduce moisture absorption and clumping;

· Improve powder flowability;

· Improve mixing uniformity;

· Improve metering and filling efficiency;

· Easy to mix and disperse;

· Improve the shelf-life stability of powder products.

Possible applications:

· Solid beverages;

· Seasoning powder;

· spice powder;

· Milk tea powder;

· Coffee creamer;

· Protein powder;

· Nutritional powder;

· Composite powder formulation.

6. Powdered food flow improvers

In the production of powdered foods, flowability directly affects the mixing, conveying, metering, packaging, and preparation experience.

Calcium phosphate dibasic may help improve:

· Powder looseness;

· Liquidity;

· Dispersion;

· Filling stability;

· Premix uniformity;

· Convenience of using powder.

It can be used in combination with powder additives such as silica, tricalcium phosphate, and magnesium carbonate.

7. Baking and leavening system auxiliary ingredients

In baking systems, calcium phosphate dibasic can be used as one of the compound phosphate components to regulate system performance.

Possible functions include:

· Regulate acid-base balance;

· Improve powder flowability;

· Participating in mineral fortification;

· Improve the stability of premixed powder;

· It can be compounded with other leavening agent components.

However, if the goal is an acidic leavening agent that rapidly produces carbon dioxide, monocalcium phosphate is usually more commonly used.

8. Processing aids and stabilizing ingredients

In some food formulations, calcium phosphate dibasic can be used as a processing aid.

Possible uses:

· Improve powder processing;

· As a mineral carrier;

· Improve mixing uniformity;

· Stable nutrient premix;

· Adjusting the mineral system;

· Improve the structure of tablet or powder products.

Summarize

Calcium phosphate dibasic , also known as Dicalcium phosphate or DCP , is an important calcium phosphate salt with the following common chemical formula:

CaHPO4

It can also exist as a dihydrate:

CaHPO4⋅2H2O CaHPO 4 ⋅2H 2 O

It belongs to the Calcium phosphate family, but is different from calcium dihydrogen phosphate and tricalcium phosphate.

In our daily lives, we may come into contact with food-grade calcium phosphate dibasic through the following products:

· Milk powder and nutritional powder;

· Solid beverages and instant beverage powders;

· Compressed candies and chewable tablets;

· Baking premixes and baking powders;

· Seasoning powders and powdered ingredients;

· Dietary supplements;

· The ingredients list includes dicalcium phosphate or calcium phosphate.

The main uses of food-grade calcium phosphate dibasic include:

· Calcium source;

· Phosphorus source;

· Nutritional fortifiers;

· Tablet excipients and fillers;

· Anti-caking agents;

· Powdered food flow improvers;

· Auxiliary ingredients in baking and leavening systems;

· Processing aids and stabilizing ingredients.

Finally, it must be emphasized that food-grade calcium phosphate dibasic acid must be used within the limits stipulated by food regulations and standards; industrial-grade products cannot be used in food processing or for human consumption. For food companies, selecting compliant food-grade raw materials, clearly identifying anhydrous or hydrated forms, accurately calculating calcium and phosphorus content, paying attention to solubility and taste, and conducting application testing and ensuring label compliance are key to the safe and effective use of calcium phosphate dibasic acid.
