Calcium citrate (CAS:5785-44-4) and calcium carbonate (CAS:471-34-1) are both important sources of calcium, but they differ in application fields and properties. Calcium citrate is primarily used in food and health products, known for its high bioavailability and ease of absorption. In contrast, calcium carbonate is widely used in industrial and construction fields, known for its low cost and wide range of applications.
Molecular Formula: C₁₂H₁₀Ca₃O₁₄
Calcium citrate (CAS:5785 44 4) is a common calcium supplement extensively used in the food, beverage, and health product industries. It has high bioavailability, easy absorption by the human body, and causes less gastrointestinal irritation. Calcium citrate is often used in the following fields:
Food and Beverage: As a food additive china made in Forward Science factory, calcium citrate is added to juices, dairy products, and cereals to increase calcium content.
Health Products: Due to its high absorption rate, calcium citrate is a preferred ingredient in many calcium supplements, especially suitable for the elderly and those needing extra calcium.
Pharmaceuticals: In some medicinal formulations, calcium citrate is used as a calcium source to prevent and treat calcium deficiency.
The production process of calcium citrate
Raw Material Preparation: The main raw materials are citric acid and calcium hydroxide.
Reaction Process: Dissolve citric acid in water, then gradually add calcium hydroxide, controlling the reaction temperature and pH to generate calcium citrate precipitate.
Filtration and Washing: Filter out the generated calcium citrate precipitate and wash with water to remove impurities.
Drying and Crushing: Dry the washed calcium citrate and then crush it to the desired particle size.
Precautions
Storage Conditions: Calcium citrate (cas 5785 44 4) should bestored in a dry, cool environment to avoid moisture and high temperatures.
Usage Precautions: When used in food and health products, the dosage should be strictly controlled to comply with relevant regulations and standards.
Safety Protection: During operation, wear protective gloves and masks to avoid inhalation of dust.
Molecular Formula: CaCO₃
The calcium carbonate is a versatile compound widely used in industrial, construction, agricultural, and food fields. Its main uses include:
Building Materials: Calcium carbonate is a key component of cement, lime, and concrete, extensively used in construction and road building.
Industrial Fillers: In plastics, rubber, and coatings, calcium carbonate as a filler can enhance the strength and durability of products.
Agriculture: Calcium carbonate is used as a soil amendment to neutralize acidic soils and improve soil pH.
Food Additives: In the food industry, calcium carbonate is used as an anti-caking agent, acidity regulator, and calcium fortifier.
The production process of calcium carbonate
There are two main methods for producing calcium carbonate: natural ore method and chemical synthesis method.
Natural Ore Method
Mining and Crushing: Limestone or marble is mined from quarries and then crushed and screened.
Grinding and Classification: The crushed limestone is ground to obtain different particle sizes of calcium carbonate powder.
Surface Treatment: Depending on the application needs, calcium carbonate is surface-treated to improve dispersibility and compatibility.
Chemical Synthesis Method
Raw Material Preparation: The main raw materials are lime (CaO) and carbon dioxide (CO₂).
Reaction Process: Dissolve lime in water to produce calcium hydroxide solution, then introduce carbon dioxide to generate calcium carbonate precipitate.
Filtration and Drying: The generated calcium carbonate precipitate is filtered out and dried.
