Light Calcium Carbonate, also known as Precipitated Calcium Carbonate, PCC for short, is made by burning limestone and other raw materials into lime and carbon dioxide; then adding water to digest the lime to form lime milk, the main component of which is calcium hydroxide; then introducing carbon dioxide into the lime milk to carbonize it to form calcium carbonate precipitation, and finally dehydrating, drying and crushing it to obtain it.

High Purity
• Purity Level: Light food-grade calcium carbonate typically exceeds 99% purity, making it safe for consumption. It is free from harmful contaminants, heavy metals, and other impurities that are present in industrial-grade calcium carbonate.
• Manufacturing Process: Produced through a controlled chemical process known as precipitation, ensuring that the product is of high purity and quality. The process eliminates impurities that are commonly found in mined calcium carbonate.
Physical Properties
• Appearance: Light food-grade calcium carbonate is a fine, white, odorless powder with excellent brightness and whiteness. This makes it visually appealing for use in food products.
• Particle Size: The particle size is finely controlled during production, typically ranging between 0.1 to 5 microns. Fine particle size improves the material’s texture when added to food or pharmaceuticals.
• Density: Light calcium carbonate has a lower bulk density compared to ground calcium carbonate. This low density is beneficial in applications where lightness and fine texture are needed.
Light food-grade calcium carbonate is widely used in various industries due to its safety, purity, and functionality. Its applications span food, beverages, dietary supplements, and even pharmaceuticals. Here are some of the key applications:
• Calcium Fortification: It is commonly added to a range of food products to increase their calcium content, which is vital for bone health. Products like dairy alternatives (soy milk, almond milk), cereals, and juices often contain calcium carbonate to boost their nutritional value.
• pH Stabilizer: In food processing, light calcium carbonate is used to stabilize pH levels in products like canned vegetables, pickles, and sauces, preventing acidity or spoilage.
• Anti-Caking Agent: In powdered food products, such as flour, sugar, and powdered drink mixes, calcium carbonate is used as an anti-caking agent, preventing clumping and maintaining the free-flowing nature of the product.
• Baking Ingredient: Calcium carbonate is often added to baked goods like bread and pastries. It not only fortifies the product with calcium but also helps improve the texture and crumb structure of the final product.
• Calcium-Enriched Beverages: Many beverages, particularly fortified juices, energy drinks, and mineral waters, use calcium carbonate as a calcium source. It dissolves easily in the product, ensuring the beverage meets the daily calcium requirements without altering the taste or appearance.
• Calcium Supplements: Light food-grade calcium carbonate is widely used in dietary supplements. It is an excellent source of elemental calcium, which is essential for maintaining strong bones, teeth, and overall health. It is often formulated in tablets, capsules, and chewable forms.
• Multivitamins: In addition to calcium supplements, calcium carbonate is included in multivitamin formulations to support overall health and provide a balanced supply of essential nutrients.
