High-Quality Ground Calcium Carbonate (Food Additives) from China Suppliers and Factory - 25kg/500kg Packaging
Product Description
Improving milk's nutritional value, extends shelf life, and ensures uniform mixing to maintain stable quality.
Our food-grade calcium carbonate effectively enhances the nutritional value of milk. It acts as an acidity regulator, helping to stabilize the pH of milk, preventing acidification, and extending its shelf life. Food-grade heavy calcium carbonate also helps to evenly mix other ingredients, ensuring stable milk quality and preventing sedimentation or separation.
Enhancing texture and appearance in foods, provides additional calcium for bone health.
Our food-grade calcium carbonate is commonly used to adjust the texture and consistency of food, and to improve product stability. Food grade ground calcium carbonate helps improve the appearance of food, making it more uniform and smooth, especially in candies, biscuits, and powdered snacks, providing a finer texture. Secondly, our food-grade calcium carbonate, as a source of calcium, provides consumers with additional nutritional support, helping to supplement calcium and promote bone health. It can also act as an acidity regulator, balancing the pH of snacks and extending product shelf life.

Frequently Asked Questions
What is food-grade calcium carbonate and how is it used in the food industry?
Food-grade calcium carbonate is a highly purified form of calcium carbonate (CaCO₃) that meets strict safety and quality standards for use in food products. It is widely used as an acidity regulator, anti-caking agent, calcium supplement, and texture improver in products such as dairy, snacks, biscuits, candies, and powdered beverages.
How does food-grade calcium carbonate extend the shelf life of milk?
Food-grade calcium carbonate acts as an acidity regulator that helps stabilize the pH level of milk, preventing unwanted acidification. By maintaining a balanced pH environment, it inhibits the growth of acid-producing bacteria, thereby extending the shelf life and preserving the freshness and quality of the milk.
What are the key quality specifications of your food-grade calcium carbonate?
Our food-grade calcium carbonate contains a minimum of 97% CaCO₃ with a maximum MgO content of 0.5%, an average particle size of no more than 45 nm, a whiteness of at least 95%, a pH value between 8 and 10, and a water content not exceeding 0.4%. The activator used is fatty acid, ensuring excellent dispersion and compatibility in food applications.
Can your food-grade calcium carbonate be customized for specific applications?
Yes. We offer comprehensive OEM services that allow customers to customize product specifications, particle size, packaging, and other parameters to suit their specific food production requirements. Our professional R&D team works closely with clients to optimize formulations and ensure the best performance in their target applications.
Is your food-grade calcium carbonate environmentally friendly?
Absolutely. Our company operates an independent green mine raw material production base, ensuring that our calcium carbonate is sourced and processed in an environmentally responsible manner. We have established an integrated industrial chain that combines eco-friendly raw material extraction with advanced nano material deep processing technologies.
What after-sales support do you provide to your customers?
