This product stands out for its ultra-high purity with strict limits on heavy metals and microbial contaminants, ensuring full compliance with global food safety regulations. Its uniform 3-5μm particle size enables consistent dispersion in food matrices, preventing aggregation and maintaining product uniformity. With a neutral to slightly alkaline pH value, it will not alter the natural flavor of food products, and its high whiteness enhances the visual appeal of baked goods, dairy products, and confectionery. It solves the common pain points of traditional calcium additives, such as inconsistent particle size, high impurity levels, and negative impacts on food taste.
The food-grade precipitated calcium carbonate has an average particle size of 3-5μm, with a minimum purity of 99.5%. The moisture content is controlled at ≤0.2%, and the pH value of a 10% aqueous suspension ranges from 8.0 to 9.0. Lead and arsenic contents are limited to ≤10ppm and ≤2ppm respectively, meeting the most stringent food safety standards. The loss on ignition is between 42.0% and 44.0%, and it is completely insoluble in water and common organic solvents. The product has a whiteness of ≥92%, providing excellent whitening performance for food products. It is packaged in food-grade PE bags, with each bag containing 25 Kilograms of product, and each batch undergoes third-party testing to ensure compliance with FDA regulations.
This product is widely used in the food and beverage industry as a calcium fortifier for dairy products, fruit juices, and baked goods, helping to increase the calcium content of daily diets. It is also used as a texture modifier in flour to improve the elasticity and plasticity of dough, enhancing the quality of pasta and bread. In pet food, it serves as a nutritional supplement to support bone and teeth health for companion animals. Additionally, it can be used as a whitening agent in confectionery and chewing gum, improving the visual appeal and shelf life of finished products. It is compatible with most food additive formulations and does not react with other ingredients under normal processing conditions.
