Product Characteristics
Nutritional balance: Rich in phosphorus and calcium, DCP supports normal bone development, tooth growth, and metabolic functions in animals, while maintaining and balancing nutrient absorption and utilization.
Excellent water solubility: DCP is readily soluble in acidic substances. It has high solubility in the animal gastrointestinal environment and can be fully absorbed, thus offering extremely high bioavailability.
High purity: Produced using modern processes, DCP has a mild odor and very low levels of heavy metals (such as arsenic and lead), ensuring feed safety.
High stability: Dicalcium phosphate is chemically stable and has good compatibility with other feed ingredients.
DCP (dicalcium phosphate) is an odorless, tasteless, and highly bioavailable calcium and phosphorus supplement. Due to its purity and variety of forms, DCP is widely used in aquaculture, laying hen farming, pet food, pharmaceuticals, agriculture, and other industries, making it an important functional additive.
Agriculture and Feed
High-efficiency phosphate fertilizer: As a high-quality phosphate fertilizer raw material, dicalcium phosphate is suitable for acidic and neutral soils. It continuously supplies essential calcium and phosphorus elements to crops, effectively enhancing soil fertility and crop yield.
Feed additive: DCP is one of the most important sources of calcium and phosphorus in animal feed. For example, in laying hen farming, adding DCP to feed serves as a safe and reliable nutritional supplement, significantly promoting bone development and egg quality, while also improving feed conversion rates and reducing farming costs.
Food Processing
Leavening agent: Food-grade dicalcium phosphate is widely used in baked goods such as bread, cookies, and cakes. It promotes the formation of a uniform, dense, and porous structure inside the dough, improving product texture.
Nutritional supplement: As an efficient source of calcium and phosphorus, DCP is often added to cereals, milk powder, and beverages to quickly supplement key minerals and maintain bone and metabolic health.
Anti-caking agent: In powdered foods (such as seasoning powders and protein powders), dicalcium phosphate acts as an anti-caking agent, preventing particle clumping and maintaining product stability.
Bone matrix source: As a manufacturer of dicalcium phosphate, Hengxin uses natural bones such as cattle and pig bones as raw materials, with heavy metal content far below international standards. The product has a calcium-to-phosphorus ratio of 1.37:1, which promotes animal absorption and utilization, significantly improving feed conversion efficiency.
Naturally low fluorine: Animal bones naturally act as a barrier against fluorine accumulation during growth. As a result, bone-derived dicalcium phosphate has extremely low fluorine content, making it safer for aquaculture, laying hens, and pets.
Strict quality standards: Hengxin has obtained China's Single Feed Production License. Its DCP features high purity, with measured calcium content of 25.4% and total phosphorus content of 18.5%. The company strictly controls bone source quality with full traceability, providing customers with reliable and safe feed formulations.
Modern production equipment: Hengxin uses a fully automated production line, with the entire process from raw materials, production, and finished products to packaging monitored by a central control room. This effectively prevents cross-contamination and ensures product stability.
Stable and reliable: Supported by a consistent supply of high-quality raw materials and large-scale production, the annual output of dicalcium phosphate reaches 35,000 tons. The intelligent warehousing area covers 22,266 m², ensuring long-term, stable, and rapid product delivery.
Professional service: The team provides full-process technical support, from raw material selection to product application, helping customers grow their businesses and serving as a trustworthy partner.
Yes, dicalcium phosphate is a recognized safe inorganic compound. Also known as calcium hydrogen phosphate or DCP, it can be classified into food grade and feed grade based on its intended use, and is widely used in food, pharmaceuticals, and animal feed.
Food and supplements: Added to bread, cakes, cereals, and cookies to improve texture and provide calcium and phosphorus.
Pharmaceuticals: Used as a safe filler and flow agent in tablets and capsules.
Animal feed: There are two main sources: one is bone matrix, and the other is mineral matrix. Rich in phosphorus and calcium, it promotes bone development, eggshell quality, milk production, and overall growth in animals.
Hengxin offers bone-derived dicalcium phosphate with a calcium content of 25.4% and total phosphorus content of 18.5%. Relevant certificates are provided upon request.
Feed-grade dicalcium phosphate is a safe and efficient source of calcium and phosphorus supplementation in deer rations. It plays a key role in deer skeletal development, doe lactation performance, fetal development, and antler growth.
Special note: Priority should be given to feed-grade dicalcium phosphate with low fluoride content. Avoid using fertilizer-grade dicalcium phosphate, as it may contain unwanted chemical impurities or heavy metals.
To find a suitable dicalcium phosphate manufacturer, you can use tools such as social media, search engines (e.g., Google), and AI-assisted search for initial screening. On this basis, comprehensively evaluate the manufacturer's capabilities based on key indicators such as certifications, production scale, supply capacity, and delivery lead times to ensure they can meet your specific needs.
Hengxin is a professional manufacturer of bone-derived dicalcium phosphate (DCP) and has obtained multiple international certifications, including ISO 9001, HALAL, GMP, and BRC. With an annual production capacity of 35,000 metric tons of DCP, Hengxin ensures product supply stability and long-term delivery reliability.
