Monocalcium phosphate Anhydrous, often abbreviated as MCP-A, is a chemical compound with the formula Ca(H2PO4)2. It is a white, odorless, and tasteless powder, and its properties make it versatile for different applications. In the food industry, it is used as a leavening agent in baking, while in animal nutrition, it serves as a vital dietary supplement for calcium and phosphorus. Additionally, MCP-A is used in fertilizers to provide essential nutrients for plant growth. Its CAS number is 7558-23-8.
Monocalcium Phosphate Anhydrous (MCP-A) has various applications across different industries due to its chemical properties. Here are some of its most common uses:
1. Food Industry:
Leavening Agent: MCP-A is widely employed as a leavening agent in baked goods. It releases carbon dioxide gas when mixed with an acid (e.g., sodium aluminum sulfate) and water, contributing to the rising and expansion of dough or batter. This is crucial for the development of baked products like bread, cakes, muffins, and pancakes.
Baking Powder: MCP-A is a key component of double-acting baking powder, which provides both fast and slow leavening actions. This results in consistent and controlled dough or batter expansion during baking.
Self-Rising Flours: It is used in the production of self-rising flours, eliminating the need for additional leavening agents.
2. Animal Feed:
Nutritional Supplement: In animal nutrition, MCP-A serves as a critical nutritional supplement for both phosphorus and calcium. It is included in animal feed formulations to ensure proper growth, bone development, and overall health in poultry, livestock, and other animals.
Phosphorus Source: MCP-A provides a highly bioavailable source of phosphorus, particularly in monogastric animals like poultry and swine.
3. Fertilizer:
Phosphorus Fertilizer: MCP-A is used as a source of phosphorus and calcium in fertilizers. It provides essential nutrients to plants, promoting healthy root development, flowering, fruiting, and overall plant growth.
Water-Soluble Fertilizers: It can be incorporated into water-soluble fertilizers, which are readily absorbed by plants. This helps address nutrient deficiencies and improve crop yields.
4. Pharmaceuticals:
In some pharmaceutical formulations, MCP-A is used as a calcium and phosphorus supplement, particularly for individuals with dietary deficiencies.
5. Water Treatment:
MCP-A can be used in water treatment processes to reduce corrosion in water distribution systems by forming a protective phosphate layer inside pipes.
6. Industrial Applications:
It may find applications in various industrial processes where a source of calcium and phosphorus is needed.
MCP-A is appreciated for its ability to deliver critical nutrients in a highly bioavailable form, ensuring optimal growth and performance in food products, animal nutrition, and crop cultivation. It plays a pivotal role in various processes, from enhancing the texture and structure of baked goods to supporting the well-being of animals and the productivity of agricultural crops.
