Overview
Monocalcium Phosphate (MCP) is a critical feed additive for livestock, poultry, and aquaculture. It is more digestible than other phosphates like dicalcium phosphate (DCP), ensuring better mineral absorption.
Applications
- Animal nutrition — critical feed additive for livestock, poultry, and aquaculture; supports bone and skeletal development, growth rates, and reproductive performance.
- Food industry — fast-acting leavening acid used in baking powders, pancakes, cookies, cakes, and pastry mixes.
- Agriculture — used in fertilizers, particularly as a component of triple superphosphate, providing readily available phosphorus to plants.
- Other uses — pH regulator and stabilizer in processed foods, mineral supplement in cereals and beverages, and used in some dental care products to strengthen enamel.
Key Benefits
- Higher bioavailability than DCP — more digestible, ensuring better mineral absorption.
- Supports bone and skeletal development; improves growth rates and reproductive performance.
- Prevents rickets and improves eggshell quality in poultry layers.
- When mixed with baking soda, releases CO₂ rapidly (60–70% within the first few minutes), causing dough or batter to rise.
