Monocalcium phosphate

Monocalcium phosphate (CAS 7758-23-8), also known as MCP and classified as E341i, is a calcium phosphate salt used primarily as a leavening acid and pH regulator in food manufacturing. Its fast acid-release profile makes it a preferred choice in baking systems where rapid CO₂ generation is required. In baked goods, it acts as a fast-acting leavening acid, reacting with sodium bicarbonate to produce lift.

This chemical is essential for products such as self-rising flour, baking powder blends, and pancake mixes. Feed manufacturers incorporate it as a bioavailable phosphorus and calcium supplement in poultry and swine diets. It is also used in aquaculture diets to support bone development and feed conversion. Food processors use it as a buffering and sequestering agent in processed cheeses and canned products to stabilize pH levels.

In fertilizer applications, it functions as a soluble phosphate source that improves nutrient uptake in high-value crop programs. This versatility makes it a staple in both the agricultural and food processing sectors. The product is supplied as a white powder or granule, with granulated forms preferred in feed and fertilizer blending for improved flowability. Standard grades include food-grade (FCC compliant) for baking.

Other available options include feed-grade for animal nutrition use. These quality standards ensure the material meets the rigorous safety and performance requirements of global industrial and food manufacturing supply chains.
