E543 – Calcium sodium polyphosphate
EmulsifierDescription
Complex salt formed by polymerizing phosphoric acid with calcium and sodium
Notes
Calcium sodium polyphosphate is a complex salt made from phosphoric acid that has been polymerized, which means multiple phosphoric acid molecules have been chemically linked together into longer chains. It's then combined with both calcium and sodium to create this versatile food additive. The process involves heating phosphoric acid (which can be derived from phosphate rock) at high temperatures and then treating it with calcium and sodium compounds. This additive works as an emulsifier, helping ingredients that normally don't mix well (like oil and water) to stay combined and create smooth, stable textures. You'll commonly find it in processed meats like sausages and deli meats, where it helps bind water and fat together, as well as in some dairy products and baked goods. It also acts as a stabilizer, helping maintain the texture and appearance of foods during storage. This is a synthetic compound created through industrial processes, though it's made from naturally-occurring phosphate minerals. It's suitable for vegetarian and vegan diets as it contains no animal-derived ingredients, and it doesn't present concerns for most religious dietary laws. The phosphates are the same type of compounds naturally found in many foods, and this additive is considered safe for consumption within regulated limits by food safety authorities worldwide.
