E542 – Bone phosphate
EmulsifierDescription
Tricalcium phosphate derived from animal bones, used as an anticaking agent, emulsifier, and source of calcium
Notes
Bone phosphate, technically known as tricalcium phosphate, is derived from animal bones, typically from cattle or pigs. The bones are processed through cleaning, defatting, and chemical treatment to extract the calcium phosphate compounds that naturally make bones hard and strong. This processing removes organic matter, leaving behind the mineral components. This additive serves dual purposes in food: it works as an anticaking agent to prevent powdering and clumping, and it also acts as a calcium supplement to boost the nutritional content of foods. You'll commonly find it in powdered foods, some dairy products, cereals, and foods that are fortified with calcium for nutritional benefits. Since bone phosphate is derived from animal sources, it's not suitable for vegetarian or vegan diets, and it may not be acceptable under certain religious dietary laws such as halal or kosher, depending on the source and processing methods. Some manufacturers now offer plant-based or synthetic alternatives to meet these dietary requirements, so consumers with these concerns should check product labels carefully.
