E542 Bone phosphate

What is Bone phosphate (E542)?

Bone phosphate (E542) is derived from animal bones and is used as a stabilizer or anti-caking agent in powdered food products, such as powdered milk or icing sugar. It helps to prevent the clumping of powdered substances and ensures they remain free-flowing. E542 is primarily composed of calcium phosphate, a natural component of animal bones.


Why do I have an intolerance?

Individuals with an intolerance to bone phosphate may experience adverse reactions due to sensitivities to animal-derived ingredients. In some cases, those with digestive or metabolic issues may struggle to process calcium phosphate effectively, leading to symptoms like nausea or stomach discomfort. Furthermore, if you follow a vegetarian or vegan diet, this additive may not align with your lifestyle preferences, contributing to avoidance.


What can I do about it?

To manage intolerance to E542, avoid products that list bone phosphate on the label, particularly in powdered or processed foods. Plant-based alternatives are widely available and may provide a suitable replacement in your diet. Checking product labels for anti-caking agents of non-animal origin is a helpful way to avoid exposure.
