E542Anti-caking agentModerate concern
Bone Phosphate
In plain words
The short version
Hydroxyapatite from defatted bone — a calcium and phosphate source, deprecated in most direct food use.
Why we flag it amber
It's permitted and generally considered safe, but there are a few reasons to be mindful — like sensitivities in some people, debated studies, or intake limits. The Safety section below explains the specifics.
Safety profile
ADI of 40 mg/kg body weight (combined added phosphates, EFSA 2019). The animal-source origin requires BSE-safety controls. Calcium and phosphate are both nutritive at these levels.
