Abstract: In associative and alternative algebras a minimal ideal is either trivial or simple. This is not known for quadratic Jordan algebras. In the present note we show that a minimal ideal is either trivial or $ \mathcal{D}$-simple (possesses no proper ideals invariant under all inner derivations induced from the ambient algebra). In particular, the heart of any quadratic Jordan algebra is either trivial or $ \mathcal{D}$-simple. Hearts have recently played an important role in Zelmanov's theory of prime Jordan algebras.
