It is demonstrated how in the soliton approach to baryons a small but non-vanishing matrix element of the axial singlet current is obtained. Furthermore it is shown that these models also provide a mechanism to disentangle the ``matter" and ``glue" contributions to this matrix element. Numerical results indeed exhibit a cancellation between these two components. However, the magnitudes of both turn out to be significantly smaller than unity.
