  The three flavor soliton approach for baryons is utilized to discuss effects
of flavor symmetry breaking in the baryon wave--functions on axial current
matrix elements. The flavor content of the singlet axial current matrix
elements, that parameterizes the quark spin contribution to the total angular
momentum, is disentangled and studied as a function of the effective flavor
symmetry breaking. Here the nucleon and the Lambda--hyperon are considered.
