In the soliton model for baryons the Gottfried sum S(G) is to lowest order in the quark masses given by one third of the ratio between the non-electromagnetic part of the neutron-proton mass split and the difference between the d and u current quark masses S(G) = (M(n)-M(p))strong/3(m(d)-m(u)). It is shown that this result is independent of the form of the effective action and that higher order corrections are very small.
