Abstract
The estimations of the light quark mass differences, $m_d-m_u$, and the light quark condensate differences, $<\bar DD> - <\bar UU>$, are obtained in the framework of the \qm\ with QCD vacuum induced \q\ \ia . We consider long - wave condensate and short - wave \s\ contributions to the electromagnetic \hn\ mass \di s and show that the latter significantly improve the results on baryon octet. The results are: $m_d-m_u \approx 3.5\ MeV$ and $<\bar DD> - <\bar UU> \approx -(0\sim 3)\cdot10^{-3}<\bar UU>$.
