  With the recent findings from various astrophysical results hinting towards
possible existence of strange quark matters with the baryonic resonances such
as $\Lambda^0, \Sigma^0, \Xi, \Omega$ in the core of neutron stars, we
investigate the MSW effect, in general, in quark matter. We find that the
resonance condition for the complete conversion of down-quark to strange quark
requires estremely large matter density ($\rho_u \simeq 10^{5}\,\mbox{fm}^{-3}
$). Nonetheless the neutron stars provide a best condition for the conversion
to be statistically significant which is of the same order as is expected from
imposing charge neutrality condition. This has a possibility of resolving the
hyperon puzzle as well as the equation of state for dense baryonic matter.
