  We study light quark interactions in the instanton liquid at finite
quark/baryon number density analyzing chiral and diquark condensates and
investigate the behaviors of quark dynamical mass and both condensates together
with instanton liquid density as a function of quark chemical potential. We
conclude the quark impact (estimated in the tadpole approximation) on the
instanton liquid could shift color superconducting phase transition to higher
values of the chemical potential bringing critical quark matter density to the
values essentially higher than conventional nuclear one.
