We investigate the effect of a six fermion determinant interaction on color superconductivity as well as on chiral symmetry breaking. Coupled mass gap equations and the superconducting gap equation are derived through the minimization of the thermodynamic potential. The effect of nonzero quark-antiquark condensates on the superconducting gap is derived. This becomes particularly relevant for the case of 2-flavor superconducting matter with unpaired strange quarks in the diquark channel. While the effect of a six fermion interaction leads to an enhancement of u\mathrm\text\ensuremath-d superconductivity, due to nonvanishing strange quark-antiquark condensates, such an enhancement will be absent at higher densities for u\mathrm\text\ensuremath-s or d\mathrm\text\ensuremath-s superconductivity due to early (almost) vanishing of light quark-antiquark condensates.
