We analyze the phase diagram of a 3-flavor Nambu-Jona-Lasinio model at finite temperature T and chemical potentials {mu}{sub u},{mu}{sub d},{mu}{sub s}. We study the competition of pion and kaon condensation and we propose a physical situation in which kaon condensation could be led only by light quark finite densities.
