Abstract: The SU(3) generalized Nambu - Jona - Lasinio (NJL) model is consideredby means of the Cornwall - Jackiw - Tomboulis (CJT) effective action. This method provides a very general framework for investigating many important non- pertubative effects: quark condensate and mesons, thermodynamical quantities at finite tempera­ture. It is shown that the mixing of flavors of u, d and s quarks exists in this formalism. The gap equations, which are directly obtained from the effective potential involved the quark condensate.
