Quark-antiquark condensation has been investigated in the framework of the NJL model. Using the Fermi momentum of the particle as cut-off parameter the gap energy and coherence length for meson condensates have been studied. The Fermi momentum for the 
condensate has been extracted considering the coherence length ξ ∼ 1 fm. The results are compared with existing data. Some interesting observations are made.
