We study the baryon number susceptibility in the Nambu-Jona-Lasinio (NJL) model within the mean field approximation. We find that the naive extension of the NJL model to the finite temperature situation cannot reproduce the correct low temperature behavior of the baryon number susceptibility. We propose the color singlet projection in order to remove the colored quark states from the thermodynamic potential. We find that the color singlet projection considerably improves the low temperature behavior of the susceptibility.
