The Nambu‐Jona‐Lasinio model as a particular model of quark flavour dynamics is bosonized in the low‐energy regime using a generalized heat kernel expansion with local mass scale. The resulting effective meson Lagrangian defines a chiral soliton model, the solutions of which show a partial restoration of chiral symmetry inside the soliton.
