  We investigate general aspects of the mass defects of strange stars in the
context of the Field Correlator Method, without magnetic field. The main
parameters of the model that enter the corresponding nonperturbative equation
of state of the quark gluon plasma are the gluon condensate $G_2$ and the large
distance static $Q{\bar Q}$ potential $V_1$. We calculate mass defects of
stellar configurations in the central density range $11<\log\rho_c<18$. In
general, the mass defects are strongly dependent on the model parameters. For a
large range of values of $G_2$ and $V_1$, we obtain anomalous mass defects with
magnitudes around $10^{53}\,$erg\,, of the same order of the observed energies
of gamma-ray bursts and neutrino emissions in SN1987A, and of the theoretically
predicted energies of the quark-novae explosions.
