opted for an atmosphere of 30% CO2:70% O2 as a balance between
rancidity development, stimulated by O2, and minimisation of
colour loss, observed under higher CO2 concentrations (40e80%), to
obtain a shelf life of 15 days. The difference to the 12 days determined
in our study may be related to the lower initial contaminations
(about 2.5 log CFU cm2) detected by Berruga et al. (2005)
on the rabbit carcasses.
