In this study the samples covered with rosemary leaves showed
an increase in the stability of the lipid fraction when compared with
early maturation cheeses or uncoated cheeses. The lipid fraction of
the coated cheeses showed greater stability, with higher degradation
and oxidation temperatures when the thermo-oxidative process
was accelerated. The sample containing rosemary had an
average increase of 53% in the value of the activation energy
associated with the oxidation of the samples.
FTIR showed the release of the gases in the first two steps, which
were release residues of the solvent used in the extraction of the
samples (CH3CH2OH), and in the second stage a gas mixture was
observed more effective form CO2 and CO, which was attributed to
CH and COOH stretching.
