With respect to the lipid oxidation evaluation, differ- ent TBARS values were observed between treatments at the beginning of storage (Fig. 1). Higher values were observed in the control treatment (no antioxidant), fol- lowed by 0.025 and 0.05% in the samples with added rosemary extract, indicating that oxidative reactions began during processing of the fermented sausages and are directly correlated with the antioxidant protective effect, since the control treatment showed higher values for TBARS, followed by the treatment with the lower level of antioxidant.
