Phenolic compounds were applied in a sausage formulation as a substitute for artificial sodium erythorbate used as antioxidant. Five assays were prepared in which sodium erythorbate control at 0.05?g/100?g was replaced with a hydrosoluble mixture containing caffeic acid?+?carnosic acid (47%?+?53%) and a liposoluble mixture containing quercetin?+?rutin (67%?+?33%) in two final concentrations (0.05?g/100?g and 0.08?g/100?g). Physico-chemical, color, texture, and sensory parameters were measured on the first day and after 45 days of storage at 4?°C. All phenolic compound mixtures were able to maintain oxidative stability in the sausages when measured by the malondialdehyde concentration, which was expressed as TBARS. The mixture containing quercetin?+?rutin at 0.05?g/100?g showed lower malondialdehyde formation after 45 days of storage, and no sensory differences from the sausage adopted as control.
