This study investigates the effect of the addition of plant-derived extracts (control, garlic extract or a combination of carvacrol, thymol, cinnamic aldehyde and eugenol oils extracts) to pig feedstuff and the reduction in salt content (NaCl or a mixture 60:40 sodium chloride:potassium lactate) on some physicochemical characteristics and consumer acceptability of dry-fermented sausages. Six different batches were formulated. The pH, color, lipid oxidation, and microbial counts were measured, and a consumer home test was performed. Both the use of a plant-derived extract and salt type affected the dry-fermented sausage characteristics. The low-salt batches presented a lower pH and higher microbial counts than the control. The salt reduction affected the color but only in the oil batches, resulting in higher L* and lower a* values. The oil batches presented the highest TBAR values (>1 mg/kg), suggesting that antioxidant compounds present into the meat were not bioavailable on the sausages or were missed during the curing process. The use of plant-derived extracts affected to consumer acceptability, whereas salt replacement did not. Oil batches scored lower than the other. From the current results, the oil extract would not be a recommended additive in pig feedstuff, especially when a low- salt strategy will be employed.
