Mortadella-type sausage manufactured using mechanically deboned chicken meat were reformulated replacing MDCM with increasing amounts of MDCM protein hydrolysates (10%, 20%, and 30%), and their physicochemical, microbiological, and sensorial characteristics were evaluated for 60 days of storage at 4 °C. The higher substitutions resulted in sausages more susceptible to lipid oxidation with higher TBARS values during storage; however, these values were lower than the organoleptic perception threshold. The sausages were darker and less red, with lower lightness (L*) and redness (a*) values than those of the control treatment. They had soft texture, which was evidenced by both the instrumental and sensory analysis. Therefore, the formulation containing 10% of MDCM protein hydrolysates proved to be the most suitable for mortadella-type sausage elaboration.
