The aims of this study were to develop and characterize a fermented sausage produced with different percentages of mutton (from adult female sheep, over four years old) and additional native starter cultures. Three treatments of fermented sausage were prepared: (T1) 30% of mutton; (T2) 60% of mutton; (T3) 90% of mutton. Starter cultures Staphylococcus xylosus LQ3 and Pediococcus pentosaceus P38 were used for the fermentation/maturation process. The parameters of aw, pH, acidity, weight loss, and monitoring of native starter cultures were evaluated during the fermentation and maturation processes. After maturation, the sausages were assessed for texture profile, color, lipid profile, volatile compounds and sensory analysis. Based on principal components analysis (PCA), it was verified that as mutton was added, there was a reduction of unsaturated fatty acids and an increase in red tonality. T2 showed higher ester production, which possibly positively influenced the acceptance of the aroma of the sausage. Sensorial analysis demonstrated that T2 had a greater tendency to be accepted. It can be concluded that up to 60% of meat from adult sheep can be used in the preparation of fermented sausages and that the use of native cultures attributed positive and typical characteristics to fermented sausage. •Mutton addition showed little influence on pH, acidity, Aw and weight loss.•Mutton addition increased saturated fatty acids and red tonality.•Mutton addition did not affect the LAB population.•Sausage with native culture and mutton showed high acceptance.•Results demonstrated the potential use of mutton in fermented sausages.
