Background: Meat products contain sodium nitrite. Consumer demand for natural preservatives instead of synthetic ones in foods has been growing in recent years because of their safety. Today, good quality meat products are produced worldwide, and in addition to desirable sensory properties, they are cheaper than fresh meat. Sausage with 40% red meat is one of these products which can partially meet the need for animal proteins. Methods: In this study, sodium nitrite was replaced by lycopene pigment at concentrations of 200, 400 and 600 ppm in 40% meat sausage. Physicochemical properties of sausage samples including moisture, protein, ash contents and pH value were measured according to National Standard. Microbial tests (Clostridium, mold, yeast and Clostridium perfringens count) were performed according to National Standards. The colorimetric lightness index (L*) of the sausage samples was measured. Sensory properties (smell and taste) were compared with control sample (40% meat sausage contain 120 ppm sodium nitrite) after 30 days of storage. Data were analyzed using Duncan's one-way analysis of variance at 95% confidence level through Minitab 16 software. Results: After 30 days of storage, no significant (P>0.05) difference was found in physicochemical properties, microbial tests, lightness index (L*), and sensory properties among the samples. Conclusions: Since no significant difference was observed in microbial load and sensory scores between sausage sample containing 600 ppm lycopene pigment and control sample, 600 ppm lycopene pigment can be used in sausage formulation.
