Abstract: Fish is recognized as a source of high-quality protein, unsaturated fatty acids, especially omega-3 fatty acids, as well as minerals and vitamins. This study aimed to develop a tuna sausage (Thunnus atlanticus) using chitosan gel and fish skin. Four formulations were developed, and their physical, chemical, and microbiological characteristics were evaluated. The products were packed in conventional polyethylene packaging and stored for 45 days at 5°C ± 1. The sausages showed low lipid content (around 5%), high protein content (approximately 20%), and about 3% ash. Microbiological analyses conducted for Escherichia coli, coagulase-positive Staphylococcus, and Salmonella spp. demonstrated that the final product was processed under appropriate sanitary conditions, as the results obtained were within the standards established by current legislation.
