- Mortadellas were produced by substituting up to 20% of meat for CO-treated blood.
- All of the mortadellas had high chemical scores and digestibility values.
- All of mortadellas had a PDCAA similar to, or higher than, those of fresh meats.
- Blood added mortadellas had PER and NPR values similar to those of the casein diet.
- Addition of CO-treated blood is nutritionally adequate for sausage production.
Porcine blood may be used in meat processing as source of protein for human consumption. This study aimed to analyze the chemical composition and protein quality (chemical score, protein digestibility-corrected amino acid score, digestibility, and protein efficiency) of mortadellas formulated by replacing different levels (0, 5, 10, 15 and 20%) of meat by carbon monoxide-treated (CO-treated) porcine blood. The mortadellas showed chemical score above 1, digestibility values above 90% and their protein digestibility corrected amino acid score (PDCAAS) did not differ (PÂ >Â 0.05). The protein efficiency ratio (PER) and the net protein ratio (NPR) values of the mortadella diets did not differ from those of the casein control diet. It is concluded that, regardless of the level of blood addition, mortadellas have high protein quality and digestibility. Therefore, from the nutritional point of view, meat replacement with up to 20% of CO-treated blood is nutritionally adequate for being used in sausage production.
