Cured pork shoulder was produced using different percentages of pulverized coriander (20, 40, 60, 80% and 100%) and various variables were evaluated (humidity, pH, fat, protein, nitrites and nitrates). In the physicochemical analysis, nitrite and nitrate levels in the pulverized coriander were found to be 7.29 and 8709.35 mg/kg respectively. In addition, variables such as humidity, fat and protein in the pork shoulder were measured following the corresponding NTE INEN regulations. The techniques used for the measurements were adequate: humidity by drying, fat by the Soxhlet method (NTE INEN 778), and protein by the Kjeldahl methodology (NTE INEN 781). The results indicated that the use of powdered coriander had a positive effect on the lipid profile (p_value < 0.000) and moisture retention of the cured pork shoulder; additionally, microbiological analyses confirmed the absence of pathogens such as Staphylococcus aureus, Clostridium perfringens and Salmonella, a relevant finding that supports the safety of the product. The inclusion of powdered coriander could be a viable alternative to improve the characteristics of cured pork shoulder while reducing the use of sodium nitrite. |
