Since large amounts of sodium nitrite (NaNO2) are reduced during the shelf life of meat products, and given the difficulty in maintaining its stability in these products, the use of encapsulation techniques increases the action time of this additive to guarantee food safety. Thus, since NaNO2 is a mandatory food additive in mortadella formulations, the objective of the study was to evaluate different wall materials for the microencapsulation of NaNO2 in a spray dryer for further evaluation and monitoring of the agent encapsulated in mortadella during 60 days of storage at room temperature (25 ± 2 °C). The spray drying process was performed via atomization, testing 4 different compositions using porcine collagen, gum arabic (GA), and maltodextrin (MD) with NaNO2. The 10% GA + NaNO2 and 5% GA + 5% MD + NaNO2 samples had encapsulated NaNO2 yields of 46% and 42% (w/w), respectively. The application of microencapsulated materials on mortadella gave the product a better stability in the NaNO2 reduction reaction, remaining until the 50th day with NaNO2 residues above 50 mg/kg, while the control sample reached this level after 30 days of shelf life. Therefore, the application of NaNO2 capsules in mortadella can be an alternative for promotion of physicochemical and microbiological stability and is of fundamental importance for industrial applications.
