With respect to the lipid oxidation of refrigerated lamb loin, which was measured using the TBARS assay (milligrams malonaldehyde per kilogram of the sample), no significant variations were detected among treatments (P N 0.05), and there were no interactions (P N 0.05) between the analyzed treatments and storage periods. However, there was a significant effect (P b 0.06) throughout the 28-day storage period. Regression analyses indicated a significant quadratic behavior (P b 0.06). According to the derived equation, the maximum TBARS index occurred at 17.78 days of storage at 1 °C, with a value of 0.54 mg malonaldehyde/kg of sample. This was followed by a decrease in the TBARS index at the end of the evaluated storage period. It is worth noting that the TBARS values observed throughout the study period remained low, with an overall mean of 0.35 mg malonaldehyde/kg of sample. This likely occurred due to the samples' low percentages of lipids (approximately 2.48%) that contained high levels of saturated fatty acids, making the samples less susceptible to lipid oxidation
