Effects of lipid oxidation in cooked mutton on species‐related flavor and warmed‐over flavor (WOF) intensities were studied using various additive treatments and post‐cooking storage (versus no additive/no storage) as means to produce samples of varied lipid oxidation. Ground mutton was treated with 200 ppm sodium nitrite, 0.5% sodium tripolyphosphate, 0.05% sodium ascorbate, 3% sodium lactate, 0.002% propyl gallate, or water only (control), cooked to 74C, and aerobically stored at 4C for 0, 2, or 4 days. Nitrite‐treated samples showed the least lipid oxidation as determined by the 2‐thiobarbituric acid reactive substances (TBARS) and had more intense species‐related (muttony) flavor than all other treated samples. Some samples exhibited high TBARS after 4 days but were still rated “slight” for WOF intensity, probably due to the strong species‐related flavor that could have made WOF less perceivable. Accordingly, correlations, although statistically significant, were low between TBARS and WOF intensity or between species flavor intensity and WOF intensity.
Ground chicken breast and beef top round (semimembranosus) muscles were treated with CaCl2 (0.05, 0.10, 0.15, and 0.20% on final sample weight basis) and cooked to an internal temperature of 80C. Cooked samples were aerobically stored at 4C for 0 or 4 days and analyzed for 2‐thiobarbituric acid (TBA)‐reactive substances. Results indicated that CaCl2 can either inhibit or accelerate lipid oxidation in cooked meat depending on its concentration/meat animal species. TBA values of chicken samples were decreased by CaCl2 used at ≥ 0.1% of final weight. However, only beef samples treated with the highest CaCl2 level (0.20%) tended to have lower TBA values when compared to control samples (treated with deionized water only). CaCl2 used at low levels (0.05% for chicken and ≤0.15% for beef) tended to elevate cooked meat TBA values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
