Consumer sensory evaluation, fatty acid composition, and shelf-life of ground beef with subcutaneous fat trimmings from different carcass locations. Academic Article uri icon


  • Brisket, chuck, plate, flank, and round subcutaneous fat trim were used to produce ground beef patties then evaluated for color, lipid oxidation, fatty acid composition, volatile chemical compounds and consumer sensory evaluation. Color, TBARS, consumer sensory evaluation, and cook/freezer loss did not differ (P>0.05) among carcass fat locations. Percentage stearic acid was lower (P=0.044) in the ground beef using brisket fat than using the chuck and flank fat. Patties made with brisket fat were higher in cis-vaccenic acid (P=0.016) and the saturated to monounsaturated fatty acid ratio (P=0.018) than all other sources of subcutaneous fat. Butanedione was highest (P=0.013) in patties using flank and plate fat. Ground beef with brisket fat was higher (P=0.003) than all other sources for beefy aroma. Altering the profile of non-polar, triglyceride fatty acids has no effect on sensory flavor or major volatile chemical compounds.
