2018 National Beef Flavor Audit: Consumer and Descriptive Sensory Attributes

Abstract

Beef flavor has been identified as a driver of consumer acceptability; however, little is known about variability of flavor in major United States retail beef cuts. Four beef cuts (chuck roast; top sirloin steaks; top loin steaks; and 80/20 ground beef) were obtained from retail stores (n=30 per cut per city) in Miami, Los Angeles, Portland, New York, and Denver during a 2-mo period in 2018. Production systems or package claims were documented. An expert trained flavor and texture descriptive attribute sensory panel evaluated beef flavors, aromas, and textures (n=10 cuts per city or 50 cuts evaluated). Consumer sensory panels in Fort Collins, CO (n=10 per cut/city), and Lubbock, TX (n=10 per cut/city), evaluated beef for overall liking, overall flavor, beef flavor, grilled flavor, juiciness, and texture liking. Ground beef patties (GB) were more intense (P<0.0001) in brown, fat-like, green hay-like, and sour milk/sour dairy flavor aromatics and salty and sweet basic taste than steak or roast cuts. Additionally, GB had the lowest levels (P<0.0001) of bloody/serumy, metallic, and liver-like flavor aromatics. Chuck roasts had the lowest levels of (P<0.0001) beef flavor identity, brown, and roasted flavor aromatics and salt and umami basic tastes. Top sirloin steaks were lowest (P<0.0001) in fat-like flavor aromatics and most intense (P<0.0001) in burnt, cardboardy, bitter, and sour attributes. Top sirloin steaks and chuck roasts were more intense in metallic and liver-like (P<0.0001) flavor aromatics. Consumers rated chuck roasts lowest for overall, overall flavor, grilled flavor, and juiciness liking (P<0.04). GB and top loin steaks had the highest consumer texture liking (P<0.0002). Beef descriptive flavor and texture attributes were related to consumer liking, and negative flavor aromatic attributes were identified. Variation in beef flavor attributes were reported in retail beef cuts and ground beef that impact consumer liking.
