............"Miller says results of a 2005 National Cattlemen’s Beef Association (NCBA) survey indicate that around 90% of all beef meets the “acceptable†level for tenderness. That’s determined by Warner-Bratzler shear force (WBSF); beef cuts that require more than 4.9 kilograms, or 10.8 lb., of force to shear are a problem for most consumers.
“When 90% of the beef in the U.S. meets tenderness thresholds, flavor is going to become the most important driver,†he says. Although more research needs to be done on what factors influence beef’s taste, Miller has an idea where to start.
“We know marbling has a big effect on flavor,†he says. “A higher degree of marbling increases the flavor,†he says.
The Texas Tech take-home point, Miller says, is that consumers don’t just want tender beef; they want tasty, tender beef. The industry must maintain its focus on assuring tenderness while facing the fact that it must add more focus on marbling".
==================
Other studies strongly suggests that more marbling is obtained with............age.
