With a select cut, you should really consider a marinade to tenderize and make the meat more flavorful. A70 + Sm40 = Ch- Grade A is given to cuts with a 72% or higher percentage yield, whereas B and C grades are for lower percentages. A quality grade is a composite evaluation of factors that affect palatability of meat (tenderness, juiciness, and flavor). In beef, yield grades estimate the amount of boneless, closely trimmed retail cuts from the high-value parts of the carcass–the round, loin, rib, and chuck. 0000016832 00000 n Degree of marbling is the primary determination of quality grade. * Carcasses having B final maturity scores with Small and Slight marbling must grade U.S. Standard. fat that runs along the outside and through the meat should be as white as possible.
