Why Is Marbling Desirable In Meat

When beef graders yes there are people who grade beef for a living are grading beef they specifically look at amount of marbling in the ribeye muscle between the 12 th and 13 th ribs.

Why is marbling desirable in meat.

Heritability is the part of the variance in an observed trait after allowing for environmental factors. Marbling is important to steak because it adds flavor the right kind of flavor juiciness as it melts into the steak when cooking and tenderness because the fat is much more tender than the muscle fiber in the steak. When cooked hot enough usually upwards of 130 f the marbling in steak begins to melt and coat the muscle fibers surrounding it. Also called intramuscular fat marbling adds flavor and is one of the main criteria for judging the quality of cuts of meat.

Firmness of muscle is desirable as is proper color and texture. Looking at the upward trend in marbling expected progeny differences epds it s clear genetic selection is effective. In general the more marbling it contains the better a cut of meat is. In fact the temperature at which marbling melts is not far above room temperature.

The presence and type of marbling in meat is important for several reasons. Marbling melts while the meat cooks carrying flavor throughout the meat and while keeping it tender and juicy. Steaks and other cuts of meat with a lot of marbling mostly come from the loin region of the animal. Excess calories from the cow s diet get stored here in the form of fat.

Producers selecting for quality may already know marbling is moderately to highly heritable averaging near 45. This is on the back of the animal where the muscles get very little exercise in comparison to the legs shoulders and rump. Desirable ribeyes will exhibit an adequate amount of finely dispersed marbling in a firm fine textured bright cherry red colored lean. Marbling is what gives good beef its desirable silky texture.

The marbling keeps the meat moist so natural juices don t evaporate in the pan. Marbling is so named because the streaks of fat resemble a marble pattern. Marbling keeps the meat moist during cooking so natural juices don t evaporate in the pan. When you have heavy marbling and it s the right kind of marbling you have a superior steak on your hands.

As the meat cooks the fat melts. Fat is far more tender than muscle fiber in steak. The result is a far tastier steak. Choice has less marbling than prime and select has the least marbling of all.

When cooking marbling adds flavor and juiciness as the fat melts into the steak. As an animal matures the characteristics of muscle change and muscle color becomes darker and muscle texture becomes coarser.
