Composition of MeatProtein
Another group of substances related to proteins are the Pyrimidines, and Nucleopeptides have very little nutritional value
do have the natural ability to excite gastric juices. Combined with fats,
primarily responsible for the flavor and aroma of meat.found more abundantly in older animals
more concentrated in more frequently worked, or tougher muscles.
gives “Gamey” meat that “Gamey” flavor

Muscle BreakdownMyofibrils Smallest from of the muscle
Hair like strands surrounded by collagen
FiberA bundle of _myofibrils, held together by a sheath of collagen
Muscle A bundle of fibers, held together/in place by reticulin

Composition of MeatFatFAT IS NOT FLAVOR!
IT IS the carrier of flavor.

Composition of MeatThere are Three Types of Fat
1.Subcutaneous is found on the exterior of the muscle
2.inter-muscular is found on the Interior of the muscle and is known as fat distribution, or marblingGood _Marbling will look like evenly drawn white
lines equally distributed throughout the interior of the muscle.
The grading of meat is based on thisThe more evenly distributed the fat is, the more
moist the meat will be.

Composition of MeatFat2. inter-muscular
Animal Fat is Saturated Fat distinguished by the fact that it is solid at room temperature
As heat is applied to the meat, the fat is liquefied from its solid state, and helps to lubricate the myofibrils of the muscle resulting in a much more texturally advantageous piece of meat.
Bad Marbling will look like a large pocket of fat unevenly distributed, and usually appears in one section of the muscle.

Composition of MeatFat3. KHP Fat
Kidney Heart and Pelvic Fatwhich is the fat that surrounds the organs and
protects them from slamming into the skeletal system.
Also determines the quality of the life once lead by the animal
