1 Separable lean tissue weight (g) includes all lean muscle and organ tissue. Separable lean, %: [separable lean tissue (g)/pre-dissection cut weight (g)] × 100. 2 External fat weight (g) includes all fat located on the outer surface of the item. External fat, %: [external fat (g)/pre-dissection cut weight (g)] × 100. External fat was not present for liver, kidney, tongue, or bone marrow. 3 Internal fat weight (g) includes any fat which lies between lean tissue. Internal fat, %: [internal fat (g)/pre-dissection cut weight (g)] × 100. Internal fat was not present for heart, liver, or bone marrow. 4 Refuse weight (g) includes all bone and heavy connective tissue (including tongue skin). Refuse, %: [refuse (g)/pre-dissection (g)] × 100. 5 Tripe and testicles were not dissected due to the homogeneous nature of the products; the entire item was considered separable lean tissue.
