title: Deboning broiler chicken legs and wings by dislocation of articular cartilage followed by stripping periosteum.
abstract: The yield of deboned meat is an important economic factor affecting the profit of the meat industry. This study was undertaken to determine whether the yield of boneless meat from broiler chicken leg (thigh and drumstick) and wing (drumette and winglet) is improved by introducing a new deboning method consisting of articular cartilage dislocation followed by stripping periosteum. A total of 44 broiler chicken carcasses were used in the deboning experiment. Right and left legs or wings from the first 22 carcasses were assigned to the new and ordinary hand deboning methods, respectively. For the remaining 22 carcasses, right and left legs or wings were assigned to the ordinary and new methods, respectively. The weight of residue, composed of bone and small amounts of cartilage and noncartilaginous tissues obtained after deboning, was then compared between the right and left legs or wings to see the difference between the 2 methods. The removal of tibia, fibula, humerus, radius, or ulna resulted in formation of a hollow in boneless meat obtained. There was no difference (P > 0.05) between the right and left legs or wings in the weight of residue obtained after deboning as expected. The weight of residue was less (P < 0.05) with the new method compared with the ordinary method in all chicken parts examined. The difference of residue weight between the 2 methods accounted for 10, 12, 14, and 21% of the weight of residue obtained by the ordinary method in thigh, drumstick, drumette, and winglet, respectively. The new method may be useful to deboners at home kitchens as well as the poultry meat industry. The present study also showed the development of a secondary ossification center at the proximal end of the carpometacarpus of chickens. This is, to our knowledge, the first report of development of secondary ossification center in chicken wings.
