ABSTRACT:
Prior to slaughter, poultry are caused to undergo anoxic convulsions by exposure to an atmosphere for a sufficient period of time to lose consciousness. The poultry are then slaughtered. After slaughter, the poultry are chilled and then deboned or portioned. It is found that deboning or portioning can be performed within four hours of slaughter, instead of the conventional period of twelve hours or more, without adversely affecting the quality of the resultant meat. This result is attributed to the anoxic convulsions causing glycolysis in the pectoral and other muscles of the birds.
