Abstract
A process includes contacting a feathered poultry carcass with an ammonia-based treatment material to increase the pH at the skin of the carcass and thereby effect a loosening of the feathers on the carcass. After the contact with the ammonia-based treatment material, mild heat may be applied to the feathered carcass to further loosen the feathers. The prepared feathered carcass is then defeathered in a suitable defeathering process. Ammonia may be removed from the carcass before, after, and/or during defeathering. The defeathered carcass is then passed on for further processing to produce the final poultry product.
