Abstract
Method and apparatus for processing slaughtered poultry that is conveyed in a slaughter line of a slaughter house, in order to establish at the start of said slaughter line whether the poultry was alive or dead on arrival at the slaughter house. Such can include the detection of a body parameter of the slaughtered poultry when the poultry is suspended by the legs in the slaughter line after stunning said poultry, and wherein an absorption spectrum of blood of the slaughtered poultry is determined.
Claims23
A method of processing poultry conveyed in a slaughter line of a slaughter house, comprising:
- stunning the poultry;
- obtaining noninvasively at the start of said slaughter line an absorption spectrum of blood of the slaughtered poultry for wavelengths between 200 nm and 1000 nm at non-feathered skin or skin parts of the poultry;
- and
- determining, from the absorption spectrum, whether the poultry was alive or dead on arrival at the slaughter house by comparing the absorption spectrum of the blood of the slaughtered poultry with absorption spectrum for deoxygenated blood.
A method of processing poultry conveyed in a slaughter line of a slaughter house, comprising:
- stunning the poultry;
- obtaining noninvasively at the start of said slaughter line an absorption spectrum of blood of the slaughtered poultry for wavelengths between 200 nm and 1000 nm at non-feathered skin or skin parts of the poultry and
- determining, from the absorption spectrum, whether the poultry was alive or dead on arrival at the slaughter house, wherein the determining comprises ascertaining a level of deoxygenation of the blood of the slaughtered poultry using the absorption spectrum of the blood of the slaughtered poultry and an absorption spectrum for deoxygenated blood.
