A rapid chill process for poultry carcasses

摘要

Poultry carcasses are chilled rapidly when exposed to a flow of gaseous air at a temperature in the range from about -50°C to about -120°C for a period of time in the range from about 1 s to about 60 s. The flow is directed over and into the body cavity of the carcasses. The carcasses are orientated in the flow such that the sternum of each carcass faces downstream. One advantage of the process is that the number of viable microorganisms present on the carcasses is reduced significantly while avoiding freeze-damage to the carcasses.
