Spray-chilling system in the initial cooling process of swine half carcasses.

This research was carried out with the objective of evaluating the effects of using a chilling water sprinkler system during the cooling process of swine carcasses on the quantitative and qualitative parameters of carcass and meat. A total of 220 swine carcasses were divided in a completely randomized experiment and two treatments: (1) CONTROL, no water spraying; (2) SPRAY, with water spraying during cooling. Surface and internal temperature of carcasses throughout the cooling process, initial and final pH, and microbiological analyses of carcass surface were evaluated.
