A tempering treatment method whereby the temperature of meat, which involves carcass prepared by slaughtering cattle or poultry and sterilizing and washing, is lowered as close to the ice storage temperature as possible to prevent a temperature rise caused by the actions of enzymes contained within the meat before transporting the meant to a refrigerated storage, which comprises surface-freezing the meat by blowing a cold air stream at about -20 to about -40oC to the meant before conducting the tempering treatment, thus allowing the generation of freezing latent heat in the subcutaneous part owing to the surface-freezing (freezing the subcutaneous tissue), and then rapidly lowering the core temperature inside the meat due to the latent heat released at the melting of the freezing latent heat to thereby conduct the tempering treatment at a temperature of 0 to +15oC.
Procédé de traitement par trempage consistant à abaisser la température de viande (carcasse issue de l'abattage de bétail ou de volaille avec stérilisation et lavage) aussi près que possible de la température de stockage de glace pour empêcher une montée de température sous l'effet d'enzymes contenues dans la viande avant le transport de la viande vers un stockage réfrigéré: on effectue une congélation de la viande en surface en soufflant de l'air froid entre environ -20 et environ -40oC avant le traitement par trempage, ce qui produit une chaleur latente de congélation dans la partie sous-cutanée en raison de la congélation de surface (congélation de tissu sous-cutané), et on abaisse ensuite rapidement la température à coeur dans la viande suite à la libération de chaleur latente au moment de la fusion de la chaleur latente de congélation pour conduire le traitement de trempage entre 0 et + 15° C.
