However, according to some literature data, the effect of rapid chilling on technological quality parameters of pork is limited. Kerth et al. (2001) observed reduction in PSE meat incidence in loin and ham of stress sensitive pigs after accelerated air chilling, but not in stress resistant pigs. On the contrary, Hambrecht et al. (2004) concluded that rapid air chilling cannot prevent the appearance of inferior pork quality caused by high preslaughter stress. Similarly, Eilert (1997) stated that more rapid chilling procedures will not prevent PSE because, in severe cases of PSE, the damage has already occurred before the carcasses enter the cooler.
