Abstract
Salmonella spp. or Listeria innocua containing chicken patties were processed via a pilot‐scale air‐convection oven to a final temperature of 55 to 80 °C. Thermal processing was conducted at an air temperature of 149 °C, an air velocity of 7.1 to 12.7 m3/min, and a wet bulb temperature of 39 to 98 °C. The cooking time was correlated with cooking conditions using a standardized least square regression model. The models were developed to correlate cooking time and the thermal inactivation of Salmonella or Listeria with cooking conditions. The thermal lethality of Salmonella and Listeria increased with increasing product temperature and wet bulb temperature. This study bridged the gap between laboratory studies and commercial applications and will help commercial processors to evaluate and validate their thermal processes.
