Sensitive Catalase Test for End-point Temperature of Heated Chicken Meat

Ang CYW, Liu F, Townsend WE, Fung DYC


Our improved method enables detection of catalase-related activities as a biochemical marker for estimating cooking end-point temperature (EPT). The broad range of inactivation temperature in chicken tissues was first determined to be > 68°C and =0.99 after 45 min when incubated at 23°C. This probability decreased to >=0.03 as EPT increased to 71°C. Higher incubation temperatures (37°C) increased the probability of positive results.
