Thermal processing of meat products with temperature shifts
would consequently increase the length of the processing regime,
increasing production costs and lowering product quality.
However, HPP treatments possess the advantage of acting homogeneously and instantaneously through the entire product, quickly
increasing the temperature of the product by adiabatic heating
(Torres and Velazquez, 2008). Therefore, in an effort to shorten the
germination step to less than 30 min, heat treatment was replaced
with HPP treatments as the inactivation step of germinated spores.
Spore-meat samples incubated with AK for 15 and 30 min at 55 C,
and subsequently treated with 586 MPa at 23 C for 10 min,
showed similar spore inactivation (w3 DR) as meat samples incubbated for a similar germination condition and treated at 80 C for
