The food industry is developing alternative approaches to
conventional processing technologies, including high pressure
processing (HPP), to meet consumer expectations for increased
food safety, extended shelf life and improved food quality .
Although the application of 400–800 MPa inactivates most pathogenic
and spoilage bacteria (Torres and Velazquez, 2008), the
inactivation of bacterial spores has been a major challenge. For
example, no significant inactivation of spores of 6 Bacillus species
was obtained when these spores were treated with 980 MPa for
40 min at room temperature (Stewart et al., 2000).
