“…The filtrate (1.0 ml), after proper decimal dilutions, was plated on E. coli/coliform Petrifilm™ (3M Microbiology Products Co., St. Paul, MN). The films were maintained at room temperature for 2 h to allow the injured cells to recover (Hsu et al, 2015(Hsu et al, , 2014 and then incubated at 37 C for 24 h. Colonies were counted with a 3M Petrifilm™ plate reader (Model 6499, 3M Health Care, 3M Center, St. Paul, MN) and converted to logarithms (base 10) of colony forming units per g (log 10 CFU/g).…”

“…HPP subjects food to an elevated pressure of 100e1000 MPa typically at temperatures below 60 C. The mechanism by which HPP inactivates foodborne pathogens include: 1) cell membrane alterations, a major factor to cause death (Moussa et al, 2009); 2) ribosome dissociation, to limit cell viability (Abe, 2007); and 3) cell structure damage or destruction (Hsu et al, 2014). There have been many studies on the use of HPP to inactivate STEC in ground beef, but most of those focused on a limited number of isolates, most of which were of the O157:H7 serovar, or a small number of non-O157:H7 isolates (Hsu et al, 2015;Jiang et al, 2015;Black et al, 2010;Schilling et al, 2009;Morales et al, 2008).…”

“…Ze względu na rosnące zapotrzebowanie nabywców na produkty o wyższej jakości, przy jednoczesnym dążeniu producentów do obniżania kosztów procesu, poszukuje się optymalnych rozwiązań w zakresie połączenia suszenia konwekcyjnego z nietermicznymi technikami obróbki wstępnej, takimi jak: wysokie ciśnienie hydrostatyczne [8], pulsacyjne pole elektryczne [9] czy ultradźwięki [21].…”

“…HHP is a method commonly used in the food industry to retain the texture and colour of a product, while inhibiting micro-organisms [ 21 , 33 , 34 ]. Since cooling in isochoric conditions reaches the same pressure than HHP, we would expect to retain these features too.…”
