used a
HPP to treat strawberry juice at 600 MPa with an initial chamber
temperature about 25 C and reported a temperature increase of
18 C, or 3 C per 100 MPa. According to our results, the temperature
increase in strawberry puree was dependent on the applied
pressure. The thermal impact may become an important factor for
the HPP pasteurization in certain conditions, which include the
initial temperature, heat capacity of foods and etc. It is highly recommended
that food temperature profile in any HPP operation be
properly investigated to achieve the desired foodborne pathogen
inactivation results.
