HPP is a nonthermal
lethality
process that kills
harmful bacteria
while preserving the
nutritional benefits
of the product. "
Steven Moore, Scoular
Thermal processing
Radio frequency (RF) pasteurization is
an alternative method available to pet
food processors to help control pathogens.
It's a thermal process utilizing the
moisture content of the product to generate
volumetric heat throughout the
bed depth or final packaging. RF is a
non-ionizing form of energy the same as
microwave, explained Lisa Mitchell, vice
president of marketing for Millis, Mass.-based Radio
Frequency Co.
Ingredients or even finished product are sent through
the RF applicator for a validated and targeted temperature
and hold time. Time and temperature are product dependent
and determined through validation testing. Each RF
system can be programmed with multiple " recipes " for
numerous ingredients or products. All data is recorded
for each product run.
" With conventional heating, the outside layers of the
product may have to be heated to higher temperatures to
get the appropriate pasteurization temperature into the
center of the product mass, " Mitchell said. " But the long
wavelengths of the radio frequency heat up the material
volumetrically and very rapidly. "
According to the company, " The product is conveyed
through the applicator [machine] and is heated to the
target temperature rapidly and uniformly. The applicator
cabinet is also conventionally heated to prevent radiational
cooling. With bulk processing it then enters the
heat retention zone, using conventional heating, for the
required hold time. With product processed in-bag, the
hold time can be validated on the repalletization and the
time the bags take to cool down. Processing in final packaging
prevents the opportunity for re-contamination.
Radio Frequency machines can often provide 5-log
reduction at lower temperatures in a shorter amount of
time than conventional heating methods.
" We can achieve a 5-log reduction at between 185°F
and 195°F, which is typically a lower temperature than
more conventional thermal processes, " Mitchell explained.
" And it doesn't take the typically long processing
