High-pressure processing technology allows processors to
extend shelf life and protect pet food at the same time.

Products, such
as raw proteins
packaged in chubs,
are loaded into
baskets before
entering the highpressure
chamber
where up to 87,000
pounds per square
inch of water
pressure is applied.

High pressure processing (HPP) is a non-thermal food
preservation technology that uses extremely high levels of
isostatic pressure, typically up to 87,000 pounds per square
inch (psi), to inactivate harmful microorganisms and extend
the shelf life of food products, including pet food.
According to Daniela Soto-Castro, HPP food applications
specialist for Doral, Fla.-based Hiperbaric, baskets
are loaded with packaged raw pet food products, placed
into the high-pressure chamber, filled with water and
sealed. High-pressure intensifiers then pump water inside
the vessel, injecting up to another 15% water volume to
increase the pressure to 87,000 psi. Bacterial inactivation
occurs once the maximum pressure level is reached and
held during a specific holding time. Finally, the pressure is
released with the already processed products.
" After HPP, the product can be sold refrigerated or
frozen or sent to a clean room to be further processed
into bite-size shapes such as nuggets or patties, " she said.
" The processed products can then be sold refrigerated or

frozen or further dehydrated by heat or freeze drying. "
In the pet food industry, HPP can be applied to various
products, including raw and fresh pet food, to help
ensure food safety assurance through the 5-log reduction
of pertinent pathogens, such as Salmonella, Listeria
and E. coli, which can prevent recalls related to spoilage
or pathogen issues.
Additionally, it helps to retain nutritional quality
while preserving digestibility and nutrient bioavailability
and lets companies develop clean-label products
without compromising the quality or safety of the food.
Jeff Barnard, president at Universal Pure, noted the
company works with a growing number of fresh and frozen
pet food manufacturers to enhance their food safety.
" HPP is applied to the final packaged product, which
enhances food safety from the outside of the package
and all throughout the product, " he said. " HPP basically
crushes pathogens due to the extreme amount of
pressure applied - preserving the freshness and safety
