HIGH

pressure perks
HPP systems offer advantages for pet food and treat processors.

High Pressure Processing or HPP is often used in raw pet
food and in freeze-dried pet food and treats because the
products are not heated to a temperature that would kill
bacteria. By incorporating HPP into the production process, pet food and treat processors can benefit from a number of distinct advantages, including improved product
safety and increased shelf life.
HPP is used in two primary ways by pet food and
treat processors.
" The first is to treat raw products used in the production of pet food products to ensure there are no bacterial
issues in the materials, " said Joe Neeb, vice president of
operations, MiracleCorp Products, Moraine, Ohio. " The
second is to treat cooked refrigerated pet food post packaging to ensure product safety and extend shelf life. "

Benefits of HPP

Improved product safety is a major benefit of HPP for pet
food and treat processors.
" The primary advantage in using HPP is to have a
pathogen-free raw material to ensure the safety of pets and
pet owners, " explained Errol Raghubeer, PhD, senior vice
president, science and technology, JBT Avure, Erlanger,
Ky. " Generally, raw meat materials can have a high load
of pathogens, particularly Salmonella, Listeria monocytogenes, pathogenic E. coli bacteria, and Campylobacter.
Although viral concerns were not necessarily the focus for
using HPP in pet foods, it is important to note that HPP

is effective against several types of viruses including coronaviruses. And in the current global health crisis, HPPtreated pet foods can be used as an additional protection
for pets and pet owners. "
HPP is well suited to raw pet food and freeze-dried pet
food and treats as the process does not affect product integrity. As HPP is a non-thermal process, the basic ingredients
are not affected nor develop a cooked flavor or color, explained Chris Holland, managing director, Holmach Ltd.,
Stamford, United Kingdom. In addition, HPP does not affect the biochemical profile of raw pet food.
" HPP does not affect vitamins and bioactive compounds
and therefore, biochemically the product retains its rawness
whereas heat and other processes will affect these nutritional materials, " Raghubeer added.
Many processors are also using HPP to ensure product
safety post-packaging.
" Pet food and pet treat companies are using HPP to
process in bulk prior to further processing, " said Tom
Woodward, chief commercial officer, Universal Pure,
Lincoln, Neb. " However, brands are also using HPP for
the final product just prior to shipping in the retail or
specialty food channels. The use of HPP offers an outstanding element of food safety and provides both the
brand and ultimate user with a sense of security. The
use of HPP of pet products can significantly reduce the
risk of food borne pathogens further down the distribution chain. "

As demand for
" fresh " pet food and
treats grows and
the infrastructure
expands to support
more refrigerated
and frozen, minimally
processed products,
HPP usage has the
potential to increase
significantly.
