The FDA identifies processing aids in pet foods as:
substances added to a food during processing but removed in some manner before packaged in finished
form; substances added to a food during processing and
are converted into constituents normally present in the
food and do not significantly increase the amount of the
constituents naturally found in the food; and substances
added to a food for their technical or functional effect in
the processing but are present in the finished food at insignificant levels and do not have any technical or functional effect in that food.
" If an ingredient is deemed a processing aid, it does
not have to be declared on the end product's ingredient
statement, " said Robert Ames, senior business development manager, Corbion, Lenexa, Kan.
To clarify, the additive must either be GRAS or an approved food additive. However, if the additive meets the
definition of processing aid, it's exempt from declaration. It is always best to work closely with regulatory to
ensure compliance.
" The purpose of any processing aid is essentially to
help create a more efficient manufacturing process, and
in any industry, that is a critical aspect of staying competitive, " Ames said. " But determining what is considered a processing aid and what is not isn't always simple.
" In the pet food industry, a processing aid may help
prevent sticking and improve the flowability of the product, " he continued. " Without that help, production may
be significantly slower or shut down altogether to clear
blockages in equipment. It can help stabilize a process
or make it safer in some way, but its use should not
change the end product itself in terms of performance
or nutrition. "
Kent Cooper, co-owner, Evolve Consulting Group,
Fremont, Neb., said, " If a treat manufacturer is having
trouble getting dough to release from the mold, they
might add a processing aid to help the dough to release

easier. In high-moisture treats such as a jerky or snack
stick, a processing aid will need to be used to help with
water binding. "
Cellulose powder and silica are common processing aids. They function as anti-caking agents and may
be present at very low levels on one or more ingredients
used in the pet food formula. When part of the total formulation, inclusion level is insignificant.
" In many pet food applications, microencapsulation
is a unique enabler technology for better processing
control and innovative product development, " said Eric
Altom, Ph.D., technical nutritionist, animal nutrition
and health division, Balchem Corp., New Hampton, N.Y.
" Encapsulation, or specifically microencapsulation, is
used to segregate a raw material from a product or process with the goal to prevent raw material degradation,
or pre-reaction of problematic materials in a process, "
Altom added. " This could be to control a reactive raw
material, like an organic acid, from interacting with
other ingredients. "
Balchem offers encapsulated sodium bicarbonate,
which alters the leavening reaction in a variety of products to modify density, increase porosity, and otherwise
manipulate piece size and structure. This processing aid
is easily applied to baked treats to improve texture, increase overall treat size or decrease the energy density
of the treat.
" In extruded pet foods and treats, a variety of emulsifiers can be useful for improving the flowability of the
product in processing and avoiding stickiness that can
cause manufacturing problems, " Ames said. " They help
create a dough of the right consistency with just the right
amount of lubrication to facilitate efficient processing.
" Emulsifiers can also play a critical role in achieving
quality and processing efficiency when shifting between
formulations that contain very different proportions of
grain, meat, vegetable or other components, " he added.
