Along with decisions between wet
versus dry palatants, formulators have
an increasing range of options for
influencing pet food palatability as new
technologies are developed and refined.
One such pet food technology is the use
of vacuum coating to apply palatants.
A vacuum coater is a batch mixer
that sucks the air out of a kibble
chamber before palatants and fat are
applied. After application, the vacuum
is slowly relieved, which draws the fat
and palatant coatings more deeply into
the kibble than under normal atmospheric conditions.
"It allows higher amounts of fat to be
added to the kibble, which has a role in
palatability and nutrition," said Stirling.
"For the palatant application to
be successful, vacuum coating must
be part of a sequence process," he
said. "For instance, if you are using
a dry palatant, the vacuum must be
controlled so that fat remains on the
surface to hold the dry coating."
These emerging palatability
technologies aim to tantalize pets'
senses and thereby increase their
attraction to the food. Yet for many
animals, especially in the United States,

Another innovation in palatability
involves alterations to the pet food
drying process. In 2015, Diana Pet
Food, LIS, Triballat‐Noyal and Clextral
combined investments to set up an
extrusion porosification technology
(EPT) pilot plant in Europe.
EPT involves a kibble drying
innovation developed and patented by
Clextral, Champion said. This process
involves novel porous powders with
improved functional properties, such
as rehydration and flowability. Also,
these powders used in the EPT process
should enhance the aromatic profile
to boost pets' satisfaction with their
sensory experience of eating.

overindulgence in that tempting pet
food contributes to obesity and related
health problems. To address these
issues, palatability can play a key role.
"Weight management diets are
sometimes less palatable to the pet,

"As pet owners migrate toward pet foods with more humanization

strategic advantage. As an extrusion
