INGREDIENTS
" Light is a challenge for certain pigments, " Martin said.
" It can fade some colors, such as turmeric and annatto, so
your packaging selection needs to account for this issue. "
Artificial or natural, adding color means adding costs.
This is especially true of natural colors, which are the
most unstable formats.
" Cost in use historically was a limitation, however,
now with our improved agronomy programs and increased
technology, colors are more affordable than in
the past, " Martin said.
If you are going to invest in adding natural colors, it is
smart to invest in preserving the hues throughout shelf life.
" Natural curing ingredients, such as cultured celery
powder and cherry powder, as well as natural antioxidants
like green tea, rosemary and acerola extracts, can aid in
color protection, " said Jenna Callahan, marketing coordinator,
Florida Food Products (FFP), Eustis, Fla. " Natural
antioxidants can inhibit rancidity, which in turn inhibits
color changes that may occur during oxidation. "
Even though dogs
and cats wouldn't
complain, pet
foods would look
unappetizing without
added color.

ral color ingredients, so Sensient has developed a deep
portfolio of heat-stable solutions for each color in the
rainbow appropriate for pet products. "
Many pet foods and treats are fortified. These ingredients
often contribute to a dark base color, which can
make it challenging to color.
" Recent trends in dog treats have emerged where bright
colors are being used in similar ways to human sweet
treats, such as frosting on baked biscuits, " said Alice Lee,
technical marketing manager, GNT USA, Dallas, NC.
" We offer brown, yellow, orange and purple hues made
from recognizable fruits and vegetables such as carrots,
peppers, turmeric and apple. Most of these colors are stable
to high temperature and high pH conditions.
" In high moisture products, such as aseptic, canned,
refrigerated and frozen pet food, liquid colors are often
preferred for ease-of-use but powder colors could
also be used as long as there is enough water for hydration, "
Lee said. " In some extruded low-moisture systems
where water must be managed, there may be a preference
for powder formats. "
Overcoming formulation challenges
As with all foods, for humans or pets, there are technical
challenges that must be addressed to maintain product
quality, including cost and stability.
" Oxidation can be a challenge for pigments like paprika
and beta carotene, " Martin said. " So when using
these colors you would want to make sure to include an
antioxidant in the formula. "
The pH of the product is a concern with some natural
pigments based on anthocyanins. The pH may impact
the final shade and stability. This is mostly an issue in
wet, fresh foods, where pH may change over time.

" Colors create contrast
and can brighten products
to make them look
healthier and meatier. "
Ashlee Martin, Oterra
Guldenpfennig added, " Color preservation in pet
foods and treats is generally done for the pet owner. If
the preservative does not have any harmful effect on the
animal, or better yet it has a potential positive effect,
then we have no concerns in adding color preservatives.
In addition, if the preservative is being used to protect
phytonutrients that add color to food items, such as lutein,
anthocyanins and zeaxanthin, then that is vastly
more valuable for the health of the pet. "
Colors are here to stay for pet foods and treats. The
consensus is that formulators will move away from synthetic
versions to natural colors, as pet parents demand
cleaner labels for their furry friends.
" The industry will continue to find new sources for
natural colors and will work to find better solutions for
greens and blues as they are more difficult to match with
natural colors, " Martin said.
Fox added, " Pet owners want products that look more
delicious and are better for their pets than ever before.
Bright, natural colors are a key component of this advancement.
Expanding the rainbow even further to include
more options for bold, bright, stable shades in the
pet space will further enable new product development
and innovation. "
