president and co-founder, FoodSafe Technologies, Deer
Park, N.Y., shared several clean label alternatives being used
in pet food and treat products, including mixed tocopherols, rosemary extract, vegetable oils from canola, sunflower
and soybean, and even certified natural citric acid.
" A downside to natural ingredients is that some are less
stable and/or more expensive, " Asquith said. " Colors are a
good example - natural colorants tend to be less effective
than synthetic. Another example is propylene glycol - it's
more effective than [natural] glycerol at binding water in
soft, moist treats. "
Variability in certain nutrients can be caused by several
factors, including the stage in which they were harvested,
storage conditions, processing conditions and individual
ingredient sensitivities.
" For example, the variability and stability of vitamins
in fruits can be high due to the reasons mentioned above, "
said Trevor Faber, Ph.D., companion animal nutritionist,
Trouw Nutrition, Highland, Ill. " Once incorporated into
the food, the vitamins will have a lower stability than synthetic vitamins, which can affect the nutritional adequacy
of the food over the long shelf-life. "
According to Jean-Charles, natural antioxidants can
require higher PPM [parts per million] rates, meaning a
higher concentration of the nutrient per measurement,
which can cost more for the manufacturer and result in a
higher-priced finished product.
" Acceptance into the market, the expense, labeling and
effectiveness of the new product are all challenges, " added
Kent Cooper, co-owner, ingredients and processing, Evolve
Consulting Group. " Chemical/synthetic options in many
cases are tried and true, making it hard to provide enough
data to change the industry perspective on new options. "

Cost is also a barrier but, for companies that can make
ends meet, also a potential benefit.
" When customers demand these types of products, they
are typically willing to pay for them as well, " explained
Eric Allphin, vice president, business development, Renew
Biomass, Aurora, Mo. " This affords the opportunity for
profits within a company. "
There are also operational and marketing benefits to incorporating non-synthetic and non-chemical ingredients
into a pet food formulation.
" The main benefit of formulating with these ingredients
is the marketing message stating that they only use 'natural' ingredients, or their product is free of some substance, "
Faber said.
Formulations that include non-synthetic colorings can allow processors more flexibility in scheduling, less clean-out
waste, and reduced risk of cross contamination, according to
Schole. Fernandez pointed to a myriad of health benefits that
could be attributed in part to the inclusion of polyphenolrich botanical extracts in pet food, including improved antioxidant capabilities, inflammatory response support, joint
health, gut health and immune system support.
" In addition to the health benefits, polyphenol-rich botanical ingredients can also be used for preservation of pet
food and treats and can naturally help to extend the shelf life
of lipids used in these products, " she said. " We are also seeing
increased interest in using natural, plant-based ingredients
as flavor and sensory additives, adding palatability and helping to achieve improved intake and overall diet efficiency. "

Knowing your options
There are several suppliers actively exploring this space and
offering new non-chemical and non-synthetic ingredients
to pet food processors.
Trouw offers two ingredients in this category, one
of which is its Beneo Inulin ingredient for dog and cat
food formulations. The ingredient is a naturally derived
source of chicory inulin, in which chicory root pulp goes
through a hot water extraction process to create concentrated inulin.
" This provides a variety of fructooligosaccharide chain
lengths that have greater microbial benefits than synthesized fructooligosaccharide products, " Faber explains.
Fructooligosaccharides (FOS) can serve as a source of
