FORMULATION

hemicellulose and lignin, resulting in underestimations
of the true fiber content. Crude fiber does not account
for the soluble fibers in an ingredient and provides little
information about the functionality and fermentability
of that ingredient or feed."
Since the turn of the century, the scientific community has gained a much better understanding of the many
varied forms of dietary fiber and their different roles and
benefits. The US Food and Drug Administration (FDA)
defined fiber - for the first time - on May 27, 2016,
as "non-digestible soluble and insoluble carbohydrates
(with three or more monomeric units), and lignin that
are intrinsic and intact in plants; or isolated or synthetic
non-digestible carbohydrates (with three or more monomeric units) determined by the FDA to have physiological effects that are beneficial to human health." There
is discussion that AAFCO may change the pet food fiber
declaration from crude fiber to dietary fiber to better
align with FDA's definition.
"This label change would require a switch from the
proximate analysis method to the total dietary fiber
method, which measures both insoluble and soluble
fibers," Faber says. "The total dietary fiber method provides the most useful information about how these fibers will affect the animal."
Dietary fiber is associated with varied physiological
responses in humans, many of which are believed to be
similar in animals. These benefits are often recognized as
being specific to the fiber's solubility.
Soluble fiber, as the term suggests, describes fiber that
is soluble in water. This includes beta-glucan, fructooligosaccharides (FOS), galactooligosaccharides (GOS), gums,
inulin, pectin, polydextrose, psyllium, some hemicelluloses and resistant maltodextrin. Many absorb water and
form a viscous gel that traps dietary cholesterol and bile
acids and carries them out of the body. This viscous solution has also been shown to trap carbohydrates, slowing their digestion and absorption. This may help prevent
wide swings in blood sugar level during the day, as well as
have an impact on the development of diabetes.
Some soluble fibers, such as inulin, FOS and GOS, are
not viscous, rather, they are fermentable. They function
as prebiotics to promote the growth of beneficial intestinal bacteria, positively impacting digestive health.
Top: Recently, sweet potatoes have gained in popularity among pet
parents and can be a high-quality source of fiber for formulators.

Middle: Ground miscanthus grass is one example of fiber that
delivers nutritional benefits but also offers a positive sustainability
story for brands. Renew Biomass
Bottom: Pets benefit from both soluble and insoluble fiber in their
diets and formulators can choose from an increasing number of
high-quality options. Fiberstar
