this same flavor. Regardless, in the feeding studies the
dogs consumed the foods readily regardless of treatment when offered singly. So flavor, while possibly not
preferred versus conventional ingredients, does not
appear to be an issue.
During processing of the diets containing increasing
levels of faba beans, the researchers' goal was to produce
foods with similar bulk density by making changes to the
extruder inputs (e.g., steam, moisture, screw-rpm). Some
differences among the treatments were noted as the faba
bean levels increased. Specifically, extruder retention
time increased and water at the preconditioner had to be
increased in order to improve starch hydration and swelling.
The 20% and 30% faba bean treatments required
more flow restriction (pressure in the extruder) to achieve
the target kibble expansion. Following drying, the
20% and 30% diets were denser and when assessed for
texture were found to be harder and tougher. This would
indicate that levels of dehulled faba beans up to 30%
could be used without major issues in processing. But at
the extreme end, kibbles might differ regarding texture
and hardness - something that could be a positive
under the right circumstances.
In this research, the authors also provided data regarding
the oligosaccharide content in the faba beans and the diets.
In the dehulled faba beans, the raffinose, stachyose and
verbascose content amounted to 1.2%. Even though this is
on the lower end compared to other pulses like peas and
lentils, when faba beans are included at higher quantities
(in excess of 20%) it may lower digestibility. Biogenic amines
were also measured and found to be low to non-detectable,
including low levels of histamine.

Promising results for faba beans
These studies represent some of the most comprehensive
work in which legume seeds were evaluated in pet food
processes and then fed to dogs. The results suggest that the
dehulled faba beans used in this study could be an effective
ingredient in dog foods. The ideal level appears to be just
below 20% of the diet. Whether they would have an impact
on the amino acid nutrition of the dog (e.g., taurine) that the
other legume seeds are being accused of would need to be
evaluated. But based on the evidence so far, it appears that
dehulled faba beans are a reasonable addition to complement our ingredient toolbox for pet diets. ■
