Limited Ingredient Dog Food: Citrus Fiber to the Rescue
Limited ingredient dog food is tailored to consumers seeking clean label pet foods. However, formulating up to 10 pet ingredients poses formulation challenges affecting the label, texture and quality. Citri-Fi® citrus fiber, with water binding and emulsification properties, is a natural pet food ingredient with thickening and stabilizing power. At low usage levels (<1%), citrus fiber can improve the label, stability, and texture of a variety of dog foods.
Raise your hand if you have caught your family dog lick road kill or drag a lifeless squirrel to your feet. Any time these distasteful moments occur, I remind myself, this is what separates human from canine. Yes, this is coming from someone who dresses her dog in raincoats or books her fur baby a spa at the local groomer. Despite their “call of the wild” behaviors, we still love our dogs. And we would give the shirt off our back to make sure our dogs are happy and healthy which includes feeding them the best dog food and dog treats. Today, healthy dog food means natural, sustainable and personalized. This clean diet trend gave rise to limited ingredient dog food.
What is a Limited Ingredient Dog Food?
This type of formulation is specialized created using a minimal number of simple pet food ingredients. Diets like these reduces a dog’s exposure to potential allergens. Formulas typically contain four to 10 main pet ingredients. For instance, the limited recipes include one single animal protein and one single carbohydrate. Because some traditional animal protein sources tend to be allergenic, pet food developers incorporate novel proteins. Examples include kangaroo or bison. These are proteins typically not consumed by dogs previously. Moreover, these limited ingredient dog recipes do not contain common fillers like corn, wheat, soy, dairy, or eggs.
Creating a limited ingredient dog food comes with challenges. Some of these issues affect the labeling, texture and quality over shelf life. Since these pet products typically use clean and non-allergenic food ingredients, there are very few alternatives available.
Clean Label Dog Food
Limited ingredient dog foods tend to veer away from stabilizers like food gums and starches. Without these pet food binders, foods lack viscosity and/or leach water over shelf-life. Many pet food types need pet food thickeners and pet food texture enhancers to maintain quality. At the same time, these pet ingredients need to be multi-functional to meet the limited ingredient recipe requirements.
Citri-Fi citrus fiber, which is a byproduct of the citrus juicing process, provides the water holding and emulsification properties needed by pet foods like semi-moist, canned or wet and fresh raw pet food. Depending on the usage level, citrus fiber adds thickness while improving the stability of the dog food. Labeling options include citrus fiber, dried citrus pulp or citrus flour which resonate well in the natural markets.
Alternative Pet Food Binders and Dog Food Emulsifiers
Since these limited ingredient dog foods shy away from allergens, traditional binders like wheat gluten is not an option. Without binders, foods like kibble break easily into fines especially during shipping and handling. Very few non-allergenic binders exist on the market. Citri-Fi citrus fiber is a non-allergenic binder solution. At low usage levels (<1%), this citrus fiber has shown to strengthen biscuits and also injection-molded dog bones minimizing crumbling and breakage.
In canned or wet dog foods like pâté or stews, common thickeners are used to prevent fat and protein separation. Without the use of starches or food gums like carrageenan, water and fat purge out. Citri-Fi citrus fiber binds the water and emulsifies to improve limited ingredient dog foods. For instance, the citrus fiber reinforces the firm pet loaf shape. And this natural pet ingredient creates a stable flowable gravy.
Limited Ingredient Dog Foods – High Meat Usage or Grain-free
Some formulations use a high level of meat. As a result, these dog foods contain more fat and moisture which may overtax food starch’s binding capabilities. For example, kibble becomes greasy and crumbly when fat purges from the matrix. Pet ingredients, like citrus fiber, may aid in binding the extra fat and water from high protein pet recipes. At the same time, citrus fiber can be used along with starches to improve the texture, stability and nutrition of a variety of high meat formulations.
Another dog food type involves removing grain from the pet recipe. Grain-free pet foods need specialized binders to reinforce the protein structure of limited ingredient pet foods. Citri-Fi citrus fiber, at low usage levels (<1%), can aid in binding water and emulsifying fats to improve the pet food texture. This pet food emulsifier uses its native intact pectin to bind the water and fat.
The Future of Limited Ingredient Foods
Currently, formulators manually cobble together recipes satisfying the four to 10 ingredient scope. However, in the future, creating pet food recipes will require pet food developers to consider other factors. For example, pet food companies are investing heavily in new technologies focusing on personalized dog nutrition. Latest innovations emerging include microbiome research, 3D printing and AI driven weight screening.
Eco-friendly and upcycling trends are driving pet food formulators to seek out sustainable proteins. New technologies unfolding in this arena are creating new hypoallergenic alternatives. Development strategies use precision fermentation, cultivated (lab grown) meats and insect protein to create a better limited ingredient dog food.
In the end, consumers still demand clean and transparent foods. This humanization trend continues to focus on ingredient traceability, upcycled pet ingredients and minimal processing. Citri-Fi, an upcycled citrus fiber, checks all those boxes. This citrus fiber’s efficient dual functionality should be in all pet food formulator tool boxes. It is ideal for pet foods and pet treats. Citri-Fi is non-allergenic, non-GMO project certified and has no e-number. The Citri-Fi 400 series is USDA and Europe organic certified.
