When most people buy a seasoning blend, they expect the jar to be filled with ingredients that contribute flavor to their food.
After all, if you're paying for a Cajun seasoning, BBQ rub, taco seasoning, or herb blend, you probably want the herbs, spices, and seasonings that create the taste you enjoy.
But not every ingredient found in a seasoning blend is necessarily there to add flavor.
Some products contain ingredients commonly referred to as fillers.
At The French Longhorn, we believe consumers deserve to understand what they're buying and why every ingredient is included. Let's take a closer look at what fillers are, why they're used, and how to identify them on a seasoning label.
What Is a Filler?
A filler is generally an ingredient that is added primarily to increase volume, improve texture, support manufacturing processes, or reduce production costs rather than directly contribute significant flavor.
Not all fillers are harmful or undesirable. In many cases, they serve practical purposes within a product formulation.
However, consumers who value ingredient transparency often want to know which ingredients are there for flavor and which are there for other reasons.
Understanding that distinction can help shoppers make more informed purchasing decisions.

Why Are Fillers Used?
Manufacturers may use fillers for a variety of reasons, including:
- Increasing product volume
- Improving consistency
- Supporting mixing and processing
- Creating a particular texture
- Managing production costs
- Enhancing flowability
Depending on the product, a filler may help create a more uniform appearance or improve manufacturing efficiency.
The key question many consumers ask is:
"How much of what I'm buying actually contributes to flavor?"
Common Fillers Found in Seasoning Blends
Several ingredients are sometimes used as fillers or bulking agents in food products and seasoning blends.
Examples may include:
- Maltodextrin
- Modified food starch
- Rice flour
- Corn flour
- Wheat-based ingredients
- Certain starches and carriers
These ingredients can serve various technical functions depending on the product and formulation.
While they may have legitimate uses, they generally do not provide the same flavor impact as herbs, spices, garlic, onion, peppers, or other seasoning ingredients.
Many of these ingredients appear alongside other additives discussed in Common Hidden Ingredients Found in Store-Bought Seasonings.
Fillers vs. Flavor Ingredients
One of the easiest ways to evaluate a seasoning blend is to ask:
Which ingredients are creating the flavor?
Examples of flavor ingredients include:
- Garlic
- Onion
- Paprika
- Black pepper
- Cumin
- Chili peppers
- Oregano
- Thyme
- Rosemary
- Parsley
These ingredients directly contribute aroma, taste, color, and character.
By contrast, fillers typically serve a functional role rather than a flavor role.
Understanding the difference can help consumers compare products more effectively.
