Walk down the seasoning aisle of almost any grocery store and you'll find countless products with long ingredient lists. Some include preservatives, some don't, and many consumers are left wondering: Do dried spices and seasonings actually need preservatives?
The short answer is: not always.
In fact, many dried herbs and spices have been valued for centuries because they naturally store well when kept in the right conditions. While preservatives can serve a purpose in certain food products, they are not always necessary in seasoning blends.
At The French Longhorn, we believe understanding what goes into your food is just as important as understanding how it tastes. Let's explore why preservatives are sometimes used, when they're needed, and why we've chosen a different approach.
What Are Preservatives?
Preservatives are ingredients added to foods to help maintain quality and extend shelf life.
Their purpose is typically to:
- Slow spoilage
- Reduce microbial growth
- Protect flavor and color
- Extend storage time
Preservatives are commonly found in products that contain significant amounts of moisture, such as sauces, dressings, beverages, baked goods, and prepared foods.
But dried seasonings are different.

Why Moisture Matters
Most food spoilage occurs when moisture creates an environment where microorganisms can grow.
Fresh produce, dairy products, and cooked foods contain significant water content, making preservation more challenging.
Dried spices and herbs, on the other hand, contain very little moisture.
Because they are naturally low in water content, many spices are already relatively stable when stored properly.
This is one reason spices have played such an important role throughout culinary history. Long before refrigeration existed, people relied on dried herbs and spices because they could be stored for extended periods.

Why Some Seasoning Blends Contain Preservatives
Not all seasoning blends are created equal.
Some manufacturers add preservatives to help maintain consistency over long distribution periods or to support products containing ingredients that may be more sensitive to environmental conditions.
Preservatives may also be used when manufacturers want to maximize shelf life under a wide variety of storage conditions.
For large-scale production and distribution, these considerations can become important.
However, many seasoning blends can achieve excellent shelf life through proper ingredient selection, low moisture content, quality packaging, and proper storage practices.
Do Preservatives Improve Flavor?
Not necessarily.
Preservatives are primarily used for stability, not taste.
The flavors people enjoy in a seasoning blend typically come from ingredients such as:
- Garlic
- Onion
- Paprika
- Black pepper
- Chili peppers
- Herbs
- Citrus powders
- Other spices and seasonings
The quality of these ingredients is what ultimately creates the flavor experience.
That's why we focus on selecting high-quality herbs and spices rather than relying on additional ingredients that do not contribute to taste.

Why We Choose Not to Use Preservatives
At The French Longhorn, we believe seasoning blends should be as straightforward as possible.
Our approach is simple: If an ingredient isn't helping create flavor, we carefully evaluate whether it belongs in the blend.
Rather than relying on preservatives, we focus on selecting quality ingredients, using proper packaging, and recommending appropriate storage conditions so our customers get the best possible product from the moment they open it.
When you choose our seasonings, you're choosing a blend that contains only what matters: pure, flavorful spices and herbs.
