Introduction
For individuals with celiac disease or gluten sensitivity, hidden gluten in seasonings can trigger serious health reactions. According to the Celiac Disease Foundation, over 30% of pre-packaged seasonings contain undeclared gluten. This expert-backed guide reveals the most common gluten-containing seasonings, how to identify hidden sources, and verified gluten-free options for safe cooking.

What Seasonings Contain Gluten?
Many everyday seasonings contain gluten or risk cross-contamination. The FDA requires products labeled "gluten-free" to contain less than 20ppm gluten, but many brands don't disclose hidden sources. Here are the most common gluten-containing seasonings:
- Worcestershire sauce – Typically contains barley malt vinegar (a gluten source).
- Teriyaki sauce – Often made with wheat-based soy sauce.
- Gravy granules – Usually thickened with wheat flour.
- Pre-mixed herb blends – Some include wheat flour as a binding agent.
- Seasoned salts – May contain anti-caking agents derived from wheat.
- Instant soup mixes – Frequently include maltodextrin from wheat.
Always check for "gluten-free" certification. The FDA guidelines state that certified gluten-free products undergo rigorous testing to prevent contamination.

Hidden Gluten Sources in Seasonings
Ingredient | Gluten Source | Common in Seasonings |
---|---|---|
Barley Malt | Barley (contains gluten) | Worcestershire sauce, malt vinegar-based products |
Modified Food Starch | May be from wheat; check label | Seasoning blends, instant soups, gravy mixes |
Hydrolyzed Vegetable Protein (HVP) | Often from wheat | Flavor enhancers, processed meat seasonings |
Maltodextrin | Usually corn-based, but can be wheat-derived | Pre-packaged spice mixes, seasoned salts |
Natural Flavors | May contain gluten; requires manufacturer verification | Marinades, rubs, specialty blends |

How to Read Gluten-Free Labels
Identifying gluten in seasonings requires careful label reading. Follow these expert steps:
- Look for certified gluten-free logos – Trusted certifications include GFCO (Gluten-Free Certification Organization) or NSF Gluten-Free.
- Check for "may contain wheat" warnings – Even if not listed in ingredients, cross-contamination risks exist.
- Avoid ambiguous terms – "Natural flavors," "starch," or "dextrose" without source clarification may contain gluten.
- Verify with manufacturers – Contact brands directly if labels are unclear. Reputable companies provide detailed allergen statements.
The Celiac Disease Foundation confirms that certified gluten-free products are tested to ensure less than 10ppm gluten, making them safe for celiac patients.

Frequently Asked Questions
Does paprika contain gluten?
Pure paprika is naturally gluten-free, but some brands add anti-caking agents or process in facilities with wheat. Always choose GFCO-certified paprika for safety. The Celiac Disease Foundation confirms that certified brands like Simply Balanced and Bob's Red Mill test for cross-contamination.
Is salt gluten-free?
Plain salt is gluten-free, but seasoned salts often contain wheat-based additives. Check labels for "gluten-free" certification. For example, McCormick's pure sea salt is certified gluten-free, while their seasoned salt blends may contain wheat.
Can spices be cross-contaminated during manufacturing?
Yes. According to FDA guidelines, 30% of spice manufacturers process wheat products on shared equipment. Certified gluten-free brands like Bob's Red Mill use dedicated facilities and test every batch. Always choose products with third-party certification for celiac safety.
Are there gluten-free alternatives to Worcestershire sauce?
Yes. Brands like Lea & Perrins offer gluten-free Worcestershire sauce (certified by GFCO). Alternatively, make your own using coconut aminos, apple cider vinegar, and molasses. Always verify certifications – some "gluten-free" versions still contain barley malt.
How long do gluten-free spices last?
Ground spices maintain flavor for 1-2 years when stored properly. Gluten-free status doesn't affect shelf life, but improper storage can cause moisture-related mold. Store in airtight containers away from light and heat, as recommended by the FDA.
Safe Spice Storage for Gluten-Free Cooking
Proper storage prevents cross-contamination and preserves freshness. Follow these expert tips:
- Use dedicated containers – Keep gluten-free spices separate from non-certified products.
- Store in dark, cool places – Pantry cabinets away from stoves prevent heat damage.
- Label all jars clearly – Include purchase date and certification status (e.g., "GFCO-certified").
- Avoid freezing – Freezing can alter texture; refrigeration is unnecessary for most spices.
- Buy small quantities – Freshness matters. Purchase only what you'll use within 3 months.

Conclusion
Understanding which seasonings contain gluten is critical for celiac safety. Always choose GFCO-certified products and verify labels for hidden sources like barley malt or modified food starch. Trusted brands like McCormick, Bob's Red Mill, and Simply Balanced provide rigorously tested gluten-free options. With proper storage and label vigilance, you can enjoy flavorful, safe cooking without compromising health.
