Common Gluten Sources in Kimchi
While the base ingredients in traditional kimchi (napa cabbage, radish, garlic, and ginger) are naturally gluten-free, the seasonings and pastes often introduce gluten. This is particularly important for individuals with celiac disease or gluten sensitivity when purchasing kimchi or eating out.
Gochujang and Gluten
Gochujang is a significant source of hidden gluten. This fermented chili paste gives kimchi its color, spice, and savory notes. Traditional recipes often use barley malt powder, a gluten-containing grain, for fermentation.
- Barley Malt: Used in gochujang for flavor and fermentation, it makes the paste unsafe for those following a gluten-free diet.
- Gluten-Free Options: Many brands now offer certified gluten-free gochujang made with glutinous rice and fermented soybeans instead of barley.
Soy Sauce
Soy sauce is used to add salt and umami to kimchi. The gluten content of soy sauce can vary greatly.
- Traditional Soy Sauce: Often brewed with wheat and soybeans. Unless labeled "gluten-free," assume it contains wheat.
- Tamari: A Japanese soy sauce alternative, tamari, is often made with little to no wheat, but always check the label, as not all tamari is wheat-free.
Fish Sauce and Additives
Fish sauce adds saltiness, but some brands may include wheat-based additives.
- Fish Sauce: Most fish sauce is naturally gluten-free (made from fish and salt), but some may add preservatives or flavor enhancers that contain wheat protein. Always check the label.
Flour-Based Thickeners
Some kimchi recipes use a flour-based porridge to thicken the paste. While glutinous rice flour is gluten-free, some manufacturers may use wheat flour.
- "Glutinous" Rice Flour: It does not contain gluten. It provides a sticky texture. It is safe for those with celiac disease.
- Wheat Flour: If wheat flour thickens the kimchi paste, it is not gluten-free. Checking the ingredient list is essential.
How to Ensure Your Kimchi is Gluten-Free
If you have a gluten intolerance, you can enjoy kimchi safely with some care.
Check the Label
Always read the ingredient list for potential gluten sources like wheat or barley. Look for "gluten-free" labeling or a certified gluten-free symbol.
Choose Certified Gluten-Free Brands

- Jongga: Offers gluten-free options.
- Cleveland Kitchen: Provides gluten-free and plant-based kimchi.
- Wildbrine: Offers vegan and gluten-free fermented foods.
- Mother In Law's: Specializes in Korean-inspired, vegan, and gluten-free fermented foods.
Comparison Table: Gluten vs. Gluten-Free Kimchi
| Ingredient Category | Gluten-Containing Option | Gluten-Free Alternative |
|---|---|---|
| Chili Paste | Gochujang with barley malt | Certified GF Gochujang |

Prepare Kimchi at Home
Making kimchi at home ensures control over ingredients. Recipes are available for gluten-free kimchi, using safe ingredients like tamari, gluten-free gochujang, and glutinous rice flour.
Consider Cross-Contamination
Even if a kimchi recipe is gluten-free, there's a risk of cross-contamination, especially in restaurants or facilities that also process gluten products. Always inquire about ingredients and production methods when dining out to ensure safety.
The Fermentation Process and Gluten
The fermentation process does not eliminate gluten. Lactic acid bacteria do not break down gluten proteins. The gluten content depends on the ingredients used before and during fermentation.
Conclusion: Safe Kimchi Choices
Kimchi requires attention for those on a gluten-free diet. Kimchi is not inherently gluten-free; its safety depends on the ingredients. Understanding the risks in gochujang and soy sauce is important. By checking labels or making your own, you can enjoy kimchi. Always assume commercial kimchi contains gluten unless labeled gluten-free. For certainty, preparing it yourself with certified gluten-free ingredients is best.
