This article will dive into the details around Kewpie mayonnaise and gluten, including:
- What is Kewpie mayonnaise?

- Is cross-contamination a risk?
- What Kewpie mayo products are gluten-free?
- Is Kewpie mayo gluten-free in the United States?
- Verdict: Is Kewpie mayonnaise gluten-free?
Let’s start with some background on Kewpie mayo and go from there.
What is Kewpie Mayo?
Kewpie mayonnaise was created in 1925 by Japanese food company Q.P. Corporation. It was named after the Kewpie doll, which was popular at the time.
Kewpie mayo has a signature rich, eggy taste that comes from using only egg yolks rather than whole eggs. It also contains vinegar, salt, and vegetable oil.
Some key facts about Kewpie mayonnaise include:
- Made with egg yolks only for a richer flavor
- Higher fat content than regular mayonnaise at around 80%
- Thicker, creamier texture
- Slightly sweeter taste
- Bright yellow color
- Sold in squeeze bottles with a red cap
- Very popular in Japan and gained a cult following abroad
Kewpie operates factories in Japan, Thailand, Malaysia, and the United States to manufacture and distribute their mayonnaise globally.
The brand has grown exponentially over the decades to become the top-selling mayo in Japan. Their mayo packets are ubiquitous at restaurants across the country.
Internationally, Kewpie mayo is now sold at mainstream grocery stores and online retailers. Food enthusiasts praise its unique, egg-forward flavor profile.
Now that you know a bit about the origins and background of Kewpie mayonnaise, let’s look at the key question: does it contain gluten?
Does Kewpie Mayo Contain Gluten?
When reviewing the ingredients list for original Kewpie mayonnaise made in Japan, wheat or gluten are not listed.
The main ingredients include:
- Egg yolks
- Soybean oil
- Vinegar
- Salt
- Sugar
- Spices
Based on the ingredients list alone, Kewpie mayo would be considered gluten-free. None of the ingredients inherently contain gluten.
However, there are some important notes when it comes to gluten and mayonnaise:
- Mayonnaise is an emulsion of egg yolks, oil, and an acid like vinegar or lemon juice. Mustard is also sometimes added.
- Gluten grains like wheat, rye, and barley are not necessary ingredients in standard mayonnaise recipes.
- However, companies can add thickeners like wheat starch to get the desired mayonnaise texture.
- Flavorings like malt vinegar can also add trace gluten.
So while mayonnaise itself does not need to contain gluten as an ingredient, sometimes food manufacturers do add wheat-derived thickeners and flavorings.
With Kewpie mayo though, this does not appear to be the case based on the printed ingredients.
Kewpie Mayonnaise Ingredients
To summarize Kewpie’s mayonnaise ingredients:
- Egg yolks add rich flavor and act as the emulsifier
- Soybean oil is the fat/oil component
- Vinegar adds acidity
- Salt provides seasoning
- Sugar contributes sweetness
- Natural spices enhance the flavor
None of these simple ingredients raise any red flags for gluten.
The egg yolks, oil, and vinegar form the basic mayonnaise structure without needing stabilizers like wheat. And spices are naturally gluten-free.
So Kewpie mayonnaise has a very clean ingredients profile that appears to be wheat and gluten-free based on the list.
But what about cross-contamination during manufacturing? Let’s look into that next.
Is Cross-Contamination a Risk?
When evaluating whether packaged foods are truly gluten-free, cross-contamination is always a concern.
Cross-contamination happens when gluten-containing grains come into contact with the finished product during production or packaging. Even tiny amounts can cause issues for those sensitive.
Some potential ways cross-contamination could occur with mayonnaise include:
- Being made on shared equipment that also processes wheat-based foods
- Use of shared utensils or tools that touch gluten
- Airborne wheat particles in a shared facility
- Being packaged alongside wheat foods
So is cross-contamination something to worry about with Kewpie mayonnaise?
According to Kewpie’s FAQ page, their mayonnaise is made in dedicated factories that only manufacture mayonnaise. Other food products are not made on the same lines.
The FAQ states:
Kewpie Mayonnaise is manufactured in dedicated plants that only handle egg-based products to avoid any cross-contamination.
This approach by Kewpie seems to greatly reduce the risk of any gluten cross-contact during production.
Since mayonnaise facilities only handle egg-based ingredients and products, there is no opportunity for airborne wheat particles or shared equipment issues.
Packaging cross-contamination also seems very unlikely given Kewpie’s dedicated factory approach.
Based on available information from the company, cross-contamination does not appear to be a significant concern with Kewpie mayonnaise. Proper protocols seem in place.
So the ingredients and manufacturing methods indicate Kewpie mayo itself should be gluten-free. But are all products and sizes included?
What Kewpie Mayo Products Are Gluten-Free?
Kewpie manufactures a range of mayonnaise products beyond their classic mayo. This includes:
- Reduced fat mayonnaise
- Mayonnaise dressing
- Spicy mayonnaise
- Wasabi mayonnaise
- Roasted garlic mayonnaise
- Sesame mayonnaise
- Salad dressings
- Tartar sauce
According to Kewpie’s customer service, their statement about avoiding cross-contamination applies across all Kewpie mayonnaise products, not just the original.
This means standard sizes like 12 oz squeeze bottles, as well as flavored mayos and dressings, are all produced in the dedicated egg facility and free of gluten cross-contact.
When checking ingredients lists for Kewpie’s flavored mayos and dressings, wheat and gluten do not appear to be added either.
So you can feel confident that any Kewpie mayonnaise product, regardless of flavor or size, will be just as gluten-free as their popular original mayo.
Kewpie Products Made in Thailand
One note is that some Kewpie mayonnaise sold in the U.S. seems to be produced in Thailand, not Japan.
However, Kewpie has stated that all their mayonnaise production facilities worldwide follow strict protocols to prevent cross-contamination.
This applies to plants in Japan, Thailand, Malaysia, and the United States alike.
So Kewpie mayos made in Thailand can be considered just as gluten-free as those produced in Japan. The same ingredients and manufacturing processes are used globally.
Bottom line: all Kewpie mayonnaise products, regardless of flavor, size, or country of origin, look to be reliably gluten-free based on information from the company.
