is kewpie gluten free

Many people on gluten-free diets often wonder if Kewpie, a popular brand of Japanese mayonnaise, is suitable for their dietary needs. In this article, we will explore whether Kewpie is gluten-free or not, providing you with all the information you need about this condiment.

What is Gluten?

Before diving into the gluten content of Kewpie mayonnaise, let’s first understand what gluten is. Gluten is a group of proteins commonly found in wheat, barley, and rye. These proteins can cause adverse reactions in individuals with gluten intolerance, celiac disease, or wheat allergies.

Ingredients of Kewpie Mayonnaise

Examining the ingredients listed on the packaging of Kewpie mayonnaise is a crucial step in determining its gluten content. Let’s take a closer look at the ingredients commonly found in Kewpie mayonnaise:

  • Soybean oil
  • Egg yolk
  • Distilled vinegar
  • Water
  • Mustard seed
  • Salt
  • Sugar

As we can see from the list above, none of the ingredients contain gluten. Therefore, Kewpie mayonnaise can be considered gluten-free.

Manufacturing Process

The manufacturing process of Kewpie mayonnaise is also important to consider. Cross-contamination can occur during production, where gluten-containing ingredients are processed in the same facility. While the ingredients themselves may not contain gluten, cross-contamination can render the final product unsuitable for individuals with gluten sensitivities.

However, Kewpie takes measures to prevent cross-contamination and maintains strict manufacturing standards. Their production facilities have separate lines to prevent gluten from mixing with gluten-free products. Therefore, Kewpie mayonnaise can be safely consumed by those following a gluten-free diet.

Gluten-free Certifications

To provide further assurance to consumers, some manufacturers obtain gluten-free certifications for their products. These certifications indicate that the product has been tested and confirmed to meet strict gluten-free standards. Unfortunately, Kewpie mayonnaise does not currently hold any specific gluten-free certifications.

Recommendations for Individuals with Gluten Sensitivities

If you have gluten sensitivities, it is always a good idea to read product labels and consult with healthcare professionals to ensure it aligns with your dietary needs. While Kewpie mayonnaise is considered gluten-free based on its ingredients and manufacturing processes, individual sensitivities may vary. It is best to listen to your body and make informed decisions accordingly.


In conclusion, Kewpie mayonnaise is gluten-free. Its ingredients do not contain gluten, and the manufacturing process includes measures to prevent cross-contamination. While it does not hold specific gluten-free certifications, it remains a suitable option for individuals with gluten sensitivities, celiac disease, or wheat allergies. As with any dietary restrictions, it is crucial to be informed and consult professionals to ensure the best choices for your specific needs.
