July 22, 2023

Identifying whether a product is vegan can often be a challenge, and Kewpie Mayo is no exception. 

This difficulty arises due to manufacturers often being elusive about the true nature and source of their ingredients — late-stage capitalism and all that.

This article is designed to clear up any confusion, helping to support you in your vegan lifestyle by unraveling the truth about this popular condiment.

Is Kewpie Mayo Vegan?

No, traditional Kewpie Mayo is not vegan. The main reasons behind this are the inclusion of egg yolk and other animal-based ingredients in its recipe.

Egg yolks, the primary non-vegan ingredient, play a significant role in creating the signature creamy texture and taste that distinguishes Kewpie Mayo from other mayonnaise types. While it might enhance the flavor and consistency, the use of egg yolks poses a serious problem for those committed to a vegan lifestyle, or those who simply enjoy vegan mayonnaise.

Is Kewpie Mayo Cruelty-Free?

Given the use of egg yolks in the production of Kewpie Mayo, it can’t be considered cruelty-free. Egg production often involves practices that cause harm to hens, which directly contradicts the principles of a cruelty-free lifestyle.

What Is Kewpie Mayo Made Of?

Kewpie Mayo, often hailed for its unique, tangy flavor, is composed of several ingredients that contribute to its distinct taste. Here’s a rundown of the ingredients in the original Kewpie Mayo:

Distilled vinegar is another primary ingredient in Kewpie Mayo. This vinegar is often derived from grains or fruit, making it a vegan-friendly addition.
