Soy sauce is a popular condiment that is widely used in Asian cuisine. It is known for its rich umami flavor and is commonly used as a dipping sauce, marinade, or seasoning. However, for those following a vegan lifestyle, there may be some confusion about whether soy sauce is vegan or not. In this article, we will explore the ingredients used in soy sauce production and discuss whether it is suitable for vegans.

What is soy sauce?

Soy sauce is a traditional Asian condiment that has been used for centuries. It is made from fermented soybeans, roasted grains, water, and salt. The fermentation process gives soy sauce its distinct flavor and aroma. There are different types of soy sauce, including light soy sauce, dark soy sauce, and tamari.

Ingredients in soy sauce

Let’s take a closer look at the ingredients commonly used in soy sauce production:

  • Soybeans: The main ingredient in soy sauce is soybeans. These legumes are rich in protein and are fermented to create the base of the sauce.
  • Grains: Roasted grains such as wheat, barley, or rice are added to the soybeans. These grains provide additional flavor and help with the fermentation process.
  • Water: Water is used to hydrate the soybeans and grains and create the right consistency for fermentation.
  • Salt: Salt is a crucial ingredient in soy sauce production. It not only enhances the flavor but also acts as a preservative.

Is soy sauce vegan?

Based on the ingredients used in soy sauce production, it can be considered vegan. Soybeans, grains, water, and salt are all plant-based ingredients. However, there are a few factors to consider:

1. Fermentation process

During the fermentation process, microorganisms such as bacteria and yeast are involved in breaking down the proteins and carbohydrates in soybeans and grains. While these microorganisms are essential for the fermentation process, some vegans may have concerns about their use. However, it is important to note that the microorganisms are not present in the final product of soy sauce. They are filtered out, leaving behind the flavorful liquid.

2. Production methods

Some soy sauce brands may use additional ingredients or additives during the production process. These can include sweeteners, preservatives, or flavor enhancers. It is essential for vegans to read the ingredient labels carefully to ensure that no animal-derived ingredients are used.

3. Tamari soy sauce

Tamari is a type of soy sauce that is traditionally made without wheat. It is a suitable option for those with gluten intolerance or following a gluten-free diet. Tamari is typically made with soybeans, water, and salt, making it a vegan-friendly choice.


Soy sauce, made from fermented soybeans, grains, water, and salt, is generally considered vegan. However, it is important to check the ingredient labels to ensure that no animal-derived ingredients or additives are used. Tamari soy sauce, made without wheat, is a vegan-friendly alternative. So, vegans can enjoy the rich flavors of soy sauce in their favorite dishes without any concerns.
