Is Soy Sauce Vegetarian?

When it comes to vegetarianism, one might assume that soy sauce, a staple condiment in many Asian cuisines, would be a safe choice. However, the question of whether soy sauce is truly vegetarian is more complex than it seems. While soy sauce is primarily made from soybeans, which are plant-based, the production process often involves the use of animal-derived ingredients. In this article, we will delve into the various factors that determine the vegetarian status of soy sauce.

The Ingredients of Soy Sauce

Traditionally, soy sauce is made from four main ingredients: soybeans, wheat, salt, and water. The process begins with fermenting a mixture of soybeans and roasted wheat, which is then combined with salt and water. The mixture is left to ferment for several months, during which time it develops its distinct flavor and aroma.

Animal-Derived Ingredients in Soy Sauce

While the primary ingredients of soy sauce are plant-based, some variations of soy sauce may contain animal-derived ingredients. These ingredients are typically added to enhance the flavor or color of the sauce. Here are some examples:

  • Fish Sauce: Some soy sauces, particularly those from Southeast Asia, may include fish sauce as an ingredient. Fish sauce is made by fermenting fish with salt and is commonly used in Thai, Vietnamese, and Filipino cuisines.
  • Bonito Flakes: Bonito flakes, which are made from dried and fermented fish, are occasionally used to add a savory umami flavor to certain types of soy sauce.
  • Oyster Extract: In certain Chinese soy sauces, oyster extract is added to enhance the taste. Oyster sauce, a popular condiment in Chinese cooking, is also made from oyster extract.

Vegetarian and Vegan Soy Sauce

For individuals following a vegetarian or vegan diet, it is important to look for soy sauce that is specifically labeled as such. Fortunately, there are many brands that produce vegetarian and vegan-friendly soy sauce. These soy sauces are typically made without the use of animal-derived ingredients and are suitable for those following plant-based diets.

Here are some key points to consider when looking for vegetarian or vegan soy sauce:

  • Read the Label: Check the ingredients list carefully to ensure that no animal-derived ingredients are included.
  • Look for Certifications: Some soy sauce brands may have certifications such as “vegan” or “vegetarian” on their packaging, making it easier for consumers to identify suitable options.
  • Choose Tamari Sauce: Tamari sauce is a type of soy sauce that is traditionally made without wheat, making it gluten-free and often suitable for those with gluten sensitivities. Many tamari sauces are also vegetarian or vegan.


While soy sauce is primarily made from soybeans, the presence of animal-derived ingredients in certain variations makes it necessary for vegetarians and vegans to be cautious when choosing a soy sauce. By reading labels and looking for specific certifications, individuals can find vegetarian and vegan-friendly options that align with their dietary choices. Ultimately, the decision of whether soy sauce is vegetarian or not depends on the specific brand and ingredients used in its production.
