What is soy sauce?

Soy sauce is a liquid condiment from soybeans, wheat, salt, and water. It is used as a dipping sauce, marinade, or seasoning in East Asian cuisines.

The earliest recorded use of soy sauce dates back to the 3rd century CE in China. During the Tang dynasty, soy sauce was called Jiang you and was used as a table condiment. However, it wasn’t until the Song dynasty that soy sauce began to be used as a cooking ingredient.

Soy sauce is made by fermenting soybeans and wheat with salt and water. The fermentation process can take anywhere from several months to a year. After fermentation, the soy sauce is filtered and bottled.

Soy sauce is a popular ingredient in many East Asian dishes, such as stir-fries, marinated meats, and soup. It can also be used as a dipping sauce or to flavor other dishes.

Soy Sauce Ingredients:

  • Soybeans
  • Wheat
  • Salt
  • Water

Is There Lactic Acid In Soy Sauce?

Lactic acid is a sour-tasting compound in many foods, including soy sauce. It is produced by the fermentation of carbohydrates and is often used as a preservative or flavor enhancer. While lactic acid is not derived from animals, it may be made using animal-derived enzymes. Therefore, some vegans may consider it as non-vegan. (I know some vegans who ignore this).

Therefore, it is important to check the labels of soy sauce products to determine if they are vegan.

Ways to Use Soy Sauce in Vegan Dishes:

Soy sauce can be used in various vegan dishes to add flavor. For example, it can be used as a marinade for tofu or tempeh, added to stir-fries or soups, or used as a dipping sauce.

Some soy sauce products are also gluten-free, ideal for those following a gluten-free, vegan diet.

When choosing a soy sauce, select one labeled “vegan” or “vegetarian” to ensure that it does not contain any animal-derived ingredients.
