1Understanding Soy Sauce
1.1. What is soy sauce?
Soy sauce, also known as xì dầu (from the Cantonese pronunciation), is a dark-colored liquid with a moderate salty taste used to marinate food, as a dipping sauce, or as a seasoning for everyday meals. It’s primarily produced from soybeans through fermentation and aging over a long period.

1.2. How is soy sauce made?
To create delicious and rich soy sauce, manufacturers use 100% naturally fermented pure soybeans. This method not only preserves the exquisite taste of soybeans but is also safe for consumers’ health.
There are six steps in soy sauce production. It begins with selecting ingredients, sterilizing soybeans and wheat, then fermenting the mixture naturally for 3-6 months. Afterward, it’s pasteurized and blended with other ingredients to create standard, naturally rich soy sauce.

2Is soy sauce the same as oyster sauce?
Soy sauce is not oyster sauce. Oyster sauce is a sauce made by processing oysters. The most common oyster sauce today is a dark brown, thick sauce made from sugar, salt, water, and cornstarch, flavored with oyster extract.
Meanwhile, soy sauce is made from naturally fermented pure soybeans, and it’s thinner, not as thick as oyster sauce. Therefore, in terms of ingredients and appearance, these two seasonings are completely different.

3What is the difference between xì dầu and soy sauce?
Soy sauce and xì dầu are essentially the same; the name varies by region. Both are dipping sauces made from soybeans, roasted grains, salt, and water through fermentation or hydrolysis.
Xì dầu is simply a Chinese name derived from the Cantonese pronunciation “see-yau.” However, in Southern Vietnam, it’s often called nước tương (literally “soy sauce”) because it’s made from đậu tương (soybeans).
4Differences between types of soy sauce
4.1. Differences in ingredients
Currently, soy sauce is extracted from various ingredients such as soybeans, peanuts, etc. They are pressed or fermented to obtain oil, which can create different aromas and flavors.
4.2. Differences in production process
Soy sauce using peanut oil cake as the main ingredient is made through acid hydrolysis.
Soy sauce made from soybeans as the main ingredient is fermented and takes 3-4 months to produce the final product.

5.2. Use to marinate ingredients
Many people use soy sauce to marinate ingredients like meat, shrimp, and many others. This not only helps the ingredients absorb the flavor evenly but also brings an attractive aroma to the dish.
However, not all ingredients or dishes can be marinated with soy sauce. Because soy sauce has a slightly acidic taste when cooked, it is only suitable for marinating grilled, steamed, and some stir-fried dishes.
