Soy sauce is a staple condiment at home because it adds flavor to any meal. It is also the perfect seasoning for almost all Asian dishes and for savory sauces.
But for those on a strict diet, one always asks, is soy sauce gluten-free? The quick answer to that is no because it is a by-product of wheat and soya which are known as glutinous.
But there are ways to make it gluten-free and there are brands that are already gluten-free so if you are curious about these, this post is for you.
What is soy sauce?
Soy sauce and the use of it is traced back to 3,000 years ago in China. It is made from fermenting wheat and soybeans with mold or yeast. While it originated in China, the name soy is derived from the Japanese word ‘shoyu’. With the wonders it does to food, it gained culinary traction easily.
It first spread to Asian countries such as Japan, Indonesia, Korea, and the rest of Southeast Asia. In the 1600s, soy sauce was brought to Europe through the infamous Dutch-Japanese trade. Today, you can find subtle regional differences in the taste and texture of soy sauce as it has been incorporated in various cultures.
What is soy sauce made out of?
There are four basic ingredients used in making soy sauce: wheat, soybeans, salt, and fermenting agent (mold or yeast). This is done by first soaking the soybeans in water and then roasting the wheat. After that, the soybeans and the wheat are mixed in a culturing mold and are left there to be cultured for up to a week.
After this, salt and water are added to the mixture and then placed in a fermentation tank. The new mixture is left there for eight months or more than a year. When it is done, the mixture is squeezed using a cloth and then the liquid is bottled.
Depending on the brand and variety, you would see variations in your soy sauce. Japan is producing more varieties of soy sauce than anywhere in the world. The soy sauce they produce includes dark soy sauce, light soy sauce, tamari, shiro, and saishikomi.
