Soy Sauce

What Is Soy Sauce?

Soy sauce is a dark-colored, liquid sauce made by long fermentation of soybeans and mostly roasted wheat with salt and special yeast-microorganisms. It is one of the most fundamental condiments of East and Southeast Asian cuisines.

Fermentation gives it a salty, deep, rich "umami" flavor. It comes in light (thin, salty) and dark (intense, slightly sweet) varieties; classic types containing wheat carry gluten, while some varieties like tamari can be gluten-free.

Nutritional Values of Soy Sauce

Soy sauce is a low-calorie condiment, providing around 53 kcal per 100 ml, but it is very high in sodium; it also contains some protein. Those who need to limit salt intake should be careful; low-sodium varieties are also available.

How Should Soy Sauce Be Used?

Since soy sauce is very salty, it is used sparingly, usually tasted before additional salt is added to the dish. Those with a soy allergy or gluten sensitivity should check the ingredient label (wheat) carefully.

This information is general; soy sauce is a food, not a substitute for medical treatment.

How Is Soy Sauce Chosen?

Good soy sauce is naturally fermented, has a simple ingredient list, and is clear-dark colored. A light/dark, low-sodium, or gluten-free (tamari) variety is chosen based on purpose; the label is checked for content.

• Naturally fermented ones should be preferred
• Light/dark should be chosen based on purpose
• Sodium and gluten should be checked on the label

How Is Soy Sauce Stored?

Unopened soy sauce keeps for a long time in a cool, dark place; once opened, it should be stored in the fridge in a sealed container to better preserve its aroma. Its high salt content acts as a natural preservative, but flavor and color can change over time.

Using Soy Sauce in the Kitchen

Soy sauce is used most in stir-fries (wok), marinades, noodle-rice dishes, soups, dipping sauces, and meat-chicken dishes. Since it's a source of both salt and umami, it is added in moderation before any extra salt is used.

What Is the Difference Between Light and Dark Soy Sauce?

Light soy sauce is thinner, saltier, and adds flavor without much color; dark soy sauce is thicker, slightly sweeter, and colored. Both can be used together when both flavor and color are wanted.

Frequently Asked Questions

Does soy sauce contain gluten?

Classic soy sauce usually contains wheat and thus carries gluten; however gluten-free varieties like tamari exist. Those with gluten sensitivity should check the label.

Why is soy sauce so salty?

Since plenty of salt is used in fermentation, soy sauce's sodium content is naturally high; salt is part of both the flavor and the natural preservation. Low-sodium varieties can be preferred.

Does soy sauce go bad?

Thanks to its high salt content, it spoils slowly; still, its aroma and color can change over time once opened. Storing it in the fridge, sealed, preserves its quality.
