Do you like tofu? Tofu has many loyal fans around the world, but did you know these interesting facts about tofu? This article will answer 15 of the most frequently asked questions about tofu in a lighthearted, fun, and practical way. Let's take a look!
What is tofu?
Tofu is a plant-based protein made from soybeans. The easiest way to think about it is "soy milk turned into a solid," kind of like how milk becomes cheese. Once soy milk is coagulated and pressed, it becomes a soft, neutral-flavored block that can be cooked in endless ways.
What is tofu made of?
Tofu is made from soybeans, and it contains only a few ingredients: soybeans, water, and a coagulant (often nigari, gypsum, or lemon juice). That's it. No mystery ingredients, no weird additives, just plants and minerals doing their thing.
How is tofu made?
Tofu is made by turning soy milk into solid curds, similar to how cheese is made from dairy milk. Here's the process in a clear, simple way:
Soaking the Soybeans: Dried soybeans are washed and soaked in water for several hours (usually 8–12) until they become soft and plump.
Grinding and Cooking: The softened beans are blended with water to create a slurry.
This mixture is then cooked to improve flavor, remove raw beany taste, and make the proteins easier to extract.
Filtering to Make Soy Milk: The cooked slurry is filtered through cloth to separate the soy milk from the okara (soy pulp). Only the soy milk is used for tofu; okara can be used in other recipes.
Coagulating: A coagulant is added to hot soy milk to make it form curds.
- Common coagulants include:
- Nigari (magnesium chloride) – most traditional
- Gypsum (calcium sulfate)
- Lemon juice or vinegar (more for homemade tofu)
These coagulate the protein and fat, causing the soy milk to separate into curds and whey.
Forming and Pressing the Tofu: The curds are scooped into a mold lined with cheesecloth.
They are then pressed to remove excess water.
- Light pressing → soft/silken tofu
- Medium pressing → firm tofu
- Heavy pressing → extra-firm tofu
The more it's pressed, the denser the final tofu.
Cooling and Cutting: The pressed tofu block is removed from the mold, cooled in water, and cut into pieces. It's now ready to package or cook.
Is tofu healthy?
Yep, tofu is one of the healthiest and most nutrient-dense foods you can eat. It's high in protein, low in calories, rich in iron, contains calcium, and has heart-friendly fats. It also offers plant compounds called isoflavones, which may support bone health and cardiovascular health. If you want a clean, protein-rich food that works in almost any diet, tofu hits the mark.
Who invented tofu?
The origins of tofu trace back to ancient China, and while its exact inventor remains uncertain, tradition most often credits Liu An, a prince of the Han Dynasty (164–122 BCE), with its creation.
According to historical accounts, Liu An experimented with soybeans and discovered how to coagulate soy milk, producing an early form of tofu. However, many scholars believe tofu may have been invented accidentally—perhaps when soy milk mixed with mineral-rich seawater or impure salt—or that it evolved gradually through influences from nearby cultures with cheese-making traditions. What historians do agree on is that tofu emerged in China around the 2nd to 1st century BCE before spreading to Japan and the rest of Asia centuries later. Today, tofu's long history continues to shape its role as a nutritious and versatile staple across global cuisines.
How to cook tofu?
The real magic of tofu lies in how it transforms depending on how you cook it. You can pan-fry it, air-fry it, bake it, marinate it, scramble it, grill it, toss it into soups, or blend it into smoothies and sauces. Tofu absorbs flavor like a sponge, so strong seasoning, marinades, and sauces are your best friends. For crispy tofu, press it first, then toss in cornstarch and fry or bake until golden.
Mapo tofu is the most popular tofu dish.
How does the tofu taste?
Here's the secret: tofu itself is almost flavorless. But that's the whole point. Think of it like rice or pasta — neutral on its own, but amazing once you season it right. Its taste depends entirely on what you cook it with. Silken tofu is smooth and custardy, while firm tofu is chewy and hearty, making it ideal for savory dishes.
Can tofu be eaten raw?
Yes, you can eat tofu straight from the package without cooking it. Just drain it, give it a rinse, and pat it dry. Silken tofu is especially great in smoothies, desserts, dips, and cold dishes like tofu salad. Just make sure it's stored properly and hasn't expired.
Can dogs eat tofu?
Dogs can eat tofu, but only in moderation. Tofu isn't toxic to dogs, but it shouldn't be a primary protein source since dogs need animal-based amino acids. A little piece now and then is fine — just make sure it's plain, unseasoned, and not fried.
What are the nutritional components of tofu?
Tofu packs a punch for such a simple food. It typically includes high-quality plant protein, iron, calcium (especially if made with calcium sulfate), magnesium, potassium, and healthy fats. It's also cholesterol-free and low in saturated fat, making it a heart-friendly choice.
Is tofu gluten free?
Yes, plain tofu is naturally gluten-free. The only time gluten becomes an issue is with flavored tofu, pre-marinated tofu, or tofu products that use wheat-based ingredients. If you're gluten-sensitive, stick to simple, unseasoned tofu and check labels for hidden additives.
Does tofu go bad?
Tofu definitely goes bad, and when it does, you'll know. Signs include sour smell, off-color, slimy texture, or a swollen package. Once opened, tofu lasts about 3–5 days in the fridge. If you want it to last longer, change the soaking water daily.
Is fermented tofu safe to eat?
Fermented tofu — also known as "stinky tofu" or "fermented bean curd" — is totally safe and a traditional food in many Asian cuisines. It's salty, funky, bold, and used more like cheese or a seasoning paste. If the smell shocks you at first, don't panic — that's part of the charm.
Can you freeze tofu?
Absolutely. Freezing tofu actually improves its texture, making it chewier and more "meaty." Once thawed, it becomes more absorbent, perfect for marinades and sauces. Just know that silken tofu doesn't freeze as well as firm varieties.
