Tofu is a versatile and nutritious plant-based protein loved by many. But like all foods, it can go bad. Eating spoiled tofu can cause stomach cramps, nausea, or worse, so it’s important to know how to tell if your tofu is still fresh and safe to eat. Here’s a simple, easy-to-follow guide to help you spot the signs of bad tofu and keep your meals delicious and safe.
What Does Fresh Tofu Look and Smell Like?
Fresh tofu usually has a creamy white color and a smooth texture. It doesn’t have a strong smell-often it’s almost odorless or has a very mild, nutty scent. When stored properly in water and refrigerated, tofu can last for several days after opening.
Signs Your Tofu Has Gone Bad
1. Color Changes
One of the first things to check is the color. Fresh tofu is white or off-white. If you notice your tofu turning yellow, tan, or brown, that’s a warning sign it’s starting to spoil. Discoloration often means bacterial growth or that the tofu is deteriorating.
2. Smell It
Spoiled tofu has a distinct sour or rotten smell that’s hard to miss. If your tofu smells funky, like a sickly sweet or sour odor, it’s time to toss it out. Fresh tofu should not have a strong or unpleasant odor.
3. Texture Changes
Fresh tofu is smooth and slightly firm or soft depending on the type. If your tofu feels slimy, sticky, or clotted instead of smooth, it’s a sign of spoilage. Some spoiled tofu may also become hard or rubbery, which means it’s no longer good to eat.
4. Mold Growth
Visible mold is a clear sign that tofu is bad. Mold can appear as fuzzy patches or discoloration on the surface. If you see mold, don’t try to salvage the tofu-throw it away immediately.
5. Package Condition
If the tofu package is bloated or swollen, it means bacteria inside are releasing gas. This bloating is a strong indicator the tofu has spoiled and should not be consumed.
How Long Does Tofu Last?
– Unopened tofu in the fridge: Usually 3 to 5 days past the “sell by” or “use by” date if stored properly.
– Opened tofu in the fridge: Keep it submerged in fresh water in an airtight container and change the water daily. Use within 3 to 5 days.
– Unopened tofu in the pantry: Shelf-stable tofu can last 2 to 3 months unopened.
– Frozen tofu: Freezing extends shelf life for several months but changes texture, making it chewier and more porous-great for some recipes but not all.
Tips for Keeping Tofu Fresh Longer
– Store tofu in an airtight container with fresh water in the fridge.
– Change the water daily if you keep tofu stored for several days.
– Freeze tofu if you want to keep it longer, but expect texture changes.
– Always check the expiration date and buy fresh tofu regularly.
– Trust your senses-when in doubt, throw it out.
Tofu is a fantastic ingredient when fresh, but it’s crucial to recognize spoilage signs to avoid foodborne illness. Keep an eye on color, smell, texture, mold, and packaging to enjoy tofu safely.
