Note: It’s important to mention that tofu may have a slightly fermented smell due to its production process, which is different from a sour or rotten smell associated with spoilage.

By being aware of these signs, you can ensure that you only consume fresh and safe tofu in your meals.

Shelf Life of Unopened Tofu

When it comes to the shelf life of unopened tofu, there are a few factors to consider, including the type of tofu and how it is stored. Let’s take a closer look at the shelf life of different types of unopened tofu:

Shelf-Stable Tofu

  • Can last for 2-3 months

Now that we’ve discussed the shelf life of unopened tofu, let’s explore the proper storage methods for tofu in the next section.

Proper Storage of Tofu

Proper storage is key to maintaining the freshness and quality of tofu. Follow these guidelines to ensure your tofu stays delicious:

1. Refrigeration for Freshness

Refrigerated tofu should always be stored in the fridge, away from other strong-smelling foods. This helps prevent cross-contamination and preserves its delicate flavors. Tofu packaging typically comes with a water-filled plastic tub. To maintain moisture, keep the tofu in its original packaging and place it in a sealed container. If the packaging is damaged, transfer the tofu to an airtight container with fresh water.

2. Room Temperature for Shelf-Stable Tofu

Shelf-stable tofu, which is vacuum-sealed and doesn’t require refrigeration before opening, can be stored at room temperature. Find a cool and dry spot in your pantry or kitchen counter, away from direct sunlight. This type of tofu is a great pantry staple as it can last for months without refrigeration.

3. Protecting Tofu from Air Exposure

Tofu easily absorbs odors and can quickly dry out if not properly protected from air exposure. To keep it fresh, wrap opened tofu tightly in plastic wrap or place it in an airtight container. If storing tofu in a container, make sure to cover it with water to maintain its moisture and prevent drying. Regularly change the water every 1-2 days to ensure freshness.

4. Avoiding Extended Room Temperature Storage

Leaving tofu uncovered at room temperature for extended periods can create optimal conditions for bacterial growth and spoilage. It is important to promptly refrigerate tofu after opening and avoid leaving it at room temperature for longer than necessary.

By following these proper storage tips, you can prolong the shelf life of tofu and enjoy its delicate flavors in various dishes!

How Long Does Tofu Last in the Fridge?

If it’s unopened, tofu can last for the duration indicated on the package’s use-by date. Once opened, refrigerated tofu is generally good for 3 to 5 days if stored properly. Frequent opening of the refrigerator door can shorten the shelf life of tofu. Trust your senses and do not consume tofu that doesn’t look or smell right.

When it comes to storing tofu in the refrigerator, there are a few things to keep in mind to extend its shelf life. Firstly, always check the use-by date on the package and avoid using tofu that is past its expiration date. Secondly, ensure that the tofu is properly sealed or wrapped to prevent exposure to air and moisture. This will help slow down the spoiling process.

Additionally, be mindful of how often you open the refrigerator door. Every time the door is opened, the temperature inside fluctuates, which can negatively affect the tofu’s freshness. Try to minimize the number of times you open the refrigerator door and store tofu in a spot that is less likely to be exposed to warm air.

Lastly, trust your senses when it comes to determining the freshness of tofu. Give it a visual inspection and look for any signs of mold, discoloration, or an off-putting smell. If the tofu has an unusual texture or emits a sour or rotten odor, it’s best to discard it to avoid any risk of foodborne illness.

Fridge Storage Tips for Tofu:

  • Check the use-by date on the package.
  • Seal or wrap tofu properly to prevent exposure to air and moisture.
  • Minimize opening the refrigerator door to maintain a consistent temperature.
  • Store tofu in a cool spot in the refrigerator away from warm air.
  • Trust your senses and discard tofu that doesn’t look or smell right.

By following these storage tips and being mindful of the signs of spoilage, you can ensure that your tofu stays fresh and safe to eat.

Freezing Tofu

Tofu can be a versatile addition to many dishes, but it’s not always easy to use up an entire block before it reaches its expiration date. Thankfully, freezing tofu can help extend its shelf life and provide you with a convenient ingredient whenever you need it. Here’s what you need to know about freezing tofu:

1. Chop and drain:

Before freezing tofu, it’s important to remove excess water and prepare it for freezing. Start by cutting the tofu into smaller cubes or slices. This will not only make it easier to thaw and use later, but it will also allow the tofu to absorb flavors more effectively when cooked.

Once the tofu is cut into desired portions, it’s important to drain out as much moisture as possible. Excess moisture can lead to ice crystals forming, which can affect the texture of the tofu. To remove moisture, place the tofu on a clean kitchen towel or paper towels and gently press down to soak up the water.

3. Freezing:

Once the tofu is drained, it’s ready to be frozen. Place the tofu cubes or slices in a freezer-safe container or bag. For easier access, you can separate the portions by using parchment paper or plastic wrap between each piece. Make sure to seal the container or bag tightly to prevent freezer burn.

4. Shelf life:

Frozen tofu can last for 4-6 months in the freezer. However, it’s essential to note that the texture of the tofu may change upon thawing. Frozen tofu becomes more porous and can absorb marinades and sauces more effectively. This altered texture can be preferred in certain dishes, such as stir-fries and curries.


If you’re planning to use frozen tofu in a dish that requires firmer texture, such as grilling or frying, try thawing the tofu in the refrigerator for a few hours before cooking. Thawing it gradually will help retain a bit of its original texture.

Benefits of Freezing Tofu: Considerations:
  • Extends the shelf life of tofu
  • Convenient ingredient for future use
  • Enhances tofu’s ability to absorb flavors
  • Texture may change after thawing
  • Tofu may become more crumbly
  • Thawed tofu may be better suited for certain dishes

Shelf Life of Cooked Tofu

When it comes to cooked tofu, the shelf life is slightly longer compared to raw tofu. Cooked tofu can last for an additional 2-3 days in the refrigerator, allowing you to enjoy your tofu dishes for a little longer.

However, it’s important to note that cooked tofu does not freeze as well as raw tofu. Freezing cooked tofu may alter its texture, resulting in a softer or spongier consistency, which may not be suitable for all recipes. To determine if freezing cooked tofu is the right option for you, it is recommended to test a small batch before freezing a large quantity.

If you’re planning to store cooked tofu in the refrigerator, make sure to transfer the leftovers to an airtight container. This will help preserve its freshness and prevent it from absorbing odors from other foods in the fridge.

Remember, when it comes to food safety, always trust your senses. If cooked tofu starts to develop an off smell or unusual texture, it’s best to discard it to avoid any risk of foodborne illnesses.
