Understanding Tofu and Its Shelf Life
Tofu, also known as bean curd, is made from soybeans and has been a dietary staple in many cultures for centuries. Its shelf life varies depending on the type of tofu (silken, firm, extra-firm) and how it is packaged and stored. Generally, tofu is sold in two main forms: refrigerated and shelf-stable.
- Refrigerated Tofu: Typically sold in water-filled containers, this type of tofu must be kept in the fridge and usually has a shorter shelf life.
- Shelf-Stable Tofu: Sold in vacuum-sealed packages, this tofu can be stored in the pantry until opened, after which it should be refrigerated.
How Long Does Tofu Last in the Fridge?
Unopened Tofu:
- Refrigerated tofu, when unopened, can last for 3 to 5 days past its expiration date if kept in the fridge.
- Shelf-stable tofu, once opened, should be transferred to a water-filled container and refrigerated, where it will last for 3 to 5 days.
Opened Tofu:
- Once you open a package of tofu, it should be consumed within 3 to 5 days for optimal freshness.
- It's essential to store it in fresh water and change the water daily to extend its shelf life.
Signs That Tofu Has Gone Bad
Tofu can go bad, and it's important to know the signs so you can avoid consuming spoiled tofu. Here’s what to look for:
- Sour Smell: Fresh tofu has a mild, neutral smell. If it starts to smell sour or unpleasant, it’s a sign that it’s no longer safe to eat.
- Color Change: Tofu should be white or off-white. If it develops a yellowish hue or dark spots, it's likely gone bad.
- Texture Changes: Fresh tofu is firm and smooth. If it feels slimy or mushy, it’s time to discard it.
- Taste: If you’re unsure, taste a small piece. If it has a sour or bitter taste, it’s best to throw it away. What should tofu taste like? Learn more in our related blog.
Best Practices for Storing Tofu
To keep tofu fresh for as long as possible, follow these storage tips:
- Refrigerate Immediately: Store tofu in the fridge as soon as you bring it home. If it's unopened, keep it in its original packaging.
- Change Water Daily: For opened tofu, place it in a container filled with water, and be sure to change the water every day. This helps maintain freshness and prevents bacteria growth.
- Use an Airtight Container: If you don’t have a container with water, store tofu in an airtight container to reduce exposure to air, which can cause it to spoil faster.
Can You Freeze Tofu?
Yes, you can freeze tofu! Freezing tofu can change its texture, making it chewier and more sponge-like, which some people prefer for certain dishes. Here’s how to freeze tofu:
- Drain the Tofu: Remove as much water as possible by pressing the tofu.
- Cut into Pieces: You can freeze tofu in whole blocks or cut it into smaller pieces.
- Freeze in an Airtight Container: Place the tofu in an airtight container or freezer bag. It can last in the freezer for up to 3 months.
- Thawing: When you’re ready to use it, thaw the tofu in the fridge overnight. Remember that frozen tofu absorbs sauces and marinades better, making it ideal for flavorful dishes.
Tips for Using Leftover Tofu
Leftover tofu can be used in a variety of dishes. Here’s how to make the most of it:
- Stir-Fries: Tofu’s firm texture makes it a perfect addition to stir-fries.
- Smoothies: Blend silken tofu into smoothies for a protein boost.
- Soups: Tofu adds texture and nutrition to soups and stews.
- Salads: Add chilled tofu cubes to salads for a filling protein.
