In this guide, we will explore the question: does tofu expire in the fridge? We will discuss the shelf life of tofu, how to store it correctly, and signs of tofu spoilage.

Understanding Tofu Shelf Life

Tofu is a perishable product made from soybeans, so it does have a limited shelf life. The shelf life of tofu can vary depending on factors such as the type of tofu, how it is packaged, and how it is stored. Here are some general guidelines for the shelf life of different types of tofu:

Types of Tofu and Shelf Life

1. Fresh Tofu:

   • Typically found in the refrigerated section of grocery stores.
   • Shelf life: 3-5 days if unopened, 3-5 days after opening if stored in water and changed daily.

2. Silken Tofu:

   • Soft and delicate tofu often used in soups and desserts.
   • Shelf life: 3-5 days if unopened, 3-5 days after opening if stored in water and changed daily.

3. Firm Tofu:

   • Denser tofu that holds its shape well in stir-fries and grilled dishes.
   • Shelf life: 3-5 days if unopened, 3-5 days after opening if stored in water and changed daily.

Factors Affecting Tofu Shelf Life

1. Packaging:
   • Vacuum-sealed tofu tends to have a longer shelf life compared to tofu in water packs.
2. Temperature:
   • Tofu should be kept refrigerated at all times to slow down bacterial growth.
3. Contamination:
   • Cross-contamination with other foods can shorten the shelf life of tofu.
4. Storage:
   • Proper storage is key to extending the shelf life of tofu.

How to Properly Store Tofu in the Fridge

To maximize the shelf life of your tofu and ensure its freshness, follow these storage tips:

1. Unopened Tofu

• Keep unopened tofu in its original packaging.
• Check the expiration date before purchasing.
• Store it in the refrigerator at a temperature of 35-40°F (1.6-4.4°C).

2. Opened Tofu

• If you've opened the tofu but have leftovers, transfer it to an airtight container and cover it with water.
• Change the water daily to keep the tofu fresh.
• Consume opened tofu within 3-5 days for the best quality.

3. Freezing Tofu

• If you're not going to consume the tofu within a few days, consider freezing it.
• Drain the tofu, wrap it in plastic wrap or place it in a freezer bag, and freeze for up to 3 months.
• Thaw frozen tofu in the refrigerator before using it.

4. Signs of Spoiled Tofu

It's essential to know the signs of spoiled tofu to avoid consuming it when it's no longer safe:

• Foul odor: If the tofu smells sour, ammonia-like, or off, it's likely spoiled.
• Slimy texture: Spoiled tofu may feel slimy or sticky to the touch.
• Mold growth: Visible mold on the surface of the tofu is a clear indicator of spoilage.
