In this blog post, we will explore the shelf life of tofu, signs of spoilage, proper storage techniques, and tips to maximize its longevity.

Tofu Shelf Life: How Long Does Tofu Last?

Tofu typically has a relatively short shelf life compared to some other food products. The shelf life of tofu can vary depending on the type of tofu, its packaging, and how it's stored. Here are some general guidelines to help you understand the shelf life of different types of tofu:

Fresh Tofu

• Unopened: Fresh tofu can last up to 3-5 days in the refrigerator if unopened.
• Opened: Once opened, fresh tofu should be consumed within 3 days for the best quality.

Silken Tofu

• Unopened: Silken tofu can last up to 3-5 days in the refrigerator if unopened.
• Opened: Once opened, silken tofu should be consumed within 3 days.

Firm Tofu

• Unopened: Firm tofu can last up to 1-2 weeks in the refrigerator if unopened.
• Opened: Once opened, firm tofu should be consumed within 5-7 days.

Pre-packaged Tofu

• Pre-packaged tofu usually has a longer shelf life due to its vacuum-sealed packaging. Follow the expiration date on the package for guidance.

Signs of Spoiled Tofu

It's crucial to be able to identify signs of spoiled tofu to prevent foodborne illness. Here are some common indicators that your tofu may have gone bad:

Signs of Spoiled Tofu:

1. Unpleasant odor: Spoiled tofu may have a sour or off-putting smell.
