Frequently Asked Questions

What's the difference between expiration and best quality dates?

Over time, opened refrigerated tofu may lose its texture, develop off flavors, and become slimy or discolored. While it may still be safe to eat for a short period beyond the expiration date if properly stored, the quality deteriorates. It's recommended to consume tofu by the 'best by' date for optimal taste and texture.

How can I tell if Opened Refrigerated Tofu has gone bad?

When checking if opened refrigerated tofu has gone bad, look for any signs of mold, discoloration, or an off smell. Fresh tofu should have a neutral smell and a smooth, slightly firm texture. If the tofu appears slimy, has a sour smell, or feels mushy, it is likely spoiled and should be discarded.

What are the food safety risks?

Opened Refrigerated Tofu may pose a risk of contamination with bacteria such as Listeria monocytogenes or Salmonella if not stored properly. To prevent foodborne illnesses, always refrigerate tofu at or below 40°F (4°C), consume it within 3-5 days of opening, and avoid cross-contamination with raw meat or poultry.

What are some pro storage tips?

To extend the shelf life of opened refrigerated tofu, store it in a container filled with fresh water and change the water daily to maintain freshness. For added flavor, marinate tofu in soy sauce, spices, or citrus juices before cooking. Tofu can also be frozen for up to 3 months, but the texture may change upon thawing.

Any interesting facts about Opened Refrigerated Tofu?

Can I eat Opened Refrigerated Tofu if it has been at room temperature for a few hours?
