Frequently Asked Questions

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

The expiration date on frozen tempeh indicates the last date at which it is recommended to consume the product for food safety reasons. Beyond this date, there is a risk of the tempeh spoiling and causing foodborne illnesses. The best quality date, on the other hand, refers to the period during which the tempeh is at its peak quality in terms of taste and texture. Consuming tempeh before this date ensures the best eating experience, but it can still be safe to eat after this date if stored properly.

How can I tell if Frozen Tempeh has gone bad?

To determine if frozen tempeh has gone bad, inspect for any signs of freezer burn, such as ice crystals or discoloration. Check for any off smells, such as a sour or rancid odor. Lastly, feel the tempeh for any sliminess or unusual texture changes, which can indicate spoilage.

What are the food safety risks?

Frozen tempeh is generally safe to consume, but it is important to handle it properly to prevent foodborne illnesses. Thawed tempeh should not be refrozen as this can affect its texture and quality.
