Frequently Asked Questions

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

As Unopened Refrigerated Tempeh ages, its quality deteriorates due to moisture loss and potential bacterial growth. While tempeh may still be safe to eat after the expiration date if stored correctly, the texture and flavor may change, affecting the overall quality.

How can I tell if Unopened Refrigerated Tempeh has gone bad?

To check if unopened refrigerated tempeh has gone bad, look for any signs of mold growth, discoloration, or a slimy texture.
