Frequently Asked Questions

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

1. The expiration date indicates when the Komatsuna may no longer be safe to consume, while the best quality date suggests when it may start to decline in taste and texture. 2. Signs of quality degradation include wilting, yellowing, or a loss of crispness. Actual spoilage is marked by mold, foul odor, or sliminess. 3. Komatsuna typically maintains peak quality for about 1 week when stored properly in the refrigerator. 4.

How can I tell if Komatsuna has gone bad?

To check if Komatsuna has gone bad, look for wilting or yellowing leaves, a slimy texture, or a sour or unpleasant odor.

If the leaves are limp, slimy, or have a strong odor, it is best to discard it to avoid any potential foodborne illnesses.
