4. Storage: To keep walnut kernels fresh, they should be stored in an airtight container in a cool, dry place. They can also be refrigerated or frozen to extend their shelf life.

5. Allergies: Some people may be allergic to walnuts, so it's important to be aware of any potential allergic reactions if consuming or serving them.
