Common Asked Questions

What's the difference between expiration and best quality dates for Popcorn Unpopped Kernels?

Popcorn kernels do not have an expiration date but rather a best before date. The best before date indicates the period during which the popcorn is expected to retain its optimal quality in terms of taste and texture. While popcorn kernels can technically last indefinitely if stored properly in a cool, dry place, their quality may deteriorate over time, resulting in less fluffy and flavorful popcorn when cooked.

What are the food safety risks with Popcorn Unpopped Kernels?

Popcorn kernels, when unpopped, are generally safe to consume as long as they are stored properly and cooked thoroughly. However, there is a risk of choking if the kernels are not fully popped.
