How to store

We recommend a period of 57 days as a window of time for refrigeration of fresh celery. While some nutrients appear to be stable in whole, refrigerated celery for longer periods of time, several studies show greater losses of phenolic antioxidants in celery after this weeklong period. In addition, based on changes in flavonoid content, we also recommend that you wait to chop up your celery just before you are adding it to a salad or cooked dish (rather than chopping it up the night before and leaving it stored in the refrigerator overnight). If you find yourself needing to cut up celery far ahead of time, in a way that requires overnight storage in your refrigerator, we recommend that you place the cut celery into a hard plastic or glass container instead of a soft plastic bag. Since the cutting of celery will expose more of its surface area, you can avoid increased contact of more celery surfaces to the less stable materials that are found in soft plastic bags by using more sturdy containers for your cut celery.
