Celery powder Celery powder Celery powder is a dried, ground concentrate prepared from fresh celery that is used as a seasoning and as a food preservative in organic meat products. Several commercial preparations exist, and it can also be made using a food dehydrator. Some celery powders are prepared from celery juice. Celery powder contains a significant amount of naturally occurring nitrate and is often treated with bacterial cultures to produce nitrite. In the United States, treated celery powder is sometimes used as a food preservative in organic meat products, which is allowed per USDA regulations because the nitrate/nitrite is naturally occurring.
