Bacon is either cured or uncured while all bacon is soaked in brine to give it flavor and prevent botulism. It is traditionally cured using a mixture of salt, water and synthetic sodium nitrite that acts as a preservative and made by mixing Nitrates, a naturally occurring compound in plants, with certain bacteria. Uncured bacon uses natural nitrates found in juice, sea salt and celery powder to achieve a similar taste, so uncured bacon does not have potentially harmful chemicals akin to sodium nitrite.
