Today, food and color additives, including preservatives, are more strictly studied, regulated and monitored than at any other time in history, and FDA has the primary legal responsibility for determining their safe use. To add a new food preservative to the market, or before using a substance already approved for one use in another application, the manufacturer or other sponsor must obtain approval from the U.S. Food and Drug Administration (FDA) and provide scientific data demonstrating that the substance is safe for its intended use.
