The U.S. Food and Drug Administration on Monday approved the use of a new blue color additive from the gardenia fruit the fourth coloring from natural sources added in the last two months.

According to today's announcement from the FDA, an estimated 40% of the food industry has committed to voluntarily phasing out petroleum-based dyes. That includes major brands like Heinz and General Mills, both of which promised this June to start removing synthetic dyes from their products.

The FDA has approved the natural color additive gardenia (genipin) blue for use in various foods and drinks at “levels consistent with good manufacturing practice,” according to an agency press release.
