The US Food and Drug Administration has put a spotlight on food dyes this year. In January, the administration banned Red No. 3 and then approved three natural food dyes in May. Now, on top of the FDA and Department of Health and Human Services asking food companies to stop using petroleum-based synthetic dyes entirely, the FDA wants brands to speed up the removal of Red No. 3 before the proposed 2027 deadline. To help this along, the administration just green-lit a new natural blue food dye, gardenia (genipin) blue.
According to the FDA, this blue dye comes from the fruit of the gardenia, a flowering evergreen. It can be used in hard and soft candy, sports drinks, ready-to-drink teas, flavored or enhanced noncarbonated water, fruit drinks and ades.
"This expedited timeline underscored our serious intent to transition away from petroleum-based synthetic dyes in the food supply," said FDA Commissioner Marty Makary in a news release. "Now, by expanding the palette of available colors derived from natural sources, food manufacturers have a variety of options available that will make it easier to end their use of petroleum-based dyes."
Gardenia (genipin) blue joins the red algae-based galdieria extract blue, butterfly pea flower extract and the white color calcium phosphate as 2025's new and approved natural food color additives.

What is gardenia (genipin) blue?
The FDA approved the use of gardenia (genipin) blue from a petition by the Gardenia Blue Interest Group. According to the FDA's order, gardenia (genipin) blue is a dark purple or blue liquid made from the mature fruit of the Gardenia jasminoides Ellis plant with soy protein hydrolysate.
Now, you may be thinking: Isn't soy an allergen? According to the GBIG, the soy protein allergens aren't expected to be detected in the final color additive because "unreacted protein hydrolysate is removed during manufacturing."
Because no soy protein allergens will be in the final product, the GBIG is asking to be exempt from food allergen labeling. The FDA is currently reviewing this petition.
