The U.S. Food and Drug Administration announced on July 14, 2025 that it had granted Gardenia Blue Interest Group’s (GBIG) color additive petition to use the color gardenia (genipin) blue in various foods, at levels consistent with good manufacturing practice. It is the fourth color derived from natural sources approved by the FDA for use in foods in the last two months.

Gardenia (genipin) blue is derived from the fruit of the gardenia, a flowering evergreen. The FDA has approved the color additive for use in sports drinks, flavored or enhanced non-carbonated water, fruit drinks and ades, ready-to-drink teas, hard candy, and soft candy.

The three colors derived from natural sources approved in May were: galdieria extract blue, a blue colorant derived from the unicellular red algae Galdieria sulphuraria; calcium phosphate, a white powder; and butterfly pea flower extract, a blue color that can be used to achieve a range of shades including bright blues, intense purple, and natural greens.

Under section 721 of the Federal Food, Drug, and Cosmetic Act, color additives must be FDA-approved before they may be used in foods. The FDA determines whether a color additive is safe to use by considering the projected human dietary exposure to the color additive, the additive’s toxicological data, and other relevant information, such as published literature. Once the FDA approves a color additive, any manufacturer can use the coloring in accordance with the conditions of use.
