Natural green color in baked goods: What the U.S. spirulina expansion means
The U.S. Food and Drug Administration (FDA) has expanded the permitted uses of spirulina extract as a color additive, opening new possibilities for natural green in baked goods.
The amendment allows spirulina extract to be used in human food generally, including incorporation into baked batters and dough systems. Previously, spirulina-based blue colors could be applied to decorative bakery components, but not directly within baked products themselves under U.S. regulation.
Following a petition submitted by GNT, this regulatory update removes a longstanding constraint for bakery teams. What has long been standard practice across Europe and other regions can now be implemented with regulatory clarity in the U.S. market.
As a result, bakery teams can now combine spirulina blues with plant-based yellows to achieve bold green shades in almost any application.
New possibilities for natural green in baked goods
For many concepts, natural green is about subtle flavor signaling. A light green crumb in a layered key lime cake can reinforce citrus notes and create visual differentiation without overpowering the product’s natural appearance.
Green also supports more indulgent or premium concepts. Pistachio cheesecakes, matcha-inspired pound cakes, and layered desserts benefit from a soft to moderate green tone that communicates flavor before the first bite.
Beyond subtle greens, deeper and more expressive tones are also possible. Higher-intensity spirulina formats can support more saturated greens and blue-forward bakery concepts, expanding the visual range available to developers.
From citrus and pistachio to seasonal, celebratory, or limited-time themes, natural green and blue shades can now be explored more freely within baked systems for the U.S. market.
Examples of natural green and blue shades incorporated directly into baked applications, from layered key lime cake, match-inspired pound cake, and ombre spirulina-colored cookies.
Developing natural green in baked systems requires balancing shade intensity, format, and baking conditions.
The following principles help guide formulation.
1. Account for oven heat
Spirulina extract is sensitive to extended heat exposure. During baking, some reduction in blue intensity can occur.
To achieve the desired crumb shade, batters and doughs are typically formulated with slightly higher intensity than the final color target, ensuring the baked result aligns with the intended green tone.
2. Balance blue and yellow after baking — not before
Natural green is created by blending spirulina extract with a yellow component.
While spirulina may soften during baking, many yellow color sources — including turmeric- and carotene-based options — are highly heat stable and can maintain or even brighten in tone.
As a result, pre-bake batters may be formulated with a slightly more blue-leaning shade to achieve the correct green balance after oven exposure. This post-bake hue adjustment is a critical part of successful green development in bakery systems.
3. Select the right color format
Format plays an important role in performance, handling, and cost-in-use:
- Liquid colors may be well suited for incorporation through high-water ingredients.
- Powder formats can integrate efficiently into dry blends, cake mixes, or fat/sugar creaming phases.
- For applications targeting stronger green or blue tones, concentrated spirulina powder formats can help deliver higher color intensity while managing overall inclusion levels.
- In fat-containing systems such as cookies and cakes, oil-soluble carotene formats may support efficient dispersion, while water-dispersible options remain suitable depending on formulation preferences.
Selecting the appropriate format supports uniform distribution, shade consistency, and practical formulation outcomes.
4. Expect surface browning
During the heating stage, caramelization and Maillard reactions naturally create a browned exterior in baked goods. This is expected and should not be interpreted as color instability.
Designing around this visual contrast — brown exterior, green interior — is part of developing realistic and appealing natural bakery concepts. Natural green tones are most visible within the crumb once sliced.

A broader opportunity for natural green innovation in bakery
For manufacturers targeting the U.S. market, the recent FDA amendment provides greater clarity for incorporating spirulina extract directly into baked goods.
Successful development still depends on thoughtful formulation, appropriate format selection, and alignment between target shade and bake profile.
With the right approach, brands can now deliver green and blue shades within batters and dough systems, opening new paths for product innovation.
Natural green in baked goods is no longer a workaround. It is a viable path for bakery development in the U.S.
