Introduction
Food colors, also referred to as food colorants or color additives, are a category of food additives used to impart or restore color to foods, enhance sensory attributes, and increase consumer appeal. They are widely used across nearly every food category, including beverages, bakery products, dairy, snacks, and processed meat products.
Food colors are primarily categorized into two types based on their source and properties: natural and synthetic. Natural colors are derived from plant and animal tissues or microorganisms. Their "all-natural" profile aligns perfectly with consumer health trends. Synthetic colors, produced through chemical synthesis, offer vibrant hues, high coloring potency, low cost, and excellent stability, allowing them to dominate the food colors market for decades.
However, tightening regulation requirements, technological innovation, and evolving consumer expectations are reshaping the industry. The global food colors regulations are undergoing a structural shift toward natural alternatives, creating new regulatory challenges and opportunities for food colors manufacturers.
Regulatory Shift Toward Natural Food Colors Worldwide
European Union: Mandatory Warning Labels Accelerate the Shift Away from Synthetic Colors
The European Union has long maintained one of the most stringent regulatory frameworks for food colors.
Under Regulation (EC) No 1333/2008 on food additives, foods containing certain synthetic colors must carry a mandatory warning statement indicating that “may have an adverse effect on activity and attention in children.”
This requirement applies to the following six food colors:
Tartrazine (E102)
Quinoline Yellow (E104)
Sunset Yellow FCF (E110)
Carmoisine (E122)
Ponceau 4R (E124)
Allura Red (E129)
The labeling requirement significantly reduced the use of these synthetic colors in food and beverage products within the EU and accelerated the transition toward natural colors.
United States: Policy Momentum Toward Phasing Out Petroleum-Based Synthetic Dyes
In the United States, regulatory attention toward petroleum-based synthetic dyes has intensified in recent years.
In January 2025, the U.S. Food and Drug Administration (FDA) revoked the authorization of FD&C Red No. 3 (Erythrosine) for use in foods, beverages, dietary supplements, and orally administered drugs.
In April 2025, the FDA announced a broader initiative to phase out eight petroleum-derived synthetic dyes by the end of 2026, including:
Citrus Red No. 2
Orange B
FD&C Red No. 40
FD&C Yellow No. 5
FD&C Yellow No. 6
FD&C Blue No. 1
FD&C Blue No. 2
FD&C Green No. 3
The revocation process for two synthetic food colors, Citrus Red No. 2 and Orange B, has already begun, while the remaining six synthetic dyes are expected to be gradually removed from the U.S. food supply chain through collaboration between regulators and major industry players by the end of 2026.
Meanwhile, regulatory support for natural alternatives is also increasing.
As of February 2026, a total of six new food colors have been authorized under the Trump administration. Additionally, in an open letter to the food industry regarding “No Artificial Colors” labeling, the FDA clarified that products not containing any FD&C Act-certified colors may use the claim “No Artificial Colors.”
Furthermore, in the FDA Human Foods Program Priorities for 2026, the agency identified transitioning from petroleum-based dyes to natural alternatives and accelerating the review of new natural colors as key regulatory priorities.
Industry Response: Major Food Companies Are Acting
Global food manufacturers are already adapting to the changing regulatory and consumer landscape.
Several multinational companies have announced timelines to reduce or eliminate synthetic food colors:
Hershey plans to remove synthetic colors from its U.S. confectionery and snack portfolio by the end of 2027.
Kraft Heinz has committed to transitioning to non-artificial color systems across its U.S. products by 2027.
PepsiCo has launched several “no artificial colors” versions of flagship snack brands such as Lay’s potato chips and tortilla chips.
Mars has already prioritized the phase-out of synthetic colors in the European market and will offer synthetic-color-free versions of M&M’s, Skittles, and Starburst in the United States starting in 2026.
This global convergence reflects not only regulatory pressure but also consumer demand for “clean label” and “naturally sourced” colors.
Technology Transformation — From Plant Extraction to Precision Fermentation
One major challenge in replacing synthetic colors lies in performance and dosage requirements. Natural colors often have lower color intensity and weaker stability than synthetic colors. As a result, achieving the same shade may require multiple times—sometimes up to ten times—the dosage of natural colors.
For example, the U.S. demand for Sunset Yellow FCF (FD&C Yellow No. 6) was approximately 2,500 tons in 2025. If replaced entirely by natural alternatives, the required volume of natural colors would increase dramatically, creating substantial new market demand.
According to industry data, the global natural food colors market was valued at USD 1.7 billion in 2024 and is projected to reach USD 3.5 billion by 2032, with a compound annual growth rate (CAGR) of approximately 9.4%.
The Limits of Traditional Extraction
However, more than half of current natural colors still rely on plant extraction, which faces several challenges:
Seasonal fluctuations in raw material supply
Limited stability under heat, light, or varying pH conditions
Potential impact on product flavor
Production capacity constraints
Precision Fermentation: A New Generation of Natural Colors
Biomanufacturing technologies, particularly precision fermentation, are emerging as a promising solution to these challenges. Companies are now using microbial fermentation platforms to produce natural colors with improved functionality and scalability.
One example is Michroma, which uses filamentous fungi fermentation to produce a red pigment known as Red+. This pigment demonstrates high stability under heat, light, and varying pH conditions, while maintaining neutral flavor characteristics.
Importantly, fermentation-derived pigments can also meet dietary requirements such as:
Vegan and vegetarian diets
Kosher certification
These properties make them suitable for applications in bakery products, dairy foods, and meat alternatives, areas where traditional plant colors may struggle.
Other biotechnology companies, including Chromologics and Phytolon, are also developing next-generation microbial pigments, redefining the performance standards for natural colors.
The White Colors Challenge
One of the most difficult technological gaps in natural colors development is white colors, traditionally dominated by Titanium Dioxide (TiO₂).
Following regulatory restrictions on TiO₂ in some markets, several companies are developing alternative solutions:
ADM and Cargill are using corn starch or modified rice flour structures to create light-scattering effects that mimic whitening properties.
Blue California has developed CleanWhite, a cellulose-based ingredient produced through synthetic biology, designed to deliver functionality close to TiO₂.
Compliance Outlook — Strategic Actions for Food Manufacturers
As the food colors industry enters a period of regulatory tightening and rapid technological transformation, food manufacturers must adopt proactive compliance strategies.
Three key actions are recommended:
Comprehensive Compliance Audit: Conduct a global gap analysis against evolving standards. Replace "at-risk" synthetic colors, verify supplier certifications, and ensure proper labeling and documentation to minimize compliance risks.
Strategic Pipeline Mapping: Align R&D with biomanufacturing trends. Prioritize the adoption of fermentation-derived pigments that match the regulatory trajectory of your target markets.
Long-term Compliance Systems: Move beyond reactive fixes. Establish an integrated compliance management system to transform regulatory compliance into a core competitive advantage.
