Selecting a blue color for a sports drink and selecting one for a carbonated drink are not necessarily the same regulatory task. The text of 21 CFR 73.168 retrieved for this article lists sports drinks, flavored or enhanced noncarbonated water, fruit drinks and ades, ready-to-drink teas, hard candy and soft candy; a separate August 2026 notice identifies carbonated drinks and powdered beverages among proposed additional uses.[1][2] On retrieval, FDA’s petition database still described CAP 6C0343 as “under review,” with a status update date of August 4, 2026—not approved.[3]
The practical question comes before color optimization: do the proposed material and finished-food category meet the terms of the relevant authorization?
The fresh signal is a petition, not a blanket extension
The July 15, 2025 approval order took effect on August 29, 2025. FDA confirmed that effective date in its October 1 notice after receiving no objections or hearing requests. That date applies to the original six use categories, not the 2026 expansion petition.[7]
The August 19, 2026 Federal Register document is explicitly a “Notification of petition.” Filed by FDA on August 4, the petition proposes 20 additional uses, including carbonated drinks, powdered beverages, flavored milk, flavored and unflavored yogurt, ice cream and other frozen desserts; it also proposes lowering the arsenic specification for the color additive from no more than 2 mg/kg to no more than 1 mg/kg.[2]
These categories can inform a development watchlist, but a petition does not itself authorize a use. The eCFR text retrieved for this article still specifies arsenic at no more than 2 mg/kg, while 1 mg/kg appears in the expansion petition.[1][2] These are specifications for the color additive—not concentrations in the finished drink or human intake limits.[1][2]
| Product concept | What the retrieved primary sources establish | Purchasing implication |
|---|---|---|
| Product conceptA sports drink fitting the listed category | What the retrieved primary sources establishListed in 73.168, subject to GMP and the standards-of-identity restriction.[1] | Purchasing implicationProceed to applicability review; do not describe a particular commercial product as individually approved. |
| Product conceptFlavored or enhanced noncarbonated water | What the retrieved primary sources establishThe regulation expressly says noncarbonated.[1] | Purchasing implicationDo not carry that rationale unchanged into a carbonated reformulation; reassess the final category. |
| Product conceptCarbonated drinks or powdered beverages | What the retrieved primary sources establishExpressly included in the 2026 expansion petition.[2] | Purchasing implicationDo not use a pending petition as the authorization for that category.[3] |
| Product conceptFlavored milk, yogurt or ice cream | What the retrieved primary sources establishIncluded in the expansion petition.[2] | Purchasing implicationHave regulatory staff check classification and subsequent decisions before committing to launch. |
Complex beverages still need to be classified by their final formulation and product characteristics. A listing for noncarbonated water does not establish that every carbonated drink is covered.
The purchase is not simply “gardenia extract”
The US listing defines a specific material. Gardenia (genipin) blue is prepared by reacting genipin extracted from the fruit of Gardenia jasminoides Ellis with soy protein hydrolysate; the principal coloring component is a genipin-peptide polymer.[1] The 2025 order describes liquid and powder forms, with water in the liquid form and carriers in the powder form; its manufacturing description includes adding dextrin or maltodextrin before spray-drying.[4]
A quotation headed only “Gardenia extract” therefore does not establish that the quoted material is the blue color defined in this listing. Composition and manufacturing route establish that identity more reliably than the botanical name on a quotation.
Start the brief with the intended US food category and the specific color-additive identity, then request the actual commercial composition, manufacturing-route declaration and specification. A higher assay for a botanical marker is not a substitute for establishing the identity of the coloring material.
The regulation also requires the powdered additive’s label to declare additional ingredients used in manufacture and restricts the diluents permitted in color-additive mixtures.[1] For development, this suggests comparing liquid and powder formats by the amount needed to reach the intended color, the ingredient-list consequences and processing behavior—not merely price per kilogram. The dose needed to reach a comparable shade has to be measured in the target formulation.
Why a nondetect result does not establish an allergen-labeling exemption
Two passages in the 2025 approval document need to be read together. The petitioner supplied an enzyme-linked immunoassay result reporting nondetectable soy-protein residue in the final commercial article. Yet the same document’s “Allergen Labeling” section stated at that time that the color additive required allergen labeling because soy protein hydrolysate is used in manufacture, unless an exemption is obtained through the specified process.[4]
Those passages answer different questions: what an analytical test reported, and whether a legal labeling exemption has been obtained. Do not convert “not detected” into “soy-free,” or convert approval as a food color into approval of a soy-labeling exemption.
The July 15, 2025 order said that a separate allergen-labeling exemption petition, submitted by GBIG on September 29, 2022, was then under review.[4] This research did not obtain a final decision on that exemption as of September 2026. It therefore does not claim that the exemption is still pending today—or that it has been granted. If a project requires omission of a soy declaration, request the formal decision applicable to the material and have regulatory staff review it. Neither an assay report nor an old color-approval announcement closes that question by itself.
Exempt from batch certification does not mean exempt from specifications
Section 73.168(e) provides a specific exemption from color-additive batch certification. The same section still sets identity, impurity, use and labeling requirements.[1] FDA’s color-status database likewise says “Permanently listed, exempt from certification” while specifying restricted uses.[5]
This is not evidence of a supplier’s business certification or proof that a particular lot meets every specification. A buyer can recognize the regulatory batch-certification exemption and still require relevant lot analysis and traceability. These are different kinds of evidence.
Read the original specifications together with the correction
The July 2025 order printed a methanol limit of 6 mg/kg. The official August 6 correction replaced it with 300 mg/kg, effective August 29 alongside the approval order. This corrected a misstatement in the original order; it was not the arsenic change proposed in the 2026 petition.[4][6]
A purchasing specification should therefore not be copied from the first approval announcement alone. The retrieved eCFR text lists methanol at 300 mg/kg and arsenic at 2 mg/kg, but the extraction did not show an explicit consolidation-through date. For the uses and values discussed here, this analysis cross-checks the approval and correction documents against FDA’s color inventory and petition status record rather than treating the retrieval date as the regulation’s consolidation date.[1][3][5]
Put development effort behind the right decision
For a product fitting an existing listed category, the suggested sequence is to resolve material identity, category applicability, ingredient declaration and allergen handling before investing in target-matrix color and process trials. Useful development observations may include color before and after heat treatment, color change during storage and behavior in the intended package. This article does not establish a stability ranking against butterfly pea or other blues, recommend a use level, or predict shelf life.
For a project relying only on the 2026 expansion petition, separate exploratory bench work from a commercial launch commitment. Collecting technical information can prepare a later decision; it cannot turn “the petition covers this category” into “this category has been approved.”[2][3]
A useful sample request should identify the destination market, final food category, preferred liquid or powder format, target shade and process conditions. Combining those requirements with the actual composition and specifications makes competing supply proposals easier to compare. Good selection begins before the blue prototype: establish which material is being supplied, which product it will color, and what the supporting document actually authorizes.
