SUPPLEMENTARY INFORMATION:

I. Introduction

In a notice published in the Federal Register of September 16, 2016 (81 FR 63728), we announced that we filed a color additive petition (CAP 6C0306) submitted by McCormick & Company, Inc., c/o Exponent, 1150 Connecticut Ave. NW., suite 1100, Washington, DC 20036. The petition proposed to amend the color additive regulations in ��?73.530 (21 CFR 73.530) Spirulina extract to provide for the expanded safe use of spirulina extract, prepared by the filtered aqueous extraction of the dried biomass of Arthrospira platensis, to seasonally color the shells of hard-boiled eggs. The color additive is intended to be sold as a powder in a packet to consumers at levels consistent with GMP.

II. Background

Spirulina extract is currently approved under ��?73.530 for coloring confections (including candy and chewing gum), frostings, ice cream and frozen desserts, dessert coatings and toppings, beverage mixes and powders, yogurts, custards, puddings, cottage cheese, gelatin, breadcrumbs, ready-to-eat cereals (excluding extruded cereals), and coating formulations applied to dietary supplement tablets and capsules, at levels consistent with GMP. Spirulina extract also is currently approved under21 CFR 73.1530for coloring coating formulations applied to drug tablets and capsules, at levels consistent with GMP. Spirulina extract is exempt from certification under section 721(c) of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 379e(c)) because we previously determined that certification was not necessary for the protection of public health (78 FR 49117at 49119, August 13, 2013).

The spirulina extract that is the subject of this final rule is a blue-colored powder produced by the filtered aqueous extraction of the dried biomass of A. platensis (also known as Spirulina platensis), an edible blue-green cyanobacterium. The color additive contains phycocyanins as the principal coloring components. Based on data and information provided in the petition on the identity, physical and chemical properties, manufacturing process, and composition of the color additive, we have determined that the color additive meets the specifications for spirulina extract in ��?73.530 (Ref. 1).

Spirulina-derived ingredients have also been the subject of four notices submitted by firms to FDA informing us of their determinations that certain uses of these substances in food are generally recognized as safe (GRAS) (78 FR 49117at 49118). Under section 201(s) of the FD&C Act (21 U.S.C. 321(s)), a substance that is GRAS for a particular use in food is not a food additive, and may lawfully be utilized for that use without our review and approval. There is no GRAS exemption, however, to the definition of color additive in section 201(t) of the FD&C Act). Therefore, we must approve the use of a color additive in food before it is marketed; otherwise the food containing the color additive is adulterated under section 402(c) of the FD&C Act (21 U.S.C. 342(c)). One GRAS Start Printed Page 30733notice (GRN 000424) pertains to the use of a spirulina-derived substance that is similar in chemical composition to the color additive that is the subject of this final rule, but the substance that was the subject of GRN 000424 has a much higher phycocyanin content (Ref. 3). Importantly, in our response to these GRAS notifications, we indicated that if the substances that were the subject of these submissions impart color to the food, they may be subject to regulation as a color additive.

III. Safety Evaluation

A. Determination of Safety

Under section 721(b)(4) of the FD&C Act, a color additive may not be listed for a particular use unless the data and information available to FDA establish that the color additive is safe for that use. Our color additive regulations at21 CFR 70.3(i) define ��safe�� to mean that there is convincing evidence that establishes with reasonable certainty that no harm will result from the intended use of the color additive. To establish with reasonable certainty that a color additive intended for use in foods is not harmful under its intended conditions of use, we consider the projected human dietary exposure to the color additive, the additive's toxicological data, and other relevant information (such as published literature) available to us. We compare an individual's estimated exposure, or estimated daily intake (EDI), of the color additive from all food sources to an acceptable daily intake level established by toxicological data. The EDI is determined by projections based on the amount of the color additive proposed for use in particular foods or drugs and on data regarding the amount consumed from all ingested sources of the color additive. We commonly use the EDI for the 90th percentile consumer of a color additive as a measure of high chronic exposure.

B. Safety of Petitioned Use of the Color Additive

During our safety review of this petition (CAP 6C0306), we considered the projected human dietary exposure to spirulina extract and to phycocyanins (the principal coloring components) from the petitioned use and from currently permitted uses of spirulina extract in foods and ingested drugs. McCormick submitted an exposure estimate for spirulina extract and for phycocyanins for the petitioned use of spirulina extract based on a worst-case scenario that presumed that spirulina extract could potentially migrate from the outside of the egg shell to the edible portion of the egg. McCormick estimated that the petitioned use of spirulina extract to seasonally color the shells of hard-boiled eggs would result in an exposure to spirulina extract of 8.8 milligrams per person per day (mg/p/d) at the 90th percentile for the U.S. population aged 2 years and older (Ref. 2). McCormick also estimated that the petitioned use of spirulina extract would result in an exposure to phycocyanins of 1.9 mg/p/d at the 90th percentile for the U.S. population aged 2 years and older (Ref. 2). Despite providing this worst-case estimate, McCormick noted that egg shells are not consumed and demonstrated that the spirulina extract applied to the outside of an egg shell generally does not migrate through the shell and the outer and inner membranes separating the shell from the edible portion of the egg. For these reasons, McCormick asserted that the amount of spirulina extract that would actually be found on the edible portion of an egg would be negligible, resulting in a 0.17 percent increase of the cumulative estimated daily intake (CEDI) for phycocyanins (Ref. 2). The previously estimated upper bound CEDI for phycocyanins from all GRAS-notified uses of spirulina extract in food is 1,140 mg/p/day or 19 milligrams per kilogram body weight per day (mg/kg bw/d) for a 60 kg individual based on uses addressed in GRN 000424 (Ref. 3). We agree that McCormick's exposure estimate is sufficiently conservative. We conclude that the exposure to spirulina extract and phycocyanins resulting from the petitioned use of spirulina extract to seasonally color the shells of hard-boiled eggs is negligible, and that the petitioned use would not result in a significant contribution to the CEDI for phycocyanins (Ref. 2).

To support the safety of the proposed use of spirulina extract to color the shells of hard-boiled eggs, McCormick referenced the safety determinations made by FDA for CAPs 2C0293 (78 FR 49117, August 13, 2013), 2C0297 (79 FR 20095, April 11, 2014), and 4C0300 (80 FR 50762, August 21, 2015). McCormick also conducted a search of the peer-reviewed scientific literature for animal and human oral consumption studies that tested spirulina, spirulina-derived ingredients, and phycocyanins that were published between January 1, 2014, and July 20, 2016. McCormick submitted to us the published animal and human studies that they identified as being relevant to their petition. We evaluated the submitted safety information and additional studies that we identified as relevant and concluded that this information does not raise any safety concerns (Refs. 4 and 5).

In our previous evaluation of the use of spirulina extract as a color additive in foods (80 FR 50762), we did not have any concerns regarding the safety of the use of spirulina extract and its major coloring components, phycocyanins. Taking into account all the available safety information and the estimated exposure to phycocyanins from the petitioned use, we conclude that the proposed use of spirulina extract to seasonally color the shells of hard-boiled eggs is safe (Ref. 5).

We discussed the potential allergenicity of spirulina phycocyanins in our final rule for the use of spirulina extract as a color additive in candy and chewing gum (78 FR 49117at 49119). Based on the comparison of the known amino acid sequences of phycocyanins with the sequences of known protein allergens, we determined that there is a low probability that phycocyanins are protein allergens. We therefore concluded that the spirulina phycocyanins present an insignificant allergy risk. Additionally, after a review of the literature relevant to the potential allergenicity of spirulina phycocyanins, we have determined that spirulina phycocyanins still present an insignificant allergy risk (Refs. 4-7). We are not aware of any new information that would cause us to change this conclusion.

IV. Conclusion

Based on the data and information in the petition and other relevant material, we conclude that the petitioned use of spirulina extract to seasonally color the shells of hard-boiled eggs is safe. We further conclude that the color additive will achieve its intended technical effect and is suitable for the petitioned use. Consequently, we are amending the color additive regulations in part 73 (21 CFR part 73) as set forth in this document. In addition, based upon the factors listed in21 CFR 71.20(b), we continue to conclude that certification of spirulina extract is not necessary for the protection of the public health.

V. Public Disclosure

In accordance with ��?71.15 (21 CFR 71.15), the petition and the documents that we considered and relied upon in reaching our decision to approve the petition will be made available for public disclosure (see FOR FURTHER INFORMATION CONTACT). As provided in ��?71.15, we will delete from the documents any materials that are not available for public disclosure.Start Printed Page 30734

VI. Analysis of Environmental Impact

We previously considered the environmental effects of this rule, as stated in the September 16, 2016, Federal Register notice of petition for CAP 6C0306 (81 FR 63728). We stated that we had determined, under21 CFR 25.32(r), that this action ��is of a type that does not individually or cumulatively have a significant effect on the human environment�� such that neither an environmental assessment nor an environmental impact statement is required. We have not received any new information or comments that would affect our previous determination.

VII. Paperwork Reduction Act of 1995

This final rule contains no collection of information. Therefore, clearance by the Office of Management and Budget under the Paperwork Reduction Act of 1995 is not required.

VIII. Section 301(ll) of the FD&C Act

Our review of this petition was limited to section 721 of the FD&C Act. This final rule is not a statement regarding compliance with other sections of the FD&C Act. For example, section 301(ll) of the FD&C Act prohibits the introduction or delivery for introduction into interstate commerce of any food that contains a drug approved under section 505 of the FD&C Act (21 U.S.C. 355), a biological product licensed under section 351 of the Public Health Service Act (42 U.S.C. 262), or a drug or biological product for which substantial clinical investigations have been instituted and their existence has been made public, unless one of the exemptions in section 301(ll)(1) to (ll)(4) of the FD&C Act applies. In our review of this petition, we did not consider whether section 301(ll) of the FD&C Act or any of its exemptions apply to food containing this color additive. Accordingly, this final rule should not be construed to be a statement that a food containing this color additive, if introduced or delivered for introduction into interstate commerce, would not violate section 301(ll) of the FD&C Act. Furthermore, this language is included in all color additive final rules that pertain to food and therefore should not be construed to be a statement of the likelihood that section 301(ll) of the FD&C Act applies.

IX. Objections

This rule is effective as shown in the DATES section, except as to any provisions that may be stayed by the filing of proper objections. If you will be adversely affected by one or more provisions of this regulation, you may file with the Dockets Management Staff (seeADDRESSES) either electronic or written objections. You must separately number each objection, and within each numbered objection you must specify with particularity the provision(s) to which you object, and the grounds for your objection. Within each numbered objection, you must specifically state whether you are requesting a hearing on the particular provision that you specify in that numbered objection. If you do not request a hearing for any particular objection, you waive the right to a hearing on that objection. If you request a hearing, your objection must include a detailed description and analysis of the specific factual information you intend to present in support of the objection in the event that a hearing is held. If you do not include such a description and analysis for any particular objection, you waive the right to a hearing on the objection.

Any objections received in response to the regulation may be seen in the Dockets Management Staff between 9 a.m. and 4 p.m., Monday through Friday, and will be posted to the docket athttps://www.regulations.gov. We will publish notice of the objections that we have received or lack thereof in the Federal Register.
