SUPPLEMENTARY INFORMATION:

I. Introduction

    In the Federal Register of February 8, 2024 (89 FR 8537), we 
announced that we filed a color additive petition (CAP 4C0328) 
submitted by Exponent, Inc., on behalf of Sensient Colors, LLC, 1150 
Connecticut Ave. NW, Suite 1100, Washington, DC 20036. The petition 
proposed to amend the color additive regulations in part 73 (21 CFR 
73.69), ``Listing of Color Additives Exempt from Certification'' to 
provide for the expanded safe use of butterfly pea flower extract to 
include ready-to-eat cereals, crackers, snack mixes, hard pretzels, 
plain potato chips (restructured or baked), and plain corn chips, 
tortilla chips, and multigrain chips, at levels consistent with GMP.
    We note that the notification of filing stated that documents 
related to this petition would be deposited in docket FDA-2018-C-4117. 
This petition has been reassigned to a new docket, docket number FDA-
2024-C-0971. All relevant files from the previous docket

[[Page 20102]]

have been moved into docket number FDA-2024-C-0971.
    This final order is expected to result in expanded production 
options and is considered an E.O. 14192 deregulatory action.

II. Background

    Butterfly pea flower extract is approved under Sec.  73.69 for 
coloring alcoholic beverages, sport and energy drinks, flavored or 
carbonated water, fruit drinks (including smoothies and grain drinks), 
carbonated soft drinks (fruit-flavored or juice, ginger ale, and root 
beer), fruit and vegetable juice, nutritional beverages, chewing gum, 
teas, coated nuts, liquid coffee creamers (dairy and non-dairy), ice 
cream and frozen dairy desserts, hard candy, dairy and non-dairy 
drinks, fruit preparations in yogurts, and soft candy in amounts 
consistent with GMP, except that it may not be used for coloring foods 
for which standards of identity have been issued under section 401 of 
the Federal Food, Drug, and Cosmetic Act (FD&C Act), unless the use of 
added color is authorized by such standards. Butterfly pea flower 
extract is exempt from certification under section 721(c) of 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 (86 
FR 49230, September 2, 2021).
    The color additive that is the subject of this petition is the dark 
blue liquid produced through the water extraction of the dried flower 
petals of Clitoria ternatea, commonly known as the butterfly pea plant. 
Butterfly pea flower extract contains 42 to 62 percent water, 22 to 43 
percent carbohydrates, and 8 to 12 percent proteins. The principal 
coloring components in butterfly pea flower extract are anthocyanins, 
mainly delphinidin derivatives (Ref. 1). The extract also contains 
flavonols, mainly quercetin and kaempferol derivatives, as minor 
components. Based on data and information provided in this petition 
(CAP 4C0328) 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 
butterfly pea flower extract in Sec.  73.69 (Ref. 1).

III. Safety Evaluation

A. Determination of Safety

    Under section 721(b)(4) of the FD&C Act (21 U.S.C. 379e(b)(4)), a 
color additive cannot 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 at 21 CFR 70.3(i) 
define ``safe'' to mean that there is convincing evidence establishing 
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 food 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 
the estimated dietary exposure of the color additive from all sources 
to an acceptable daily intake (ADI) level established by toxicological 
data. The estimated dietary exposure is based on the amount of the 
color additive proposed for use in particular foods and on data 
regarding the amount consumed from all sources of the color additive. 
We commonly use the estimated dietary exposure for the 90th percentile 
consumer of a color additive as a measure of high chronic dietary 
exposure.

B. Safety of Petitioned Use of the Color Additive

    During our safety review of this petition (CAP 4C0328), we 
considered the estimated dietary exposure to butterfly pea flower 
extract, anthocyanins (the main coloring component), total flavonols, 
and quercetin from the petitioned uses of the subject color additive 
(Ref. 2). The petition provided the eaters-only 90th percentile dietary 
exposure for butterfly pea flower extract for the petitioned uses for 
the U.S. population aged 2 years and older, and various subpopulations. 
From that dietary exposure and compositional information incorporated 
by reference from CAP 8C0313, the petitioner also estimated the eaters-
only 90th percentile dietary exposure to anthocyanins, total flavonols, 
and quercetin (Ref. 2).
    The petitioner requested that butterfly pea flower extract be 
permitted at levels consistent with GMP and provided the maximum use 
levels for the color additive, representing GMP, for the petitioned and 
approved food uses (Ref. 2). Using food consumption data from the 2015-
2018 National Health and Nutrition Examination Survey (NHANES), the 
petitioner estimated the eaters-only cumulative dietary exposure to 
butterfly pea flower extract to be 215 milligrams/person/day (mg/p/d) 
at the mean and 467 mg/p/d at the 90th percentile for the U.S. 
population aged 2 years and older and 94 mg/p/d at the mean and 183 mg/
p/d at the 90th percentile for children aged 2-5 years (Ref. 2).
    Assuming a maximum content of 2% anthocyanins (the principal 
coloring component) in butterfly pea flower extract, the petitioner 
estimated the eaters-only cumulative dietary exposure to anthocyanins 
to be 4.3 mg/p/d at the mean and 9.3 mg/p/d at the 90th percentile for 
the U.S. population aged 2 years and older (Ref. 2). The petitioner 
also indicated that the color additive could contain up to 3% flavonols 
and assumed that 50% of the flavonol content was quercetin. Based on 
these assumptions, the petitioner estimated the eaters-only cumulative 
dietary exposure to flavonols (6.4 mg/p/d at the mean and 14 mg/p/d at 
the 90th percentile) and to quercetin (3.2 mg/p/d at the mean and 7 mg/
p/d at the 90th percentile) for the U.S. population aged 2 years and 
older (Ref. 2).
    To support the safety of the petitioned uses of butterfly pea 
flower extract, the petitioner referenced the safety determinations 
made by FDA for CAP 8C0313 (86 FR 49230, September 2, 2021). The 
petitioner also conducted an updated search of the peer-reviewed 
scientific literature on butterfly pea flower extract and Hibiscus 
sabdariffa flower extract (a known source of anthocyanins with a high 
content of delphinidin), as well as on other sources of anthocyanins 
and delphinidins. The petitioner concluded that these publications did 
not reveal any significant new toxicological effects and should not 
alter the conclusions of FDA's previous reviews on butterfly pea flower 
extract. Of the publications submitted by the petitioner, some studies 
had been previously reviewed by FDA. Our review of the new information, 
the information submitted in previously reviewed publications, as well 
as our own independent literature search and review did not reveal any 
safety concerns relating to the consumption of butterfly pea flower 
extract or its major components (Ref. 3).
    In our most recent evaluation of the use of butterfly pea flower 
extract as a color additive in various foods (86 FR 49230, September 2, 
2021), we did not have any concerns regarding the safety of the use of 
butterfly pea flower extract and its principal coloring components, 
anthocyanins and delphinidins. This finding was based on a weight-of-
evidence approach and agreed with the petitioner's conclusion that the 
no observed adverse effect level (NOAEL) in the submitted 90-day study 
was the highest dose tested (3,500 mg/kg/d of butterfly pea flower 
extract), which is nearly 500-fold of the estimated 90th

[[Page 20103]]

percentile dietary exposure for the U.S. population aged 2 years and 
older from the originally petitioned uses. To establish a reasonable 
certainty of no harm for the petitioned expanded uses of butterfly pea 
flower extract, we compared the cumulative estimated dietary exposure 
to the article of commerce and its constituents in the current petition 
to that of the previous petition, as well as to the petitioner's NOAEL 
from their previous 90-day study to develop a margin of exposure (MOE) 
(Ref. 3). Based on the slight increase in the estimated dietary 
exposure to butterfly pea flower extract and its constituents resulting 
from the petitioned expanded uses in this petition above those seen in 
the previous petition, and the high MOE between the observed NOAEL, we 
conclude that these new uses of the color additive are reasonably safe 
under the intended conditions of use (Ref. 3).
    We discussed the potential allergenicity of butterfly pea flower 
extract in our previous approval of a petition for its use in various 
foods (86 FR 49230, September 2, 2021). We stated that there is no 
evidence in the scientific literature specifically suggesting that 
either Clitoria ternatea flowers or the coloring component delphinidin 
is associated with allergic or hypersensitive reactions. The petitioner 
submitted an updated search of the peer-reviewed scientific literature 
and found no new additional publications which suggested an 
allergenicity concern. Further, to mitigate the possible risk that 
allergenic proteins and other large peptides might pose, our regulation 
at 21 CFR 73.69(a)(1) requires that the aqueous extract used to produce 
the color additive undergo ultrafiltration. Therefore, we concluded 
that butterfly pea flower extract presents an insignificant allergy 
risk to consumers of the color additive (Ref. 4).

V. Conclusion

    Based on the data and information in the petition, the referenced 
material, and other relevant material, we conclude that the petitioned 
use of butterfly pea flower extract as a color additive in ready-to-eat 
cereals, crackers, snack mixes, hard pretzels, plain potato chips 
(restructured or baked), and plain corn chips, tortilla chips, and 
multigrain chips, at levels consistent with GMP is safe. We further 
conclude that the color additive will achieve its intended technical 
effect and is suitable for the petitioned uses. Therefore, we are 
amending the color additive regulations in 21 CFR part 73 as set forth 
in this document. In addition, based upon the factors listed in 21 CFR 
71.20(b), we continue to conclude that batch certification of butterfly 
pea flower extract is not necessary to protect the public health.

VI. Public Disclosure

    In accordance with Sec.  71.15(a) (21 CFR 71.15(a)), 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 Sec.  
71.15(b), we will delete from the documents any materials that are not 
available for public disclosure.

VII. Analysis of Environmental Impact

    As stated in the February 8, 2024, Federal Register notification of 
filing for CAP 4C0328, the petitioner claimed that this action is 
categorically excluded under Sec.  25.32(k) (21 CFR 25.32(k)) because 
butterfly pea flower extract would be added directly to food and is 
intended to remain in the food through ingestion by consumers and is 
not intended to replace nutrients in food (89 FR 8537 at 8538). We 
further stated that, if FDA determines a categorical exclusion applies, 
neither an environmental assessment nor an environmental impact 
statement is required (id.). We did not receive any new information or 
comments regarding this claim of categorical exclusion. We considered 
the petitioner's claim of categorical exclusion and determined that 
this action is categorically excluded under Sec.  25.32(k). Therefore, 
neither an environmental assessment nor an environmental impact 
statement is required.

VIII. Paperwork Reduction Act of 1995

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

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

    Our review of this petition was limited to section 721 of the FD&C 
Act. This order is not a statement regarding compliance with other 
sections of the FD&C Act. For example, section 301(ll) of the FD&C Act 
(21 U.S.C. 331(ll)) 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) through (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 order 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 
orders authorizing new uses of color additives 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.

X. Objections

    This order 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 (see 
ADDRESSES) 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
