ABSTRACT
Following a request from the European Commission, the Panel on Food Additives and Nutrient Sources added to
Food (ANS) was asked to deliver an opinion on the safety of “iodized ethyl esters of poppy seed oil” (ethyl
esters of iodinated fatty acids of poppy seed oil, EEIFAPSO) and the bioavailability of the iodine from this source
when used for the fortification of vegetable oils with iodine. The safety of iodine itself, in terms of amounts that
may be consumed, is outside the remit of this Panel. EEIFAPSO are described as a mixture of ethyl palmitate,
ethyl stearate, ethyl monoiodostearates, ethyl diiodostearates and ethyl triiodostearates. The iodine content of
EEIFAPSO is 37-39 % (w/w) and the source is intended to be added at the concentration of 2.76-3.05 mg of
EEIFAPSO per kg of vegetable oil. The Panel noted that kinetic data referring to exposure conditions of
fortification are limited and that available results are indicating that a possible bioaccumulation of EEIFAPSO
and/or their metabolites may occur. Furthermore the available data did not allow a quantitative assessment of the
bioavailability of iodine from EEIFAPSO. No data are available on short-term, subchronic and chronic toxicity,
carcinogenicity and reproductive toxicity of EEIFAPSO. Overall the Panel could not conclude on the safety of
EEIFAPSO as a source of iodine in food fortification and on the bioavailability of iodine from this source due to
data gaps in the kinetic and the dynamic properties of the different iodinated compounds in EEIFAPSO.

SUMMARY
Following a request from the European Commission to the European Food Safety Authority (EFSA),
the Panel on Food Additives and Nutrient Sources added to Food (ANS) was asked to deliver an
opinion on the safety of “iodized ethyl esters of poppy seed oil” (ethyl esters of iodinated fatty acids of
poppy seed oil, EEIFAPSO) and the bioavailability of the iodine from this source when used for the
fortification of vegetable oils with iodine. The safety of iodine itself, in terms of amounts that may be
consumed, is outside the remit of this Panel.

EEIFAPSO are described as a mixture of ethyl palmitate, ethyl stearate, ethyl monoiodostearates, ethyl
diiodostearates and ethyl triiodostearates. The source is intended to be added at the concentration of
2.76-3.05 mg of EEIFAPSO per kg of vegetable oil. The iodine content of EEIFAPSO is 37-39 % (w/w)
and the resulting final iodine content in the iodine-enriched vegetable oils amounts to 1.021 to 1.190
mg/kg.

The Panel considered that EEIFAPSO are a mixture containing potentially a variety of 14 positional
isomers of the ethyl esters of mono-, di-, or triiodostearic acid, each existing in the form of two to
eight stereoisomers. The relative proportions of the isomers present in EEIFAPSO were not indicated by
the applicant.

Kinetic studies in humans with oral administration of EEIFAPSO in a single high dose followed by
observations for up to one year showed that iodine was retained in the body and progressively released
over a long time period. The Panel noted that this was indicative of a long half life of EEIFAPSO or
their metabolites.

The Panel also noted that kinetic data referring to exposure conditions of fortification are limited and
that available results indicate that a possible bioaccumulation of EEIFAPSO and/or their metabolites
may occur. Furthermore the available data did not allow a quantitative assessment of the
bioavailability of iodine from EEIFAPSO.

The Panel was aware of results showing that monoiodostearic acid esters or their metabolites have a
higher retention in the organism than diiodostearic acid esters or their metabolites and will therefore
release iodide for longer periods. Thus the Panel presumed that different iodinated components in
EEIFAPSO such as ethyl mono-, di- and triiodostearates may persist for different times in the body and
the Panel further noted that corresponding data were missing. It had to be considered that variations in
composition of EEIFAPSO, which may be due to the use of poppy seed oils of different origin in the
manufacturing process, could lead to differences in the rate of release of iodine.

No data were available on short-term, subchronic and chronic toxicity, carcinogenicity and
reproductive toxicity of EEIFAPSO.

Overall the Panel could not conclude on the safety of EEIFAPSO as a source of iodine for the
fortification of food and on the bioavailability of iodine from this source due to data gaps in the kinetic
and the dynamic properties of the different iodinated compounds in EEIFAPSO.

EVALUATION

1.       Introduction
Following a request from the European Commission to the European Food Safety Authority (EFSA),
the Panel on Food Additives and Nutrient Sources added to Food (ANS), was asked to deliver a
scientific opinion on the safety of “iodized ethyl esters of poppy seed oil” (ethyl esters of iodinated
fatty acids of poppy seed oil, EEIFAPSO) and on the bioavailability of the iodine from this source when
used for the fortification of vegetable oils with iodine. The safety of iodine itself, in terms of amounts
that may be consumed, is outside the remit of this Panel.

2.       Assessment
EEIFAPSO are described as a mixture of ethyl palmitate (4.6-6.7 %), ethyl stearate (0.8-1.9 %), ethyl
monoiodostearates (11.3-15.3 %), ethyl diiodostearates (73.8-82.8 %), ethyl triiodostearates (< 0.6 %)
and as stabiliser poppy seed oil (1 %).

The source is intended to be added at the concentration of 2.76-3.05 mg of EEIFAPSO per kg of
vegetable oil. The iodine content of EEIFAPSO is 37-39 % (w/w). The final iodine content in the
iodine-enriched vegetable oils ranges from 1.021 to 1.190 mg /kg.

According to the applicant the aim is to use EEIFAPSO as a source of iodine to fortify vegetable oils.
An oil, containing 1 mg iodine/kg oil, was introduced on the market in Romania in 2006 where it is
used in addition to iodized salt. The Panel noted that oils fortified with EEIFAPSO are intended for long
term regular consumption by the general population.

EEIFAPSO have also been used as slow release preparations, orally administered once per year in
prophylactic campaigns for the prevention and control of iodine deficiency disorders (IDD), especially
in developing countries. Claude (1997) calculated the recommended oral single dosage to be
equivalent to 400-960 mg iodine (approximately 2-5 capsules, 1 capsule containing 190 mg iodine in
the form of 500 mg EEIFAPSO) in adults for 12 months of efficacy.

According to the applicant EEIFAPSO are obtained from poppy seed oil by complete iodination under
conditions, in which one iodine atom is added per double bond of the unsaturated fatty acid chains
(Wolff, 2001). The Panel noted that EEIFAPSO are a mixture containing a variety of up to 14 positional
isomers of the ethyl esters of mono-, di-, or triiodostearic acid, differing in the number of iodine atoms
and/or in the position of the iodine atom(s) in the fatty acid chain. In addition, due to the introduction
of one to three chiral centres by iodination, each of the 14 individual positional isomers exists in the
form of one to eight stereoisomers.

The Panel noted that the use of poppy seed oils of other botanical origins and/or geographical origins
as indicated by the applicant in the manufacturing procedure could result in different proportions of
ethyl monoiodostearates, ethyl diiodostearates and ethyl triiodostearates as described above due to
variation in the pattern of individual unsaturated fatty acids in the oils. An altered composition of the
iodinated components of EEIFAPSO might influence the persistence of iodine in the body, since
available data show that monoiodostearate esters or their metabolites have a higher retention in the rat
than diiodostearate esters or their metabolites (van der Heide et al., 1989).

Poppy seeds may be contaminated with alkaloids such as morphine, codeine, thebaine, noscapine,
papaverine and oripavine which could also contaminate poppy seed oil (EFSA Panel on Contaminants
in the Food Chain (CONTAM), 2011). Corresponding results of analysis for EEIFAPSO were made
available by the applicant upon request of the Panel. None of the aforementioned alkaloids could be
detected in EEIFAPSO. The limits of detection were 0.04, 0.02, 0.02, 0.75, 0.11 or 0.05 μg/g,
respectively. The analytical procedure was based on RP-HPLC (reversed phase High-performance
liquid chromatography) separation and subsequent ESI-MS (electrospray ionisation mass
spectrometry) detection (morphine, codeine, thebaine, noscapine and papaverine) or HPLC

EFSA Journal 2013;11(3):3120                                                                                    5
Iodized ethyl esters of poppy seed oil as a source of iodine added for nutritional purposes to
                                                                                                       foodstuffs

(oripavine). The Panel concluded that none of the alkaloids mentioned is considered to be associated
with a health risk for consumers with respect to the maximum levels given for EEIFAPSO taking into
consideration that the concentrations of EEIFAPSO in the fortified vegetable oils is limited to 2.76 to
3.05 mg/kg.

The Panel noted the absence of adequate data on the stability of EEIFAPSO and on the fate of EEIFAPSO
in vegetable oil during storage and processing of food.

Kinetic studies in humans with oral administration of EEIFAPSO in a single high dose followed by
observations for up to one year showed that iodine was retained in the body and progressively released
over a long time period (Ingenbleek et al., 2000; Leverge et al., 2003; Untoro et al., 2006). The Panel
noted that this was indicative of a long half life of EEIFAPSO or their metabolites.

The Panel noted that a new study investigating the kinetics in rat after a single dose of 125I labelled
EEIFApso and after a single dose of 125I labelled EEIFApso preceeded by 28 days dosing with unlabelled
EEIFApso resulted in greater absorption and altered kinetics of 125I labelled material after repeated
administration (TNO Triskelion, 2012).

The Panel also noted that rat data can only be used with caution in assessing the safety and kinetics of
EEIFAPSO due to species differences in iodine metabolism and the absence of thyroxine binding
globulin in adult rats (Hetzel and Maberly, 1986; IOM, 2001; Savu et al., 1992; SCF, 2002).

In a study in Romanian school children, who for a one-month-period received daily doses of oil
fortified with EEIFAPSO, elevated median urinary iodine excretion persisted in the 1st month following
the fortification period and returned to baseline values during the 3rd to 6th month (de Benoist et al.,
2009; Simescu et al., 2008). The Panel concluded that the slow clearance and altered kinetics after
repeated administration raises the question of potential bioaccumulation which cannot be ruled out
based on the current data.

The Panel noted that no data are available on short-term, sub-chronic and chronic toxicity,
carcinogenicity and reproductive toxicity of EEIFAPSO.

Mutagenicity testing with different strains of Salmonella typhimurium and Escherichia coli with and
without metabolic activation gave negative responses (Claude, 1997). In an in vitro chromosomal
aberration test with and without metabolic activation in human lymphocytes, negative results were
also obtained (Claude, 1997), but because of insufficient reporting, the Panel noted that the validity of
this assay could not be determined.

Pregnant rats (n=25 per group) received EEIFAPSO by gavage from day 6 to day 17 of gestation in
doses corresponding to 0, 50, 110 and 250 mg iodine/kg bw/day. The authors identified NOAELs for
EEIFAPSO corresponding to 110 mg iodine/kg bw/day (mid dose equivalent to 282-297 mg
EEIFAPSO/kg bw/day) for maternal toxicity and to 250 mg iodine/kg bw/day (highest dose equivalent
to 641-676 mg EEIFAPSO/kg bw/day) for developmental toxicity (Claude, 1997).

Furthermore EEIFAPSO were tested in two studies with continuous or intermittent administration by
gavage in pregnant rabbits (Claude, 1997). In the first study with continuous application from day 6 to
day 18 of gestation at levels of 12.5, 25 and 50 mg iodine in EEIFAPSO/kg bw/day, the maternal
tolerance of the treatment was poor. The number of early resorptions increased in all treatment groups.
Malformations in the fetuses were observed in the low and high dose groups. The Panel noted that
under these conditions of continuous treatment, the NOAEL has to be expected to be below the lowest
dose of EEIFAPSO tested, corresponding to 12.5 mg iodine/kg bw/day (equivalent to 32-34 mg
EEIFAPSO/kg bw/day). In the second study with intermittent application of EEIFAPSO corresponding to
12.5 mg iodine/kg bw/day (Group 1: dosing on gestation days 6, 9, 12, 15 and 18; Group 2: dosing on
gestation days 7, 10, 13 and 16; Group 3: dosing on gestation days 8, 11, 14 and 17), no maternal
toxicity was observed and no abnormalities were seen in the offspring. The Panel noted that the only

Iodized ethyl esters of poppy seed oil as a source of iodine added for nutritional purposes to
                                                                                                       foodstuffs

dose of EEIFAPSO which has been tested, corresponding to 12.5 mg iodine/kg bw/day (equivalent to
32-34 mg EEIFAPSO/kg bw/day), did not induce any adverse effect after intermittent treatment.

Overall the Panel noted the following:

        EEIFAPSO are a mixture containing potentially a variety of 14 positional isomers of the ethyl
        esters of mono-, di-, or triiodostearic acid, differing in their degree of iodine content and/or in
        the position of the iodine atom(s) in the fatty acid chain. Each of the 14 individual positional
        isomers exists in the form of two to eight stereoisomers.

        No data were provided on which of the positional isomers (and stereoisomers) occur in
        EEIFAPSO. The concentrations of the individual positional isomers (and stereoisomers) in
        EEIFAPSO are not known.

        There are no data on the stability of EEIFAPSO and on the fate of EEIFAPSO in vegetable oil
        during storage and/or processing of food.

        Kinetic data referring to conditions of fortification (low, repeated, oral, long-term exposure)
        are limited and available results indicate that a bioaccumulation of EEIFAPSO and/or their
        metabolites may occur.

        Data are inadequate for the quantitative assessment of the bioavailability of iodine from
        EEIFAPSO.

        On the basis of the available data, an adequate comparison of the bioavailability of iodine
        from EEIFApso to that from iodized salt (which is common for fortification purposes in food),
        or to that from other sources is not possible.

        The mechanism by which the different iodinated components of EEIFAPSO release iodine is
        not known.

        The break-down products or metabolites of EEIFAPSO have not been identified and it is also
        uncertain where deiodination of the components of EEIFAPSO occurs in the body.

        Monoiodostearic acid esters or their metabolites have a higher retention in the body than
        diiodostearic acid esters or their metabolites (no further characterisation of esters given) and
        will, thus, release iodide for longer periods (van der Heide et al, 1989). Thus the Panel
        presumed that different iodinated components in EEIFAPSO such as ethyl esters of mono-, di-
        and triiodostearic acid in the form of their various isomers may have different retention times
        in the body. Therefore a variation in composition of EEIFAPSO may lead to differences in the
        rate of release of iodine.

        It has to be taken into account that different manufacturers may produce EEIFAPSO from
        poppy seed oil of different botanical and/or geographical origins. Such oils may have different
        proportions of unsaturated fatty acids influencing the final proportions of ethyl esters of
        mono-, di-, or triiodostearic acid in EEIFAPSO.

        No adequate data on the residence time of iodine (retention time) in the body from ethyl
        monoiodostearate esters, ethyl diiodostearate esters and ethyl triiodostearate esters are
        available.

        There is a lack of data on possible differences in the kinetic and the dynamic properties of
        individual positional isomers (and stereoisomers) having the same molecular formula.

EFSA Journal 2013;11(3):3120                                                                                   7
Iodized ethyl esters of poppy seed oil as a source of iodine added for nutritional purposes to
                                                                                                        foodstuffs

        No data are available on short-term, sub-chronic and chronic toxicity, carcinogenicity and
        reproductive toxicity of EEIFAPSO.

        Negative results were obtained in mutagenicity tests with and without metabolic activation
        with Salmonella typhimurium strains and Escherichia coli and in human lymphocytes, but the
        validity of the latter assay could not be determined because the reporting of test conditions
        was inadequate.

        In developmental studies by gavage, in rats NOAELs for EEIFAPSO corresponding to 110 mg
        iodine/kg bw/day or 250 mg iodine/kg bw/day were identified for maternal toxicity or
        developmental toxicity, respectively. In rabbits receiving a daily administration of EEIFAPSO
        corresponding to 12.5 mg iodine/kg bw/day from day 6 to day 18 of gestation, maternal
        tolerance was poor and an increase in the numbers of early resorptions and malformations was
        induced.

As a whole the Panel considered the database to be inadequate for the evaluation of a mixture of
substances to be used for the fortification of food and therefore it could neither conclude on the safety
of EEIFAPSO as a source of iodine added for nutritional purposes to foodstuffs, nor on the
bioavailability of iodine from this source. This was due to gaps in knowledge on the composition of
EEIFAPSO and in the kinetic and dynamic properties of the different iodinated compounds being
present in EEIFAPSO.

CONCLUSIONS
The present opinion deals with the safety of EEIFAPSO as a source of iodine added for nutritional
purposes to foodstuffs and on the bioavailability of iodine from this source. The safety of iodine itself,
in terms of amounts that may be consumed, is outside the remit of this Panel.

In view of the inadequate data base the Panel cannot conclude on the safety of EEIFAPSO as a source
of iodine added for fortification purposes to foodstuffs, and on the bioavailability of iodine from this
source due to data gaps concerning the composition of EEIFAPSO and in the kinetic and the dynamic
properties of the different iodinated compounds being present in EEIFAPSO.
