Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 15302 was prepared by Technical Committee
ISO/TC 34, Agricultural food products, Subcommittee SC 11, Animal and
vegetable fats and oils.
Annexes A and B of this International Standard are for information only.

Animal and vegetable fats and oils — Determination of
benzo[a]pyrene content — Reverse-phase high-performance liquid
chromatography method
1 Scope
This International Standard specifies a method for the determination of benzo[a]pyrene in crude or refined edible
oils and fats by reverse-phase high-performance liquid chromatography (HPLC) using fluorimetric detection in the
range from 0,1 μg/kg to 10 μg/kg.
2 Normative reference
The following standard contains provisions, which through reference in this text, constitute provisions of this
International Standard. At the time of publication the edition indicated was valid. All standards are subject to revision
and parties to agreements based on this International Standard are encouraged to investigate the possibility of
applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of
currently valid International Standards.
ISO 661:1989, Animal and vegetable fats and oils — Preparation of test sample
3 Principle
Adsorption of a suitable amount of sample on an alumina column, followed by elution with light petroleum of any
benzo[a]pyrene present, and subsequent analysis of the eluate by HPLC using a fluorimetric detector.
4 Reagents
All reagents shall be of recognized analytical grade. Where analytical grade solvents other than the recommended
ones are used, a full blank analysis shall be carried out and the results of this blank analysis reported.
4.1 Water, double distilled, filtered through a membrane filter of 0,45 μm pore size; deionized water obtained by
purifying demineralized water systems may also be used.
4.2 Light petroleum (boiling point range between 40 °C and 60 °C), or hexane, redistilled over potassium
hydroxide pellets (4 g/l).
4.3 Acetonitrile, suitable for HPLC.
4.4 Tetrahydrofuran, suitable for HPLC.
4.5 Toluene, suitable for HPLC.
4.6 Sodium sulfate, granular, anhydrous.

4.7 Alumina, activity grade 4, prepared from neutral aluminium oxide, activity grade super 1, deactivated by the
addition of 10 ml distilled water to 90 g of alumina.
CAUTION — THE REACTION IS EXOTHERMIC AND PRESSURE MAY BUILD UP.
Shake the container for about 15 min and allow the contents to equilibriate for 24 h. Store the alumina in a closed
vessel at ambient temperature.
4.8 Benzo[a]pyrene, 99,0 % purity.
CAUTION — BENZO[a]PYRENE IS A KNOWN CARCINOGEN. CARRY OUT ALL WORK WITH IT IN A FUME
HOOD, WEARING GLOVES TO MINIMIZE EXPOSURE.
1)
4.9 Benzo[a]pyrene solutions
4.9.1 Stock solution
Weigh, to the nearest 0,1 mg, about 12,5 mg of benzo[a]pyrene in a 25 ml graduated flask. Dissolve it in toluene
(4.5) and fill to the mark.
This solution contains about 0,5 mg/ml benzo[a]pyrene and should be stored in the dark at 4 °C when it is stable for
6 months at least.
4.9.2 Standard solutions
Prepare two standard solutions containing approximately 0,2 μg/ml and 0,01 μg/ml of benzo[a]pyrene respectively
by diluting aliquots of the stock solution (4.9.1) with acetonitrile (4.3).
5 Apparatus
Usual laboratory apparatus and, in particular, the following.
5.1 Glass column for chromatography, 300 mm long, 15 mm internal diameter, fitted with sintered glass discs,
and polytetrafluoroethylene (PTFE) tap.
5.2 Water baths (two), maintained at 35 °C – 1°C and 65 °C – 1°C.
5.3 Flash evaporator
A rotary evaporator with vacuum and a water bath set at 40 °C may be used. Care should be taken to prevent cross
contamination. Clean the system thoroughly between determinations.
5.4 High-performance liquid chromatograph, consisting of an HPLC pump, injection valve with 10 μl sample
loop, reverse-phase column, electronic integrator and chart recorder.
NOTE If an autosampler is used, the sample loop should be flushed with acetonitrile between subsequent injections.
