Coffee and coffee products — Determination of acrylamide — Methods using high-performance liquid chromatography with mass spectrometric detection (HPLC-MS/MS) and gas chromatography with mass spectrometric detection (GC-MS) after derivatization

ISO 18862:2016 specifies methods for the determination of acrylamide in coffee and coffee products by extraction with water, clean-up by solid-phase extraction and determination by HPLC-MS/MS and GC-MS. It was validated in a method validation study on roasted coffee, soluble coffee, coffee substitutes and coffee products with ranges from 53 μg/kg to 612,1 μg/kg.

Coffee and coffee products — Determination of acrylamide —

WARNING — The use of this document can involve hazardous materials, operations and equipment.
This document does not purport to address all the safety problems associated with its use. It is the
responsibility of the user of this document to take appropriate measures for ensuring the safety and
health of the personnel prior to application of this document and to fulfil statutory requirements for

1 Scope
This document specifies methods for the determination of acrylamide in coffee and coffee products by
extraction with water, clean-up by solid-phase extraction and determination by high-performance liquid
chromatography with mass spectrometric detection (HPLC-MS/MS) and gas chromatography with mass
spectrometric detection (GC-MS). It was validated in a method validation study on roasted coffee, soluble
coffee, coffee substitutes and coffee products with ranges from 53 μg/kg to 612,1 μg/kg.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes
requirements of this document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
ISO 3696, Water for analytical laboratory use — Specification and test methods
3 Terms and definitions
No terms and definitions are listed in this document.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
4 Principle
The coffee sample is extracted with water or, in the case of soluble products, dissolved in water. A clean-up by
solid phase extraction (SPE) is employed to remove interfering matrix compounds. Two alternative methods
can be used for the determination: HPLC-MS/MS or, after a bromination of the acrylamide, GC-MS. In both
cases, isotopic labelled internal standard solutions are used.
5 Reagents
WARNING — In view of health risks when working with acrylamide, appropriate preventive and
protection measures shall be taken, such as using a fume cupboard, aspirating acrylamide-containing
solutions only with a pipette, and avoiding skin and eye contact or inhalation of acrylamide-containing
vapour.
If available, reagents of “residue analysis grade” or “analytical reagent grade” shall be used. The level of
impurities in the reagents that contribute to the blank should be negligibly small. The blank shall be checked
regularly.
For HPLC-MS/MS, the solutions according to 5.4.1 to 5.5.2 can be prepared using the HPLC eluent as a solvent.
The stability of these solutions depends on the mobile phase used and shall be validated.
When using GC-MS, all standard solutions according to 5.4.2 and 5.5.2 shall be subjected to the derivatization
step according to 8.5.1.
Instead of D3-acrylamide, it is also possible to use C acrylamide for the preparation of the internal standard
solution. However, in Clauses 8clause 8 and 9 clause 9, the procedure and calculation are described for D3-
acrylamide only.
5.1 Water, of grade 1 according to ISO 3696
5.2 Operating gases of high purity, suitable for gas chromatography and mass spectrometry according to
the instructions of the manufacturer of the apparatus.
5.3 Solvents, such as methanol, ethyl acetate, acetonitrile and n-hexane. MS-grade.
5.4 Acrylamide, C H NO, purity > 98 %, reference substance.
3 5
5.4.1 Acrylamide stock solution, mass concentration ρ = 1 000 μg/ml.
Weigh (0,10 ± 0,001) g of acrylamide into a 100 ml one-mark volumetric flask and swirl it in 30 ml of water in
order to dissolve the acrylamide. Fill up to the mark with water and mix well. The stock solution is stable for
at least three months when stored protected from light at a maximum of 6 °C.
Alternatively, a commercially available solution with a mass concentration of ρ = 1 000 µg/ml may be used.
The information of the manufacturer regarding the stability of the solution shall be observed.
5.4.2 Acrylamide calibration solution, ρ = 10 μg/ml.
Using a pipette, transfer (1,0 ± 0,001) ml of the acrylamide stock solution (5.4.1) into a 100 ml one-mark
volumetric flask and fill up to the mark with water. This solution shall be stored protected from light at a
maximum of 6 °C and shall be freshly prepared every working day. Depending on the working range, more
dilution steps can be necessary.
