Foodstuffs - Determination of T-2 toxin and HT-2 toxin in cereals and cereal products for infants and young children by SPE clean up and HPLC-MS/MS
SIST EN 16923:2023

This document describes a method for the determination of T-2 toxin and HT-2 toxin in cereals and cereal-based products, e.g. oats, intended for nutrition of infants and young children by high performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS/MS) after cleanup by solid phase extraction (SPE) [5].
The method has been validated for HT-2 toxin in oat flour at levels of 9,3 µg/kg and 28,1 µg/kg, oat flakes at levels of 16,5 µg/kg and 21,4 µg/kg, and breakfast cereals (containing oat flakes) at a level of 8,1 µg/kg and for T-2 toxin in oat flour at levels of 4,4 µg/kg and 8,3 µg/kg, oat flakes at levels of 4,9 µg/kg and 6,6 µg/kg and breakfast cereals (containing oat flakes) at a level of 3,5 µg/kg.
Laboratory experiences [6] have shown that the method is also applicable to highly swelling materials (dry cereal-based porridges and modified starches), but these were not examined in the method validation study. Details are outlined in 7.3.
The method can also be applied to oat-by-products at higher levels of T-2- and HT-2 toxin. In this case, the dilution steps need to be considered [6].
The method can also be applied to cereals and cereal products for infants and young children based on e.g. wheat, barley and rice. In this case, the method needs to be in-house-validated for each material. At the time of the interlaboratory study, planned range was 10 µg/kg to 100 µg/kg, and it is known from the pre-study that the method works well in the whole range, although final validation was only done in the range from 3,5 µg/kg to 28,1 µg/kg.

Foodstuffs - Determination of ergot alkaloids in cereals and cereal products by dSPE clean-up and HPLC-MS/MS
SIST EN 17425:2021

This document describes a method for the determination of the sum of six ergot alkaloids (ergocornine, ergometrine, ergocristine, ergotamine, ergosine and ergocryptine) and their -inine epimer pairs by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) after clean-up by dispersive solid phase extraction (dSPE).
The method has been validated in the range 13,2 µg/kg to 168 µg/kg for the sum of the twelve ergot alkaloids, in rye flour, rye bread and cereal products (breakfast cereal, infant breakfast cereal, and crispbread) that contained rye as an ingredient, as well as seeded wholemeal flour and a barley and rye flour mixture.
Method performance was satisfactory in the range 24,1 µg/kg to 168 µg/kg, however at lower concentrations RSDR values were greater than 44 %, and HorRat values exceeded 2,0, indicating the method may not be fully suitable at concentrations below 24 µg/kg for sum of ergot alkaloids, although it is suitable for screening at these concentrations.

Foodstuffs - Determination of phomopsin A in lupin seeds and lupin derived products by HPLC-MS/MS
SIST EN 17252:2020

This document specifies a procedure for the determination of phomopsin A in lupin seeds and lupin-derived products based on liquid chromatography with tandem mass spectrometry (LC-MS/MS). Several phomopsins exist, i.e. phomopsin A, B, C and D, but the method only deals with the quantitative measurement of phomopsin A due to lack of commercially available analytical reference standards for the other phomopsins.
The method has been validated for phomopsin A in naturally contaminated lupin seeds, lupin flour and crisp bread at levels ranging from approximately 5 µg/kg to 60 µg/kg

Foodstuffs - Determination of zearalenone and trichothecenes including deoxynivalenol and its acetylated derivatives (3-acetyl-deoxynivalenol and 15-acetyl-deoxynivalenol), nivalenol T-2 toxin and HT-2 toxin in cereals and cereal products by LC-MS/MS
SIST EN 17280:2019

This document specifies a procedure for the determination of nivalenol (NIV), deoxynivalenol (DON) and its acetyl derivatives (3-acetyl-DON and 15-acetyl-DON), HT-2 and T-2 toxins (HT-2 and T-2) and zearalenone (ZEN) in cereals and cereal products by high performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS/MS) after clean-up by solid phase extraction (SPE).
The method has been validated with samples of wheat, wheat flour, and wheat crackers. The wheat and the wheat flour was prepared from a mixture of wheat and fungi infected wheat kernels. The wheat crackers were baked from wheat flour and water spiked with the target mycotoxins.
Validation levels for NIV ranged from 27,7 μg/kg to 378 μg/kg.
Validation levels for DON ranged from 234 μg/kg to 2420 μg/kg.
Validation levels for 3-acetyl-DON ranged from 18,5 μg/kg to 137 μg/kg.
Validation levels for 15-acetyl-DON ranged from 11,4 μg/kg to 142 μg/kg.
Validation levels for HT-2 ranged from 6,6 μg/kg to 134 μg/kg.
Validation levels for T-2 ranged from 2,1 μg/kg to 37,6 μg/kg.
Validation levels for ZEN ranged from 31,6 μg/kg to 230 μg/kg.
Laboratory experiences have shown that this method is also applicable to barley and oat flour, and rye based crackers [5], however, this has not been validated in a collaborative study.

Foodstuffs - Determination of acrylamide in food and coffee by gas chromatography-mass spectrometry (GC-MS)
SIST-TS CEN/TS 17083:2017

This Technical Specification specifies a method for the determination of acrylamide in cereal-based products, potato-based products and coffee by gas-chromatography mass spectrometry (GC-MS).
The method has been single-laboratory validated via the analysis of spiked samples (French fries (uncooked), bread, water biscuit, infant cereal, biscuit, green coffee, roast coffee and instant coffee), ranging from 30 μg/kg to 1 500 μg/kg acrylamide.
The results from the single laboratory validation were obtained by a laboratory with significant experience in acrylamide analysis. In addition, this method has also been studied by inter laboratory trial via the analysis of samples containing incurred acrylamide, ranging from approximately 200 μg/kg to 2 000 μg/kg. Critical points of the method are identified in 7.5 and Clause 8.

This draft European Standard describes a procedure for the determination of inorganic arsenic in foodstuffs of marine and plant origin by anion-exchange HPLC-ICP-MS following waterbath extraction.
This method has been validated in an interlaboratory test on white rice, wholemeal rice, leek, blue mussels, fish muscle and seaweed with an inorganic arsenic mass fraction in the range 0,073 mg/kg to 10,3 mg/kg [1].

Food analysis - Determination of acrylamide in food by liquid chromatography tandem mass spectrometry (LC-ESI-MS/MS)
SIST EN 16618:2015

This European Standard specifies a method for the determination of acrylamide in bakery ware such as bread, toasted bread, crisp bread, butter cookies, and biscuits, as well as potato products such as potato chips, potato crisps, and potato pan cake and roasted coffee, by liquid chromatography in combination with electrospray ionization and tandem mass spectrometry (LC-ESI-MS/MS). This method has been validated in an interlaboratory study via the analysis of both naturally contaminated and spiked samples, ranging from 14,3 µg/kg to 9 083 µg/kg. It was developed at the Swedish National Food Administration and validated in a study organized by the Directorate General Joint Research Centre (DG JRC), Swedish National Food Administration and the Nordic Committee on Food Analysis (NMKL), see [1] and [2].
The limit of quantification (LOQ) depends on the type of instrument used and on the actual performance of the instrument. The majority of the laboratories participating in the validation study were able to determine acrylamide in a butter cookie sample at a level of 14,3 µg/kg. Thus, the validation by interlaboratory study showed that LOQ can be expected to be in the range between below 15 µg/kg and 30 µg/kg.

SIST EN ISO 16050:2011

ISO 16050:2003 specifies a reverse-phase high-performance liquid chromatographic method, with immunoaffinity column clean-up and post-column derivatization, for the determination of aflatoxins in cereals, nuts and derived products. The limit of quantification for aflatoxin B1, and for the sum of aflatoxins B1, B2, G1 and G2, is 8 micrograms per kilogram.
The method has been validated for maize containing 24,5 micrograms per kilogram, for peanut butter containing 8,4 micrograms per kilogram, and for raw peanuts containing 16 micrograms per kilogram of total aflatoxins. It has also been shown that this method can be used for oilseed products, dried fruits and derived products.
