BS EN 17280:2019

This standard BS EN 17280:2019 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 is classified in these ICS categories:

• 67.060 Cereals, pulses and derived products

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 were 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 ?g/kg to 378 ?g/kg.

Validation levels for DON ranged from 234 ?g/kg to 2420 ?g/kg.

Validation levels for 3-acetyl-DON ranged from 18,5 ?g/kg to 137 ?g/kg.

Validation levels for 15-acetyl-DON ranged from 11,4 ?g/kg to 142 ?g/kg.

Validation levels for HT-2 ranged from 6,6 ?g/kg to 134 ?g/kg.

Validation levels for T-2 ranged from 2,1 ?g/kg to 37,6 ?g/kg.

Validation levels for ZEN ranged from 31,6 ?g/kg to 230 ?g/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.
