BS EN 17252:2020 pdf can be downloaded here,whose title is Foodstuffs—Determination of phomopsin A in lupin seeds and lupin derived products by HPLC-MS/MS.
Phomopsins are mycotoxins produced by the fungus Diaporthe toxica. There are several phomopsis of which phomopsin A is the major toxic congener. The main host of the fungus are lupins ( Lupinus L). Lupin seeds are being used as food ingredients and therefore phomopsin A might occur in food ingredients and food products containing lupin seeds or lupin flour.
BS EN 17252:2020 specifies a procedure for the determination of phomopsin A in lupin seeds and lupin-derived products based on liquid chromatography with tandem mass spectrometry.Several phomopsis 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 phomopsis.
Details of the interlaboratory test of the precision of the method are summarized in Annex A. The values derived from the interlaboratory test may not be applicable to analyte concentration ranges and matrices other than given in Annex A.
