ISO 9167-2:1994 PDF

Scope: This part of ISO 9167 specifies a rapid method for the determination of the total glucosinolate content of rapeseed using X-ray fluorescence spectrometry (XRF). lt is applicable to seeds with a normal Protein content from 19 % to 23 %. For seeds with a Protein content outside this range, account should be taken of the total Protein content in the calculation of the total glucosinolate content (see reference [4]). NOTES 1 ISO 9167-1 specifies a method using high-performance liquid chromatography (HPLC) which enables the content of different glucosinolates to be determined individually. 2 When applied to immature seed or to seed that has been badly stored, for example under damp and warm conditions, the results obtained by the XRF method and by the HPLC method (ISO 9167-1) may not agree as closely as when applied to normal rapeseed. The HPLC method should be taken as the reference method.
