This part of ISO 9167 specifies a method for the determination of the content of the different glucosinolates in rapeseeds (colza) using high-performance liquid chromatography.
NOTE 1 This method does not determine glucosinolates which are substituted on the glucose molecule, but these compounds are of little importance in commercial rapeseed.
NOTE 2 A rapid method for the determination of glucosinolatescontent using X-ray fluorescence spectrometry is the subject of ISO 9167-2.
