The use of rapeseed cake is limited by the presence of a number of antinutritional factors the most important of which are glucosinolates. Introduction by EEC of a premium to produce rapeseed with low glucosinolate content has brought the need for reference material and accurate official methods of analysis. This paper summarises the work, begun at the end of 1987, to prepare three batches rapeseed materials (cleaning, mixing and packaging) for an intercomparison of methods. Details are presented of homogeneity and stability studies and the results of the intercomparison are discussed. One of the batches was prepared in sufficient quantity to serve as a reference material and the reference value for the total glucosinolate content of this sample was obtained from the results of the intercomparison
