This document specifies a rapid method for extraction of oil and for preparation of the methyl esters of fatty acids. The methyl esters thus obtained can be used for gas chromatography. This International Standard is applicable to the following oilseeds: rape, sunflower, soya beans, mustard, linseed. NOTE Applying this rapid method to high erucic acid content rapeseed leads to an overestimation of erucic acid.

Rapeseed and rapeseed meals - Determination of glucosinolates content - Method using high-performance liquid chromatography (ISO 9167:2019)
EN ISO 9167:2019

This document specifies a method for the determination of the individual glucosinolates content in
rapeseeds and rapeseed meals using high-performance liquid chromatography with gradient elution.
This method was tested on rapeseeds and rapeseed meals (Brassica rapa, Brassica napus and Brassica
juncea) but is applicable to other plant materials, on the condition that the occurring glucosinolates
previously identified are described in this document. On the contrary, the quantitative analysis of the
concerned glucosinolate(s) is not carried out.
NOTE This method does not determine glucosinolates that are substituted on the glucose molecule, but
these compounds are of little importance in commercial rapeseed and rapeseed meal.
Annex A presents the results of the interlaboratory trials for the gradient elution HPLC method.
Annex B presents how to check the titre of the prepared internal standard solution. Annex C presents
how to prepare and test the purified sulfatase solution and how to check the desulphation step on the
ion exchange column. Annex D presents the HPLC and column performance criteria qualification.
The analysis of glucosinolates content in rapeseed can also be done using an isocratic elution mode.
This requires some modifications of the method (internal, standard, HPLC column and HPLC buffers),
as described in Annex E.

corresponding extraction meals, pellets and expeller cakes.
It is not applicable to disputed cases, for which ISO 734 is applicable.
It is applicable to oilseed meals obtained from oilseeds by expelling or by extraction with a solvent, as
well as to the pellets made from the residues.

Oilseeds - Determination of oil content (Reference method) (ISO 659:2009)
EN ISO 659:2009

This International Standard specifies a reference method for the determination of the hexane extract (or light petroleum extract), called "oil content", of oilseeds used as industrial raw materials. The procedure for sunflower seeds is different from the other seeds as it includes a second moisture content determination after the first mechanical grind. The method has been tested on rapeseed, soya beans and sunflower seeds. This does not, however, preclude its applicability to other commercial seeds. If required, the pure seeds and the impurities (see 9.4) may be analysed separately. In the case of groundnuts, the pure seeds, the total fines, the non-oleaginous impurities and the oleaginous impurities (see 10.1.6) may be analysed separately.

This part of ISO 16634 specifies a method for the determinatio n of the total nitrogen content and the calculation of crude p rotein content of oilseeds and animal feeding stuffs. This met hod, like the Kjeldahl method, does not distinguish between pr otein nitrogen and non-protein nitrogen. For the calculation o f protein content, various conversion factors are used (see An nex D).
