Oilseeds - Simultaneous determination of oil and water contents - Method using pulsed nuclear magnetic resonance spectrometry (ISO/FDIS 10565:2026); German and English version FprEN ISO 10565:2026
Abstract
This document specifies a rapid method for the determination of the oil and water contents in oilseeds using pulsed nuclear magnetic resonance (NMR). It is applicable to rapeseeds, linseeds and sunflower seeds with a water content less than 10 %, and soya beans with a water content less than 14 %. For seeds with higher water contents, drying is necessary before the water and oil content can be determined by pulsed NMR. NOTE 1 This method has been tested with rapeseeds, soya beans, linseeds and sunflower seeds. This does not, however, preclude its applicability to other commercial seeds whose oil is liquid at the temperature of measurement. NOTE 2 The reproducibility values obtained are generally higher than those obtained by the reference methods (ISO 659 and ISO 665) because they depend on the variability between the instruments and on that existing between the calibrations, which depends on the measurement accuracy of the reference methods. NOTE 3 The results of comparison test carrying out from different magnets and different volumes of seed samples (Annex B) are in coherence with results of interlaboratory test (Annex A). It's concluding that this method is applicable on different magnets NMR.
