    Abstract - (Show below) - (Hide below)

    Defines a rapid method for determining the oil and moisture contents of commercial oilseeds, by means of a pulsed nuclear magnetic resonance (NMR) spectrometer. The method has been tested on rapeseed, and applies to rapeseed having a moisture content under 10%. Seeds with a higher moisture content must be dried before determining the oil content by pulsed NMR.

    Scope - (Show below) - (Hide below)

    This International Standard specifies a rapid method for the determination of the oil and water contents of commercial oilseeds using pulsed nuclear magnetic resonance (NMR).

    It is applicable to rapeseeds, soya beans, linseeds and sunflower seeds with a water content less than 10%. For seeds with higher water contents, drying is necessary before the oil content can be determined by pulsed NMR.

    NOTE1 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.

    NOTE2 The reproducibility values are generally higher than those obtained by the drying method (ISO665).
