This document defines a routine method for the determination of moisture and protein contents in whole kernels of wheat and barley using near infrared spectroscopy in the constituent ranges:<\/p>\n

    \n
  1. \n

    for wheat:<\/p>\n

      \n
    1. \n

      moisture content minimum range from 8 % to 22 %;<\/p>\n<\/li>\n

    2. \n

      protein content minimum range from 7 %DM to 20 %DM.<\/p>\n<\/li>\n<\/ol>\n<\/li>\n

    3. \n

      for barley:<\/p>\n

        \n
      1. \n

        moisture content minimum range from 8 % to 22 %;<\/p>\n<\/li>\n

      2. \n

        protein content minimum range from 7 %DM to 16 %DM.<\/p>\n<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

        This document describes the modalities to be implemented by the supplier (5.3<\/span> and 5.4<\/span>) and the user of the method.<\/p>\n
