After harvest, the grains were dried to 13%±1% of moisture at a
grain mass temperature below 40 °C. For each ecotype and cultivar,
the starting material was around 10,000 g. These samples were divided
in 1000 g samples for the various processing conditions, resulting
in samples of around 800 g after each processing. These samples
were further subdivided in samples of 200 g used for the laboratory
analyses.
