Quality of western Canadian flaxseed 2011

Harvest survey samples

Flaxseed samples for the CGC harvest survey are collected and cleaned to remove dockage prior to testing. The samples are analyzed for oil, protein and iodine value using a NIRSystems 6500 scanning near-infrared spectrometer, calibrated to and verified against the appropriate reference method. Composite samples are used for free fatty acids and fatty acid composition analyses. Composites are prepared by combining Flaxseed samples by crop districts for each grade.

This year's harvest survey report includes 176 samples compared to 240 in 2010. Manitoba contributed 42 samples, Saskatchewan 115 samples and Alberta 16 samples during the harvest period from September 1 to December 1, 2011. Weighting factors are used to calculate provincial and western Canadian means.
