Quality of western Canadian flaxseed 2013
Harvest survey samples
Flaxseed samples for the Canadian Grain Commission’s 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 No. 1 flaxseed samples by province. Composites of Flaxseed No. 2 Canada Western, No. 3 Canada Western and Sample Grade combine all samples from western Canada by grade.
This year's harvest survey report includes 176 samples compared to 239 in 2012. Manitoba contributed 34 samples of No. 1 flaxseed, Saskatchewan contributed 123 samples, and Alberta 13 samples during the harvest period from September 1 to December 1st, 2013. Weighting factors are used to calculate provincial and western Canadian means.
