Quality of western Canadian flaxseed 2012
Harvest survey samples
Flaxseed samples for the Canadian Grain Commission 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 province for Flaxseed, No. 1 CW and Flaxseed No. 2 CW, No. 3 CW Canada and Sample Grade by western Canada.
This year's harvest survey report includes 239 samples compared to 176 in 2011. Manitoba contributed 54 samples, Saskatchewan 165 samples and Alberta 12 samples during the harvest period from September 1 to December 1st, 2012 of Flaxseed, No. 1 CW. Weighting factors are used to calculate provincial and western Canadian means.
