Quality of western Canadian flaxseed 2015
Flaxseed samples for the Canadian Grain Commission’s Harvest Sample Program are collected and cleaned to remove dockage prior to testing. The samples are analyzed for oil, protein and iodine value using a Foss NIR Systems 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 samples by province for Flaxseed, No. 1 Canada Western. Composites of Flaxseed,No. 2 Canada Western, Flaxseed, No. 3 Canada Western and Sample Grade combine all samples from western Canada by grade.
This year's harvest report includes 296 samples compared to 259 in 2014. Manitoba contributed 37 samples of Flaxseed, No. 1 Canada Western, Saskatchewan 215 samples, and Alberta 39 samples during the harvest period from September 1 to December 1, 2015. There were 5 samples that were graded as Flaxseed, No. 2 Canada Western and Sample Grade. Weighting factors are used to calculate provincial and western Canadian means.
