This report presents quality data and information based on samples of western Canadian flaxseed from the Canadian Grain Commission’s 2018 Harvest Sample Program. The quality data includes oil, protein, free fatty acids, fatty acid composition and iodine values of harvest samples submitted to the Grain Research Laboratory. Producers and grain companies submitted the samples throughout the harvest period. The Prairie provinces map shows traditional growing areas for flaxseed in western Canada.
The Canadian Grain Commission’s Harvest Sample Program of western Canadian flaxseed shows that the 2018 crop contains lower oil content, similar protein content and lower iodine values when compared to the 2017 harvest.
