Quality of western Canadian flaxseed 2016 - Introduction


This report presents quality data and information based on samples of western Canadian flaxseed from the Canadian Grain Commission’s 2016 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 map shows the Prairie provinces, the traditional growing areas for flaxseed in western Canada.

The Canadian Grain Commission’s Harvest Sample Program of western Canadian flaxseed shows that the 2016 crop contains similar oil content, higher protein content and slightly lower iodine values when compared to the 2016 harvest.

Table 1 shows data for Flaxseed, No. 1 Canada Western. Oil content is 45.6%, which is similar to the 2015 mean (45.7%) and the same as the 10-year mean (45.6%). Protein content is 21.9% and is lower than the 2015 mean (22.5%) and the 10-year mean (22.3%). Iodine value is 192.2 units, which is 0.7 units higher than the 2015 value of 191.5 units.

Environmental factors can play an important role in oil and protein content trends, as well as fatty acid composition. The Grain Research Laboratory’s long-term harvest sample results have shown cool, wet growing conditions tend to produce a flaxseed crop with higher oil content and iodine values and lower protein content.
