Quality of western Canadian mustard 2014

Harvest samples

This year's Harvest Sample Program included 387 samples, compared to 308 in 2013. This included 221 yellow, 98 brown and 68 oriental mustard samples. Overall, 71.6% of the samples came from Saskatchewan, followed by 27.4% from Alberta and 1.0% from Manitoba.

Producers, grain companies and elevators that routinely handle mustard seed submitted samples of mustard grown in 2014 to the Canadian Grain Commission. The individual samples were cleaned to remove dockage and were graded by Canadian Grain Commission inspectors, following Chapter 12 of the Official Grain Grading Guide.

Oil, protein, and glucosinolate content was determined on all individual whole-seed samples using a FOSS NIRSystems 6500 scanning near infra-red spectrometer, which was calibrated to and verified against the appropriate listed reference methods. The reference procedures are listed under Oilseeds Methods.

Composite samples were analysed for oil, protein, glucosinolate and chlorophyll content, as well as for fatty acid composition. Composites were prepared by combining No. 1 mustard samples by province and type and by combining No. 2, No. 3, No. 4 and Sample grades by western Canada and by type. Composites were also prepared for the most common mustard varieties.
