Quality of western Canadian canola 2013

Comparisons to export shipment data

Tables 3 to 5 show detailed information on the quality of western Canadian canola harvested in 2013, whereas Table 6 compares the quality of the 2013 harvest to the quality of recent canola exports. It is important to note that the number of samples in each grade or province may not be representative of the total production or grade distribution. However, there were sufficient samples to provide good quality information for each province and each grade. Provincial and western Canadian means were calculated from results for each crop district weighted by the averages of 2010-12 total production (Statistic Canada) and the estimate of grade distribution from crop reports (Figure 5).

All oil and protein content values discussed below are presented using the Canadian Grain Commission’s historical 8.5% moisture basis in order to permit annual and regional comparisons.

Exports of commercially cleaned canola contained up to 2.5% dockage, which will affect quality factors such as oil content, chlorophyll and free fatty acids. Canola exports containing over 2.5% dockage are considered not commercially clean and will have even greater reductions in measured quality components.
