Quality of western Canadian canola 2014
Harvest Sample Program samples and grade distribution
This report of quality data for the 2014 harvest is based on analyses of 1,993 individual canola samples. Composites of various grades from various crop districts composites from each province were made using 1,955 samples. Specialty oil samples, such as high oleic acid, low linolenic acid, and high erucic acid, were excluded from this report. More canola samples were received in 2014 than in 2013 (1,676); however, this is less than what was received in 2012 (2,108).
Exports of commercially cleaned canola exports (from August 2014 to November 2014) contained on average 1.70% dockage, ranging from 0.77 to 2.30%, which affects quality factors such as oil content, chlorophyll and free fatty acid. Canola exports containing over 2.5% dockage are considered not commercially clean (NCC) and have even greater reductions in measured quality components. The composition of 2014 samples was compared to 2013 results and to long-term sample program means.
81.4% of samples were graded Canola, No. 1 Canada, compared to 93.7% in the 2013 harvest and 82.0% in 2012. This number (81.4%) is much lower than the 5-year average of percentage of Canola, No. 1 Canada (85.6%).
The grade distribution of the 2014 canola crop varied from crop district to crop district. In some areas, the percentage of samples graded Canola, No. 1 Canada was lower than 70%. Manitoba had the highest percentage of samples graded Canola, No. 1 Canada (88.7%), followed by Saskatchewan (81.4%). The lowest percentage of samples graded Canola, No. 1 Canada were from Alberta crop districts 6 and 7 at 59.6% and 77.7% respectively.
The main degrading factor for Canola, No. 1 to Canola, No. 3 was high distinctly green seed counts. Distinctly green seed counts (DGR) were 0.59% in Canola, No. 1 Canada, 3.28% in Canola, No. 2 Canada, 9.68% in Canola, No. 3 Canada and 6.28% in Sample. Most of samples at the lowest grade (Sample) were downgraded because of admixture and sprouting but not because of destinctly green seed counts. The Official Grain Grading Guide defines conspicuous admixture as material found in the sample after cleaning and is easily distinguished from canola without the use of magnification.
