Quality of western Canadian canola 2014
This report presents quality data and information based on the Canadian Grain Commission’s 2014 Harvest Sample Program for western Canadian canola. Quality parameters included are oil, protein, chlorophyll, glucosinolates, free fatty acids and the fatty acid composition of harvest samples. Quality data are from analyses of canola samples submitted to the Canadian Grain Commission throughout the harvest period by producers, grain companies and oilseed crushing companies.
The 2014 harvest showed a lower percentage of samples graded Canola, No. 1 Canada (81.4%), a much lower percentage than the 2013 harvest (93.7%). In fact, this was the lowest percentage of samples graded as Canola, No. 1 Canada since 2010. Variations in grade distribution were observed: in some areas of Alberta-Peace River and Saskatchewan less than 65% of the samples graded Canola, No. 1 Canada.
The 2014 western Canadian canola (Canola, No.1 Canada) crop was characterized by a decrease in oil (44.2% versus 44.8%) and a slight increase in protein (20.2% versus 19.7%) when compared to the 2013 Canola, No. 1 Canada crop. Average chlorophyll content was higher in 2014 than in 2013 (13 mg/kg versus 12 mg/kg, respectively). However chlorophyll content distribution varied greatly by location. Samples from Manitoba had a much lower chlorophyll average than Saskatchewan or Alberta-Peace River: 10 mg/kg for Manitoba versus 14 mg/kg for Saskatchewan and Alberta-Peace River. The 2014 canola crop had similar oleic acid content, linoleic acid and α-linolenic acid contents when compared to the 2013 crop (63.2, 18.7 and 9.2% versus 63.4, 18.5 and 9.1 % for oleic, linoleic acid, and α-linolenic acid respectively). Total saturated fatty acid content was similar to what was observed in 2013 (6.7 in 2014 versus 6.8% in 2013). This resulted in a slightly higher iodine value in the 2014 canola crop when compared to 2013 canola crop (112.2 versus 111.7 units in 2013). Mean free fatty acids levels in 2014 Canola, No. 1 Canada seed was similar to what was observed in 2013 (0.18 versus 0.13%).
