Quality of western Canadian canola 2015
This report presents quality data and information based on the Canadian Grain Commission’s 2015 harvest sample program of 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 maps (Figure 1) shows traditional growing areas for canola in western Canada with 2013 and 2014 production data per crop district.

The 2015 harvest showed a higher percentage of samples graded Canola, No. 1 Canada (91.5%) than the 2014 harvest (80.8%), this number was higher than the 10 year average (87.1%) (Figure 4). Large variations in grade distribution were observed. Alberta-Peace River area showed the lowest percent of samples graded Canola, No. 1 Canada (86.6%) when compare to Manitoba (93.6%) and Saskatchewan (93.8%) (Figure 5). The crop district 7 of Alberta and the Peace River area of British Columbia showed the lowest percent of samples graded Canola, No. 1 Canada (65.8%).
The 2015 western Canadian canola (Canola, No. 1 Canada) crop was characterized by similar oil content (44.2%) and a slight increase in protein (20.7% versus 20.2%) when compared to the 2014 Canola, No. 1 Canada crop (Table 1). Average chlorophyll content was similar in 2015 when compared to 2014 (12 milligrams per kilogram versus 13 milligrams per kilogram, respectively) (Table 1) with some areas showing averages higher than 15 milligrams per kilogram (Table 3). Samples from Manitoba and Saskatchewan showed similar chlorophyll content averages whereas Alberta-Peace River showed a higher average: 11 milligrams per kilogram for both Manitoba and Saskatchewan versus 14 milligrams per kilogram for Alberta-Peace River.
The 2015 canola crop had a slightly different oleic acid content, linoleic acid and α-linolenic acid contents when compared to the 2014 crop (62.6, 18.8 and 9.7% versus 63.2, 18.7 and 9.2% for oleic, linoleic acid, and α-linolenic acid respectively). Total saturated fatty acid content was identical to what was observed in 2014 (6.7 %). This resulted in a slightly higher iodine value in the 2015 canola crop when compared to 2014 canola crop (113.1 versus 112.2 units in 2014). Mean free fatty acids average levels in 2015 Canola, No. 1 Canada seed was identical to what was observed in 2014 (0.18%) (Table 1), however in Manitoba, some crop district averages were much higher than the Western Canadian average (Table 4).
