Quality of western Canadian canola 2012
Free fatty acids content
The average free fatty acid content of the oil for the 2012 canola was 0.14%, slightly higher but still comparable to what was observed last year (0.12%) and comparable to what was observed in 2010 and 2009, 0.16% and 0.15%, respectively. This level is similar to the five-year average of 0.14%.
We have observed that free fatty acid content in canola can be high if temperatures are high during the growing season due to field heat stress. Average free fatty acid content levels in Canola, No. 1 Canada samples from Manitoba (0.18%) and Alberta (0.16%) were slightly higher than in Saskatchewan (0.11%). Free fatty acid content levels may change after harvest during storage if seeds are subjected to improper storage conditions
In November, the average free fatty acid content level for commercially clean Canola, No. 1 Canada exports was 0.31% (0.29% for the August to October exports). These averages were higher for the not commercially clean exports (0.35 and 0.37%). Last year’s average was 0.26%.
