Quality of western Canadian canola 2014
Free fatty acids content
The average free fatty acids content of the oil for the 2014 canola was 0.18%, comparable to what was observed in 2013 (0.13%). This level is also similar to the 5-year average of 0.13%.
Average free fatty acids levels in Canola, No. 1 Canada samples from Manitoba (0.23%) and Alberta-Peace River (0.23%) were slightly higher than in Saskatchewan (0.13%).
We have observed that free fatty acids in canola can be high due to field heat stress, if temperatures are high during the growing season or, if there is a lot of rain at harvest that could lead to sprouting or high moisture harvested canola. There was a killer frost with snow in Alberta-Peace River on September 11, 2014. Severe precipitations with ponding also happened in Manitoba and Saskatchewan during the September long weekend followed by intermittent precipitation during the first 2 weeks of September. This excess of moisture could further lead to an increase in free fatty acids content of seed later during the shipping season if seeds are subjected to improper storage conditions.
In November, average free fatty acids level for commercially clean Canola, No. 1 Canada exports was 0.32% (0.29% for the 2014 August to October exports). These averages are similar to not commercially clean exports (0.22% for the 2013 August to October exports). Last year’s average (0.28%) was also similar. Some weather related damages (e.g. sprouting and water damage), were observed in 2014 canola samples, this could lead to an increase in FFA during the 2014-15 shipping season.
