Quality of western Canadian canola 2012

Protein content

The 2012 crude protein content mean was 21.3, 21.8, 21.4 and 21.8% for Canola, No. 1 Canada, Canola, No. 2 Canada, and Canola, No. 3 Canada and Samples, respectively.  The average protein content for Canola, No. 1 Canada was higher in 2012 (21.3%) than in 2011 (19.6%) and much higher than the five year averages (20.4%).  This 2012 crude protein content mean was similar to the ten year average (21.2%).  Protein content averages were 23.0, 20.9 and 21.0% in Manitoba, Saskatchewan and Alberta, respectively with protein content of individual producer samples ranging from 15.9 to 28.5% for Canola, No. 1 Canada samples and from 16.7 to 26.1% for Canola, No. 2 Canada samples.

The 2012 protein content calculated to an oil-free meal at 8.5% moisture basis was 40.6%, which was significantly higher than what was observed in 2011 (38.8%) and well above the 39.6 calculated for the five-year average. This 2012 average was identical to the ten-year calculated average (40.6%).  The calculated protein content of the oil-free meal (100% defatted) was much higher in Manitoba (42.2%) than in Alberta (40.3%) or Saskatchewan (40.1%).

In canola, it is known that oil and protein contents follow an inverse relationship – the lower the oil, the higher the protein content.  Since lower oil contents were observed in 2012 compared to 2011, higher protein contents were expected in the 2012 canola harvest when compared to the 2011 averages.

The mean oil protein of Canola, No. 1 Canada commercially clean exports were 21.1 and 20.7% in November 2012 and August-to-October 2012, respectively.  The protein content averages for the actual shipping season were higher than what was observed for last shipping season (19.6% for Aug 2011 to July 2012). The higher export protein means reflected the higher protein content average observed in the 2012 harvest when compared to the 2011 harvest.

The average calculated protein content of the meal was 39.9% for the November 2012 commercially clean exports of Canola, No. 1 Canada, this result is about 2% higher than was was observed during last shipping season (averaged 38.1% for commercially clean exports of Canola, No. 1 from August 2011 to July 2012).

It is expected that the protein content of the Canadian exports will remain in the 21.0% range for most of the 2012-13 shipping season.
