Quality of western Canadian canola 2012

Quality of western Canadian canola 2012

It is important to note that the numbers of samples in each grade or province may not be representative of the total production or grade distribution.  However, there were sufficient samples to provide good quality information for each province and each grade.  Provincial and western Canadian averages were calculated from results for each crop district, weighted by a combination of production by crop district using the averages of the 2010 and 2011 total production (Statistics Canada production estimate) combined with and an estimate of grade distribution per crop ditrict using data. 
All oil and protein content values discussed below are presented using the CGC’s historical 8.5% moisture basis in order to permit annual and regional comparisons. 

Exports of commercially cleaned canola contained up to 2.5% dockage, which will affect quality factors such as oil content, chlorophyll and FFA.  Canola exports containing over 2.5% dockage are considered not commercially clean (NCC) and will have even greater reductions in measured quality components.
