Quality of western Canadian canola 2010



Fatty acid composition

The average level of erucic acid in the 2010 crop was 0.01% identical to last year average (0.01%), similar to the five-year average (0.04%) and well below the ten-year average (0.08%). This is also a direct result of the breeding efforts of the Canadian canola industry.

For Canola, No. 1 Canada samples the mean a-linolenic acid (C18:3) was 10.0% equal the mean observed in 2009 (10.0%) and for the five‑year mean. The α-linolenic acid mean in Alberta (10.5%) was  slightly higher than in Saskatchewan (10.0%) and Manitoba (9.4%).

For Canola, No. 1 Canada samples the mean oleic acid (C18:1) content of the 2010 crop was 62.2%, identical to the average observed in 2009 (62.2%). In average, oleic acid content was much higher in Manitoba than in Saskatchewan and Alberta.

In 2010, there was also a similar average for linoleic acid (C18:2) when compare to 2009 (18.9 versus 18.8%). These similar averages results for oleic aicd, linoleic acid and α-linolenic acid resulted in a similar iodine value when compare to 2009.

The mean level of saturated fatty acids was 6.85% in 2010, similar to the 2009 value of 6.8%. The mean saturated fatty acid levels were slightly different of the three provinces in 2010 (7.0, 6.9 and 6.7% for Manitoba, Saskatchewan and Alberta, respectively). Usually, samples from the southern prairies have significantly higher saturated fatty acids than samples from the northern regions.

For Canola, No. 1 Canada samples, the mean iodine value of the oil was 113.8 units similar to last year results  (113.7 units).

The October 2010 data showed that the α-linolenic acid mean for Canola No. 1 Canada exports was 10.1 %, slightly higher than the 2009-2010 export mean (9.8%). At 114.3 units, the iodine value for December  2010 canola exports increased by 1 units from the 2009-10 levels. The level of saturated fatty acids in the December 2010 canola exports remained very similar to the 2009-2010 means (6.6% versus 6.8%). It is expected that the levels of erucic acid will remain constant during the 2009-2010 shipping season, between 0.03% and 0.05%, well below 0.1%. It is likely that there will be no significant change in average for export canola shipments regarding iodine value, erucic acid, oleic acid and a-linolenic acid contents for the 2010-2011 shipping season.
