Quality of western Canadian flaxseed 2011
Free fatty acids content
The average free fatty acids (FFA) content of 0.20% in top grade 2011 survey samples is similar to the 2009 average and below the 10-year mean of 0.24% (Figure 4). The average FFA content of Manitoba samples, 0.26% is higher than Saskatchewan's and Alberta's FFA value of 0.16% and 0.17%, respectively. Higher FFA values are mainly due to seed damage resulting from exposure to moisture and oxygen, for example during wet harvesting conditions or improper storage.
The lower grade samples (No. 2 CW to Canada Sample Grade) had a mean FFA content of 1.00%.
The FFA content of Flaxseed, No. 1 CW exports for 2010-2011 exports was 0.50%.
