Quality of Canadian Soybean, oilseed-type 2019
6. Free fatty acid content
Grade composites of Soybean, No. 1 Canada and Soybean, No. 2 Canada showed free fatty acid levels averaging 0.18% in 2019 (Table 1 and 3). This is slightly higher than last year’s results (0.15%).
High free fatty acid values are mainly due to seed damage which results from increased exposure to moisture and oxygen from wet harvesting conditions and improper storage. Free fatty acid levels could increase during storage due to storage and environmental conditions.
