Quality of Canadian Soybean, oilseed-type 2017
6. Chlorophyll and Free fatty acid content
Grade composites of Soybean, No. 1 Canada and Soybean, No. 2 Canada showed free fatty acid levels averaging 0.13% in 2017 (Table 1 and 3). This is similar to last year’s results (0.12%).
High free fatty acid values are mainly due to seed damage which results from exposure to moisture and oxygen, wet harvesting conditions and improper storage. Free fatty acid levels could increase during storage due to storage and environmental conditions.
