High levels of free fatty acids (FFA) were a serious problem in spring canola in 1988, 1991, 1995, 1999 and 2005. High FFA levels occur when oil molecules in the seed break apart. The acceptable upper limit is 1% FFA in the oil. All spring canola cultivars listed are resistant to the production of high FFA levels. Nevertheless, even these varieties can produce oil high in FFA if there is severe stress (heat and drought) during seed filling. Generally, high FFA levels occur in seed lots with a high brown (prematurely aborted) seed content at harvest. There appear to be consistent differences among varieties in FFA content and growing a recommended variety should minimize problems. The Canadian Grade Standard tolerance for 'Heat damaged' (brown seed) is 0.1% (Grade 1) and 0.5% (Grade 2). Heated seed has a distinct heated odour and when crushed, seed is dark chocolate brown-black in colour.
