Process for obtaining a polyunsaturated fatty acid having at least 20 carbon atoms (LC-PUFA) or an oil comprising a LC-PUFA from seeds, said process comprising
- (A) one or more or all of (i) to (vi):
- providing seeds comprising a LC-PUFA and/or an oil comprising a LC-PU FA,
- (ii) drying the seeds
- (iii) storing the seeds
- (iv) grinding and/or flaking the seeds
- (v) heating the seeds
- (vi) pressing the seeds such as to expell a fraction of oil
- And,
- (B) obtaining the LC-PUFA or oil comprising the LC-PUFA from the seeds,
- optionally by extraction with a solvent.
Process according to any preceding claim, wherein, e.g. in one or more of (i) to (vi)
- less than 5% of the seeds are total damaged seeds;
- less than 2% of the seeds are distinctly green seeds;
- and/or
- less than 0.1% of the seeds are heated seeds,
- as determined in accordance with the Official Grain Grading Guide. 2001 of the Canadian Grain Commission
