GE Canola That Produces DHA Passes Food and Feed Safety Study

October 6, 2021

Scientists from the United States and Australia recently published their work on the food and feed safety study of DHA canola, genetically engineered Brassica napus, which revealed its safety for use in human foods, nutraceuticals or animal feeds. This brings the DHA canola a step closer to being part of a solution to alleviate the high pressure in marine resources for the production of omega 3 fatty acids.

DHA canola is one of the first land-based production system for omega-3 long-chain polyunsaturated fatty acids that produce a high level of docosahexaenoic acid (DHA). The vector used to produce its desire oil profile contains the expression of cassettes of seven genes in the DHA biosynthesis pathway and was designed to convert oleic acid to DHA in its seed.

A full characterization of the DHA canola was done, which includes a detailed nutritional analysis of the seed, meal, and oil as part of the food and feed safety evaluation. The results showed that except for the fatty acid profile, none of the other compositional analytes showed differences when compared to their conventional counterpart. Fish feeding studies were also done to confirm the nutritional value and safety of the DHA canola. The scientists concluded that products derived from DHA canola are safe to use for human foods, nutraceuticals, or animal feeds.
