Salmon Processing Waste: A Prospective Source for Nutraceuticals

This report summarizes a series of small studies on the production of omega-3 concentrates from salmon by-products. Because raw material must be of highest quality for the production of nutraceuticals (i.e. omega-3 capsules), spoilage rates and fatty acid composition changes were examined by applying different handling and pretreatment procedures. Further, different enzymatic methods for concentrating omega-3 fatty acids from oil were compared. The results provided important insight and will be used as part of larger initiatives on the creation of a Biorefinery strategy for the province’s aquaculture waste. The knowledge and experience gained by the Bioprocessing team and the fine-tuned analytical methods, especially GC (Gas Chromatography) will be highly valuable for academic and industry use in future projects
