Valorizing fish canning industry by-products to produce ω-3 compounds and biodiesel

- An inexpensive strategy was used to valorize fish canning industry by products.
- Urea complexation was more efficient than winterization.
- The solid fraction contained 79.94% (w∕w) of saturated and monounsaturated FAME.
- The liquid fraction was further analysed by preparative HPLC analysis.
- After HPLC analysis, an oil fraction containing 89.25% EPA (w∕w) was obtained.
