Summary
This review synthesises current knowledge on extraction technologies for omega-3 fatty acids from fish processing by-products, addressing both environmental sustainability and nutritional value recovery. The authors examine innovative extraction approaches and evaluate the potential for these omega-3-enriched extracts to be incorporated into food and animal feed systems. The work positions fish by-product valorisation as a strategy to improve resource efficiency within aquaculture and fisheries supply chains whilst potentially enhancing the nutritional profile of food and feed products.
Regional applicability
The findings are relevant to UK and European aquaculture and seafood processing industries seeking to improve resource efficiency and comply with circular economy objectives. The extraction methods and feed applications discussed may inform UK livestock and aquaculture nutrition strategies, particularly in light of growing interest in sustainable omega-3 sources for farmed fish and livestock feed.
Key measures
Extraction methods and efficiency; omega-3 fatty acid composition (EPA and DHA); applications in food and feed; potential nutritional and sustainability benefits
Outcomes reported
The study examined innovative extraction methods for omega-3 fatty acids from fish by-products and their potential applications in food and feed formulations. It likely assessed extraction efficiency, omega-3 yield, and feasibility of incorporating these extracts into food and animal feed products.
