Special Issue Information

Dear Colleagues,

Marine lipids, and especially long chain polyunsaturated omega-3 fatty acids, play important roles in human nutrition and health. Despite their well-documented health effects, the global population do not eat enough seafood and generally do not meet the recommended levels of these omega-3 fatty acids through their diet. Marine lipids may be used as ingredient in food products, and an increased understanding of their physio-chemical and nutritional properties, as well as their stability in a food matrix, could help in improving their potential use.

The ocean comprises many species that, today, are not utilised as food. These can be species at lower tropic levels than those caught for commercial fisheries and may become future food ingredients. Additionally, seafood resources that are lost through value chains may be upcycled as marine lipids sources for human consumption.

This Special Issue invites original research and review papers with new knowledge in order to increase the future consumption of marine lipids. This could include new and current marine lipid resources and their properties in food, composition and stability, logistics and value chains, extraction and refinement, technologies, and consumer insight regarding marine lipids in food. Papers focusing on physio-chemical properties and nutrition of marine lipids are particularly welcome.

This study investigates the use of untapped mesopelagic species as a source of long-chain polyunsaturated omega-3 fatty acids (LC n-3 PUFAs) to meet the growing demand. The challenges faced by commercial fishing vessels, such as varying catch rates and species distribution affecting lipid levels, are addressed. Marine oils were produced post-catch using thermal separation and enzymatic hydrolysis during four commercial cruises, screening approximately 20,000 kg of mixed mesopelagic species. Maurolicus muelleri and Benthosema glaciale were the dominant species in the catch, while krill was the primary bycatch. The lipid composition varied, with B. glaciale having a higher prevalence of wax esters, while triacylglycerols and phospholipids were more predominant in the other species. LC n-3 PUFAs ranged from 19% to 44% of lipids, with an average EPA + DHA content of 202 mg/g of oil. Both processing methods achieved oil recoveries of over 90%. Estimates indicate that the mesopelagic biomass in the Northeast Atlantic could supply annual recommended levels of EPA + DHA to 1.5 million people, promoting healthy heart and brain functions. These findings offer valuable insights for considering mesopelagic species as a potential source of dietary marine lipids, laying the groundwork for further research and innovation in processing and obtaining valuable compounds from such species.
