Omega-3 Delivery Systems: Production, Physical Characterization and Oxidative Stability offers the most recent updates for developing, characterizing, and stabilizing both traditional and novel omega-3 delivery systems, including their final incorporation into food matrices and physicochemical changes during digestion. The book brings chapters on novel omega-3 delivery systems (e.g., high-fat emulsions, Pickering emulsions, electrosprayed capsules, and solid lipid nanoparticles), the application of advanced techniques to evaluate physical and oxidative stabilities (e.g., SAXS, SANS, ESR, and super-resolution fluorescence microscopy), and new developments of food enrichment and physicochemical changes during digestion. The book provides a unique multidisciplinary and multisectoral approach, i.e., featuring authors from industry and academy.
Long chain omega-3 polyunsaturated fatty acids (PUFA) present numerous health benefits; however, the consumption of natural products rich in omega-3 PUFA (e.g., fish, krill, and algae) is not enough to reach the daily-recommended values. Therefore, the food industry is highly interested in producing omega-3 fortified foods.

Bet�l Yesiltas National Food Institute, Technical University of Denmark. Bet�l Yesiltas, PhD, is a Researcher on tenure track working as part of the Bioactives group at the National Food Institute, in the Technical University of Denmark. Since completing her PhD on the physical and oxidative stability of highfat omega-3 delivery oil-in-water emulsions in 2019. She has mainly been working in the area of food structure and lipid oxidation. She is expanding her knowledge on the use of small-angle X-ray and neutron scattering techniques in complex food emulsions, which has high potential to elucidate oil-water interfacial structure. Before her academic career started, she had worked in Research & Development departments of some of the world's leading companies such as Danone and Unilever. Bet�l's research interests include, but are not limited to, antioxidants, emulsifiers, oil-water interfacial structure, physical and oxidative stability of fish oil-in-water emulsions, lipid oxidation infoods or model food systems, and bioavailability of bioactive compounds.
