About this ebook

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. - Brings a holistic approach of omega-3 delivery systems, bringing scientific understanding on production, physical characterization, and oxidative stability - Covers key aspects to develop, characterize, and use omega-3 delivery systems for food enrichment, considering physicochemical changes occurring during digestion - Serves as an interface between lipid oxidation and colloids chemistry, encapsulation techniques, soft matter physics, food development, and nutrients bioavailability

About the author

Dr. Pedro J. García-Moreno is an associate professor at the Department of Chemical Engineering at the University of Granada (Spain). His research focuses on the up-grading of food by-products by the obtaining of ingredients with bioactive and/or functional properties. This includes the development of novel strategies to extract, stabilize and deliver bioactive ingredients such as omega-3 fatty acids and protein hydrolysates/peptides. He has received several awards by EuroFedLipid, AOCS and ANQUE. He serves as associate editor in the Journal of American Oil Chemists’ Society (JAOCS) and the Journal of the Science of Food and Agriculture (JSFA). He has published 95 scientific publications including peer-reviewed scientific articles and book chapters.

Dr. Charlotte Jacobsen is professor in Bioactives – Analysis and Application at the National Food Institute, Technical University of Denmark (DTU), where she leads the Bioactives - Analysis and Application Research Group. She is internationally renowned for her research in omega-3 rich foods and the use of underutilized aquatic biomasses for food and feed purposes. She has received several awards for her work. Her publication list includes more than 300 peer-reviewed manuscripts and book chapters.

Ann-Dorit Moltke Sørensen, PhD, is a Senior Researcher in the Research group for Bioactives-Analysis and Application at the National Food Institute, Technical University of Denmark. She obtained her PhD in 2010 from the Technical University of Denmark. Her research focuses on the area of lipid oxidation in foods, antioxidants, and their efficacy in emulsified systems. She has received a Young Scientist award by the Nordic Lipid Forum and a European Student Travel award by the EAOCS board. Moreover, she received the Edwin Frankel Best Paper award in 2012 in lipid oxidation and quality. Her publication list includes 40 peer-reviewed manuscripts and book chapters.

Betül 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. Betül'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.
