is the result of collaborative work by top experts in the field of oleogel and related areas, who have brought together the knowledge gained in two decades of work on the design, development, understanding, and application of oleogels and oleogel-based systems in a comprehensive and easy-to-read book. This book covers a wide spectrum of topics, ranging from the basic understanding of these lipid-based materials to their practical application in real food products, highlighting the latest breakthroughs in the field. It comprises in-depth descriptions of both canonical and most advanced and recent techniques for the physical, chemical, digestive and physiological characterization of oleogels, as well as some regulatory and industrial considerations relevant to their production. This multifaceted approach brings new tools, standpoints, and perspectives for understanding and applying oleogels, empowering current and new generations of scientists, students, and professionals who are approaching this topic for the first time, or who already have some experience, to become experts in this field.
