In an effort to provide alternatives to trans and saturated fats, scientists have been busy modifying the physical properties of oils to resemble those of fats. In this fashion, many food products requiring a specific texture and rheology can be made with these novel oil-based materials without causing significant changes to final product quality. The major approach to form these materials is to incorporate specific molecules (polymers, amphiphiles, waxes) into the oil components that will alter the physical properties of the oil so that its fluidity will decrease and the rheological properties will be similar to those of fats. These new oilbased materials are referred to as oil gels, or "oleogels," and this emerging technology is the focus of many scientific investigations geared toward helping decrease the incidence of obesity and cardiovascular disease. Presents a novel strategy to eliminate trans fats from our diets and avoid excessive amounts of saturated fat by structuring oil to make it behave like crystalline fat Reviews recent advances in the structuring of edible oils to form new mesoscale and nanoscale structures, including nanofibers, mesophases, and functionalized crystals and crystalline particles Identifies evidence on how to develop trans fat free, low saturate functional shortenings for the food industry that could make a major impact on the health characteristics of the foods we consume

Structure-Function Analysis of Edible Fats, Second Edition summarizes the latest approaches in the quantification of the physical structure of fats and its relationship to macroscopic functionality. The book takes a proven, general approach, presenting principles and techniques in a way that can be applied to any lipidic material. As the maturity of the field has increased since the first edition, there is an increased need for more sophisticated quantitative approaches to common problems encountered by industry. This book outlines modern methods used for this purpose by some of the leading authorities in the field today.

Edited by expert Alejandro Marangoni, and with contributions from leaders in field, the book features the latest developments, including chapters on Phase Behavior of Fat Mixtures and the Rheology and Mechanical Properties of Fats Methods Used in the Study of the Physical Properties of Fats (including a new section on microscopy).

Edible Oleogels, Structure and Health Implications, Second Edition presents a novel strategy on how to eliminate trans fats from our diets. Topics covered include how to avoid excessive amounts of saturated fat by structuring oil to make it behave like crystalline fat and how to develop trans fat free, low saturate, functional shortenings for the food industry. The major approach to form these materials is covered, helping manufacturers incorporate specific molecules (polymers, amphiphiles, waxes) into oil components. As such, this an ideal resource for those in product development and anyone interested in understanding the role of trans and saturated fats in health and nutrition.

Lipid science and technology has grown exponentially since the turn of the millennium. The replacement of unhealthy fats in the foods we eat, and of petroleum-based ingredients in the cosmetics we use, is a top priority for consumers, government, and industry alike. Particularly for the food industry, removing trans fats and reducing saturated fat in foods has produced a major challenge: How do we create structure with a minimum amount of structuring material? A comprehensive omnibus, Structure and Properties of Fat Crystal Networks, Second Edition clarifies the complex relationship between triglyceride composition of vegetable oils and fats, the physicochemical properties of triglycerides in simple and complex model systems, their crystallization, and melting behavior. Furthermore, it dives into the implications of these materials on the functional properties in food systems. Replacing ingredients, optimizing functionality, and improving health necessitate the ability to relate the structural organization present in a material to macroscopic properties. Revisiting concepts and approaches used in the study of fat crystal networks, the second edition includes new developments, particularly intermolecular interactions, and thoroughly updated analytical methods. Succinct, clear, and complete, this book is designed to help students and early-career researchers make the study of fats a more focused, less frustrating, and less expensive endeavor.

Food Scientists have been teaching the subject in the same way for the past fifty years. This book therefore aims to modernise the coverage of the subject, bringing it in line with the recent and extensive developments in Materials Science; in particular, the field of supramolecular chemistry of food components has been generally overlooked in textbooks. Edible Nanostructures will summarise developments in the areas of protein aggregation and gelation, starch crystallography, emulsions, and fat crystal network nanostructure and microstructure, addressing their functionalities in food. Each chapter offers both the qualitative view and a basic quantitative treatment of the area, including basic models used to describe structure and its relationship to functionality, if they exist.This is the first book on nanostructures in foods, and is suitable as a textbook for undergraduate students in Chemistry, Physics and Food Science.

This text provides a comprehensive and thorough overview of kinetic modelling in food systems, which will allow researchers to further their knowledge on the chemistry and practical use of modelling techniques. The main emphasis is on performing kinetic analyses and creating models, employing a hands-on approach focused on putting the content discussed to direct use. The book lays out the requisite basic information and data surrounding kinetic modelling, presents examples of applications to different problems and provides exercises that can be solved utilizing the data provided. Kinetic Analysis of Food Systems pursues a practical approach to kinetic analysis, providing helpful exercises involving chlorophyll degradation in processed vegetables, metabolic oscillations and sugar accumulation in cold-stored potatoes, transesterification of oils to manufacture biodiesel, aggregation of whey proteins to make protein gels and crystallization of fat stabilizers used in nut butters, among others. The book lays out the basics of kinetic modelling and develops several new models for the study of these complex systems. Taken together with the accompanying exercises, they offer a full portrait of kinetic analysis, from its basic scientific groundwork to its application.
