Book Description
This Springer Brief gives an overview of recent research conducted in the area of oil structuring starting with a detailed introduction on oleogelation and properties of food-approved building blocks followed by the discussion of some illustrative examples to explain the processing steps required for creating oleogels, advanced characterization (rheological, thermal and microstructural) and some potential edible applications of oleogels. The book w concludes with a section summarizing the general guidelines on the properties of oleogels and practically of approach with regards to the specific category of building blocks used for structuring. The text also lists some unresolved challenges that need to be addressed in order to fully exploit oleogelation for future food product development. The functional application of liquid oils in food product development is mostly accomplished by structuring them into soft, plastic-like materials. This structuring of oil is traditionally based on the fat crystal network formed by high melting triacylglycerol (TAG) molecules that are rich in trans and/or saturated fatty acids. Currently, due to the factors such as the requirement for trans- and saturated fat-free food products, sustainable manufacturing and ethical trade practices, the research in the area of identifying alternative routes to oil structuring (in the absence of trans and saturated fats) has been regarded as a ‘hot topic’ in the bio-scientific community. Oleogelation (gelling of liquid oil in absence of crystallizable TAGs) is one such alternative, which has recently attracted tremendous attention from researchers and industrial scientists working in the domain of food product development. The possibility of creating structured gels that contain a large amount of liquid oil (usually above 90 wt%) opens up many possibilities to develop food products with better nutritional profiles.

Book Description
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

Book Description
The most useful properties of food, i.e. the ones that are detected through look, touch and taste, are a manifestation of the food’s structure. Studies about how this structure develops or can be manipulated during food production and processing are a vital part of research in food science. This book provides the status of research on food structure and how it develops through the interplay between processing routes and formulation elements. It covers food structure development across a range of food settings and consider how this alters in order to design food with specific functionalities and performance. Food structure has to be considered across a range of length scales and the book includes a section focusing on analytical and theoretical approaches that can be taken to analyse/characterise food structure from the nano- to the macro-scale. The book concludes by outlining the main challenges arising within the field and the opportunities that these create in terms of establishing or growing future research activities. Edited and written by world class contributors, this book brings the literature up-to-date by detailing how the technology and applications have moved on over the past 10 years. It serves as a reference for researchers in food science and chemistry, food processing and food texture and structure.

Book Description
The physical properties associated with the saturated and trans fats obtained through partial hydrogenation of vegetable oils (PHVOs) provide the solid fat content, melting and textural properties that consumers require in food products like butter, margarines, vegetable creams, spreads, and confectionary fats. However, saturated and trans fats increase low density lipoprotein, while trans fats also lower high-density lipoprotein serum levels. These indicators increase the risk of developing cardiovascular disease, type II diabetes, stroke, and have recently been associated with metabolic syndrome. Consequently, regulatory agencies worldwide have passed legislation restricting the addition of PHVOs and their derivatives (i.e., shortenings) to food products. This has lead research groups worldwide to investigate different mechanisms to provide structural and physical properties to edible, healthy unsaturated oils. The overall objective is to achieve similar functional properties to those provided by PHVOs and shortenings to food products. This book encompasses the work of leading researchers discussing, from a scientific and technological perspective, the latest and most innovative approaches to structure edible oils without the use of trans fats. Additionally, the authors discuss practical uses and technical limitations associated with the use of "structured edible oils" in different food systems. Appealing to researchers and professionals working in lipid science, food chemistry and fat metabolism, it fills the gap in the literature for a book in this fast-changing field.

Book Description
Structure plays an important role in heterogeneous catalysis. It provides a framework for the arrangement and stragetic placement of key catalytic elements, hosting them in a prescribed manner so that their respective electronic properties can exhibit their desired catalytic functions and mutual interactions. Under reaction conditions these framework structures and their catalytic guests undergo dynamic processes becoming active participants of the overall catalytic process. They are not mere static geometric forms. The dynamics of catalytic structures are particularly vivid in selective oxidation catalysis where the lattice of a given catalytic solid partakes as a whole, not only its surface, in the redox processes of the reaction. The catalyst becomes actually a participating reagent. By proper choice of key catalytic elements and their host structures, preferred catalytic pathways can be selected over less desired ones. However, not only in selective redox catalysis does structure play an important role, its importance is also well documented, among others, in shape selective zeolite catalysis, enantioselective hydrogenation and hydrodesulfurization. The contributions presented in this book address the dynamic character of the solid state under catalytic reaction conditions. By relating structure to activity and selectivity in heterogeneous catalysis our understanding of such correlations has been significantly enhanced through the use of sophisticated spectroscopic means, surface science and modeling.
