A fundamental understanding of the physical properties of fats, oils, and emulsifiers is essential to help the food processing industry meet consumer needs for quality foods with improved nutritional properties at a minimal cost. Food scientists, product development technologists, and food processors will be interested in this overview of both the fundamentals of fat crystallization and the application of those fundamental principles of food systems. This book was developed from papers that were presented at the conference on "The Physical Properties of Fats, Oils, and Emulsifiers with Application to Foods".

This book will review old and new methods to study emulsion stability and structure. Examples of emulsion-based foods include ice cream, yoghurt, and mayonnaise. The physicochemical properties of emulsions play an important role in food systems, as they directly contribute to the texture, sensory and nutritional properties of foods. One of the main properties is stability, which refers to the ability of an emulsion to resist physical changes over time. The development of an effective strategy to prevent undesirable changes in the properties of a particular food emulsion depends on the dominant physicochemical mechanism(s) responsible for the changes. In practice, two or more of these mechanisms may operate in concert. It is therefore important for food scientists to identify the relative importance of each mechanism, the relationship between them, and the factors that influence them, so that effective means of controlling the stability and physicochemical properties of emulsions can be established. Several techniques are used to study the physical behavior and structure of emulsions. Each technique has its advantages and disadvantages and provides different insights into the destabilization mechanisms. Among the oldest methods used to study emulsion stability is visual observation and small deformation rheometry. More recently, other techniques, such as ultrasound profiling, microscopy, droplet size distribution, and measurement of surface concentration to characterize adsorbed protein at the interface, have also been employed. Some of these techniques, such as droplet size distribution, involve some form of dilution. However, dilution disrupts some structures that play an important role in stability. The ability to study the stability of food emulsions in their undiluted form may reveal subtle nuances about their stability. Diffusing wave spectroscopy (DWS), laser scanning confocal microscopy (LSCM), nuclear magnetic resonance (NMR), and Turbiscan are among the more powerful, non-perturbing techniques used to characterized emulsions.

In Lipids: Structure, Physical Properties and Functionality, Professor Kire Larsson, Peter Quinn, Kiyotaka Sato and Fredrik Tiberg have provided an up-to-date description of the diversity of lipid molecular arrangements in different physical states as a basis for the understanding of lipid functionality in biological and technical systems. Lipids are components of many complex systems, some of which are natural in origin, such as the cell membranes of living organisms, and others created by human intervention, such as food emulsions. Scientists and technologists working on complex systems containing lipids need to relate composition and structure to behaviour, whether this is in the formulation of food products, development of drugs and drug delivery systems, study of living cells, or creation of new cosmetics, to name a few examples. This book was originally planned as a new edition to Kire Larsson's popular book Lipids: Molecular Organization, Physical Functions and Technical Applications published by the Oily Press in 1994. However, the subject area had to be expanded to such an extent that the one author could no longer cover it. Instead of resorting to the usual edited book with each chapter written by a different author, the three well-known scientists named above were invited to act as co-authors with Kire Larsson. As a result Lipids: Structure, physical properties and functionality is not a second edition, but a new book with a new ISBN number.

Since we produced Fats and Oils: Chemistry and Technology in 1980, the trend we anticipated to up-date the classical texts of oils and fats has manifested itself. Bailey's famous textbook has been completely revised and a second edition of Bernardini's work has been produced. The present text is an attempt to provide some insight into the current state of the art. Chapter 1 discusses the physical properties of oils and fats with special reference to those properties which can be monitored to give an in dication of the suitability of fats for chocolate production. The physical properties of the fats are often determined by the order in which the fatty acids are attached to the glyceride molecule. Ram Bhati, in the last article he wrote before his death, showed how mass spectrometry and chemical methods could be used to determine the sequence of fatty acids. Ram's essentially practical approach to the problem is exemplified by the section dealing with the experimental details of the techniques. Chapter 3 outlines some of the problems which can arise in industry when the lipid part of a foodstuff undergoes oxidation, whilst in Chapter 4 Patterson describes the major technique, hydrogenation, which is used to circumvent the problems caused by oxidation of the unsaturated fatty acids. In Chapter 4 the essentials of the theory are given to enable the reader to appreciate the design features of the apparatus. Chapter 5 deals with the analysis, mainly chromatographic, of lipids.

Abstract: An advanced college text for graduate and postdoctural students in health sciences covers most aspects of lipids, ranging from their physical and chemical properties, through their biochemical and metabolic pathways, to their role in nutrition. The 19 text chapters cover: the definition and solubility of lipids; fatty acid characteristics and properties (structures, crystals, films, and soaps; peroxidation, catabolism, and biosynthesis; and essential, unsaturated fatty acids); prostaglandins, thromboxanes, and prostacyclin; eicosanoids; the in vivo digestion, absorption, transport, and metabolism of lipids; triacylglycerol metabolism and adipose tissue metabolism; the biosynthesis of cholesterol and related lipids; the structure and properties of amphiphilic lipids; phosphoglyceride and sphingolipid metabolism; and the nutritional value of lipids. References are given at the end of each chapter, and numerous structures, reactions, and mechanisms are presented throughout the text.

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
