DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKThe second edition of this book on lipids, lipoprotein and membrane biochemistry has two major objectives - to provide anadvanced textbook for students in these areas of biochemistry,and to summarise the field for scientists pursuing research inthese and related fields. Since the first edition of this book was published in 1985 theemphasis on research in the area of lipid and membrane biochemistry has evolved in new directions. Consequently, thesecond edition has been modified to include four chapters on lipoproteins. Moreover, the other chapters have been extensivelyupdated and revised so that additional material covering the areas of cell signalling by lipids, the assembly of lipids andproteins into membranes, and the increasing use of molecular biological techniques for research in the areas of lipid, lipoprotein and membrane biochemistry have been included. Each chapter of the textbook is written by an expert in the field, but the chapters are not simply reviews of current literature. Rather, they are written as current, readable summaries of these areas of research which should be readily understandable to students and researchers who have a basic knowledge of general biochemistry. The authors were selected fortheir abilities both as researchers and as communicators. In addition, the editors have carefully coordinated the chapters sothat there is little overlap, yet extensive cross-referencing among chapters.

DOWNLOAD EBOOKChemical and Functional Properties of Food Lipids provides a concise, straightforward treatment of the present state of knowledge of the nomenclature, content, composition, occurrence, distribution, chemical and biological reactivity, functional properties, and biological role of lipids in food systems. Written by a team of international researchers and based on the available world literature, this book examines the nature, technological properties, reactivity, and health-related concerns and benefits of food lipids. It covers the effects of storage and processing conditions on all aspects of quality of lipid-containing foods and reviews the current state of techniques for lipid analysis. The volume also discusses the importance of lipids in the human diet and includes a comparison of dietary recommendations for lipid intake. This is a valuable reference for researchers and graduate students in food chemistry and nutrition.

DOWNLOAD EBOOKLipids in Foods: Chemistry, Biochemistry and Technology provides basic information on the biochemistry and technology of the fatty acids or lipids. This book notes that natural and processed fats and oils, whether of animal or vegetable origin, play a significant role in the economy of several countries including both oil-producers and oil-users. These materials are used extensively, but not exclusively, in the food industry. The first 10 chapters cover the basic chemistry and biochemistry of the fatty acids and their natural derivatives. These topics include an account of the chemical structure, separation, analysis, biochemistry, physical properties, chemical properties, and synthesis of these compounds. The remaining chapters include the recovery of fats and oils from their sources and the processes of refining, bleaching, hydrogenation, deodorization, fractionating, and interesterification. A segment is devoted to margarines and shortenings and to the problems of flavor stability and antioxidants. This text will be valuable to students wishing to know more about lipids and to those involved in this field of study.

DOWNLOAD EBOOKSince 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.
