Processing Contaminants in Edible Oils: MCPD and Glycidyl Esters, Second Edition, is the fully revised and updated discussion of the current research on monochloropropanediol (MCPD) and glycidyl esters in edible oils. These potentially harmful contaminants are formed during the industrial processing of food oils during deodorization. There have been a number of changes in the area of MCPD and Glycidyl Esters research since the first edition was written, impacting industrial mitigation, analytical methods, toxicology, and regulation and these are now integrated into this valuable single-source volume. The mechanisms of formation for MCPD and glvcidyl ester contaminants, as well as research identifying possible precursor molecules are reviewed, as are strategies which have been used successfully to decrease the concentrations of these contaminants. From the removal of precursor molecules before processing, modifications of deodorization protocol, to approaches for the removal of these contaminants after the completion of processing, methods of mitigating and eliminating are presented. Analytical strategies for accurate detection and quantitation of MCPD and glycidyl esters are covered, along with current information on their toxicological properties. These contaminants have recently been the subject of regulations worldwide in an attempt minimize their presence in foods, particularly infant formula. This book will review the methods used to detect them, it will describe approaches to minimize their formation during processing, as well as attempts to remove them from oils. Results of research into possible negative health effects are also included.

Oils and fats are almost ubiquitous in food processing, whether naturally occurring in foods or added as ingredients that bring functional benefits. Whilst levels of fat intake must be controlled in order to avoid obesity and other health problems, it remains the fact that fats (along with proteins and carbohydrates) are one of the three macronutrients and therefore an essential part of a healthy diet. The ability to process oils and fats to make them acceptable as part of our food supplies is a key component in our overall knowledge of them. Without this ability, the food that we consume would be totally different, and much of the flexibility available to us as a result of the application of processing techniques would be lost. Obviously we need to know how to process fatty oils, but we also need to know how best to use them once they have been processed. This second edition of Edible Oil Processing presents a valuable overview of the technology and applications behind the subject. It covers the latest technologies which address new environmental and nutritional requirements as well as the current state of world edible oil markets. This book is intended for food scientists and technologists who use oils and fats in food formulations, as well as chemists and technologists working in edible oils and fats processing.

Methods for identification and measurement of existing and newly discovered contaminants are required, especially those that are cheap, simple and rapid, so that testing may be more frequent within the food supply chain. This book examines the formation of toxic compounds during the processing of food and strategies to mitigate their creation. Modification of process conditions can reduce the health risks posed by these compounds to consumers. This new volume will update knowledge on current methods for mitigation of these process contaminants and is aimed at industrialists in food processing, academic researchers and graduate students studying food science and technology or food engineering.

Functional Dietary Lipids: Food Formulation, Consumer Issues and Innovation for Health discusses this important component of the human diet and the ways it plays an essential functional role in many foods. The book covers the functionality and nutritional benefits of dietary fat in food in terms of formulation, manufacturing, and innovation for health. After an introduction by the editor reviewing the role of fats in the human diet, the book discusses the chemistry of edible fats, manufacturing issues, including the replacement of trans-fatty acids in food, fat reformulation for calorie reduction, thermal stability of fats, and the flavor and functional texture and melting characteristics of fats in food. Subsequent chapters address the effect of dietary lipid intake on various health issues and the potential health benefits of bioactive compounds in dietary lipids, with final sections discussing issues that affect the consumer relationship with fat, such as regulation, marketing, and health claims. Comprehensively examines the functionality and nutritional benefits of dietary fat in food Discusses the chemistry of edible fats, manufacturing issues, including the replacement of trans fatty acids in food, fat reformulation for calorie reduction, thermal stability of fats, and more Considers manufacturing issues of dietary fat in foods Addresses issues affecting the consumer relationship with fat, such as regulation, marketing, and health claims

In 2010, esteemed researchers gathered at a workshop held at the Richardson Centre for Functional Foods and Nutraceuticals at the University of Manitoba in Winnipeg, Canada. Drawn from these proceedings, Canola and Rapeseed: Production, Processing, Food Quality, and Nutrition presents state-of-the-art information on the chemistry of the minor constituents of canola and rapeseed and their impact on human health. The book also identifies new areas of research and opportunities for the industrial application of functional foods and nutraceuticals from canola and rapeseed. Topics include: The historical development, properties, and performance of canola Characteristics and bioactives of sinapic acid derivatives and the decarboxylation pathways leading to their formation Canola protein processing High omega-9 canola oils and their future applications Modification of Brassica oilseeds Rapid analytical methods for measuring oil content The potential of ultrasound and supercritical fluid extraction for producing value-added by-products The processing of virgin rapeseed oils in Europe Extraction and application of canola protein The frying stability of high-oleic low-linolenic acid canola oils The potential of mustard oil for biodiesel The final chapters demonstrate the health benefits of canola, including antioxidant, antimutagenic, and anticancer properties. Authored by experienced researchers in the field, the book chapters have been expanded considerably to include a number of areas not contained in the original workshop, providing comprehensive coverage of the potential of this essential crop.

Driven both by real industrial needs and curiosity for fundamental research, edible oil structuring has emerged as a subject of growing interest with applications in real food systems. With contributions from leading research groups around the world, this book provides a comprehensive and concise overview of the field with special emphasis on the updates from the last 5 years. New insights into the mechanism of gelation in mono- and multicomponent gels are discussed for several categories of previously known structuring agents along with the potential food applications of some of these systems. In addition, use of alternative methods to explore structuring properties of hydrophilic biopolymers are presented with illustrative examples. Some new concepts such as bio-based synthesis of supergelators, foamed oleogels and use of innovative dispersion techniques give a broader picture of the current research in edible oil structuring. This book will be of interest to students, academics and scientists involved in the research of edible oil structuring. It will be an important reference as it provides current information on the state-of-the-art of the field.

Aflatoxins are a group of highly toxic and carcinogenic substances, which occur naturally, and can be found in food substances. Aflatoxins are secondary metabolites of certain strains of the fungi Aspergillus flavus and A. parasiticus and the less common A. nomius. Aflatoxins B1, B2, G1, and G2 are the most important members, which can be categorized into two groups according to the chemical structure. As a result of the adverse health effects of mycotoxins, their levels have been strictly regulated especially in food and feed samples. Therefore, their accurate identification and determination remain a Herculean task due to their presence in complex food matrices. The great public concern and the strict legislation incited the development of reliable, specific, selective, and sensitive analytical methods for pesticide monitoring that are discussed in this book.
