This book discusses 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. The mechanisms of formation for these contaminants, as well as research identifying possible precursor molecules are reviewed. Strategies which have been used successfully to decrease the concentrations of these contaminants in edible oils are discussed, including the removal of precursor molecules before processing, modifications of deodorization protocol, and approache

Fully revised and updated, Processing Contaminants in Edible Oils, 2nd edition, presents the latest 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. A number of advancements in understanding these have been made since the publication of the first edition. These important changes, which impact industrial mitigation, analytical methods, toxicology and regulation, are highlighted for up-to-date reference. The mechanisms of formation for MCPD and glycidyl 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 contaminants are presented.

Lipid oxidation in food systems is one of the most important factors which affect food quality, nutrition, safety, color and consumers' acceptance. The control of lipid oxidation remains an ongoing challenge as most foods constitute very complex matrices. Lipids are mostly incorporated as emulsions, and chemical reactions occur at various interfaces throughout the food matrix. Recently, incorporation of healthy lipids into food systems to deliver the desired nutrients is becoming more popular in the food industry. Many food ingredients contain a vast array of components, many of them unknown o

Patent literature has always been a mine of information, but until recently, it was difficult to access. Now, with the Internet, access to all patent documents is almost instantaneous and free. However, interpreting the technical information provided by patent literature requires a certain skill. This monograph aims to provide that skill by explaining patent jargon and providing background information on patenting. Patents dealing with edible oil processing are used to explain various aspects of patenting. To make the explanations less impersonal, some have been larded with personal remarks and experiences. Accordingly, this monograph is intended for scientists and engineers dealing with edible oils and fats who want to extend their sources of technical information. Hopefully, it will inspire them to innovate, help them to avoid duplication, and provide them with some amusement. About the Author Albert Dijkstra studied chemistry at Leiden University, specializing in gas kinetics. He never received any specific training in the three subjects treated in this monograph: lipid chemistry, chemical technology, and patents. That may be the reason why he continues to query what he does not understand in these subjects, question established truths, and expose myths. As a result, he has developed several novel processes in the field of directed interesterification, degumming, dry fractionation, and the regeneration of spent bleaching earth. He has also derived an equation for the stripping medium usage in continuous counter-current vacuum stripping, suggested an improved mechanism for the chemical interesterification reaction, contributed to the understanding of the hydrogenation process by highlighting the role of the hydrogen concentration, and introduced the determination of trace metals by ICP in the field of edible oil analysis. This has led to wide recognition: AOCS Chang Award (1997), EuroFedLipid Technology Award (2002), AOCS Bailey Award (2009), AFECG Chevreul Medal (2009), AOCS Mounts Award (2010). He is also a Fellow of the AOCS and Associate Editor of its journal and its Lipid Library website. Although retired, he is active as a scientific consultant, author, editor, inventor, and lecturer.
