پردازش آلاینده‌ها در روغن‌های خوراکی: استرهای MCPD و گلیسیدیل

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 approaches for the removal of these contaminants after the completion of processing. Analytical strategies for accurate detection and quantitation of MCPD and glycidyl esters are covered, along with current information on their toxicological properties. This book serves as a single point of reference for the significant research related to these contaminants. Read more...

Alternative green food processing technologies have gained much technical and industrial attention in recent years as a potential means of reducing costs and promoting consumer awareness of corporate environmental responsibility. However, utilizing green principles is now becoming an effective business approach to enhance vegetable oil processing profitability. Two years have passed since the first edition of Green Vegetable Oil Processing was published. The Revised First Edition includes much of the content of the first edition, but incorporates updated data, details, images, figures, and captions. This book addresses alternative green technologies at various stages of oilseed and vegetable oil processing. This includes oil extraction technologies such as expeller, aqueous and supercritical methods, and green modifications of conventional unit operations such as degumming, refining, bleaching, hydrogenation, winterizing/dewaxing, fractionation, and deodorization. While most chapters describe soy oil processing, the techniques described equally applicable to oils and fats in general. Consumers worldwide are becoming more interested in what is in the foods they consume and how those foods are made. Edible oils, a leading source of dietary fats worldwide, are processed to improve consumer acceptance, by removing or modifying components that can negatively impact appearance, taste, and shelf stability. These processes can also produce variable levels of potentially harmful contaminants. Experts from around the globe in industrial processing, analytical chemistry, and toxicology have collaborated with AOCS to compile this text as a single point of reference for significant research related to monochloropropanediol (MCPD) and glycidyl esters in edible oils. Research addressing the mechanisms of formation of these contaminants, and the analytical techniques that have been used successfully to detect and mitigate their concentrations are discussed
