Book Synopsis Chemistry of Maillard Reactions in Processed Foods by : Salvatore Parisi
Download or read book Chemistry of Maillard Reactions in Processed Foods written by Salvatore Parisi and published by Springer. This book was released on 2018-06-29 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief explains the importance of Maillard reactions in food processing. It underlines that the term “Maillard reaction” actually does not describe one single chemical reaction, but an entire class of chemical reactions, which lead to browning, with a strong impact on visual appearance, odor, and flavor. It emphasizes that the Maillard reactions are still not fully characterized, despite extensive historical studies. While under the right conditions Maillard reactions have many favorable effects (e.g. formation of antioxidants), the Brief discusses that there are also conditions where Maillard reactions can result in toxic or mutagenic reactions. Hence, it emphasizes that the reaction should be viewed as a complex network of various sub-reactions, with a plethora of concomitant reaction mechanisms and kinetics. This Brief thus makes a step toward a holistic evaluation of the complexity of the Maillard reaction scheme, with the aim of making better and more targeted use in food processing.

Book Synopsis Process-Induced Chemical Changes in Food by : Fereidoon Shahidi
Download or read book Process-Induced Chemical Changes in Food written by Fereidoon Shahidi and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical changes that occur in foods during processing and storage are manifold and might be both desirable and undesirable in nature. While many of the processes are carried out intentionally, there are also certain unwanted changes that naturally occur in food and might have to be controlled. Therefore, efforts are made to devise processing technologies in which desirable attributes of foods are retained and their deleterious ef fects are minimized. While proteins, lipids and carbohydrates are the main nutrients of food that are affected by processing, it is their interaction with one another, as well as in volvement oflow-molecular-weight constituents that affects their flavor, color and overall acceptability. Thus, generation of aroma via thermal processing and bioconversion is of utmost importance in food preparation. Furthermore, processing operations must be opti mized in order to eliminate or reduce the content of antinutrients that are present in foods and retain their bioactive components. Therefore, while novel processing technologies such as freezing, irradiation, microwaving, high pressure treatment and fermentation might be employed, control process conditions in a manner that both the desirable sensory attributes and wholesomeness of foods are safeguarded is essential. Obviously, method ologies should also be established to quantitate the changes that occur in foods as a result of processing. This volume was developed from contributions provided by a group of internation ally-recognized lead scientists.
Book Synopsis Chemical Changes in Food During Processing by : Richardson
Download or read book Chemical Changes in Food During Processing written by Richardson and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume results from the Eighth Basic Symposium held by the Institute of Food Technologists in Anaheim, California on June 8-9, 1984. The theme of the symposium was "Chemical Changes in Food during Processing." The speakers included a mix of individuals from academic institu tions, governmental agencies, and the food industry. Twenty speakers discussed topics ranging from the basic chemistry relating to food constituents to the more applied aspects of chemical changes in food components during food processing. It was the intent of the organizers to bring together a group of speakers who could address the chemistry of changes in food compo nents during processing from a mechanistic point of view. As a con sequence, the proceedings of this symposium emphasize the basic chemistry of changes in food constituents from a generic perspective which is intended to provide the reader with a background to address more specific problems that may arise.
Book Synopsis Fundamentals of Food Chemistry by : Werner Heimann

Available in PDF, EPUB and Kindle. Book excerpt: Distributed in Hungary, Albania, Bulgaria, China, Cuba, Czechoslovakia, GDR, Dem People's Rep of Korea, Mongolia, Poland, Roumania, Soviet Union, Dem Rep of Vietnam and Yugoslavia by Avicenum, Czechoslovak Medical Press, Praha The book deals with the chemical reactions taking place in food during industrial processing and storage, and shows how various food components react according to their chemical composition and the influence of other components or processing conditions. The work describes in detail the changes of the main food components (proteins, saccharides, lipids) and of other components important from the standpoint of the nutritional, sensory and hygienic properties of food materials. Important changes of physical properties (which may affect the chemical reactivity) are given as well. The most important reactions are elucidated on examples from technological processes which also show the effect of these chemical reactions on the most important properties of food products.
