Numerous nutritional findings and extensive evidence on the health benefits of diet and exercise have emerged since the publication of the successful first edition. Recent concerns about trans isomers acting like saturated fatty acids have encouraged formulation changes that require fats and oils processors to revise their preparation techniques. U

For the first time in over twenty-five years, this unique and popular textbook on food chemistry mechanism and theory has received a full update. Emphasizing the underlying chemical reactions and interactions that occur in foods during processing and storage, this book unifies the themes of "what", "how" and "why" in the language of equations, reactions and mechanisms. This book is the only work which provides in-depth focus on aspects of reaction mechanisms and theories in the chemistry of food and food systems. With more than 500 chemical equations and figures, this book provides unusual clarity and relevance, and fills a significant gap in food chemistry literature. It is a definitive source to consult regarding the important mechanisms that make food components and reactions tick. Mechanism and Theory in Food Chemistry has been a popular resource for students and researchers alike since its publication in 1989. This important new edition contains updates on the original text encompassing a quarter century of advances in food chemistry. Many parts of the original chapters are revised to make for smoother navigation through the subjects, to better explain the underlying chemistry concepts and to fulfill the need of adding topics of emerging importance. New sections on fatty acids, lipid oxidation, meat, milk, soybean and wheat proteins, starch and many more have been incorporated throughout the revision. This updated edition provides an excellent source of all the important chemical mechanisms and theories involved with food science.

Food emulsions have existed since long before people began to process foods for distribution and consumption. Milk, for example, is a natural emulsion/colloid in which a nutritional fat is stabilized by a milk-fat-globule membrane. Early processed foods were developed when people began to explore the art of cuisine. Butter and gravies were early foods used to enhance flavors and aid in cooking. By contrast, food emulsifiers have only recently been recognized for their abil ity to stabilize foods during processing and distribution. As economies of scale emerged, pressures for higher quality and extension of shelf life prodded the de velopment of food emulsifiers and their adjunct technologies. Natural emulsifiers, such as egg and milk proteins and phospholipids, were the first to be generally utilized. Development of technologies for processing oils, such as refining, bleaching, and hydrogenation, led to the design of synthetic food emulsifiers. Formulation of food emulsions has, until recently, been practiced more as an art than a science. The complexity offood systems has been the barrier to funda mental understanding. Scientists have long studied emulsions using pure water, hydrocarbon, and surfactant, but food systems, by contrast, are typically a com plex mixture of carbohydrate, lipid, protein, salts, and acid. Other surface-active ingredients, such as proteins and phospholipids, can demonstrate either syner- XV xvi Preface gistic or deleterious functionality during processing or in the finished food.

Ever wondered why bread rises? Or why dough needs to rest? From cakes and biscuits to flat breads and standard loaves, the diversity of products is remarkable and the chemistry behind these processes is equally fascinating. The Science of Bakery Products explains the science behind bread making and other baked goods. It looks at the chemistry of the ingredients, flour treatments, flour testing and baking machinery. Individual chapters focus on the science of breads, pastry, biscuits, wafers and cakes. The book concludes with a look at some experiments and methods and goes on to discuss some ideas for the future. The Science of Bakery Products is an interesting and easy to read book, aimed at anyone with an interest in everyday chemistry.

This reference text describes the breadmaking process at the molecular level, based on surface and colloidal science and introducing colloidal science with a minimum of theory.;Reviewing the current molecular and colloidal knowledge of the chain from wheat grain to bread, the book: discusses the structure of the dough, how a foam is formed during fermentation and how starch gelatinization induces the formation of an open-pore network, such as the bread crumb; covers new results on the gluten structure in bulk and at interfaces, as well as on phase separation in the dough; presents a complete model of all structural transitions from dough mixing to the formation of a bread; details the physicochemical properties of proteins, lipids and carbohydrates in wheat and other cereals, and considers their modes of interaction; and explores recent progress in the shape of biomolecular assemblies, derived from forces and curvature at interfaces.;The text provides nearly 850 citations from the reference literature.

Flatbreads form the heart and soul of a traditional meal in several parts of India. Depending on geographical location, ingredients used and method of preparation there are many varieties of flatbreads. Popular Indians flatbreads include chapatti, paratha/parotta, naan, tandoori roti, kulcha, roomali roti, bhakri, thepla and puranpoli. Chapatti, the Indian counterpart of the western pan bread, is consumed widely as a staple to scoop up curries in Indian meals. Since the last few decades, researchers have turned their attention towards Indian flatbreads and have initiated studies on several aspects like nutrition, quality, staling and preservation. The changing dynamics of flatbread preparation and preservation have inspired many research studies. The Science and Technology of Chapatti and Other Indian Flatbreads collates available knowledge to date in a manner that is useful to students, researchers, food industry professionals, and food-based entrepreneurs alike. Key Features: Illustrated with multiple photographs of different types of Indian flatbreads, steps in preparation of chapatti, analytical instruments used, changes in dough/ chapatti appearance due to browning Includes multiple photographs of different flatbreads in varying stages, from creation to expiration Explores the changing dynamics of flatbread preparation and preservation Discusses the role of flour constituents and added ingredients on end product quality and the need to develop healthier variants With its nine chapters, the book takes the reader through a journey in which the gradual evolution of the preparation and consumption of chapatti and other Indian flatbreads has been explained, emphasizing the need for science and technology to support large scale production to keep up with the growing demand for ready- to- cook and ready-to-eat flatbreads. The book, written in simple but scientific language, covers different aspects ranging from introduction and preparation of flatbreads, the role of individual ingredients, particularly wheat variety and wheat composition, milling technique, dough rheology, quality characteristics of flatbreads and their measurement, to topics including staling and preservation of chapatti/flatbreads, nutritional and quality improvement, mechanization of flatbread production and scope for developing novel flour/ flatbread formulations. The authors, with their wide experience in flatbread science have attempted to capture the scientific and technological aspects of chapatti/flatbreads in depth, right from basic concepts to technological advances, supported by exhaustive compilation of scientific literature.

The dictionary entries, organized in alphabetical order, include information on ingredient functions, chemical properties, and uses in food products. The updated and revised Third Edition contains approximately 1 SO new entries, and includes an updated and expanded bibliography. It also lists food ingredients ac cording to U. S. federal regulatory status. Users of the two previous editions have commented favorably on the dictionary's straightforward and clearly-written definitions, and we have endeavored to maintain that standard in this new edition. We trust it will continue to be a valuable reference for the food scientist, food processor, food product developer, nutritionist, extension specialist, and student. R S. Igoe Y. H.
