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.

The biochemistry of food is the foundation on which the research and development advances in food biotechnology are built. In Food Biochemistry and Food Processing, lead editor Y.H. Hui has assembled over fifty acclaimed academicians and industry professionals to create this indispensable reference and text on food biochemistry and the ever-increasing development in the biotechnology of food processing. While biochemistry may be covered in a chapter or two in standard reference books on the chemistry, enzymes, or fermentation of food, and may be addressed in greater depth by commodity-specific texts (e.g., the biotechnology of meat, seafood, or cereal), books on the general coverage of food biochemistry are not so common. Food Biochemistry and Food Processing effectively fills this void. Beginning with sections on the essential principles of food biochemistry, enzymology and food processing, the book then takes the reader on commodity-by-commodity discussions of biochemistry of raw materials and product processing. Later sections address the biochemistry and processing aspects of food fermentation, microbiology, and food safety. As an invaluable reference tool or as a state-of-the-industry text, Food Biochemistry and Food Processing fully develops and explains the biochemical aspects of food processing for scientist and student alike.

Research in the field of the Maillard reaction has developed rapidly in recent years as a result of not only the application of improved analytical techniques, but also of the realisation that the Maillard reaction plays an important role in some human diseases and in the ageing process. The Maillard Reaction: Chemistry, Biochemistry, and Implications provides a comprehensive treatise on the Maillard reaction. This single-author volume covers all aspects of the Maillard reaction in a uniform, co-ordinated, and up-to-date manner. The book encompasses: the chemistry of non-enzymic browning; recent advances; colour formation in non-enzymic browning; flavour and off-flavour formation in non-enzymic browning; toxicological aspects; nutritional aspects; other physiological aspects; other consequences of technological significance; implications for other fields; non-enzymic browning due mainly to ascorbic acid; caramelisation; inhibition of non-enzymic browning in foods; and inhibition of the Maillard reaction in vivo. The Maillard Reaction: Chemistry, Biochemistry, and Implications will be welcomed as an important publication for both new and experienced researchers who are involved in solving the mysteries and complexities of Maillard chemistry and biochemistry. It will also appeal to students, university lecturers, and researchers in a variety of fields, including food science, nutrition, biochemistry, medicine, pharmacology, toxicology, and soil science.

A variety of processing methods are used to make foods edible; to pennit storage; to alter texture and flavor; to sterilize and pasteurize food; and to destroy microorganisms and other toxins. These methods include baking, broiling, cooking, freezing, frying, and roasting. Many such efforts have both beneficial and harmful effects. It is a paradox of nature that the processing of foods can improve nutrition, quality, safety, and taste, and yet occasionally lead to the formation of anti-nutritional and toxic compounds. These multifaceted consequences of food processing arise from molecular interactions among nutrients with each other and with other food ingredients. Since beneficial and adverse effects of food processing are of increasing importance to food science, nutrition, and human health, and since many of the compounds formed have been shown to be potent carcinogens and growth inhibitors in animals, I organized a symposium broadly concerned with the nutritional and toxicological consequences of food processing. The symposium was sponsored by the American Institute of Nutrition (AIN) -Federation of American Societies for Experimental Biology (FASEB) for its annual meeting in Washington, D.C., April 1-5, 1990. Invited speakers were asked to develop at least one of the following topics: 1. Nutrient-nonnutrient interactions between amino acids, proteins, carbohydrates, lipids, minerals, vitamins, tannins, fiber, natural toxicants, etc. 2. Effects of radiation. 3. Thermally induced formation of dietary mutagens, antimutagens, carcinogens, anticarcinogens, antioxidants, and growth inhibitors. 4. Effects of pH on nutritional value and safety.

Developments in the understanding of food protein structure, behaviour and applications continue apace. Many of these have, in the past decade, been reported and evaluated in the series 'Developments in Food Pro teins' , comprising seven volumes, with a total of 55 chapters. The time has now come to re-assess many of the topics reviewed in that series and to add certain others. However, instead of assembling, some what at random, food protein topics from quite disparate fields in indi vidual volumes, we have decided to bring together homogeneous groups of topics, each representing a specific sector of the subject. Under the general theme of 'Progress in Food Proteins' the first of these groups covers 'Biochemistry' . Readers will note that, though six of the topics reviewed in this volume are new, five of them have already featured in 'Developments in Food Proteins'. These last are in active research fields in which new develop ments have been of special significance. In this sense, therefore, they are welcome updates.

This book provides an overview of mitigation strategies and positive health effects of Maillard Reaction products in the contexts of food processing and storage. The effects of Maillard Reactions can vary considerably: while on the one hand certain sensorial alterations and influences on color, flavor and odor may be desirable, Maillard Reactions can also result in potentially harmful and toxic products (e.g. furfurals, furosines, or acrylamide). This book discusses possible mitigation strategies for the reduction of toxic reaction products, including the addition of enzymes or antioxidants, reducing sugars, and encapsulation approaches, as well as new processing strategies, such as high-pressure, radio-frequency, ultrahigh-temperature, or Ohmic heating methods. The book also illustrates that certain Maillard products can even produce positive health effects, e.g. antimicrobial or anticarcinogenic effects. The methods described here can serve as a blueprint for promoting the formation of beneficial compounds and reducing / avoiding toxic substances, offering essential strategies and methods.
