Book Description
Food proteins constitute a diverse and complex collection of biological macro molecules. Although contributing to the nutritional quality of the foods we con sume, proteins also act as integral components by virtue of their diverse functional properties. The expression of these functional properties during the preparation, processing and storage of foods is largely dictated by changes to the structure or structure-related properties of the proteins involved. Therefore, germane to the optimal use of existing and future food protein sources is a thorough understanding of the nature of the relationships between structure and function. It is the goal of this book to aid in better defining these relationships. Two distinct sections are apparent: firstly, those chapters which address struc ture-function relationships using a variety of food systems as examples to demonstrate the intricacies of this relationship, and secondly, those chapters which discuss techniques used to either examine structural parameters or aid in establishing quantitative relationships between protein structure and function. The editors would like to thank all contributors for their assistance, co-operation and, above all, their patience in putting this volume together, and the following companies/organizations for their financial support without which it would not have been the success it was: Ault Foods Limited, Best Foods Canada Limited, Natural Sciences and Engineering Research Council of Canada, Ontario Ministry of Agriculture and Food, Quest International Canada Inc., and University of Guelph.

Book Description
Although many pursue understanding of the relationship between protein structure and function for the thrill of pure science, the pay-off in a much broader sense is the ability to manipulate the Earth's chemistry and biology to improve the quality of life for mankind. Immediately goals of this area of research include identification of the life-supporting functions of proteins, and the fundamental forces that facilitate these functions. Upon reaching these goals, we shall have the understanding to direct and the tools required to implement changes that will dramatically improve the quality of life. For example, under standing the chemical mechanism of diseases will facilitate development of new therapeutic drugs. Likewise, understanding of chemical mechanisms of plant growth will be used with biotechnology to improve food production under adverse climatic conditions. The challenge to understand details of protein structure/function relationships is enormous and requires an international effort for success. To direct the chemistry and biology of our environment in a positive sense will require efforts from bright, imaginative scientists located throughout the world. Although the emergence of FAX, e-mail, and the World Wide Web has revolutionized international communication, there remains a need for scientists located in distant parts of the world to occasionally meet face to face.

Book Description
The functional properties of food proteins affect behavior in food systems and influence the quality attributes, structure, texture, mouth-feel, and flavor of the final product. These attributes are precisely those with which food engineers and technologists are concerned when developing new products. This innovative book provides an overview of the physical properties of proteins and how dynamic changes in conformation, structural changes, and protein-protein interactions are involved in the performance of particular functional properties such as gelation, emulsification, and foaming properties. Models used include B-Lactoglobulin, soy, and meat proteins.

Book Description
This book discusses the chemistry of food proteins and peptides and their relationship with nutritional, functional, and health applications. Bringing together authorities in the field, it provides a comprehensive discussion focused on fundamental chemistries and mechanisms underpinning the structure-function relationships of food proteins and peptides. The functional and bioactive properties hinge on their structural features such as amino acid sequence, molecular size, hydrophobicity, hydrophilicity, and net charges. The book includes coverage of advances in the nutritional and health applications of protein and peptide modifications; novel applications of food proteins and peptides in the development of edible functional biomaterials; advances in the use of proteomics and peptidomics for food proteins and peptide analysis (foodomics); and the relevance of food protein and peptide chemistries in policy and regulation. Research into the fundamental chemistries behind the functional, health and nutritional benefits is burgeoning and has gained the interest of scientists, the industry, regulatory agencies, and consumers. This book fills the knowledge gap providing an excellent source of information for researchers, instructors, students, food and nutrition industry, and policy makers.

Book Description
Chemical and Functional Properties of Food Proteins presents the current state of knowledge on the content of proteins in food structures, the chemical, functional, and nutritive properties of food proteins, the chemical and biochemical modification of proteins in foods during storage and processing, and the mutagenicity and carcinogenicity of nitrogenous compounds. It emphasizes the structure-function relationship as well as the effects of practical conditions applied in food processing on the biochemical and chemical reactions in food proteins and food product quality. The first ten chapters discuss structure-function relationships, methods of analysis of nitrogenous compounds, chemical and enzymatic modifications, nutritive roles, and mutagenicity and carcinogenicity of food proteins. The following six chapters describe the proteins of meat and fish, milk, eggs, cereals, legumes, oilseeds and single cell organisms, and present detailed information on the effects of conditions applied in storage and processing on the reactions in proteins and their impact on quality attributes of food products.

Book Description
The book is devoted to expanding current views on the phenomena of protein functionality in food systems. Protein functionalities in foods have been the object ofextensive research over the last thirty to forty years and significant progress has been made in understanding the mechanism and factors influencing the functionality of proteins. The functionality of proteins is one of the fastest developing fields in the studies of protein utilization in foods. Currently, a broad spectrum of data related to protein functionality in food systems has been collected, however, much more needs to be known. In this volume, the most important functional properties offood proteins are presented: Protein solubility, water holding capacity and fat binding, emulsifying, foaming, and gelling properties as affected by protein source, environmental factors (pH, temperature, ionic strength) and protein concentration; Relationships between protein conformation, physicochemical properties, and functional properties; Protein functional properties as influenced by various food processing conditions, particularly heat treatment, dehydration, freezing and storage when frozen, extraction and other processes; Effects ofprotein modification on the enhancementofprotein functionality; Utilization ofvarious proteins in improving functional properties in food systems. Those aspects of protein functionality are presented which the author believes to be interesting and most important for protein utilization in food systems. The book is recommended to students and food scientists engaged in food protein research and food industry research, and development scientists.
