Applied Food Protein Chemistry

Food proteins are of great interest, not only because of their nutritional importance and their functionality in foods, but also for their detrimental effects. Although proteins from milk, meats (including fish and poultry), eggs, cereals, legumes, and oilseeds have been the traditional sources of protein in the human diet, potentially any proteins from a biological source could serve as a food protein. The primary role of protein in the diet is to provide the building materials for the synthesis of muscle and other tissues, and they play a critical role in many biological processes. They are also responsible for food texture, color, and flavor. Today, food proteins are extracted, modified, and incorporated into processed foods to impart specific functional properties. They can also have adverse effects in the diet: proteins, such as walnuts, pecans, almonds, and cashews, soybean, wheat, milk, egg, crustacean, and fish proteins can be powerful allergens for some people. Applied Food Protein Chemistry is an applied reference which reviews the properties of food proteins and provides in-depth information on important plant and animal proteins consumed around the world. The book is grouped into three sections: (1) overview of food proteins, (2) plant proteins, and (3) animal proteins. Each chapter discusses world production, distribution, utilization, physicochemical properties, and the functional properties of each protein, as well as its food applications. The authors for each of the chapters are carefully selected experts in the field. This book will be a valuable reference tool for those who work on food proteins. It will also be an important text on applied food protein chemistry for upper-level students and graduate students of food science programs.

Food Protein Chemistry: An Introduction for Food Scientists discusses food proteins and how they are studied. Proteins are both biological entities and physicochemical compounds, and they will be examined in both contexts in this volume. The chemical and physical properties of proteins will be viewed from the perspective of chemists despite the fact that their use in the food supply emphasizes their biological nature. Key topics discussed include proteins as essential to life; amino acids; protein classification; selected proteins of the most important food systems; and protein structure. The book also includes chapters on protein measurement; protein purification; and spectral techniques for the study of proteins. The book requires readers to have the equivalent of the Institute of Food Technologists requirements for undergraduate food science majors. It also assumes a knowledge of math through calculus. While primarily intended for senior and first-year graduate food science students, the text may also be useful to researchers in allied fields.

Protein chemistry has entered a revolutionary era due to the introduction of genetic engineering for modifying protein structure, as well as the application of advanced computer technology to the study of proteins. By supplementing the traditional ways of studying protein behavior with these newer methods, food processors will be able to resolve difficult problems without using the costly trial-and-error-method so common in the past. This book gives the reader a good foundation in the basics of modern protein chemistry and to show how applications of these concepts to food proteins helps explain their roles in food processing.

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.

A multidisciplinary resource, Food Proteins and Peptides: Chemistry, Functionality, Interactions, and Commercialization enables researchers in biochemistry, biotechnology, food science and technology, nutrition, and medicine to understand the physicochemical and biochemical factors that govern the functionality of these food components. Following chapters on the structure and chemistry of amino acids, peptides, and proteins, the book describes modes of characterization and the functional relationships of food proteins. It examines protein solubility and insolubility and explores proteins and peptides as emulsifying and foaming agents. Specialized topics include: Factors affecting heat-induced casein–whey protein interactions in bovine milk systems The effects of protein–saccharide interactions on the properties of food components Ameliorative action of peptides on cholesterol and lipid metabolism Proteins and peptides with elements of sweetness, kokumi, umami, and bitterness A new approach for the large-scale fractionation of peptides based on their amphoteric nature The book examines the source of bioactive peptides and describes their bioavailability, including their absorption and occurrence in human blood. It also provides a database of biologically active proteins and peptides. Final chapters review current status, future industrial perspectives, and future trends of bioactive food proteins and peptides and explore the role of nanotechnology in protein research. With contributions from a panel of international scientists, this volume captures the state of the art in protein and peptide research, providing a launching pad for further inquiry and discovery.

This book attempts to bridge the two extreme ends of protein science: on one end, systems proteomics, which describes, at a system level, the intricate connection network that proteins form in a cell, and on the other end, protein chemistry and biophysics, which describe the molecular properties of individual proteins and the structural and thermodynamic basis of their interactions within the network. Bridging the two ends of the spectrum is bioinformatics and computational chemistry. Large data sets created by systems proteomics need to be mined for meaningful information, methods need to be designed and implemented to improve experimental designs, extract signal over noise, and reject artifacts, and predictive methods need to be worked out and put to the test.
