Introduction To The Physical Chemistry Of Foods

Familiar combinations of ingredients and processing make the structures that give food its properties. For example in ice cream, the emulsifiers and proteins stabilize partly crystalline milk fat as an emulsion, freezing (crystallization) of some of the water gives the product its hardness and polysaccharide stabilizers keep it smooth. Why different recipes work as they do is largely governed by the rules of physical chemistry. This textbook introduces the physical chemistry essential to understanding the behavior of foods. Starting with the simplest model of molecules attracting and repelling one another while being moved by the randomizing effect of heat, the laws of thermodynamics are used to derive important properties of foods such as flavor binding and water activity. Most foods contain multiple phases and the same molecular model is used to understand phase diagrams, phase separation and the properties of surfaces. The remaining chapters focus on the formation and properties of specific structures in foods – crystals, polymers, dispersions and gels. Only a basic understanding of food science is needed, and no mathematics or chemistry beyond the introductory college courses is required. At all stages, examples from the primary literature are used to illustrate the text and to highlight the practical applications of physical chemistry in food science.

Introduction to the Physical Chemistry of Foods provides an easy-to-understand text that encompasses the basic principles of physical chemistry and their relationship to foods and their processing. Based on the author’s years of teaching and research experience in the physical chemistry of food, this book offers the necessary depth of information and mathematical bases presented in a clear manner for individuals with minimal physical chemistry background. The text begins with basic physical chemistry concepts, building a foundation of knowledge so readers can then grasp the physical chemistry of food, including processes such as crystallization, melting, distillation, blanching, and homogenization as well as rheology and emulsion and foam stability. The chapters cover thermodynamic systems, temperature, and ideal gases versus real gases; chemical thermodynamics and the behavior of liquids and solids, along with phase transitions; and the thermodynamics of small molecule and macromolecule dispersions and solutions. The text describes surface activity, interfaces, and adsorption of molecules. Attention is paid to surface active materials, with a focus on self-assembled and colloidal structures. Emulsions and foams are covered in a separate chapter. The book also introduces some of the main macroscopic manifestations of colloidal (and other) interactions in terms of rheology. Finally, the author describes chemical kinetics, including enzyme kinetics, which is vital to food science. This book provides a concise, readable account of the physical chemistry of foods, from basic thermodynamics to a range of applied topics, for students, scientists, and engineers with an interest in food science.

Exploring the structure and physical and chemical properties of solutions, dispersions, soft solids, fats, and cellular systems, Physical Chemistry of Foods describes the physiochemical principles of the reactions and conversions that occur during the manufacture, handling, and storage of foods. Coverage progresses from aspects of thermodynamics, bonds and interaction forces, and reaction kinetics, to transport phenomena, polymers, colloidal interactions, nucleation, glass transitions and freezing, and soft solids. This comprehensive volume effectively clarifies the physicochemical processes encountered in food product development.

Introduction to the Chemistry of Food describes the molecular composition of food and the chemistry of its components. It provides students with an understanding of chemical and biochemical reactions that impact food quality and contribute to wellness. This innovative approach enables students in food science, nutrition and culinology to better understand the role of chemistry in food. Specifically, the text provides background in food composition, demonstrates how chemistry impacts quality, and highlights its role in creating novel foods. Each chapter contains a review section with suggested learning activities. Text and supplemental materials can be used in traditional face-to-face, distance, or blended learning formats. Describes the major and minor components of food Explains the functional properties contributed by proteins, carbohydrates and lipids in food Explores the chemical and enzymatic reactions affecting food attributes (color, flavor and nutritional quality) Describes the gut microbiome and influence of food components on its microbial population Reviews major food systems and novel sources of food protein
