Book Description
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.

Book Description
This resource provides effective mechanistic methods for analyzing and understanding physical and chemical behaviour in foods, and explains how to manipulate and control such behaviour during food processing, distribution and use.;Written by 23 authorities in the field, Physical Chemistry of Foods: treats factors controlling crystallization, cross-linking reactions, dispersion and surface-adsorption processes in foods and clarifies how to modify crystal size distribution, stabilize dispersions and minimize fouling; explores uptake competition between mineral nutrients - offering guidelines for efficient uptake and absorption; describes kinetic rate-controlling steps in Maillard reactions - examining how to manipulate Maillard browning; discusses how gels form and instrumental methods of following gelling processes and covers how to create gel-based textures and structures in foods; considers factors that control the behaviour of bread during dough development, proofing, and baking - showing how carbon dioxide release affects loaf expansion; and reveals how glass transitions affect rheological and kinetic behaviour and transport processes in foods - detailing how to manipulate glass transitions and product behaviour by changes in composition and water content.;Food scientists and technologists; food, agricultural and bioresource engineers; physical and surface chemists; nutritionists; and upper-level undergraduate and graduate students and industrial trainees in these disciplines will repeatedly find valuable new insights and approaches for dealing with practical and theoretical problems and a wealth of useful information in Physical Chemistry of Foods, with its more than 1380 literature citations.

Book Description
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.

Book Description
This book provides a fundamental understanding of physical properties of foods. It is the first textbook in this area and combines engineering concepts and physical chemistry. Basic definitions and principles of physical properties are discussed as well as the importance of physical properties in the food industry and measurement methods. In addition, recent studies in physical properties are summarized. The material presented is helpful for students to understand the relationship between physical and functional properties of raw, semi-finished, and processed food in order to obtain products with desired shelf-life and quality.

Book Description
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

Book Description
The physical and chemical properties of food products have central roles in biotechnology and the pharmaceutical and food industries. Understanding these properties is essential for engineers and scientists to tackle the numerous issues in food processing, including preservation, storage, distribution and consumption.This book discusses models to predict some of the physical-chemical properties (pH, aw and ionic strength) for biological media containing various solutes. In recent years, food production has involved less processing and fewer additives or preservatives. If health benefits for consumers are obvious, it is not only necessary to adapt current processing and preservation processes but also to verify that appropriate technological and health properties are preserved.The authors present established models, but also introduce new tools for prediction with modeling methods that are part of a more general approach to understand the behavior of fluid mixtures and design new products or processes through numerical simulation. Describes the construction of a tool to allow you to predict the physical-chemical properties of foods and bacterial broths Shows you how to apply this tool with complex medias to predict water activity and pH levels and how to integrate this tool with a process simulator Full with theoretical equations and examples to help you apply the content to your data
