Physical Chemical Properties Of Foods

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

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.

This is the first textbook in this field of increasing importance for the food and cosmetics industries. It is indispensable for future students of food technology and food chemistry as well as for engineers, technologists and technicians in the food industries. It describes the principles of food physics starting with the very basics – and focuses on the needs of practitioners without omitting important basic principles. It will be indispensable for future students of food technology and food chemistry as well as for engineers, technologists and technicians in the food industries. Food Physics deals with the physical properties of food, food ingredients and their measurement.

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.

This book is an invaluable introduction to the physical properties of foods and the physics involved in food processing. It provides descriptions and data that are needed for selecting the most appropriate equipment in food technology and for making food processing calculations.

With higher food quality in increasing demand by consumers, there is continuous pressure on food engineers to meet market needs. One of the critical challenges is to use modern technology and knowledge to develop new processes for improving food quality. Given the global food marketplace, there is also a greater need for a means of objectively clas
