Glass Transition and Phase Transitions in Food and Biological Materials


Book Description

Glass and State Transitions in Food and Biological Materials describes how glass transition has been applied to food micro-structure, food processing, product development, storage studies, packaging development and other areas. This book has been structured so that readers can initially grasp the basic principles and instrumentation, before moving through the various applications. In summary, the book will provide the “missing link” between food science and material science/polymer engineering. This will allow food scientists to better understand the concept and applications of thermal properties.




Phase Transitions in Foods


Book Description

Assembling recent research and theories, this book describes the phase and state transitions that affect technological properties of biological materials occurring in food processing and storage.

The volume presents methods for detecting changes in the physical state and various techniques used to analyze phase behavior of biopolymers and food components. This book should become a valuable resource for anyone involved with food engineering, processing, storage, and quality, as well as those working on related properties of pharmaceuticals and other biopolymers. - Contains descriptions of nonfat food solids as"biopolymers"which exhibit physical properties that are highly dependent on temperature, time, and water content - Details the effects of water on the state and stability of foods - Includes information on changes occuring in state and physicochemical properties during processing and storage - The only book on phase and state transitions written specifically for the applications in food industry, product development, and research - No recent competition




The Glass Transition


Book Description

Non-Equilibrium States and Glass Transitions in Foods


Book Description

Non-equilibrium States and Glass Transitions in Foods: Processing Effects and Product Specific Implications presents the tactics needed to understand and control non-equilibrium states and glass transitions in food, an essential element in maintaining the shelf-life and quality of foods. After brief introductory chapters introduce the science behind non-equilibrium states and glass transitions in foods, the book details how glass transition temperature is affected by composition and the ways it influences processability and physico-chemical changes during the storage of foods, also exploring how these effects can be controlled. The second section looks at individual foods, highlighting the implications of non-equilibrium states and glass transitions within these foods. Maintaining and improving the quality of food is of upmost importance to food companies who have to ensure that the shelf life of their products is as long as possible. A large amount of research has been performed into glass transitions in food over the last few years, however there has not been a comprehensive review. This book fills that gap.
