Book Description
Freezing time and freezing heat load are the two most important factors determining the economics of food freezers. This Brief will review and describe the principal methods available for their calculation. The methods can be classified into analytical methods, which rely on making physical simplifications to be able to derive exact solutions; empirical methods, which use regression techniques to derive simplified equations from experimental data or numerical calculations and numerical methods, which use computational techniques such as finite elements analysis to solve the complete set of equations describing the physical process. The Brief will evaluate the methods against experimental data and develop guidelines on the choice of method. Whatever technique is used, the accuracy of the results depends crucially on the input parameters such as the heat transfer coefficient and the product's thermal properties. In addition, the estimation methods and data for these parameters will be reviewed and their impacts on the calculations will be evaluated. Freezing is often accompanied by mass transfer (moisture loss, solute absorption), super cooling and nucleation and may take place under high pressure conditions; therefore methods to take these phenomena into account will also be reviewed.

Book Description
The remarkable growth of food technology in industry has been matched by an equal development of related educational programs in food science in colleges and universities in many countries. A vast and growing body of reference books is now available to profes sionals in the field. They have at their fingertips the current state of the art and knowledge in the various areas of specialization embraced by the food industry. For example, excellent reference books are available in the general area of food freezing. The Freezing Preservation of Foods by Tressler et al. is a four volume reference work which covers the subject in detail. Fundamentals of Food Freezing is a book written as a textbook. It repre sents the accumulated art and knowledge in the field of food freezing and draws upon the four volumes of The Freezing Preservation of Foods and the current literature in reference. This new textbook is designed as a unit of instruction in food freezing. As such, it is presented in 16 chapters. The total effect we have attempted to develop is a rounded overall presentation for the student. It is a pleasure to acknowledge the contributions of our many col laborators in preparing this text. These collaborators are identified in the list of contributors; to each, we are most deeply obliged. However, the undersigned are responsible for errors of omission or commission.

Book Description
This book presents a comprehensive range of research on pulsed electric energy used in food processing, including sections on the fundamentals of electroporation and important techniques for the estimation of electroporation effects in various foods and biomass feedstocks. By focusing on application over theory, this book presents researchers with practical steps for processing techniques such as solid-liquid extraction, pressing, osmotic dehydration, drying, freezing and cooking. Special interest is given to the selective recovery and extraction of sugar, inulin, starch, proteins, polysaccharides, polyphenols, pigments, flavor compounds, phytochemicals and other of high-value components from food biomasses such as fruits and vegetables, leaves, herbs, mushrooms, microalgae and suspensions of cells. Processing of Foods and Biomass Feedstocks by Pulsed Electric Energy presents a singular overview of the biorefinery applications of pulsed electric energy for the processing of wastes and non-food biomasses such as root and tuber crops, grape waste, lignocellulosic biomass, oil crops and residues and seeds and peels of exotic and citrus fruits. The book begins by presenting general information on the fundamentals of electroporation and information on the procedures and protocols involved. Further chapters focus on the specific food processing operations involved and biorefinery applications for the processing of wastes and non-food biomasses. All of the relevant and up-to-date information any researcher needs on pulsed electric energy in food processing is presented here in this text.

Book Description
Food Processing Technology: Principles and Practice, Fifth Edition includes emerging trends and developments in food processing. The book has been fully updated to provide comprehensive, up-to-date technical information. For each food processing unit operation, theory and principles are first described, followed by equipment used commercially and its operating conditions, the effects of the operation on micro-organisms, and the nutritional and sensory qualities of the foods concerned. Part I describes basic concepts; Part II describes operations that take place at ambient temperature; Part III describes processing using heat; Part IV describes processing by removing heat; and Part V describes post-processing operations. This book continues to be the most comprehensive reference in the field, covering all processing unit operations in a single volume. The title brings key terms and definitions, sample problems, recommended further readings and illustrated processes. Presents current trends on food sustainability, environmental considerations, changing consumer choices, reduced packaging and energy use, and functional and healthy/plant-based foods Includes highly illustrated line drawings and/or photographs to show the principles of equipment operation and/or examples of equipment that is used commercially Contains worked examples of common calculations
