Fundamentals Of Food Freezing

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.

This book provides a comprehensive source of information on freezing and frozen storage of food. Initial chapters describe the freezing process and provide a fundamental understanding of the thermal and physical processes that occur during freezing. Experts in each stage of the frozen cold chain provide, within dedicated chapters, guidelines and advice on how to freeze food and maintain its quality during storage, transport, retail display and in the home. Individual chapters deal with specific aspects of freezing relevant to the main food commodities: meat, fish, fruit and vegetables. Legislation and new freezing processes are also covered. Frozen Food Science and Technology offers in-depth knowledge of current and emerging refrigeration technologies along the entire frozen food chain, enabling readers to optimise the quality of frozen food products. It is aimed at food scientists, technologists and engineers within the frozen food industry; frozen food retailers; and researchers and students of food science and technology.

An accessible guide to safely dehydrating food Freeze drying, or lyophilization, is a method for dehydrating food or other substances through the use of pressure instead of heat. This allows for the preservation and storage of high-value food products without altering their essential properties or causing a reduction in quality or value. For these reasons, freeze drying is the most reliable method for preserving and distributing high-quality products. Freeze Drying of Food Products provides a concise, accessible overview of freeze-drying techniques and their modern applications. Beginning with the basic principles and processes of freeze drying, it incorporates specific discussion of freeze-drying different categories of food products, before moving to an analysis of recent developments in freeze-drying technology. The result is a key publication in the fight to extend the shelf-life of food products and expand the distribution of high-quality freeze-dried foods. Freeze Drying of Food Products readers will also find: An editorial team with a wide range of pertinent research experience Detailed discussion of different freeze-drying processes such as vacuum drying, atmospheric drying, and spray drying Commercial Applications of freeze-dried food products Freeze Drying of Food Products is ideal for researchers and industry professionals involved in food production, food distribution, or food biotechnology, as well as students studying these and other related fields.

The ultimate how-to guide to storing food in your freezer—how long to store, how to prepare for storage, and how to thaw out over 200 kinds of foodstuffs. In this sequel to her Basic Basics Combination & Microwave Handbook, Carol Bowen offers more handy kitchen and culinary advice with an easy to follow, encyclopedic layout. Simply look up the fruit, vegetable, fish, meat, sauces, cakes, or herbs of your choice to find the correct guidelines on freezing each type of food. Bowen also explains the technical aspects of how freezers work, gives advice on choosing and positioning your freezer, and covers topics such as freezer insurance, cleaning, maintenance, emergencies, packaging, and accessories. You will also learn techniques for freezing, defrosting, refreezing, and thawing, as well as storage times. These days, making the most of your food budget is more important than ever. And with The Basic Basics Home Freezing Handbook, you’ll save both food and money with any meal!

This work presents a comprehensive overview of existing knowledge regarding the influence of freezing, frozen storage and thawing of specific food-stuffs. It delineates how freezing processes alter the colour, appearance, palatability, nutritional value, intrinsic chemical reactions, microbiological safety and consumer acceptance of foods. The fundamental concepts upon which food-freezing technologies are based, are reviewed.

Written for the upper level undergraduate, this updated book is also a solid reference for the graduate food engineering student and professional. This edition features the addition of sections on freezing, pumps, the use of chemical reaction kinetic date for thermal process optimization, and vacuum belt drying. New sections on accurate temperature measurements, microbiological inactivation curves, inactivation of microorganisms and enzymes, pasteurization, and entrainment are included, as are non-linear curve fitting and processes dependent on fluid film thickness. Other sections have been expanded.
