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.

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!

Freeze-drying is an important preservation technique for heat-sensitive pharmaceuticals and foods. Products are first frozen, then dried in a vacuum at low temperature by sublimation and desorption, rather than by the application of heat. The resulting items can be stored at room temperature for long periods. This informative text addresses both principles and practice in this area. The first chapter introduces freeze-drying. The authors then review the fundamentals of the technique, heat-mass transfer analyses, modelling of the drying process and the equipment employed. Further chapters focus on freeze-drying of food, freeze-drying of pharmaceuticals and the protective agents and additives applied. The final chapter covers the important subjects of disinfection, sterilization and process validation. Freeze-drying of pharmaceutical and food products is an essential reference for food, pharmaceutical and refrigeration engineers and scientists with an interest in preservation techniques. It will also be of use to students in these fields. Addresses the principles and practices used in this important preservation technique Explains the fundamentals of heat-mass transfer analysis, modelling and the equipment used Discusses the importance of disinfection, sterilization and process validation

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.

The publication of this book has been perfectly timed to serve the needs of a rapidly expanding industry. Frozen foods have shed their associations with low quality convenience food and freezing is now recognised as one of the safest and most nutritionally valuable ways to store food. Quality is a fundamental competitive advantage. However, the quality of frozen foods is dependent upon the strength or weakness of each link in the supply chain. This book examines the key quality factors at each stage in the frozen food supply chain, from raw material selection through processing and storage to retail display. Managing frozen foods is a unique overview of this entire industry and provides frozen food manufacturers, distributors and retailers with: The book begins with a review of the safety of frozen foods in production and distribution. It then considers the selection of raw materials and pre-treatment before examining the range of physical and chemical factors affecting the sensory and nutritional quality of food during freezing. This is followed by a comprehensive review of freezer technology and identifies the essential selection criteria that food manufacturers need to consider. Further chapters discuss the selection of packaging, cold store design, equipment and maintenance as well as the key area of retail display equipment. Dr Christopher J Kennedy concludes the book by providing a valuable insight into the future of this industry, outlining the opportunities offered by latest developments such as anti-freeze proteins and ultrasonic techniques. A practical and authoritative guide to best practice in maximising quality An invaluable decision-making tool, including guidance on the selection of raw materials, freezer technology, packaging materials and retail display equipment The latest research into the frozen food industry from academic and industry experts
