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.

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.

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 Second Edition of Food Process Engineering by Dr. Dennis Heldman, my former student, and co-author Paul Singh, his former student, attests to the importance of the previous edition. In the Foreword to the First Edition, I noted the need for people in all facets of the food processing industry to consider those variables of design of particular importance in engineering for the food processing field. In addition to recognizing the many variables involved in the biological food product being handled from production to consumption, the engi neer must oftentimes adapt equations developed for non-biological materials. As more and more research is done, those equations are appropriately modified to be more accurate or new equations are developed specifically for designing to process foods. This Edition updates equations used. This book serves a very important need in acquainting engineers and technologists, particularly those with a math ematics and physics background, with the information necessary to provide a more efficient design to accomplish the objectives. Of prime importance, at present and in the future, is to design for efficient use of energy. Now, it is often economical to put considerably more money into first costs for an efficient design than previously, when energy costs were a much smaller proportion of the total cost of process engineering.

Ten years after the publication of the first edition of Fundamentals of Food Process Engineering, there have been significant changes in both food science education and the food industry itself. Students now in the food science curric ulum are generally better prepared mathematically than their counterparts two decades ago. The food science curriculum in most schools in the United States has split into science and business options, with students in the science option following the Institute of Food Technologists' minimum requirements. The minimum requirements include the food engineering course, thus students en rolled in food engineering are generally better than average, and can be chal lenged with more rigor in the course material. The food industry itself has changed. Traditionally, the food industry has been primarily involved in the canning and freezing of agricultural commodi ties, and a company's operations generally remain within a single commodity. Now, the industry is becoming more diversified, with many companies involved in operations involving more than one type of commodity. A number of for mulated food products are now made where the commodity connection becomes obscure. The ability to solve problems is a valued asset in a technologist, and often, solving problems involves nothing more than applying principles learned in other areas to the problem at hand. A principle that may have been commonly used with one commodity may also be applied to another commodity to produce unique products.

Provides directions for preserving fruit, vegetables, and meat using the methods of pickling, freezing, bottling, drying, salting, and curing.

Preserving food is hot! The local food movement gains even more popularity as consumers return to vegetable gardening to grow their own food. They increasingly have become interested in the techniques for “putting up” their bounty. Driven by the recession; the need for healthier, chemical-free food,and taste, people everywhere are preserving the abundance of fruits, vegetables, and herbs harvested from their garden (or someone else’s). You don’t even have to grow your own to preserve freshness; non-gardeners too are learning to preserve with locally grown produce bought from local markets. Targeted at anyone who wants to capture the flavor of freshness, whether it’s from making tomato sauce, drying herbs, or preserving jams and jellies.

Frozen foods make up one of the biggest sectors in the food industry. Their popularity with consumers is due primarily to the variety they offer and their ability to retain a high standard of quality. Thorough and authoritative, the Handbook of Frozen Food Processing and Packaging provides the latest information on the art and science of cor

This book presents a comprehensive, integrated view of quality in frozen foods. It addresses quality from a number of perspectives: technological (mechanical and cryogenic methods of freezing); categorical (classification of quality loss); analytical (measurement of quality); theoretical (model building); applied (preventative treatments), and administrative (policy). The book focuses on the principles of freezing and the concepts of quality, and is therefore applicable to research and development of all types of products. Features include: technological and fundamental features of freezing; types of deterioration that occur in frozen foods; treatment to minimize quality losses during freezing and storage; methods to assess quality losses; strategies that impact a frozen product's quality and ultimate consumer acceptance.
