Freezing Effects On Food Quality

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 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.

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.

Hui, a technology consultant, presents material on frozen food science, technology, and engineering, describing the manufacture, processing, inspection, and safety of frozen foods. He outlines basic procedures for optimizing the quality and texture of frozen foods and includes and tables and examples that illustrate the effects of various chemical and biochemical reactions on the quality of frozen food. The book details methods for selecting the most appropriate packaging materials for frozen foods, and provides guidelines on ensuring product safety.

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

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.

The Handbook of Meat, Poultry and Seafood Quality commences with a discussion of basic scientific factors responsible for the quality of fresh, frozen and processed muscle foods, especially sensory attributes and flavors. Following sections discuss factors affecting the quality of beef, pork, poultry, and seafood. Under each muscle food, some or all of the following factors affecting the quality are discussed:.:.; additives.; aroma.; color.; contaminants.; flavors.; microbiology.; moisture.; mouthfeel.; nutrition.; packaging.; safety.; sensory attributes.; shelf-life.; stability.; tainting.; t.
