Biodeterioration is the breakdown of food by agents of microbiological origin, either directly or indirectly from products of their metabolism. Preservation on the other hand is the process by which food materials are maintained in their original condition or as close to this as possible. This second edition of Food Preservation and Biodeterioration is fully updated and reorganised throughout. It discusses how the agents of food biodeterioration operate and how the commercial methods available to counteract these agents are applied to produce safe and wholesome foods. With this book, readers will discover traditional methods as well as major advances in preservation technology. Both microbiological and chemical pathways are analysed. This topic being important to all producers of food, the readership spans food scientists across industry and academia, particularly those involved with safety and quality.

Food Preservation and Biodeterioration

[b]ESSENTIALS OF THERMAL PROCESSING[/b] [b]Explore this fully updated new edition of a practical reference on food preservation from two leading voices in the industry[/b]Among all food preservation methods in use today, thermal processing remains the single most important technique used in the industry. The newly revised Second Edition of [i]Essentials of Thermal Processing[/i] delivers a thorough reference on the science and applications of the thermal processing of a wide variety of food products. The book offers readers essential information on the preservation of food products by heat, including high-acid foods and low-acid sterilized foods requiring a full botulinum cook.The accomplished authors—noted experts in their field—discuss all relevant manufacturing steps, from raw material microbiology through the various processing regimes, validation methods, packaging, incubation testing, and spoilage incidents.Two new chapters on temperature and heat distribution, as well as heat penetration of foods, are included. More worked and practical examples are found throughout the book as well. Readers will also benefit from the inclusion of:A thorough introduction to the microbiology of heat processed foods, food preservation techniques, low acid canned foods, and high acid foodsAn exploration of acidified products, heat extended shelf-life chilled foods, and processing methodsDiscussions of cooking and process optimization, process validation, and heat penetration and process calculationsAn examination of cooling and water treatment, how to handle process deviations, and packaging options for heat preserved foodsPerfect for professionals working in the food processing and preservation industries, [i]Essentials of Thermal Processing[/i] will also earn a place in the libraries of anyone seeking a one-stop reference on the subject of thermal processing for food products.

Essentials of Thermal Processing

Biodeterioration can be defined as the breakdown of food by agents of microbiological origin, either directly or from products of their metabolism. Microbiological sources can be present in foods prior to packaging or on the surfaces of packaging materials. The shelf life and safety of the food will depend on the type and quantity of microorganism, as well as the hurdles to their growth offered by various preservation techniques. This book discusses how the agents of food biodeterioration operate, and examines the commercially-used industrial methods available to control them, allowing the production of safe and wholesome foods. There is an emphasis on the equipment employed to carry out the various methods of preservation. The introductory chapter describes in detail the microorganisms and mechanisms of food breakdown intrinsic to various key food types; dairy, meat and fish, fruit, and vegetables. Direct microorganism action will be covered in addition to enzymatic breakdown. The second chapter addresses HACCP, including food safety legislation. Subsequent chapters outline the principal, commercially-used methods of preserving foods. These chapters follow a common structure: theoretical background; flow sheets of operations; food preparation/processing equipment; special features of hygiene; packaging; shelf life; and product safety. Food Biodeterioration and Preservation is directed at food scientists and technologists in industry and academia. Since it covers all the commonly-used methods of food preservation, it will be relevant across the entire food manufacturing industry.
