While introducing the principles and processes of industrial-level food canning, the volume clarifies the effects of microorganisms, their ecology, fate, and prevention in canning operations, as well as in other thermal processing techniques, such as aseptic packaging. It covers microbial spoilage and detection for vegetables, fruits, milk, meat and seafood from the raw food materials through individual unit operations, facility sanitation, and packaging. It thus offers a practical introduction to understanding, preventing and destroying microbe-based hazards in food plants that use thermal processes to preserve and package foods. The text surveys major spoilage and pathogenic microbes of interest, explaining their toxicity, product and safety effects, and the conditions of their destruction by heat treatment.

Thermal processing remains the most important method of food preservation in use today, and the scale of the industry is immense. The large scale of these production operations makes it more important than ever that the process is performed perfectly every time: failure will lead to product deterioration and loss of sales at best, and at worst to serious illness or death. This volume is a definitive modern-day reference for all those involved in thermal processing. It covers all of the essential information regarding the preservation of food products by heat. It includes all types of food product, from those high in acid and given a mild heat process to the low-acid sterilised foods that require a full botulinum cook. Different chapters deal with the manufacturing steps from raw material microbiology, through various processing regimes, validation methods, packaging, incubation testing and spoilage incidents. The authors have extensive knowledge of heat preservation covering all parts of the world and represent organisations with formidable reputations in this field. This book is an essential resource for all scientists and technologists in the food manufacturing industry as well as researchers and students of food science and technology.

This Brief describes the chemical features of canned food products and gives background information on the technology of canning foods. It explains how canned foods are different from other packaged foods, and illustrates and discusses their unique properties, including risks and failures. Canned foods are usually considered to offer a particularly long shelf-life and durability. An understanding of their properties and influences on their durability is therefore of great importance in the industrial production, and this Brief offers a compact introduction to this topic. The authors focus on thermally-preserved foods. They explain that the right choice of thermal treatment method (e.g. pasteurisation, sterilisation) as well as process parameters (e.g. time, temperature) is additionally influenced by criteria such as pH, water content, the presence and concentration of fatty molecules, of calcium, etc. So-called ‘survival curves’ can help in determining the methodology of choice, and the Brief introduces the reader to this concept. The authors also address defects and failures. They introduce selected indicators, which can help identifying failures of the entire food/packaging system, and demonstrate how image and visual analysis can be applied in quality controls. The explanations and industrial production of canned foods are exemplified with the case of canned tomato sauces and beans.

Thermobacteriology in Food Processing, Second Edition focuses on the principles involved in sterilization processes for canned goods and pasteurization of foods. The book first ponders on organisms of greatest importance in the spoilage of canned foods and food pasteurization and bacteriological examination of spoiled canned foods. Discussions focus on toxin-producing microorganisms, pathogenic microorganisms, bacteriological examination, classification of spore-bearing bacteria with reference to oxygen requirements, classification of food with respect to acidity, and interpretation of observations. The text then takes a look at contamination and its control, producing, harvesting, and cleaning spores for thermal resistance determinations, and death of bacteria subjected to moist heat. The manuscript tackles thermal resistance of bacteria and thermal process evaluation, including important terms and equations, basic considerations, general method, and conversion of heat penetration data. Topics include change of initial food temperature when the retort temperature remains the same, integrated lethality of heat at all points in the container, heat penetration and processing parameters, and determination of process lethality requirement. The publication is a valuable reference for researchers interested in thermobacteriology in food processing.

Advances in Thermal and Non-Thermal Food Preservation provides current, definitive and factual material written by experts on different thermal and non-thermal food preservation technologies. Emphasizing inactivation of microorganisms through the application of traditional as well as newer and novel techniques and their combinations, the book’s chapters cover: thermal food preservation techniques (e.g., retorting, UHT and aseptic processing), minimal thermal processing (e.g., sous-vide processing), and non-thermal food preservation techniques (e.g., high pressure processing and pulsed technologies). Editors Tewari and Juneja give special emphasis to the commercial aspects of non-conventional food preservation techniques. As the most comprehensive and contemporary resource of its kind, Advances in Thermal and Non-Thermal Food Preservation is the definitive standard in describing the inactivation of microorganisms through conventional and newer, more novel techniques.
