Sterilization of Food in Retort Pouches


Book Description

The subject of sterilization of food in cans has been studied both experimentally and theoretically, but limited work has been undertaken to study the sterilization of food in pouches. This book examines the interaction between fluid mechanics, heat transfer and microbial inactivation during sterilization of food in pouches. Such interaction is complex and if ignored would lead to incorrect information not only on food sterility but also on food quality.




Principles of Food Processing


Book Description

The approach to teaching the concepts of food processing to the undergrad uate food science major has evolved over the past 40 years. In most under graduate food science curricula, food processing has been taught on a commodity basis. In many programs, several courses dealt with processing with emphasis on a different commodity, such as fruits and vegetables, dairy products, meat products, and eggs. In most situations, the emphasis was on the unique characteristics of the commodity and very little empha sis on the common elements associated with processing of the different commodities. Quite often the undergraduate student was allowed to select one or two courses from those offered in order to satisfy the minimum standards suggested by the Institute of Food Technologists. The current 1FT minimum standards suggest that the undergradu ate food science major be required to complete at least one food processing course. The description of this course is as follows: One course with lecture and laboratory which covers general characteristics of raw food materials, principles offood preserva tion, processing factors that influence quality, packaging, water and waste management, and sanitation. Prerequisites: general chemistry, physics, and general microbiology.




Conventional and Advanced Food Processing Technologies


Book Description

Food processing technologies are an essential link in the food chain. These technologies are many and varied, changing in popularity with changing consumption patterns and product popularity. Newer process technologies are also being evolved to provide the added advantages. Conventional and Advanced Food Processing Technologies fuses the practical (application, machinery), theoretical (model, equation) and cutting-edge (recent trends), making it ideal for industrial, academic and reference use. It consists of two sections, one covering conventional or well-established existing processes and the other covering emerging or novel process technologies that are expected to be employed in the near future for the processing of foods in the commercial sector. All are examined in great detail, considering their current and future applications with added examples and the very latest data. Conventional and Advanced Food Processing Technologies is a comprehensive treatment of the current state of knowledge on food processing technology. In its extensive coverage, and the selection of reputed research scientists who have contributed to each topic, this book will be a definitive text in this field for students, food professionals and researchers.

Continuous Thermal Processing of Foods: Pasteurization and UHT Sterilization


Book Description

This new book updates and expands Harold Burton's classic book, UHT Processing of Milk and Milk Products, to provide comprehensive, state-of-the-art coverage of thermal processing of liquid and particulate foods. The food products covered now include soups, sauces, fruit juices, and other beverages, in addition to milk and milk products. Pasteurization, sterilization, and aseptic processing are all discussed, with emphasis on the underlying principles and problems of heat treatment of more viscous fluids, where streamline flow conditions are likely to prevail, and of products containing particles. Pasteurization and heat treatments designed to further extend the shelf life of pasteurized products are also discussed, and the pasteurization and sterilization processes are compared to highlight similarities and differences. Throughout, factors influencing the safety and quality of heated foods are emphasized. This book contains over 100 illustrations and 50 tables, as well as extensive cross-referencing and a comprehensive reference section.




Thermobacteriology in Food Processing


Book Description

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.
