Physical Principles Of Food Preservation

This reference examines the properties, conditions, and theoretical principles governing the safety and efficacy of various food preservation, storage, and packaging techniques. The book analyzes methods to predict and optimize the nutrition, texture, and quality of food compounds while reducing operating cost and waste. The Second Edition contains new chapters and discussions on non-thermal processes; the mechanisms of heat transfer, including conduction, convection, radiation, and dielectric and microwave heating; the kinetic parameters of food process operations; freezing technology, using illustrative examples; recent breakthroughs in cryochemistry and cryobiology, and more.

This book covers application of food microbiology principles into food preservation and processing. Main aspects of the food preservation techniques, alternative food preservation techniques, role of microorganisms in food processing and their positive and negative features are covered. Features subjects on mechanism of antimicrobial action of heat, thermal process, mechanisms for microbial control by low temperature, mechanism of food preservation, control of microorganisms and mycotoxin formation by reducing water activity, food preservation by additives and biocontrol, food preservation by modified atmosphere, alternative food processing techniques, and traditional fermented products processing. The book is designed for students in food engineering, health science, food science, agricultural engineering, food technology, nutrition and dietetic, biological sciences and biotechnology fields. It will also be valuable to researchers, teachers and practising food microbiologists as well as anyone interested in different branches of food.

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.

The processing of food is no longer simple or straightforward, but is now a highly inter-disciplinary science. A number of new techniques have developed to extend shelf-life, minimize risk, protect the environment, and improve functional, sensory, and nutritional properties. The ever-increasing number of food products and preservation techniques cr

Completely up-to-date and organized for easy use, this one-of-a-kind reference integrates basic concepts with hands-on techniques for food dehydration. It discusses a wide range of scientific and technical information, from the physical, chemical, and microbiological changes in food dehydration to its packaging aspects.
