Determining accurate shelf life data for foods is essential for assuring food quality and protecting consumers from the effects of degradation. With a proper balance of theory and practical examples, Shelf Life Assessment of Food presents the essential criteria and current methodologies for obtaining accurate and reliable shelf life dating. Defining the process through a series of sequential steps, the book assists and supports researchers and food industry operators in planning a shelf life study that best suits their needs. Offering an integrated view of the present status of shelf life assessment, the book covers: Definitions, basic concepts, and regulatory aspects of food shelf life The shelf life assessment process, including preliminary steps, testing, modeling, and monitoring Methods for determining acceptability limits Critical indicators in shelf life assessment Real-time and accelerated shelf life testing Microbial indicators for shelf life prediction and determination Survival analysis methodologies and their role in modeling shelf life The effect of packaging materials properties in food shelf life assessment The book concludes with a series of case studies involving fresh-cut apple slices, fruit juices, frozen pasta, cheese breadsticks, coffee, frozen shrimp, and fruit-based noncarbonated soft drinks. Each case study begins with a brief presentation of the product and the problem most relevant to the product’s shelf life. The studies first define acceptability limits and identify the indicators of quality loss. Next, the book examines expiration time assessment by instrumental or sensory tools. Providing researchers and food industry operators with up-to-date data and procedures, this volume surveys the most critical factors and methods for obtaining accurate and reliable shelf life dating.

"Encompasses the core considerations about shelf life. Section 1 introduces shelf life, describes its relationship to food safety, and provides answers to the frequently asked questions around shelf life determination and testing which are a manager's chief concerns. Section 2 covers the science of the various ways in which food deteriorates and spoils, including the physical, chemical and microbiological changes. Section 3 looks at shelf life in practice, using case studies of different products to illustrate how shelf life may be determined in real life settings"--

The subject of shelf life of foods is not a new one. Increasing consumer interest in food safety, quality and date marking, competitjve pressures from retailers and extensive legislative changes, however, have combined to give the subject a new significance. The proper and correct determina tion of shelf life is of course fundamental to Good Manufacturing Practice (GMP) for the food and drink industry. Manufacturers who aim to produce safe, wholesome and attractive food products 'right the first time' and 'right every time' will already know the importance of proper shelf life evaluation. Incorrect shelf lives can potentially bring about dire legal, safety or financial consequences. This is not to belittle the difficulty of failing to meet consumer expectations consistently as a result of shelf lives that have been arrived at unreliably. A proper evaluation of shelf life must be grounded on sound scientific principles, supported by up-to-date techniques in food science and tech nology. This book, therefore, begins with five chapters reviewing the prin ciples of shelf life evaluation. These are followed by ten chapters on a number of selected food products. All the authors either have first hand experience on the practice of shelf life evaluation or are involved in research of the subject. Because of the diversity and complexity of food products now available, no attempt has been made to cover every product group, let alone every product conceivable.

The shelf-life of a product is critical in determining both its quality and profitability. This important collection reviews the key factors in determining shelf-life and how it can be measured. Part one examines the factors affecting shelf-life and spoilage, including individual chapters on the major types of food spoilage, the role of moisture and temperature, spoilage yeasts, the Maillard reaction and the factors underlying lipid oxidation. Part two addresses the best ways of measuring the shelf-life of foods, with chapters on modelling food spoilage, measuring and modelling glass transition, detecting spoilage yeasts, measuring lipid oxidation, the design and validation of shelf-life tests and the use of accelerated shelf-life tests. Understanding and measuring the shelf-life of food is an important reference for all those concerned with extending the shelf-life of food. Reviews the key factors in determining shelf-life and how they can be measured Examines the importance of the shelf-life of a product in determining its quality and profitability Brings together the leading international experts in the field

Preservation and Shelf Life Extension focuses on the basic principles of ultraviolet light technology as applied in low-UV transmittance treatments of food fluids and solid foods. It describes the features of UV light absorption in food fluids and available commercial systems, and provides case studies for UV treatment of fresh juices, dairy products, wines, and beer. The book also includes information on various continuous and pulsed UV sources and processing systems, as well as examples of specific treatments for fruits, vegetables, meat and poultry products. Addresses preservation and shelf-life extension of foods and food plant safety improvement Explores non-thermal and non-chemical alternatives for preservation and shelf-life extension of fluid foods, drinks and beverages, and for solid foods Written by an internationally recognized expert in ultraviolet light, high hydrostatic pressure processing, and microwave heating

The book covers the applications of some alternative approaches for prolonging food shelf life. the book describes the role of food safety objectives, natural compounds (such as oils and microbial enzymes), pressure and atmospheric techniques and alternative approaches (microwave, irradiation and mathematical microbial modeling) in food preservation. Implications of preservative approaches on food texture and sensorial quality are also discussed along with technology related hurdles commonly encountered in the field. the book should be very useful for food producers and microbiologists.
