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 best-selling first edition of this contributed book established itself as a highly practical and authoritative source of information on shelf-life evaluation. Every food manufacturer is concerned about shelf life, as are the major retailers and ingredient suppliers. Increasing consumer interest in food safety, quality and date marking, competitive pressures from retailers and extensive legislative changes have combined to give this subject new significance. A proper evaluation of shelf life must be grounded on sound scientific prinicles, supported by up-to-date techniques. This book begins with six chapters reviewing the principles of shelf-life evaluation, followed by ten chapters on a number of selected food products such as chilled yogurt and other dairy desserts, seafood, and meat. The latest edition has been expanded to include new chapters on HACCP, preservation technology and shelf life, and minimally processed, ready-to-eat ambient-stable meat products. Sufficient information on the principles and practice of shelf life evaluation has been included for the beginner as well as for those who are more experienced in this area.

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

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.

Demand for minimally processed foods has resulted in the development of innovative, non-thermal food preservation methods, such as high-pressure sonication, ozone, and UV treatment. This book presents a summary of these novel food processing techniques. It also covers new methods used to monitor microbial activity, including spectroscopic methods (FT-IR and Raman), molecular and electronic noses, and DNA-based methods.

Principles and Practices for the Safe Processing of Foods presents information on the design, construction, and sanitary maintenance of food processing plants. This book also provides guidelines for establishing and implementing the Hazard Analysis Critical Control Points (HACCP) System and for training personnel in hygienic practices. This text is divided into 13 chapters and begins with the assessment of corporate policies concerning the controlled production of clean, wholesome foods in a sanitary manner. The next chapters deal with some of the requirements for safe food processing, including the establishment and implementation of HACCP rules, building status, sanitation, and personnel. A chapter briefly covers the structure of some microorganisms that affect safe food, such as viruses, bacteria, and fungi. This topic is followed by discussions of the biological factors underlying food safety, preservation, and stability; the principles and application of microbiological control methods; pathogenicity and pathogen profiles; and enzymes and their importance in food spoilage. The last chapters examine the aspects of microbiological safety in food preservation technologies and the criteria for ingredients and finished products. This book will prove useful to food manufacturers, policy makers, and public health workers.
