Globalised distribution and supply chains make itimperative that food should survive the transit between producerand consumer as a perishable commodity, food carries a highrisk of spoilage. As such, a realistic, workable and reproducibleshelf life has to be determined every time a new food product isdeveloped and marketed; shelf life determination of food has becomean integral part of food safety, quality assurance, productdevelopment, marketing, and consumer behaviour. Dominic Man s Shelf Life, now in a revised and updatedsecond edition, encompasses the core considerations about shelflife. Section 1 introduces shelf life, describes its relationshipto food safety, and provides answers to the frequently askedquestions around shelf life determination and testing which are amanager s chief concerns. Section 2 covers the science of thevarious ways in which food deteriorates and spoils, including thephysical, chemical and microbiological changes. Section 3 looks atshelf life in practice, using case studies of different products toillustrate how shelf life may be determined in real life settings.This book will be invaluable to both practitioners and students inneed of a succinct and comprehensive overview of shelf lifeconcerns and topics.
