Summary : Predicting the growth and behaviour of microorganisms in food has long been an aim in food microbiology research. In recent years, microbial models have evolved to become more exact and the discipline of quantitative microbial ecology has gained increasing importance for food safety management, particularly as minimal processing techniques have become more widely used. These processing methods operate closer to microbial death, survival and growth boundaries and therefore require even more precise models. Written by a team of leading experts in the field, Modelling microorganims in food assesses the latest developments and provides an outlook for the future of microbial modelling. Part one discusses general issues involved in building models of microbial growth and inactivation in foods, with chapters on the historical background of the field, experimental design, data processing and model fitting, the problem of uncertainty and variability in models and modelling lag-time. Further chapters review the use of quantitative microbiology tools in predictive microbiology and the use of predictive microbiology in risk assessment. The second part of the book focuses on new approaches in specific areas of microbial modelling, with chapters discussing the implications of microbial variability in predictive modelling and the importance of taking into account microbial interactions in foods. Predicting microbial inactivation under high pressure and the use of mechanistic models are also covered. The final chapters outline the possibility of incorporating systems biology approaches into food microbiology. Modelling microorganisms in food is a standard reference for all those in the field of food microbiology.

Summary : Predictive microbiology is a recent area within food microbiology, which studies the responses of microorganisms in foods to environmental factors (e.g., temperature, pH) through mathematical functions. These functions enable scientists to predict the behavior of pathogens and spoilage microorganisms under different combinations of factors. The main goal of predictive models in food science is to assure both food safety and food quality. Predictive models in foods have developed significantly in the last 20 years due to the emergence of powerful computational resources and sophisticated statistical packages. This book presents the concepts, models, most significant advances, and future trends in predictive microbiology. It will discuss the history and basic concepts of predictive microbiology. The most frequently used models will be explained, and the most significant software and databases (e.g., Combase, Sym’Previus) will be reviewed. Quantitative Risk Assessment, which uses predictive modeling to account for the transmission of foodborne pathogens across the food chain, will also be covered. ​

Summary : With growing consumer demand for ready-to-eat (RTE) foods that are wholesome and require less handling and preparation, the production of RTE foods has increased and their variety has expanded considerably, spanning from bagged spinach to pre-packaged school lunches. But since RTE foods are normally consumed directly without cooking — a step that kills pathogenic microorganisms that may be present in the food products — concerns exist with regard to their safety. Several severe and high-profile outbreaks of food-borne illness linked to the consumption of RTE foods have prompted the USDA and FDA to issue stringent rules and regulations governing the manufacturing of RTE foods. Ready-to-Eat Foods: Microbial Concerns and Control Measures comprehensively reviews individual common RTE food and their specific safety-related aspects. This text explores the extensive research conducted by the food industry, academia, and research institutes that examines the potential health risk of contaminated RTE foods, investigates the growth behavior of common contaminating foodborne pathogens, and develops intervention technologies and control measures. The book supplies an overview of food safety of RTE foods and various categories into which they fall. It also addresses the microorganisms of concern, the effect of processing on the survival of pathogenic and spoilage microorganisms, food safety, practical control measures, and intervention strategies. Ready-to-Eat Foods: Microbial Concerns and Control Measures is a critical reference for scientists and professionals working on the forefront of food safety and RTE food manufacturing.
