This Brief evaluates the consequences of protein modifications in cheeses, with special emphasis on mozzarella cheeses. It explains the influence of biogenic amines on food quality and safety. As certain biogenic amines display a toxic potential to humans, considerable research has been undertaken in recent years to evaluate their presence in fermented foods, such as cheeses. This Brief summarizes how the presence of amines is influenced by different factors such as cheese variety, seasoning and microflora. The authors compare typical profiles of different products, e.g. ripe vs. unripe cheeses, focusing also on the different types of mozzarella cheeses. The Brief also introduces several analytical methods and simulation techniques, which are being used to evaluate the evolutive profiles of different selected molecules, protein aggregation, or proteolysis.
Social Ecology of Infectious Diseases explores how human activities enable microbes to disseminate and evolve, thereby creating favorable conditions for the diverse manifestations of communicable diseases. Today, infectious and parasitic diseases cause about one-third of deaths and are the second leading cause of morbidity and mortality. The speed that changes in human behavior can produce epidemics is well illustrated by AIDS, but this is only one of numerous microbial threats whose severity and spread are determined by human behaviors. In this book, forty experts in the fields of infectious diseases, the life sciences and public health explore how demography, geography, migration, travel, environmental change, natural disaster, sexual behavior, drug use, food production and distribution, medical technology, training and preparedness, as well as governance, human conflict and social dislocation influence current and likely future epidemics. - Provides essential understanding of current and future epidemics - Presents a crossover perspective for disciplines in the medical and social sciences and public policy, including public health, infectious diseases, population science, epidemiology, microbiology, food safety, defense preparedness and humanitarian relief - Creates a new perspective on ecology based on the interaction of microbes and human activities
Flavour is key to the acceptance of cheese products among consumers and is therefore a critical issue for professionals in the dairy industry. However, the manufacture of cheeses that are consistently safe and flavourful often eludes scientists. Developments such as high throughput genome sequencing and metabolite analysis are having a significant impact on research, leading to the development of new tools to control and improve the flavour of cheese. With contributions from an international array of acclaimed authors, Improving the flavour of cheese, provides crucial reviews of recent research in the field.The book begins with a summary of cheese ripening and the compounds associated with cheese flavour. Part one discusses the metabolism of specific substrates to flavour compounds by microbes associated with milk and cheese. Part two reviews the influence of ingredients, processing and certain chemical and physical factors on cheese flavour. Part three addresses the measurement of cheese flavour. The book concludes with a selection of case studies on specific product types such as hard Italian, brined cheese, as well as low fat and soft-ripened cheeses.Improving the flavour of cheese provides a unique review of emerging techniques and ideas to control the flavour of cheese. This original book will be a standard reference for those concerned with the development and manufacture of cheese. - Discusses the wealth of research in the area of flavour development - Reviews the influence of ingredients, processing and certain chemical and physical factors on cheese flavour - Concludes with a selection of case studies on specific product types
Although the art of making cheese can be traced to prehistoric times, it has continued to evolve as modern civilization progressed. The advent of new technologies and instrumentation has brought exponential growth in the understanding of cheese components and their function. Even more recently, the evolution of cheesemaking has accelerated, driven by economic factors such as the establishment of the European Economic Community, the changing diet of developed countries, and the environmental and economic concerns associated with whey disposal. Molecular biology has revolutionized the development of starter and adjunct cultures as well as rennets, and genetics will make it possible to maintain ideal milk components for cheesemaking. The ability to accelerate traditional ripening procedures has altered the production of certain cheeses, and the emphasis on decreasing the intake of dietary fat, especially in the United States, has prompted the development of technology for producing low-fat cheeses with traditional texture and flavor. In assembling a distinguished group of participants for the symposium, "Chemistry of the Structure/Function Relationships in Cheese," we hoped to review the interplay of these trends and forecast the direction of future research. Contributors evaluated the current status of cheesemaking and highlighted the information that will be essential for new developments. They also focused the attention of agricultural and food chemists on the opportunities in cheese research and the potential contributions they might make to the future of cheese, a most valuable food product. We are indebted to Dr. Patrick Fox, Dr. Mark Johnson, Dr. Milos Kalab, Dr.
Describes the science of cheese making, from chemistry to biology, in a lively way that is readable for both the food scientist and the artisanal hobbyist.
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. Since 1999 when the first edition of this book was published, it has facilitated readers’ understanding of the methods, technology, and science involved in the manipulation of conventional and newer sophisticated food preservation methods. The Third Edition of the Handbook of Food Preservation provides a basic background in postharvest technology for foods of plant and animal origin, presenting preservation technology of minimally processed foods and hurdle technology or combined methods of preservation. Each chapter compiles the mode of food preservation, basic terminologies, and sequential steps of treatments, including types of equipment required. In addition, chapters present how preservation method affects the products, reaction kinetics and selected prediction models related to food stability, what conditions need be applied for best quality and safety, and applications of these preservation methods in different food products. This book emphasizes practical, cost-effective, and safe strategies for implementing preservation techniques for wide varieties of food products. Features: Includes extensive overview on the postharvest handling and treatments for foods of plants and animal origin Describes comprehensive preservation methods using chemicals and microbes, such as fermentation, antimicrobials, antioxidants, pH-lowering, and nitrite Explains comprehensive preservation by controlling of water, structure and atmosphere, such as water activity, glass transition, state diagram, drying, smoking, edible coating, encapsulation and controlled release Describes preservation methods using conventional heat and other forms of energy, such as microwave, ultrasound, ohmic heating, light, irradiation, pulsed electric field, high pressure, and magnetic field Revised, updated, and expanded with 18 new chapters, the Handbook of Food Preservation, Third Edition, remains the definitive resource on food preservation and is useful for practicing industrial and academic food scientists, technologists, and engineers.
Non-Bovine Milk and Milk Products presents a compiled and renewed vision of the knowledge existing as well as the emerging challenges on animal husbandry and non-cow milk production, technology, chemistry, microbiology, safety, nutrition, and health, including current policies and practices. Non-bovine milk products are an expanding means of addressing nutritional and sustainable food needs around the world. While many populations have integrated non-bovine products into their diets for centuries, as consumer demand and acceptance have grown, additional opportunities for non-bovine products are emerging. Understanding the proper chain of production will provide important insight into the successful growth of this sector. This book is a valuable resource for those involved in the non-cow milk sector, e.g. academia, research institutes, milk producers, dairy industry, trade associations, government, and policy makers. - Discusses important social, economic, and environmental aspects of the production and distribution of non-bovine milk and milk products - Provides insight into non-bovine milk from a broad range of relevant perspectives with contributions from leading researchers around the world - Focuses on current concerns including animal health and welfare, product safety, and production technologies - Serves as a valuable resource for those involved in the non-cow milk sector
