DOWNLOAD EBOOKApproximately 30 percent of the edible food produced in the United States is wasted and a significant portion of this waste occurs at the consumer level. Despite food's essential role as a source of nutrients and energy and its emotional and cultural importance, U.S. consumers waste an estimated average of 1 pound of food per person per day at home and in places where they buy and consume food away from home. Many factors contribute to this wasteâ€"consumers behaviors are shaped not only by individual and interpersonal factors but also by influences within the food system, such as policies, food marketing and the media. Some food waste is unavoidable, and there is substantial variation in how food waste and its impacts are defined and measured. But there is no doubt that the consequences of food waste are severe: the wasting of food is costly to consumers, depletes natural resources, and degrades the environment. In addition, at a time when the COVID-19 pandemic has severely strained the U.S. economy and sharply increased food insecurity, it is predicted that food waste will worsen in the short term because of both supply chain disruptions and the closures of food businesses that affect the way people eat and the types of food they can afford. A National Strategy to Reduce Food Waste at the Consumer Level identifies strategies for changing consumer behavior, considering interactions and feedbacks within the food system. It explores the reasons food is wasted in the United States, including the characteristics of the complex systems through which food is produced, marketed, and sold, as well as the many other interconnected influences on consumers' conscious and unconscious choices about purchasing, preparing, consuming, storing, and discarding food. This report presents a strategy for addressing the challenge of reducing food waste at the consumer level from a holistic, systems perspective.

DOWNLOAD EBOOKThis comprehensive reference combines the technological know-how from five centuries of industrial-scale brewing to meet the needs of a global economy. The editor and authors draw on the expertise gained in the world's most competitive beer market (Germany), where many of the current technologies were first introduced. Following a look at the history of beer brewing, the book goes on to discuss raw materials, fermentation, maturation and storage, filtration and stabilization, special production methods and beermix beverages. Further chapters investigate the properties and quality of beer, flavor stability, analysis and quality control, microbiology and certification, as well as physiology and toxicology. Such modern aspects as automation, energy and environmental protection are also considered. Regional processes and specialties are addressed throughout the entire book, making this a truly global resource on brewing.
