Indirect Food Additives and Polymers by Victor O. Sheftel Pdf

More foods are now packaged in containers designed for direct cooking or heating, which encourages movement of substances into the foods. Indirect Food Additives and Polymers: Migration and Toxicology is an impressive review of basic regulatory, toxicological, and other scientific information necessary to identify, characterize, measure, and predict the hazards of nearly 2,000 of the plastic-like materials employed in packaging and identified by the FDA as indirect food additives. It presents the data underlying federal regulations, previously unavailable in one volume, and is a convenient resource for anyone working in the large number of related disciplines.

Functional Polymers in Food Science by Giuseppe Cirillo,Umile Gianfranco Spizzirri,Francesca Iemma Pdf

Polymers are an important part in everyday life; products made from polymers range from sophisticated articles, such as biomaterials, to aerospace materials. One of the reasons for the great popularity exhibited by polymers is their ease of processing. Polymer properties can be tailored to meet specific needs by varying the "atomic composition" of the repeat structure, by varying molecular weight and by the incorporation (via covalent and non-covalent interactions) of an enormous range of compounds to impart specific activities. In food science, the use of polymeric materials is widely explored, from both an engineering and a nutraceutical point of view. Regarding the engineering application, researchers have discovered the most suitable materials for intelligent packaging which preserves the food quality and prolongs the shelf-life of the products. Furthermore, in agriculture, specific functionalized polymers are used to increase the efficiency of treatments and reduce the environmental pollution. In the nutraceutical field, because consumers are increasingly conscious of the relationship between diet and health, the consumption of high quality foods has been growing continuously. Different compounds (e.g. high quality proteins, lipids and polysaccharides) are well known to contribute to the enhancement of human health by different mechanisms, reducing the risk of cardiovascular disease, coronary disease, and hypertension. This first volume, of this two volume book, concerns the application of polymers in food packaging.

The Sustainable Chef by Stefan Gössling,C. Michael Hall Pdf

This book provides the first systematic and accessible text for students of hospitality and the culinary arts that directly addresses how more sustainable restaurants and commercial food services can be achieved. Food systems receive growing attention because they link various sustainability dimensions. Restaurants are at the heart of these developments, and their decisions to purchase regional foods, or to prepare menus that are healthier and less environmentally problematic, have great influence on food production processes. This book is systematically designed around understanding the inputs and outputs of the commercial kitchen as well as what happens in the restaurant from the perspective of operators, staff and the consumer. The book considers different management approaches and further looks at the role of restaurants, chefs and staff in the wider community and the positive contributions that commercial kitchens can make to promoting sustainable food ways. Case studies from all over the world illustrate the tools and techniques helping to meet environmental and economic bottom lines. This will be essential reading for all students of hospitality and the culinary arts.

Weathering of Plastics by George Wypych Pdf

In spite of extensive efforts, material weathering testing still requires improvement. This book presents findings and opinions of experts in material degradation testing. The aim is to improve testing methods and procedures. Materials are presented to show that photochemical degradation rate depends on a combination of environmental factors such as UV radiation, temperature, humidity, rain, stress, and concentration of reactive pollutants. The potential effect of each parameter of degradation on data gathered is discussed based on known results from a long experience in testing. This book contains data obtained in laboratories of the largest manufacturers of UV stabilizers and chemical companies that manufacture durable materials. The book gives details of testing procedures and choice of parameters of exposure which are crucial for obtaining laboratory results correlating with environmental performance of materials. In addition to exposure conditions, the book contains many suggestions on sample preparation and post-exposure testing. The effective use of these methods shortens testing time of materials and determines acceleration rate of testing. The book also gives examples of complete, well-designed weathering experiments which may be used as patterns for selection of parameters and techniques for new studies. The areas of research that still require more attention in future studies are clearly indicated.
