Food Contact Polymeric Materials

Polymeric materials have revolutionised the way we package store and even cook our food. We now buy soft and alcoholic drinks in transparent, lightc099 plastic bottles, and precooked meals in plastic trays which we reheat in a microwave or conventional oven. This state-of-the-art review draws together the legal framework within which the industry must work, with the technological advances being made both in materials performance and the analysis of migrating monomers and additives. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

The purpose of this book will be to demonstrate 1) the newly developed method of using reactive functionalized materials in agriculture to solve the economic and public health problems associated with using conventional agrochemicals; and 2) new technology aimed at achieving the greening of chemistry to meet appropriate environmental standards in both agriculture and industrial foodstuffs production. More specifically, the book will accomplish this goal by addressing 3 key issues in the field: 1) the production of reactive functionalized materials with enhanced properties that offer a major opportunity to overcome the disadvantages of using traditional materials; 2) the applications of functionalized materials in agriculture for the purpose of solving the economic and the environmental pollution problems associated with the uses of conventional agrochemicals; and 3) the contribution of polymers in solving problems associated with conventional procedures of food growth and processing, including those used in the dairy industry, sugar and fruit juices, beer and wine production, nutritive and nonnutritive food additives, and in food protection.

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.

Recent developments in multifunctional and nanoreinforced polymers have provided the opportunity to produce high barrier, active and intelligent food packaging which can help ensure, or even enhance, the quality and safety of packaged foods. Multifunctional and nanoreinforced polymers for food packaging provides a comprehensive review of novel polymers and polymer nanocomposites for use in food packaging. After an introductory chapter, Part one discusses nanofillers for plastics in food packaging. Chapters explore the use of passive and active nanoclays and hidrotalcites, cellulose nanofillers and electrospun nanofibers and nanocapsules. Part two investigates high barrier plastics for food packaging. Chapters assess the transport and high barrier properties of food packaging polymers such as ethylene-norbornene copolymers and advanced single-site polyolefins, nylon-MXD6 resins and ethylene-vinyl alcohol copolymers before going on to explore recent advances in various plastic packaging technologies such as modified atmosphere packaging (MAP), nanoscale inorganic coatings and functional barriers against migration. Part three reviews active and bioactive plastics in food packaging. Chapters investigate silver-based antimicrobial polymers, the incorporation of antimicrobial/antioxidant natural extracts into polymeric films, and biaoctive food packaging strategies. Part four examines nanotechnology in sustainable plastics with chapters examining the food packaging applications of polylactic acid (PLA) nanocomposites, polyhydroxyalkanoates (PHAs), starch-based polymers, chitosan and carragenan polysaccharides and protein-based resins for packaging gluten (WG)-based materials. The final chapter presents the safety and regulatory aspects of plastics as food packaging materials. With its distinguished editor and international team of expert contributors Multifunctional and nanoreinforced polymers for food packaging proves a valuable resource for researchers in packaging in the food industry and polymer scientists interested in multifunctional and nanoreinforced materials.

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.

Now, more than ever, foods come packaged in containers designed for direct cooking or heating, which often causes the movement of substances - indirect additives - into foods. Because of their unique characteristics, plastics or polymeric materials (PM) have become the most important packaging material for food products. The safety assessment of plastics intended for use in contact with foodstuffs or drinking water continues to present a serious challenge. Indirect Food Additives and Polymers: Migration and Toxicology studies the potential hazards of indirect additives for human health and develops recommendations for their safe manufacture and use. It contains an impressive review of basic regulatory, toxicological, and other scientific information necessary to identify, characterize, measure, and predict the hazards of nearly 2,000 plastic-like materials employed in packaging.
