2、a consideration of opportunities for developing countries Emma L. Bradley, Laurence Castle and Qasim Chaudhry This concise review describes the science and technology developments made towards applications of nanomaterials in food packaging materials. The technical benefits of actual and near- marke
3、t applications are described. The uncertainties over risks that some of these novel materials may pose to consumer safety and environmental safety are outlined along with the corresponding regulatory barrier that this poses to innovation and new product development. Finally, some opportunities and a
4、pproaches are proposed for developing countries to gain the expected benefits of the newly emerging nanotechnologies. This could involve taking the new science and technology, developed already for retail packaging, and adapting it for more local needs. Introduction Nearly all of the food and drink
5、that we buy and then consume is packaged in some way. The main functions of food packaging is to protect and preserve the food, to maintain its quality and safety, and to reduce food waste. There can be no doubt that modern food packaging materials and technologies fulfil these functions and packagi
6、ng plays a key role in help ing to provide a safe and nutritious food supply. However, the food and beverage industry is always seeking new technologies to further improve the quality, shelf life, safety and traceability of their products. The advent of nanotechnology, that involves manufacture and use of materials in the size range of up to about 100 nm in one or more dimensions, has opened up new opportunities for the development of new materials with improved properties for use as food con
