<p>The study was undertaken to meet the following objectives:</p>
<ul>
<li>to collate and assess information in relation to the current and projected use of nanomaterials as food additives or food ingredients</li>
<li>to assess the potential hazards that might be associated with the nano-sized food additives or food ingredients</li>
<li>to assess the likely implications of the use of nano-sized food additives or food ingredients in terms of consumer safety and current regulatory controls in the UK</li>
<li>to identify any gaps in knowledge and regulations, and to provide guidance on the needs for future R&D, and any needs for supporting (new or adjusted) regulatory frameworks</li>
</ul>
<p>Background: The advent of nanotechnology, that involves manufacture and use of materials in the size range of up to 100 nanometres, has opened up a way for a multibillion dollar global industry in recent years.</p>
<p>The applications of nanotechnology in the food sector are emerging, but they are predicted to grow rapidly in the coming years. This is because food industry has always been looking out for new technologies to improve the nutritional value, shelf life, and traceability of food products, and to provide new tastes, flavours, textures etc. A number of new processes and materials derived from nanotechnology can provide answers to such needs. </p>
