Nanotechnology: Giving a new dimension to Food Industry INTRODUCTION: A derivative of chemistry, engineering, and physics, and micro fabrication techniques, nanotechnology involves manipulating matter at the nanoscale level. It is responsible for determining not only that biological and nonbiological structures measuring less than 100 nm exist but also that they have unique and novel functional applications. In fact, the National Nanotechnology Initiative (NNI, 2006) defines nanotechnology as ?the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications.? Because applications with structural features on the nanoscale level have physical, chemical, and biological properties that are substantially different from their macroscopic counterparts, nanotechnology can be beneficial on various levels. Research in biology, chemistry, engineering, and physics drives the development and exploration of the nanotechnology field. Consequently, certain industries such as microelectronics, ae experian dispute rospace, and pharmaceuticals have already begun manufacturing commercial products of nanoscale size. Even though the food industry is just beginning to explore its applications, nanotechnology exhibits great potential. Food undergoes a variety of postharvest and processing-induced modifications that affect its biological and biochemical makeup, so nanotechnology developments in the fields of biology and biochemistry could eventually also influence the food industry. Ideally, systems with structural features in the nanometer length range could affect aspects from food safety to molecular synthesis. Potential Food Applications: All organisms represent a consolidation of various nanoscale-size objects. Atoms and molecules combine to form dynamic structures and systems that are the building blocks of every organism?s existence. For humans, cell membranes, hormones, and DNA are examples of vital structures that measure in the nanometer range. In fact, every living organism on earth exists because of the presence and interaction of various nanostructures.
