What is Nanotechnologythe study of the controlling of matter on anatomic and molecular scale. Generallynanotechnology deals with structuressized between 1 to 100 nanometer in atleast one dimension, and involvesdeveloping or modifying materials ordevices within that size.

Nanotechnologyis already making today’s products:• Lighter• Stronger• Faster• Smaller• More Durable

Nano for Consumer GoodsNanotechnology is already impacting the field ofconsumer goods, providing products with novelfunctions ranging from easy-to-clean to scratchresistant.Already in use are different nanoparticleimproved products. Especially in the field ofcosmetics, such novel products have a promisingpotential.

FoodsComplex set of engineering and scientific challenges in the food andbioprocessing industry for manufacturing high quality and safe foodthrough efficient and sustainable means can be solved throughnanotechnology. Bacteria identification and food quality monitoringusing biosensors; intelligent, active, and smart food packagingsystems; nanoencapsulation of bioactive food compounds are fewexamples of emerging applications of nanotechnology for the foodindustry.[10] Nanotechnology can be applied in the production,processing, safety and packaging of food. A nanocomposite coatingprocess could improve food packaging by placing anti-microbial agentsdirectly on the surface of the coated film. Nanocomposites couldincrease or decrease gas permeability of different fillers as is neededfor different products. They can also improve the mechanical and heatresistanceproperties and lower the oxygen transmission rate.Research is being performed to apply nanotechnology to the detectionof chemical and biological substances for sensanges in foods.

Nano-FoodsNew foods are among the nanotechnology-created consumer productscoming onto the market at the rate of 3 to 4 per week, according to theProject on Emerging Nanotechnologies (PEN), based on an inventory ithas drawn up of 609 known or claimed nano-products.On PEN's list are three foods—a brand of canola cooking oil calledCanola Active Oil, a tea called Nanotea and a chocolate diet shakecalled Nanoceuticals Slim Shake Chocolate.According to company information posted on PEN's Web site, thecanola oil, by Shemen Industries of Israel, contains an additive called"nanodrops" designed to carry vitamins, minerals and phytochemicalsthrough the digestive system and urea.The shake, according to U.S. manufacturer RBC Life Sciences Inc.,uses cocoa infused "NanoClusters" to enhance the taste and healthbenefits of cocoa without the need for extra sugar.

AgricultureApplications of nanotechnology have the potential to change the entireagriculture sector and food industry chain from production toconservation, processing, packaging, transportation, and even wastetreatment. NanoScience concepts and nanotechnology applicationshave the potential to redesign the production cycle, restructure theprocessing and conservation processes and redefine the food habits ofthe people.Major challenges related to agriculture like low productivity in cultivableareas, large uncultivable areas, shrinkage of cultivable lands, wastageof inputs like water, fertilizers, pesticides, wastage of products and ofcourse Food security for growing numbers can be addressed throughvarious applications of nanotechnology.
