The largest manufacturing sector in the world among all industrial divisions, the food industry uses molecules as starting material, modifying those molecules, and building interactions in order to get the desired properties. In this regard, nanotechnology is poised to create better meal, from how food is grown to how it is packaged. 
Researchers and manufacturers have already identified the potential applications of nanotechnology in virtually every subdivision of the food industry, the most important of which are encapsulation of flavor and odor enhancers; food textural and quality improvement; pathogen, gas, and abuse sensors; anticounterfeiting devices; UV-protection; and impermeable polymer films; and nutrient supplements. The most common nanomaterials in the field are silver, gold, titanium dioxide, and silicon dioxide nanoparticles.

Nano-based products of the agriculture industry are classified into the following subdivisions:
1. Beverages
2. Chocolate
3. Meal
4. Packaging
5. Sports Nutrition
6. Supplements
7. Tobacco
