This is a very good website called The Guardian. It explains that over 1600 products have nanoparticles. One type of nanotechnology is Microbe-killing silver which kills bacteria and odours. There are potential risks of nanotechnology like if when the customer sweats the nanotech might go on their skin. Through research, it is proven that people care more about the pros of nanotech than the cons.
This website names the benefits of nanotechnology in food. They explain it in 4 major categories: Agriculture, Food Processing, Food Packaging, and Supplements. In the category of agriculture, the website said that nanotech would help with delivery of products and nanocapsules can be used as pesticides and fertilizers. Under the category of food processing, it explains that nanocapsules can be used to add flavour more easily. Under the category of food packaging, they explained that with nanoparticles they could make packaging stronger and they could also use nanosensors to check the temperature and moisture inside a package. In the last category of supplements, they explained that nanocochleates can be used to deliver more nutrients and good things and the taste will not be changed.
