This document discusses potential applications of nanotechnology in the dairy industry. It begins by providing background on the origins of nanotechnology. It then discusses how nanotechnology can be used to fortify milk with nutrients through nanoencapsulation and the use of nanomaterials. Nanoparticles can also be used to improve food safety by acting as antimicrobial agents and enabling pathogen detection. Additional applications include using nanotechnology to develop low-fat and functional dairy products, as well as nanocoatings to improve packaging and extend shelf life. Overall, the document outlines how nanotechnology offers opportunities to enhance the nutritional profile, safety, and functionality of dairy products.
