ABSTRACT
Nanotechnology has tremendous scope in the packaging of dairy products to extend the storage quality and enhance safety. The application and functionalities of nanopackaging can lead to manipulation of permeation of moisture and gases and greater strength of the package as well as the possibility of introduction of nanoactive compounds through packaging that may potentially deliver various functional benefits to the consumer, such as extended shelf life, product traceability, incorporation of smart/intelligent systems for integration of remote geographic positioning parameters, and security during transportation. Other functional deliverables include specific nutrient delivery, controlled release of flavors into the product, auto-repair of any physical damages to the package, and discharge of selected beneficial additives to enhance the shelf life. Nanopackaging can also be applied to reinforce food safety by integrating a system to alert the consumers whether the packaged food is spoilt or contaminated. Nanotechnology can be integrated into packaging with the adoption and incorporation of specific nanoliposomes, nanoemulsion, nanofibers, nanoencapsulation, nanocoating, and nanosized ingredients. This technology can help the dairy and meat industry to gain a more competitive edge through enhanced shelf life and improved functionality and safety of market milk, dairy powders, meat cuts, and dairy and meat-based products.
