Application of nanotechnology in food packaging: Pros and Cons

Nanotechnology used in the synthesis of nanoparticles has attracted great interest in the field of food packaging. It promises the development of food packages with upgraded properties that helps in prolonging the shelf life of food products. This review presents the most commonly used nanoparticles in food packaging, the significant changes they cause in the properties of packaging material, and the commercially available nano-based packaging materials. Nanoparticles are used in the development of improved packaging, active packaging, and intelligent packaging which helps in the maintenance of food quality and traceability during the supply chain. Nanoparticles possess antimicrobial activity, oxygen scavenging ability, UV impermeability, and various other properties that make them valuable for their application in the preparation of nanocomposites. The large surface area to volume ratio sometimes becomes the reason for nanoparticle toxicity so it is important to study their migration and interaction with polymer matrix while developing packaging materials.

Automated summary

The application of nanotechnology in food packaging has received significant attention. By using nanoparticles, food packages with upgraded properties can be developed to prolong the shelf life of food products. Nanoparticles are not only used to improve the properties of packaging material, but also for active packaging and intelligent packaging, which help in maintaining food quality and traceability.
