Nanomaterials research is continually developing, allowing for the creation of novel materials and, more importantly, the discovery of new applications. Biomedical applications, engineering sciences, and food technologies all make extensive use of nanotechnology. The use of nanocompounds is essential for protecting, preserving, and extending the shelf life of food. The quality of food is directly impacted by alterations in lifestyle, the usage of pesticides, and biological and/or chemical pollutants. Metallic nanoparticles (MNPs) are helpful for creating goods with antibacterial properties and with the potential to lengthen food and food product shelf life. It is simple to combine biopolymers/polymers with various MNPs, that allows the merging of organic chemicals with metallic nanocompounds, which act as a transporter for a range of materials.. However, before using nanoparticles in food packaging, risk assessment is required. As quality and safety are desired in food technology, we want to address how MNPs can be employed for food preservation in this review.
