Recently, a research team from Nanyang Technological University in Singapore and Harvard University School of Public Health developed a smart food packaging material

This kind of food packaging is made of a substance called zein, starch and other natural biopolymers, and infused with a mixture of natural antibacterial compounds

In laboratory experiments, when exposed to increased humidity or enzymes produced by harmful bacteria, the fibers in the packaging will release traces of natural antibacterial compounds, killing common dangerous bacteria that contaminate food (whether the bacteria are on the packaging surface or the food itself On the surface), such as Escherichia coli and Listeria

The food packaging may be used for a variety of products, including ready-to-eat food, raw meat, fruits and vegetables

In this study, the researchers used natural compounds including biopolymers, non-toxic solvents, and natural antibiotics, and developed a scalable system to synthesize smart antibacterial materials
