NUS researchers develop new food packaging material that could double shelf-life of food products

Assoc Prof Thian Eng San and PhD candidate Ms Tan Yi Min from the Dept of Mechanical Engineering at the NUS Faculty of Engineering have developed an environmentally-friendly food packaging material that is free from chemical additives, by fortifying natural chitosan-based composite film with grapefruit seed extract. The material can slow down fungal and bacterial growth, doubling the shelf-life of perishable food, such as bread.
