Indian Scientists develop Carbon-based Wrapper for preserving Fruits

Indian researchers led by Dr. P. S Vijayakumar from Institute of Nano Science and Technology, Mohali have developed a composite paper made of carbon (graphene oxide) loaded with preservatives that can be used as wrappers to help extend shelf life of fruits.
Unlike the present preservative dipping technology, where the preservatives are adsorbed by the fruit, causing chronic toxicity to the consumers; here preservatives the wrapper releases the preservative only when needed. Conventional preservation relies on coating the preservative with the resin, wax, or edible polymer, which may cause chronic health problems.
The wrapper can be reused, which is not possible with the present technology.
