The project involves the University of Guelph in Canada, Tamil Nadu Agriculture University (TNAU) in India, the Industrial Technology Institute (ITI) in Sri Lanka, and MYRADA, a nongovernmental organisation based in southern India. The project follows studies at Tamil Nadu Agriculture University (TNAU) showning that a nano-film that emits Hexanal, which is found in trace amounts in plants such as beans and cucumbers, as a vapour that can extend the shelf-life of vegetables by up to 21 days without an...
