I’ve been wondering what happened since I posted about this ‘mango’ project some years ago (my June 21, 2012 posting and my Nov. 1, 2012 posting) so, it’s nice to get an update from this Fresh Fruit Portal Feb. 4, 2015 posting,
Developed by Canadian, Indian and Sri Lankan researchers in a collaborative project funded by the International Development Research Centre (IDRC), the nanotech mango boxes are said to improve the fruit’s resilience and therefore boost quality over long shipping distances.
The project – which also includes the Tamil Nadu Agricultural University, India and the Industrial Technical Institute, Sri Lanka – has tested the use of the bio-compound hexanal, an artificially synthesized version of a natural substance produced by injured plants to reduce post-harvest losses.
The nanotech boxes could be particularly significant for India as a world leader in mango production, as well as Sri Lanka where approximately 90,000 metric tons (MT) are produced annually.
The IDRC report says although South Asian fruit production is globally competitive, the region only meets around half of its demand due to poor processing and preservation facilities. Waste can be as high as 35% and amounts to billions of dollars in annual losses.
Historically, the Indian mango sector has suffered severe post-harvest loses due to the lack of cold chain supply infrastructure across the country, and developing a smart packing system like nanotech boxes could therefore be one way to address such challenges.
“Special boxes have been designed to reduce losses during transport. The boxes are sturdy, and can be stacked without risking damage to the fruit, and this alone can reduce post-harvest losses by 10-15%,” the IDRC report continues.
“In order to further improve the storage life of fruits during transport, the project has made a pioneering attempt to develop ‘nano-matrices’ using banana fibers to regulate the release of hexanal.
Canada’s International Development Research Centre (IDRC) and Foreign Affairs, Trade and Development Canada (DFATD) today announced three new projects to be supported under the Canadian International Food Security Research Fund (CIFSRF). The projects will help prevent livestock diseases and post-harvest fruit losses that affect millions of farmers around the world, and build on the successful research carried out during CIFSRF’s first phase.

- Researchers from the University of Guelph, Canada, Tamil Nadu Agricultural University, India, and the Industrial Technical Institute, Sri Lanka, have shown that a natural compound known as hexanal delays the ripening of mangos. Using nanotechnology, the team will continue to develop hexanal-impregnated packaging and biowax coatings to improve the fruit’s resilience during handling and shipping for use in Asia, Africa, and the Caribbean. It will also expand its research to include other fruit and look at ways to commercialize the technologies.
New funding will allow the research teams to further develop the new technologies and involve partners who can bring them to market to reach greater numbers of small-holder farmers.
It seems this new round of funding will help bring these nanotechnology-enabled products to market.
