FrogHeart at the 2012 S.NET conference, part 2: Canada, nano, and the mango

I was delighted to learn more about the nanotechnology collaboration between Canada, India, and Sri Lanka (mentioned in my India, Sri Lanka, and Canada team up for nanotechnology-enabled food packaging posting of June 21, 2012) at the S.Net 2012 conference.

Rumana Bukht and Sally Randles from the University of Manchester’s Business School titled their presentation, Intervention of the State on Responsible Development of Nanotechnology in Canada.

Before discussing the presentation, here’s a summary of the project from my June 21, 2012 posting,

From the June 20, 2012 University of Guelph news release,

University of Guelph scientists led by Prof. Jayasankar Subramanian will work with South Asian colleagues to develop innovative packaging using state-of-the-art nanotechnology to reduce post-harvest losses in mangoes, a vital fruit crop in South Asia.

The $2.3 million project, announced today by Canada’s International Development Research Centre (IDRC) and the Canadian International Development Agency (CIDA), will improve livelihoods for nearly one-third of the populations of India and Sri Lanka, mostly small-scale farmers.

The Guelph scientists will work with researchers from the Tamil Nadu Agricultural University in India and Sri Lanka’s Industrial Technology Institute.

“Invented in part at U of G, this new packaging system should reduce post-harvest losses in fruits in India and Sri Lanka, where optimal storage conditions are not readily available.”

Mangoes are the second largest fruit crop in India and third in Sri Lanka. Farmers lose 35 to 40 per cent of their crops ─ worth $800 million a year ─ because of poor storage.

The researchers will combine patented technologies to develop special fruit cartons, dividers and wraps lined with nanoparticles from coconut husks and banana plants. Using these farm waste products will help provide income for small-scale entrepreneurs, particularly women.

During her talk, Rumana mentioned hexanal as an important ingredient in this new packaging. While my notes don’t provide much information about this ingredient, I did find this great April 26, 2012 article by Arun P Mathew for the Times of India, which provides more technical detail,

K S Subramanian, head of the department of Nano Science and Technology, who is involved in the project said that the University of Guelph, Canada discovered that hexanal, a chemical extracted from plants could successfully enhance the shelf-life and quality of fruits and vegetables. A researcher at TNAU [Tamil Nadu Agricultural University] has come [up] with a nano-film, he said.

“A combination of these two technologies could help develop a nano film with hexanal, which will improve the longevity of these fruits. Through this technology, around 30 percent of the losses could be avoided. This will improve the export of fruits and vegetables and increase the sales of fruits making farming more economically viable,” he said. Subramanian said that they would first be applied on mangoes and later on other fruits, based on its success.

He said that this will be an eco-friendly product. “Hexanal has been approved by United States based, FDA ( Food and Drug Administration). …

Rumana noted there will be safety testing of this hexanal-based nano-film and the testing will take place in India (not Canada) because India has better safety equipment and personnel with the appropriate skill sets. Canada will contribute the safety protocols. If the mango project is successful, researchers are considering plums and peaches for future projects.

I did want to get more  information about this collaboration and about the Canadian nano scene. As I have noted many times, getting information is difficult and I gather Rumana experienced some of the same difficulties. At least, I’m inferring difficulty from the fact that she refused, due to confidentiality agreements, to tell me which Canadian government officials she’d spoken with although she did identify departments (Health Canada and Industry Canada). Given all the secrecy you’d think something nefarious was happening instead of an attempt to minimize food wastage.

India, Sri Lanka, and Canada team up for nanotechnology-enabled food packaging

Canada’s University of Guelph keeps coming up on my radar these days. The latest news concerns a nanotechnology-enabled food packaging technology. From the June 20, 2012 University of Guelph news release,

University of Guelph scientists led by Prof. Jayasankar Subramanian will work with South Asian colleagues to develop innovative packaging using state-of-the-art nanotechnology to reduce post-harvest losses in mangoes, a vital fruit crop in South Asia.

The $2.3 million project, announced today by Canada’s International Development Research Centre (IDRC) and the Canadian International Development Agency (CIDA), will improve livelihoods for nearly one-third of the populations of India and Sri Lanka, mostly small-scale farmers.

The Guelph scientists will work with researchers from the Tamil Nadu Agricultural University in India and Sri Lanka’s Industrial Technology Institute.

“We welcome the opportunity to work with leading scientists and institutes in Asia to raise the income of poor farmers and make food more nutritious and secure,” said Subramanian, a professor in Guelph’s Department of Plant Agriculture.

“Invented in part at U of G, this new packaging system should reduce post-harvest losses in fruits in India and Sri Lanka, where optimal storage conditions are not readily available.”

Mangoes are the second largest fruit crop in India and third in Sri Lanka. Farmers lose 35 to 40 per cent of their crops ─ worth $800 million a year ─ because of poor storage.

The researchers will combine patented technologies to develop special fruit cartons, dividers and wraps lined with nanoparticles from coconut husks and banana plants. Using these farm waste products will help provide income for small-scale entrepreneurs, particularly women.

I hope to hear more about this project as it progresses and hopefully next time, there’ll be a few more technical details. The mention of coconut husks and banana plants makes me wonder if they are talking about nanocellulose in some form or other.

For anyone who’s interested in the international aid aspects (from the news release),

The project is among six new initiatives funded by IDRC and CIDA under the Canadian International Food Security Research Fund (CIFSRF). The five-year, $62-million project links researchers in Canada and developing countries to address hunger and food insecurity in the developing world.

I last wrote about Sri Lanka and its nanotechnology efforts in my June 4, 2012 posting and I have mentioned India’s nanotechnology efforts several times but perhaps the most relevant, as per this item was in my April 4, 2012 posting.

ETA Oct. 31,2012: Minor grammatical changes were made in the final sentence. ‘Time’ was changed to ‘times’ and I removed the words ‘recent mention’ as they made no sense in the sentence.
