Increased food security with hexanal for younger looking, fresher tasting fruits and vegetables

Also known as an anti-aging agent for your fruit and vegetables, hexanal is an environmentally friendly chemical, which is found naturally. Research has led to a synthesized nanotechnology-enabled product now being commercialized. I’ve been following the story off and on since 2012 (see my ‘India, Sri Lanka, and Canada team up for nanotechnology-enabled food packaging‘ posting). I last wrote about the project in a December 29, 2015 posting.

For some reason, hexanal hit the news hard in 2019 having been preceded by some interest in 2018. What follows is an update and a timeline of sorts.

January 2019: More funding

A January 24,2019 essay (also published on the University of Guelph website on January 29, 2019) by Jayasankar Subramanian and Elizabeth Finnis, both are lead researchers on the the project and professors at the University of Guelph (Canada), provides an overview and an update of the hexanal project (Note: Links have been removed) ,

Fruits like mangoes, bananas, papayas and limes are shipped long distances before they get to your table. Many fruits are delicate, and there may be a long period of time that elapses between when the fruit is picked and its arrival in grocery stores and other markets. They’re often picked before they’re truly ripe in order to increase their shelf life.

Even so, globally, up to 40 per cent of all picked fruit can be lost and this represents billions of dollars. But what if we had the technology to delay fruit’s natural degradation process? This is where hexanal can make a difference.

Fruits like mangoes, bananas, papayas and limes are shipped long distances before they get to your table. Many fruits are delicate, and there may be a long period of time that elapses between when the fruit is picked and its arrival in grocery stores and other markets. They’re often picked before they’re truly ripe in order to increase their shelf life.

Even so, globally, up to 40 per cent of all picked fruit can be lost and this represents billions of dollars. But what if we had the technology to delay fruit’s natural degradation process? This is where hexanal can make a difference.

Hexanal is naturally produced by plants to ward off pests; our research at the University of Guelph has found that when it’s applied externally, hexanal can also slow down the aging process.

Like everything else, fruit ages with time. The shrivelling and rot is triggered by the enzyme phospholipase D (PLD), which causes the eventual collapse of the fruit’s membrane. Essentially, fruit membranes are snug, and function like a brick wall of phospholipid bilayers. Phospholipase D breaks the alignment of the bricks, causing the membrane to crumble. Hexanal acts by reducing and slowing the formation of PLD, which in turn slows the collapse of the fruit’s membrane.

In partnership with agricultural and social science researchers in Canada and five other countries, we have tested nine hexanal technologies. These include a spray formulation that gets applied to fruit when they’re still on trees, post-harvest dips, fruit wraps, stickers and sachets embedded with hexanal.

Our findings have implications for consumers, retailers and, more importantly, farmers. For example, when applied as a pre-harvest spray, hexanal can keep fruit on trees longer and keep it fresher after harvest — up to three weeks longer for mangoes.

Hexanal is naturally produced by all plants and is already found as an additive in some food products. Hexanal is also approved by Health Canada as a flavour formula. Our tests of synthesized hexanal sprays, dips and other technologies showed that there were no negative effects on plants, insects or other animals. In addition, hexanal evaporates within 24 hours, which means there’s no residue left on fruit.

Farmers who participated in hexanal testing in Canada and elsewhere were happy with the product both in terms of its effectiveness and bio-safety.

Currently, hexanal for agricultural use is in the two-year regulatory clearance process in Canada and the U.S. Once the process is complete, hexanal formulations are expected to be available for farmer use and can be accessed through companies with a license for production.

That’s a stunning difference, eh?

Funding

At about the same time as the Conversation essay by Subramanian and Finnis, the University of Guelph published (on the Council of Ontario Universities website) a January 27, 2019 news release announcing new funds for the project,

A University of Guelph research project that has already improved the livelihoods of small-scale Asian farmers will further expand worldwide, thanks to more than $4.2 million in federal support announced Friday afternoon.

The project involves innovative packaging developed in part by Guelph researchers using nanotechnology to improve the shelf life of mangoes, a major fruit crop in much of the world.

Already, the technology has helped to significantly reduce post-harvest losses in Sri Lanka and India. Poor storage meant that farmers routinely lost up to 40 per cent of their crops, worth upwards of $800 million a year. The new technology has also boosted per-acre revenue.

New funding support from the International Development Research Centre (IDRC) and Foreign Affairs, Trade and Development Canada will allow researchers to broaden this successful initiative to Kenya, Tanzania, and Trinidad and Tobago.

Researchers will also look at other fruit — bananas, grapes, papaya, nectarines and berries — and investigate ways to commercialize the technologies.

… it will also be a main pillar of the Guelph-East Africa Initiative, which U of G established to bring together stakeholders to support research and teaching in food, health, water, education, environment and community.

“This confirms our commitment to improve agriculture in East Africa and around the world.” [said John Livernois, interim vice-president {research} ]

The project involves the use of hexanal, a natural plant product that delays fruit ripening and aging. Guelph plant agriculture professor Gopi Paliyath holds an American patent on the discovery of hexanal as a post-harvest agent. It’s also an FDA-approved food additive.

The project also involves Guelph plant agriculture professors Paliyath and Al Sullivan; Loong-tak Lim from Food Science; and Elizabeth Finnis, Sociology and Anthropology. Foreign research partners are based at Tamil Nadu Agricultural University, India; Industrial Technical Institute, Sri Lanka; University of Nairobi, Kenya; Sokoine University of Agriculture, Tanzania; and the University of [the] West Indies, Trinidad and Tobago.

Prior to more funding: a memorandum of understanding

I’m having to guess as the document about the memorandum of understanding (MOU) to commercialize hexanal is not dated but it seems to have been produced in March 2018. (Canada’s International Development Research Centre ([IDRC] has a webpage about the memorandum but no memorandum that I could find.) I stumbled across this account of the event where the MOU was signed,

Ms. Jennifer Daubeny, Consulate General of Canada, delivered the special address narrating the significance of Canadian fundingin developing nanotechnologies to reduce post-harvest losses that enables food security in Asian Countries. Dr. K. Ramasamy, Vice Chancellor, Tamil Nadu Agricultural University [TNAU], Coimbatore presided over the function and highlighted the role of TNAU in knitting nanotechnology research framework and serving as a torch bearer in the country. He emphasized that the GAC-IDRC Project helped more than 60 students and researchers, developed two technologies, filed patents for two inventions, extensive infrastructure development besides helping more than 12,000 fruit growers in the State of Tamil Nadu. Dr. Jayasankar Subramanian, Professor, University of Guelph, Canada, explained the evolution of the project till reached the stage of technology delivery to benefit farmers. Dr. K.S. Subramanian, NABARD Chair Professor, TNAU, Coimbatore, lead Principal Investigator of the Project for India presented nanotechnologies developed to assist in the entire value chain from the farm to fork. Mr. Arun Nagarajan, President, Tamil Nadu Fruit Growers’ Association, explained that the fruit growers are eager to use the technology to improve their farm income. Mr. Terence Park, Managing Director, Smart Harvest Agri, Canada, [emphasis mine] bestowed interest to take forward the technologies to the farm gate and signed MOU with TNAU for the Commercialization of the Hexanal Formulation. Dr. G.J. Janavi,Professor & Head, Department of Nano Science & Technology, TNAU, Coimbatore welcomed the gathering and Dr. C. Sekar, Dean, Imayam Agricultural College,Turaiyur, and Co-PI of the Project proposed a formal vote of thanks.

The Canadian Consul General Ms. Jennifer Daubeny visited all the exhibits and interacted with students, scholars and researchers besides the NGO partner Myrada. She was very impressed with the technologies developed by TNAU in collaboration with University of Guelph, Canada, and looking forward to support research programs in the near future. More than 200 Scientists and Diplomats from Canada, students, scholars, university officials participated in the event.

Products launch by ITI, Colombo

Two of the project’s technology outputs -hexanal incorporated ITI Bio-wax and the Tree Fresh Formulation spray [emphasis mine] were transferred to Hayleys Agriculture Pvt. Ltd., a reputed Agro Service provider in Sri Lanka. The products were launched on 22ndMarch 2018 at the Taj Samudra Hotel, Colombo. The chief guest at the event was the Hon. Susil Premajayantha, Minister of Science Technology and Research (Min. ST&R). The guest of honour was H.E. David McKinnon, High Commissioner for Canada in Sri Lanka. Others present included the Secretary to the Min. ST&R, The Chairman and Director General, ITI, Mr Rizvi Zaheed, Hayleys Agriculture and his team, the Chairman, National Science Foundation, Sri Lanka, representative of the Chairman Sri Lanka Export Development Board, representatives from the Dialog mobile service provider, the Registrar of Pesticides, representing the Dir. Gen., of Agriculture, President of the Lanka Fruit and Vegetable Producers, Processors and Exporters Association, leading large scale mango, papaya and pineapple growers, several export and fruit processing company representatives, senior officials from the ITI, the multi-disciplinary ITI research team and our partner from CEPA. The press was also well represented and a total of 100 persons were present on this occasion. The Managing Director Hayles, the two PIs’ of the project, the High Commissioner for Canada, The Minister and for ST&R and the Secretary to the Ministry addressed the gathering and the new video clip on the project was viewed. The new products were jointly uncovered for display by the Hon. Minister and H.E., the High Commissioner. Samples of the products were distributed to the President of the Lanka Fruit and Vegetable Producers Processors and Exporters Association and to two leading mango growers. The Project team also took this opportunity to run a presentation on the various stages of the project and related activities, display posters on their research findings and to print and distribute the pamphlets on the same as well as on hexanal, the latter as prepared by our partners from the University of Guelph. The launch ended with a time of fellowship providing a useful opportunity for networking.

A YouTube video about the product launch of hexanal-based Bio-wax and the Tree Fresh Formulation spray (I don’t know if those were the permanent names or if they are specific to Sri Lanka and other countries will adopt other names) helped to establish the date for the MOU. You can find the video here.

Judging from the media stories, the team in India has provided most of the leadership for commercializing hexanal.

Commercialization 2019 and beyond

To sum up, after a memorandum of understanding is signed and some prototype products have been unveiled in India in 2018 then, in early 2019, there’s more funding announced by IDRC to expand the number of countries involved and to continue research into efforts to save other types of produce.

Moving things along is an August 15, 2019 news item on Agropages.com,

Two nano formulations would be commercialized by the Directorate of Agri business development of Tamil Nadu Agricultural University (TNAU) soon.  

Fruity fresh is a liquid nano formulation containing hexanal that keeps fruits and vegetables fresh for more days. The pre-harvest spray of Fruity Fresh extends the shelf life of mango for two weeks on trees and another two weeks under storage conditions by employing post-harvest dip methodology, Dr. A. Lakshmanan, Professor and Head, Department of Nano Science and Technology told a meet on “Linking Nano Stakeholders” held at the University.  

Hexanal has also been successfully encapsulated in polymer matrix either as an electro spun fibre matrix (Nano sticker) or nano-pellets that extends shelf life of fruits by 1-2 weeks during storage and transportation, he said.  

This sticker and pellets technology is highly user friendly and can be placed inside the cartons containing fruits during transport for enhancing the freshness.

According to a November 5, 2019 article by Pearly Neo for foodnavigator-asia.com, there is pricing for four products. Nano Sticker and Nano Pellet each will cost $US 0.028 and the spray, Fruity Fresh, will cost $US 4.23 to $US 5.65 for a one liter bottle diluted in 50 liters of water (for use on approximately five trees) and the Fruity Fresh dipping solution at $US 0.0071per kg.

As far as I’m aware none of these products are available in Canada but there is a website for Smart Harvest Agri, Canada although the name used is a little different. First, there’s the Federal Corporation Information listing for Smart Harvest Agritech Limited. You’ll notice there are two directors,

The company’s Smart Harvest website doesn’t list any products but it does discuss something they call “FRESHXtend technology” for fruits and vegetables.

Final comment

I sometimes hear complaints about government funding and what seems to be a lack of follow through with exciting research work being done in Canada. I hope that in the months to come that this story of an international collaboration, which started with three countries and has now expanded to at least six countries and has led to increased food security with an environmentally friendly material and commercialization of research, gets some attention.

From the few sources I’ve been able to find, it seems India and Sri Lanka are leading the commercialization charge while Canada has contributed to an Asian-led project which has now expanded to include Kenya, Tanzania, and Trinidad and Tobago. Bravo t them all!

Hexanal and preventing (or diminishing) fruit spoilage

More mangoes thanks to an Indian-Sri Lankan-Canadian nanotechnologyresearch project is a Feb. 9, 2015 posting where I highlighted (not for the first time) a three country research project utilizing hexanal in boxes for fruit (mango) storage,

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.

In the Feb. 9, 2015 posting I was featuring the project again as it had received new funding,

  • 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.

A Dec. 29, 2015 article (Life of temperate fruits in orchards extended, thanks to nanotech) in The Hindu newspaper provides an update on the collaboration,

Talking to mediapersons after taking part in a workshop on ‘Enhanced Preservation of Fruits using Nanotechnology Project’ held at the Horticultural College and Research Institute, Periyakulam near here on Monday [Dec. 28, 2015], he [K.S. Subramanian, Professor, Department of Nano Science and Technology, TNAU, Coimbatore] said countries like Sri Lanka, Tanzania, Kenya and West Indies will benefit. Post-harvest loss in African countries was approximately 80 per cent, whereas it was 25 to 30 per cent in India, he said.

With the funds sanctioned by Canadian Department of Foreign Affairs, Trade and Development and International Development Research Centre, Canada, the TN Agricultural University, Coimbatore, involving scientists in University of Guelph, Canada, Industrial Technology Institute, Colombo, Sokoine University of Agriculture, Tanzania, University of Nairobi [Kenya], University of West Indies, Trinidad and Tobago, have jointly developed Hexanal formulation, a nano-emulsion, to minimise post harvest loss and extend shelf life of mango.

Field trials have been carried out successfully in Dharmapuri and Krishnagiri on five varieties – Neelam, Bangalura, Banganapalle, Alphonso and Imam Pasand. Pre-harvest spray of Hexanal formulation retained fruits in the trees for three weeks and three more weeks in storage.

Extending life to six to eight weeks will benefit exporters immensely as they required at least six weeks to take fruits to European and the US market. Existing technologies were sufficient to retain fruits up to four weeks only. Domestic growers too can delay harvest and tap market when in demand.

In a companion Dec. 29, 2015 article (New technologies will enhance income of farmers) for The Hindu, benefits for the Indian agricultural economy were extolled,

Nano technology is an ideal tool to extend the shelf life and delay in ripening mango in trees, but proper bio-safety tests should be done before introducing it to farmers, according to Deputy Director General of ICAR N.K. Krishnakumar.

Inaugurating a workshop on Enhanced Preservation of Fruits using Nanotechnology Project held at the Horticultural College and Research Institute at Periyakulam near here on Monday [Dec. 28, 2015], he said that bio safety test was very important before implementing any nano-technology. Proper adoption of new technologies would certainly enhance the income of farmers, he added.

Demand for organic fruits was very high in foreign countries, he said, adding that Japan and Germany were prepared to buy large quantum of organic pomegranate. Covering fruits in bags would ensure uniform colour and quality, he said.

He appealed to scale down use of chemical pesticides and fertilizers to improve quality and taste. He said dipping mango in water mixed with salt will suffice to control fungus.

Postgraduate and research students should take up a problem faced by farmers and find a solution to it by working in his farm. His thesis could be accepted for offering degree only after getting feedback from that farmer. Such measure would benefit college, students and farmers, Mr. Krishnakumar added.

It’s good to get an update on the project’s progress and, while it’s not clear from the excerpts I have here, they are testing hexanal with on fruit other than mangoes.

First ever Nanoscience and Nanotechnology Symposium in English-speaking Caribbean

A July 12, 2014 news item on Nanowerk heralds this new International symposium on nanoscience and nanotechnology,

The ‘International Symposium on Nanoscience and Nanotechnology’ will be hosted at The University of the West Indies (UWI), St. Augustine [in Trinidad and Tobago], from July 15-17, 2014.

I wish them all the best. They seem (judging by the institutions represented) to have attracted a stellar roster of speakers.

Authenticating chocolate and a bit about coffee

Apparently, not all premium chocolate is actually premium, like wine, expensive, premium product can be mixed with a more common variety to be sold at the higher, premium price.  Now, scientists in a collaboration which spans the US, China, and Trinidad and Tobago have found a way to authenticate premium chocolate according to a Jan. 15, 2014 news release on EurekAlert,

For some people, nothing can top a morsel of luxuriously rich, premium chocolate. But until now, other than depending on their taste buds, chocolate connoisseurs had no way of knowing whether they were getting what they paid for. In ACS’ Journal of Agricultural and Food Chemistry, scientists are reporting, for the first time, a method to authenticate the varietal purity and origin of cacao beans, the source of chocolate’s main ingredient, cocoa.

Dapeng Zhang and colleagues note that lower-quality cacao beans often get mixed in with premium varieties on their way to becoming chocolate bars, truffles, sauces and liqueurs. But the stakes for policing the chocolate industry are high. It’s a multi-billion dollar global enterprise, and in some places, it’s as much art as business. There’s also a conservation angle to knowing whether products are truly what confectioners claim them to be. The ability to authenticate premium and rare varieties would encourage growers to maintain cacao biodiversity rather than depend on the most abundant and easiest to grow trees. Researchers have found ways to verify through genetic testing the authenticity of many other crops, including cereals, fruits, olives, tea and coffee, but those methods aren’t suitable for cacao beans. Zhang’s team wanted to address this challenge.

Applying the most recent developments in cacao genomics, they were able to identify a small set of DNA markers called SNPs (pronounced “snips”) that make up unique fingerprints of different cacao species. The technique works on single cacao beans and can be scaled up to handle large samples quickly. “To our knowledge, this is the first authentication study in cacao using molecular markers,” the researchers state.

Here’s an image, provided by the researchers, illustrating their work,

This story reminded me that coffee too is sold at premium prices. Billed as the most expensive coffee in the world, Kopi Luwak, is harvested, so they say, from civet excrement and I have to wonder how anyone could authenticate that a bean had actually passed through a civet’s gastrointestinal tract and out the other end. I’ve also wondered how the practice of plucking coffee beans from civet excrement started (from the Kopi Luwak Wikipedia essay; Note: Links have been removed) here’s an answer to the second question,

The origin of kopi luwak is closely connected with the history of coffee production in Indonesia. In the early 18th century the Dutch established the cash-crop coffee plantations in their colony in the Dutch East Indies islands of Java and Sumatra, including Arabica coffee introduced from Yemen. During the era of Cultuurstelsel (1830—1870), the Dutch prohibited the native farmers and plantation workers from picking coffee fruits for their own use. Still, the native farmers wanted to have a taste of the famed coffee beverage. Soon, the natives learned that certain species of musang or luwak (Asian Palm Civet) consumed the coffee fruits, yet they left the coffee seeds undigested in their droppings. The natives collected these luwaks’ coffee seed droppings, then cleaned, roasted and ground them to make their own coffee beverage.[11] The fame of aromatic civet coffee spread from locals to Dutch plantation owners and soon became their favourite, yet because of its rarity and unusual process, the civet coffee was expensive even during the colonial era.[citation needed]

I guess that in the future when you eat premium chocolate you can be sure that you’ve gotten what you paid for. As for coffee, I’m sure that industry is working on its authentication processes too and in the meantime, you’ll have to rely on your palate.
