How Canadian Technology Is Tackling The Food Waste Crisis

How homegrown Canadian tech is tackling our $31 billion food waste crisis.

The issue of food waste has grown from your parents telling you to finish what's on your plate into one of the defining challenges of our era. Despite rising food insecurity, $31 billion of it is wasted every year in Canada, a number soaring to $1 trillion worldwide as 30 per cent of food goes uneaten.

Yes, some of that is still your fault if you put leftovers in the trash instead of Tupperware, but the vast majority of food waste happens at production, processing and retail levels rather than on the consumption side.

To help address this, France famously passed unanimous legislation requiring supermarkets to either give unsold food to charity or send it to farmers for use as feed and fertilizer. Here in Canada, food rescue organizations like Second Harvest help get unspoiled food from retailers, manufacturers, restaurants and caterers to charities, delivering ingredients for over 22,000 meals daily.

But we live in hi-tech times, so technology is also being used as a weapon in the war on food waste. Here's a look at how homegrown Canadian tech is trying to tackle our food waste crisis.

Jay Subramanian, a plant agriculture professor at the University of Guelph, and his team of biotech scientists have devised a food spray that the CBC reports "uses a nanotechnology-based application of hexanal, a natural plant extract that prevents fruit spoilage."

This enzyme-inhibiting hexanal slows ripening by preserving a fruit's cellular walls, extending shelf life by as much as 50 per cent. Mangoes keep fresh up to 23 days, bananas up to 40 days and peaches and nectarines last another 10 days beyond their current single week. It also increases farmer revenues 15 per cent.

Fruit is one of food waste's biggest culprits -- 30 percent of fruits and veggies don't even get on store shelves -- making this invention a potentially huge player in addressing the issue.
Hyperspectral Chemical Imaging

About 18 per cent of food waste happens at the manufacturing level, according to a report by Ontario's Provision Coalition, "the food and beverage manufacturers' one-stop source for sustainability."

One solution to reducing that waste may be "hyperspectral chemical imaging technology for production line grading and sorting of leafy greens, carrots and potatoes," reports Food in Canada, a food and beverage processing industry publication.

The initiative is a collaboration between Ippolito Fruit & Produce, Riga Farms, EarthFresh Foods and Amazing Grains working with Ontario chemical imaging company P&P Optica and industrial equipment company Axiom Millwrighting & Fabrication. The University of Guelph and Conestoga College will be in charge of testing the technology's effectiveness.

"Currently, many produce manufacturers in Canada are using aging technology for sorting and grading. At Ippolito, we connected with our industry peers to explore and then implement new technology – technology that has broader food industry application and will be shared with companies across the country," CEO Joel Ippolito told Food in Canada.
Apps: Ubifood

Inspired by a friend's sushi shop tossing out unsold food at day's end, despite being sold at a discount, Ubifood founder Caroline Pellegrini decided that an app would be the best way to connect consumers and retailers.

Currently exclusive to Montreal, Ubifood gives geolocation-based real-time push notifications to inform users of discounted food in their area.

The sales pitch is that it makes money for cafes, bakeries and restaurants while saving money for customers and, most importantly, reducing food waste.

"Everybody benefits. The consumers, retailers, and the planet – all at once," Pellegrini told CBC.
Okanagan Specialty Fruits

Despite continuing if unfounded public skepticism over GMOs, B.C.-based Okanagan Specialty Fruits has received approval by Canadian and American authorities to sell their signature non-browning Arctic Apple.

Developed in Granny Smith and Golden Delicious varieties, this first approved biotech apple resists browning when sliced or bruised because the genes that trigger the oxidization process have been replaced with non-browning ones.

According to CP, the Canadian Food Inspection Agency said Arctic Apples "are as safe and nutritious as traditional apple varieties" while Health Canada concluded the GMO apple "is safe for consumption, still has all its nutritional value and therefore does not differ from other apples available on the market."

They're scheduled to start arriving in the U.S. later this year and will be available for sale in Canada by fall 2017.

While not invented here, this summer Health Canada is launching a public consultation on a plan to irradiate ground beef to kill bacterial microorganisms like E. coli and salmonella in the wake of outbreaks like Alberta's XL Foods in 2012.

CBC reports that a recent government review has "determined that ground beef treated with irradiation is safe to eat and retains its nutritional value, taste, texture and appearance."

Irradiation, which involves exposing food to ionizing radiation like gamma rays or X-rays, is already used in Canada for potatoes, onions, wheat, flour and spices.

As well as increasing food safety, irradiation also prevents premature spoilage to increase shelf life and reduce food waste.

Tim Sly, a professor in the School of Public Health at Toronto's Ryerson University, told CBC that by preventing massive recalls, irradiation could avoid the wastage of millions of pounds of food.

Hilary Benn, the former environment minister, said people should ignore "best before" labels and decide for themselves if food is still good.Benn said in 2009 that "best before" dates served little useful purpose and could be cheerfully ignored - they just mean when the food is at its freshest.He said: "There's 'use by' and that's very important because that's food safety; but when it comes to 'sell by' or 'best before', I think we as consumers [need to] understand better what those labels mean.|
Eggs last a lot longer than you think
The Mail commissioned the West Yorkshire-based FoodTest Laboratories to compare batches of Lion eggs, bought at Tesco.The company kept two batches of eggs for a fortnight, one at room temperature, the other at a typical fridge temperature of 6c. Samples from both batches were regularly tested eg. for E.coli, salmonella, listeria. There was no difference whatsoever between the two batches. Both remained bacteria-free and good to eat.
You can probably eat mouldy salami

The US Department of Agriculture says as long as you scrub the mould off, then it's totally fine."It is normal for products like this to acquire surface mould," the Safe Food Handling fact sheet says.Don't eat any mouldy cooked meat though, for god's sake.
And some kinds of mouldy cheese

For cheeses where mould isn’t part of the processing, mold generally can’t get deep into the product. For hard cheeses, such as Asiago, Pecorino, Parmesan and Cheddar, lop off at least 1 inch around and below the mold spot (to avoid cross-contamination, be careful not to touch the mold with the knife).Source: USDA
And "firm" fruit and veg, even if it's a bit mouldy
Getty Images
So think, cabbage, peppers, carrots. Like the cheeses, dense fruits and vegetables are not easily penetrated by mould. The same rule of thumb applies to firm produce: cut off at least an inch around and below the mould spot (again, not touching the mold with your knife) before using.Source USDA
You can pretty much ignore sell-by-dates on canned food
As long as it smells OK and looks OK when you open it.There have been cases where canned food survived almost 100 years with no microbial growth whatsoever.
Butter lasts way past its sell-by-date
According to the experts at Still Tasty, butter lasts about 2 weeks after its expiration date. Frozen butter lasts up to 9 months longer.
Pickles basically last for a year

Open jars of pickles stay good for a whole year in the refrigerator. The same goes for olives and capers, according to Still Tasty.
Most spices last 2-3 years past their expiration date

There's absolutely no need to throw them out before then, according to
Bagged salads? Don't go there

Your Food Will Likely Have Some Mold, Poop And Bugs In It. And That's Cool With The FDA.
Ever open a fresh bag of cereal and notice something a little... off about it? That is likely not just your imagination. According to the FDA's Defect Levels Handbook, a number of foods can legally contain up to "maximum levels of natural or unavoidable defects in foods for human use," including "insect filth," "rot" and "Mammalian excreta."
The FDA Has NEVER Safety Tested Genetically Engineered Foods

According to the Organic Consumers Association, the United States is the only developed country that does not require testing for safety of GE foods.
Your Meat Takes An Ammonia Bath Before Hitting Grocery Store Shelves
Ammonia, a main ingredient in fertilizer and household cleaners, is apparently an appropriate way to kill bacteria in meat. Sure, it may be corrosive and can cause severe injury, but according to a USDA official, “it eliminates E. coli to the same degree as if you cooked the product."
The FDA And Monsanto Have A VERY Close Friend In Common
Michael R. Taylor, pictured, has had quite the colorful career path. Bouncing between the FDA and Monsanto, Taylor is the poster boy for the government's controversial "revolving door" issue. The FDA's current Deputy Commissioner of Food is responsible for the substantial equivalence policy, which is used as a weapon against the "right to know" argument for GMO labeling.
The Government Is All For Feeding Animals Arsenic
This past September, the FDA ordered a number of arsenic-based drugs to be withdrawn from farm animal feed, an ingredient that had been used since the 1940s. While it might seem like a step in the right direction, consider this: The FDA only passed down the decision after food groups threatened to sue the agency. Before the ban, about 70 percent of U.S. poultry were being fed arsenic-based drugs, and even with the new legislation, one of the 4 banned drugs can still be fed to turkeys.
The Orange Stuff On Your Favorite Cheesy Snack Is A Known Carcinogen
Red #40, the most widely-used food dye, and Yellow #6, the third most widely-used food dye, are linked to hyperactivity, migraines and possibly cancer. Although some of these colorings have already been banned in Europe, the FDA is still refusing to take them off the U.S. market.
'Whole Grain' Foods Are Often Completely Processed
You might think that "whole grain" foods are exactly that -- completely untouched, full-fledged grains. However, the FDA says that as long as the naturally occurring nutrients and parts are added BACK into the food at the end, you can take them out along the way and add in a number of other additives and flavorings. So a processed breakfast cereal with tons of sugar can bear the "whole grain" mark as long as the same nutrients have (artificially) ended up back in the product.
Food Containing Trans Fats Can Still Bear A 'Zero Trans Fats' Label
Think those chips are free of harmful trans fats? Think again. If a food contains less than 0.5 grams of trans fats per serving, the label can claim it has "0 grams of trans fats." Although the FDA recently began a campaign to claim that partially hydrogenated oils are no longer GRAS (generally recognized as safe), legislation has yet to be made against them. If you consume a number of these foods per day, you could be racking up dangerous fats without even knowing.
The FDA Is A Big Ol' Softie When It Comes To Criminal Prosecution
In 2010, the FDA agreed to crack down on misdemeanor crimes after a governmental report found the agency to be too soft on corporations that break the rules. Congress found that the FDA's Office of Criminal Investigations fell short in comparison to similar agencies, in response to which the FDA admitted they were working on “developing meaningful performance measures.”
25+ Countries Have Banned rBGH, But That Doesn't Bother The FDA
rBGH is a hormone that has been banned in a number of countries, including Australia, New Zealand, Canada, Japan, and the European Union. Although the FDA has found that rBGH (also known as rBST) is both safe and effective, a 2009 USDA study found that less than 17 percent of cows were being injected with the hormone. Even WITHOUT an FDA ban, people know synthetic hormones are best kept out of the food system.
