New portable sensor detects food allergens in minutes

Guelph – An estimated 2.5 million Canadians report an allergy to at least one food, according to Food Allergy Canada. Peanut allergies alone affect the lives of approximately two in every 100 Canadian children.

As the list of food allergens continues to grow, there is a genuine need for a quick and accurate allergen test whether you are scrutinizing every snack for your child, or conducting randomized testing on a food production line. Current allergen testing can take hours, when minutes can make all the difference.

A new technology developed at the University of Guelph successfully shaves valuable hours off accurate testing, and will soon be widely available in Canada.

Prof. Suresh Neethirajan has developed a new test that accurately pinpoints and quantifies the presence of food allergens. Designed to deliver results in a matter of minutes, the test can be used by consumers, restaurants and food manufacturers for on-site testing in a user-friendly format.

“What we’ve developed is one of a kind,” explains Neethirajan, an associate professor in bioengineering in the School of Engineering at Guelph. “We have filed two U.S. patents to license our technology, and are in discussions with a major multinational company to bring this technology to consumers, and we’re working with the food industry to bring this testing to the production line.”

The new biosensor provides a one-step assay to test for the presence of food allergens and is intended for anyone who wants to avoid certain food ingredients.

“We have successfully tested the technology to measure food allergens including shrimp, egg and peanuts, and are working to expand to other food allergens,” says Neethirajan.

Video: Spring weed control in winter wheat with Broadway® Star (pyroxsulam + florasulam)

#CortevaTalks brings you a short update with Cereal Herbicides Category Manager, Alister McRobbie, on how to get the most out of Broadway® Star.

Significant populations of grassweeds, including ryegrass and brome, can threaten winter wheat yields. Spring applications of a contact graminicide, such as Broadway Star from Corteva Agriscience, can clear problem weeds, allowing crops to grow away in the spring.

Broadway Star (pyroxsulam + florasulam) controls ryegrass, sterile brome, wild oats and a range of broad-leaved weeds such as cleavers. It can be applied to winter wheat up until GS32, but the earlier the application is made, the smaller the weed, and the greater the benefit to the crop. Weeds should be actively growing. A good rule of thumb is that if your grass needs cutting, conditions are right to apply Broadway Star.
