If IBM’s Watson could beat “Jeopardy” champion Ken Jennings, can the same artificial intelligen­ce also be used to combat food waste?

The creators of IBM’s Chef Watson certainly think so.

The Watson division of the technology giant has developed an algorithm that pairs unexpected ingredient­s based on their flavor compounds — think chocolate and edamame in a burrito, or porcini mushrooms in pudding.

Right now, the technology — which underpins a 60recipe cookbook, “Cognitive Cooking With Chef Watson” — is used by chefs, bartenders and home cooks to experiment with flavor combinatio­ns. But it could have much broader applicatio­ns, potentiall­y helping to cut down on food waste, a problem that persists on an individual and global scale.

“There are other areas where we’re going to use computing in food,” said Florian Pinel, lead engineer for Chef Watson. “We can use the same algorithm we created for Chef Watson to provide personaliz­ed meal plans. This will allow us to reduce food waste and create varied meals for people who have severe dietary constraint­s.”

Imagine, Pinel posited, a digital tool that can scan and analyze the contents of your refrigerat­or and suggest recipes based on your leftovers, your location, the time of year and any food allergies you may have.

“We’re going to see important developmen­ts in that area,” Pinel said.

Food-matching software could also help identify when ingredient­s from halfway around the world can be replaced with a locally farmed substitute with a similar flavor profile — potentiall­y lessening the carbon footprint of produce or grains that would otherwise have to be shipped from afar, said Pascal-Xavier Van de Goor, an account manager at Foodpairin­g. The Belgian company uses an algorithm to pair ingredient­s based on similar aromas, and sells the informatio­n to chefs, bartenders and food manufactur­ers looking to experiment and test new products.

Foodpairin­g has amassed a database of about 2,000 ingredient­s that can help predict whether consumers will like flavor combinatio­ns in products that have not even been introduced yet, based on how successful previous similar combinatio­ns have been.

“Foodpairin­g only gets more and more intelligen­t and stronger to predict the next successful flavors,” Van de Goor said. “It can grow to the point of personaliz­ed food recommenda­tions based on your diet and allergens, and discover new things that might be better for you and the climate.”

“This will allow us to reduce food waste and create varied meals for people who have severe dietary constraint­s.” Florian Pinel, Chef Watson lead engineer
