Genuine maple syrup is a treat for the taste buds, whether you prefer light golden varieties or robust darker syrups. But sometimes batches can have off-putting flavors. Scientists at the University of Montreal in Quebec, Canada, have developed an artificial “tongue” using gold nanoparticles that can weed out bad batches early on. It’s not so much an electronic device as a simple, portable chemistry test that detects a color change when an off flavor is present in a sample, according to\u00a0a recent paper<\/a> published in the journal Analytical Methods.<\/p>\n

“Especially here in Canada, we take maple syrup for granted,” said co-author Jean-Fran\u00e7ois Masson of the University of Montreal “But it is much more complicated than we had anticipated. It has some of the same complexities as fine wine and whiskey.”\u00a0Quebec is the largest producer of maple syrup, accounting for about 70 percent of the world’s supply.<\/p>\n

He is not referring to cheap knockoffs whose primary ingredients are high-fructose corn syrup with imitation maple flavoring. To be considered a true maple syrup, at least in Canada, a product must be made entirely from maple sap\u00a0collected from maple trees, usually sugar maple, red maple, or black maple varieties.\u00a0Maple syrup is mostly sugar, water, and a small amount of organic molecules that are responsible for the final product’s flavor profile. Those compounds account for just 1 percent of the content, but it is a crucial 1 percent, determining whether a given syrup is caramelized, smoked, salty, or woody, among the 60 or so possible categories.<\/p>\n<\/div>\n
