Maple syrup , often foretell Canada ’s “ liquid gold , ” has long been atarget for fraudulent activeness , such as the dilution or substitution with other syrups , due to its high requirement .
Amid terror from the United States of increased duty and the imposition of abaseline duty of 10%on all imports that are n’t compliant with the Canada - United States - Mexico Agreement , increase maple sirup fraud is a opening .
solid food sham , oreconomically motivated debasement , is thedeliberate misrepresentationof food for economic gain . This can include the transposition , dilution , addition and/or the remotion of ingredients . Mislabelling of Cartesian product is another form of intellectual nourishment humbug that can occur at any point in the supplying chain , from farm to fork . Food put-on is a multi - billion - buck industryand puzzle serious risks . It can harm consumer health , tarnish brand reputations and value , threaten the keep of logical manufacturer and even handicap biodiversity and conservational drive .

Thethreats of tariff on Canadian good by the U.S. , which includes maple syrup andequipment used to make it , has raised concern on both side of the border about price increase and supply shortage . Canadaproduces more than 70 % of the world ’s maple syrupand Québec is the capital of this yield . In 2024 , the province export around$450 million worth of maple syrup to the U.S.
Historic increases in food fraud
Historically , intellectual nourishment pseudo has increase during harsh economic times , growing fiscal pressure , pandemic , climate incidents , wars , supply Sir Ernst Boris Chain disruptions or any other event that destabilizes the balance between solid food provision and demand . These circumstances often increase solid food prices , create an bonus for fraudsters to exploit the system .
From 2020 to 2024,the world faced significant supply Ernst Boris Chain disruptionsdue to the covid-19 pandemic , regional wars and significant climate events . Unsurprisingly , solid food humbug cases have increase tenfold , according to recent estimate . Threats of higher tariffs could further kick in to this problem by increase the likelihood that fraudsters willsubstitute high - value foods for lower - note value products .
Given what we have learned from past cases of solid food fraud , threats of increased tariffs get uncertainty in the supply chain , increase the risk of deceitful maple syrups from enter the marketplace . To battle this threat , there is a need for rapid , material - time and cost - effective methods to try out maple syrup for legitimacy .
Analyzing the distinctive features in maple syrup fluorescence fingerprints (glow), using AI, to differentiate pure from adulterated maple syrup.
Methods for testing maple syrup
Since the 1980s , variousmethods and toolshave been train or used to discover maple syrup debasement . However , nutrient fraudsters continuouslyadapt to skirt catching , build it increasingly more hard to screen for maple syrup debasement . The more complex the testing methods , the more difficult they are to circumvent .
Traditionally , maple sirup quality testing involves measuring the dissolve cabbage content in sirup through a unit of measure known as degrees Brix . One degree Brix is equivalent to 1 % saccharide . However , program may belimited if unknown or non - formal adulterantsare used .
As put-on technique become more sophisticated , young approaches are needed to ensure the authenticity of maple syrup . Non - targeted nutrient analytic method acting , such as fluorescence spectroscopy , allow for the masking of a wide range of samples , creating a fingermark of a sample . The fingerprints can be compare to a reference library of profiles , or multiple attributes specific to maple syrups , rather than just one .
Testing maple syrup for glowing compounds
A late studyby our research team at the University of Guelph ’s Corradini Lab explore howfluorescence fingerprint can be used to detect maple sirup adulteration . Fluorescence fingerprinting works by examining howinternal molecules in maple syrup glow when exposed to ultraviolet light and visible Light Within . These unique , glow fingerprint earmark for the espial of mark or features that may be declarative of maple sirup pseudo .
Our study explored the debasement of amber and dark maple syrups , with common maple sirup adulterant — namely beet , corn and rice syrups — at values ranging from one to 50 % .
We mapped singular and distinctive features in the fluorescence fingerprint , which were then used for secern perfect from adulterated syrups . When exposed to ultraviolet radiation and seeable luminousness , maple sirup feature film changed depending on the eccentric — beetroot , Zea mays or Elmer Reizenstein syrups — and amount of adulterator .
AI and machine learning for improved detection
Using the markers of maple syrup individuality , we were capable to apply AI to analyze multiple fluorescent lineament at the same time . This allowed for the recognition of virgin maple syrups from adulterants , with accuracy ranging from 75 to 99 % .
In fact , analyse the fluorescence fingerprints of staring and adulterated syrup with the assistance of AI and machine learning techniques improved detection by up to 30 % , and name adulterator at levels less than two per centime .
However , expanding the fluorescence fingermark book of facts library can improve the accuracy and reliableness of results . AI models often require very declamatory and wide databases . This will be essential for understanding and accounting for how broker like the surround , geographic localization and processing circumstance may affect the maple syrup lambency . The function of AI to analyze fluorescent markers in maple syrup could allow for speedy and effective identification of suspicious fraudulent samples .
With the increased risk of food fraud due to threats of increase U.S. import tariff on Canadian product , combine AI and maple sirup fingerprinting can find maple syrup put-on . This will control that consumer receive secure , high - quality foods while protecting the identity of one of Canada ’s most iconic products .
