Maple syrup, the concentrated sap of Acer saccharum March, is sought after for its unique flavour and taste. As a popular and high value product, it is increasingly susceptible to adulteration by other sugar syrups. This review looks at most recent advances in the analytical methods used for detecting the different types of maple syrup adulteration.It concludes that SpectrAcer and nuclear magnetic resonance (NMR) are the most efficient methods for detection of maple syrup adulteration. SpectrAcer, an automated spectroscopy sytem developed by the Canadian company Acer, based reflected light at different wavelengths using the syrup's fluorescence properties with UV, and sugar composition at other wavelengths.
