Use the of C3 CO2 fixation cycle by the sugar maple (Acer saccharum Marsh.), a dicotyledenous plant, and the C4 carbon fixation cycle by 2 monocotyledenous plants, corn and cane, results in a physiological discrimination between 13C and 12C isotopes. Determination of the 13C/12C ratio of maple syrup by mass spectrometry can be used to detect adulteration with cane and corn sugars. Four samples of pure maple syrup and 3 adulterated maple syrup samples were analyzed in a collaborative study. Stable C isotope analysis can determine authenticity of maple products. Samples with .delta.13C values less negative than -23.49.permill. can, with a high degree of confidence (95%), be classified as adulterated.
