Maple syrup includes pure maple syrup, which is made by boiling down the sap of the sugar maple tree, and low-priced products made by adding cheap corn syrup. Because the main component of pure maple syrup is sucrose and low-priced products are primarily glucose, the difference between the two can be clarified by a qualitative analysis using FTIR. It is also possible to calculate the concentrations of the various sugars contained in products by a chemometric analysis.

The Shimadzu IRTracer™-100 Fourier transform infrared spectrophotometer (FTIR) was used. Measurements were carried out by the 10-bounce attenuated total reflectance (ATR) method using a horizontal ATR accessory (HATR). The maple syrup samples were diluted to 10 % w/w with water and dripped on the ATR prism (ZnSe) for measurement
The concentrations (% w/w) of fructose, glucose, and sucrose in various maple syrups were calculated by chemometrics by the PLS (partial-least squares) method. This analytica lmethod makes it possible to obtain the amounts of target substances in multicomponent mixtures.

Chemometric analysis enables quantitative analysis of multiple components contained in maple syrup and other food products, and FTIR measurement by the ATR method is extremely simple. Thus, a combination of these techniques is the ideal solution for quality control when qualitative analysis and quantitative analysis of the components of foods is necessary.
