It was possible, however, to discriminate between the A. salmiana syrups and the sugar cane syrups. The MIR spectra of the agave syrups revealed differences according to the source species. Because of the high carbohydrate content of both syrups, strong carbohydrate absorption bands were observed for the A. salmiana syrup in the sucrose region (997 cm−1) and for the A. tequilana syrup in the fructose region (1062 cm−1).
