Honey is an easy target for food fraud and adulteration with sucrose, high fructose corn syrup, molasses and other sugars are not uncommon. To quickly identify adulterants, a method using Raman spectroscopy and pattern recognition analysis was developed. To verify the method, 97 samples were tested with the new method, and the tests confirmed with HPLC, with the result that 17% of the commercial honey samples showed fraud from added sugars.

Cinnamon is in high demand worldwide, with Ceylon cinnamon or true cinnamon (Cinnamon verum) the most sought-after and higher priced variety. It is therefore tempting to “cut” Ceylon cinnamon with cheaper cassia cinnamon. Previous detection methods for such adulterations included HPLC testing or DNA barcoding, which was time consuming and could only be applied by experts. New FT-NIR (Fourier transform near-infrared) and FTIR (Fourier transform infrared) spectroscopic methods in combination with multivariate analysis enable quick detection of cinnamon adulteration.
