Food Fraud Quick Bites. Fraud Is the Spice Of Life
High adulteration rate is found in black pepper and cumin powder.
The high value of spices makes them one of the most popular targets for intentional adulteration. Researchers in Brazil developed an efficient method for fraud detection: Near-infrared spectrometer (NIR) associated with chemometrics. This method is able to detect adulterants like corn flour and cassava in spice samples, revealing a high rate of adulteration, between 62% for commercial black pepper and 79% for cumin samples.
