Counterfeit and adulterated edible oils are a growing concern, and this session examines new approaches to verify authenticity. Attenuated total reflectance Fourier-transform infrared spectroscopy and machine learning are being used to identify and classify oils and margarines with a high degree of accuracy. Raman spectroscopy can also recognize adulterated, counterfeit, and contaminated oils at reduced cost. In addition, the session will cover work being done to establish the concentration of important chemical compounds to identify pure avocado oil.
