Combating Olive Oil Fraud Using GC–IMS and FGC-Enose
LCGC Europe, 2021 The adulteration of high-quality foods is big business. Typical adulteration of olive oil involves the use of other types of oil, such as seed oils or pomace oils, the introduction of re-esterified oils, or the creation of mixtures with refined oils to create a lower quality product that can still be sold at a premium price.
