The last several years multiple food fraud cases have surfaced. Due to its premium price and a production volume
of approximately 3 million tonnes per year olive oil is vulnerable for adulteration by the addition of cheaper vegetable

Differential Scanning Calorimetry (DSC) has been suggested as a possible method for verifying quality [2],
