What is "fake" extra-virgin olive oil?
In most cases, fake extra virgin olive oil is simply a lower grade of virgin or refined olive oil that has been mislabelled as extra virgin olive oil. Such oils may have been processed or diluted with other oils (such as sunflower, soybean, canola or rapeseed oils) in order to boost profits, and therefore failed to meet the high testing standards of extra virgin olive oil as a result. Fake oils may also have pigments such as chlorophyll or β-carotene added to improve their appearance and quality. Fraud can also involve masking where the product was made, deceptive labelling or the use of false expiration dates
