Oils Authenticity Summary Data

​Canadian Food Inspection Agency collects samples of olive oils and other expensive oils to verify accurate representation. The olive oil samples are tested for authenticity, adulteration, substitution or dilution with cheaper oils by assessing the sterol and fatty acid profile by gas chromatography. The sampled expensive oils are tested to determine if the fatty acid and sterol profiles, and other parameters, meet the standard for these oils by gas liquid chromatography. **Additional Information:** + CFIA's [Food Fraud Annual Report (2024 to 2025)](https://inspection.canada.ca/en/about-cfia/science-and-research-cfia/our-research-and-publications/food-fraud-report-2025) + CFIA's [Food Fraud Annual Report 2023 to 2024](https://inspection.canada.ca/en/about-cfia/science-and-research-cfia/our-research-and-publications/food-fraud-report-2024) + CFIA's [Food Fraud Annual Report 2022 to 2023](https://inspection.canada.ca/en/about-cfia/science-and-research-cfia/our-research-and-publications/food-fraud-report-2023) + CFIA's [Food Fraud Annual Report 2021 to 2022](https://inspection.canada.ca/en/about-cfia/science-and-research-cfia/our-research-and-publications/food-fraud-report) + CFIA's…
