This metric matters because overheating oil can create off-flavors and potentially harmful compounds, so understanding where canola oil stands is essential for both home cooks and culinary professionals. How Canola Oil Compares to Other Common Oils When placed alongside other kitchen staples, refined canola oil holds its own in the smoke point department.
Safe Reuse of Canola Oil After Frying: Tips to Maintain Smoke Point and Avoid Off-Flavors
In contrast, refined canola oil undergoes additional processing, including bleaching and deodorization, which strips away impurities and raises the smoke point to between 400°F and 450°F (204°C and 232°C). Unrefined or "cold-pressed" canola oil retains more natural compounds, such as phospholipids and free fatty acids, which lower its smoke point to roughly 350°F to 400°F (177°C to 204°C).
This versatility explains why many professional kitchens reach for canola when a reliable, high-heat fat is needed. Canola oil sits high on the list of popular cooking fats, prized for its neutral flavor and versatility.

Beyond this threshold, the oil begins to degrade, releasing free fatty acids and potentially forming acrolein, a compound that contributes to the harsh taste and odor associated with burnt food. Factors that influence smoke point include the oil’s fatty acid composition, purity, and the presence of free fatty acids, which lower the temperature at which smoking begins.
