The Science of Smoke Point and Stability When oil is heated beyond its smoke point, it begins to break down, producing acrid smoke and harmful free radicals. Canola oil is a close runner-up, offering a similarly high smoke point at a more accessible price point, while vegetable shortening delivers the ultimate crispness due to its high saturated fat content.
