Additionally, many commercial "vegetable oil blends" found in grocery stores are formulated to hit smoke points around 500°F. Choosing the right cooking oil is fundamental to both flavor and food safety, yet few home cooks understand the science behind smoke points.

Furthermore, avocado oil is rich in monounsaturated fats, which are more stable at heat than the polyunsaturated fats found in oils like corn or soybean. Refinement plays a critical role in this stability; the process of bleaching, filtering, and deodorizing removes impurities like free fatty acids, phospholipids, and particulate matter that would otherwise burn at lower temperatures.
An oil like grapeseed or unrefined sunflower oil might seem suitable due to its neutral taste, but its smoke point can be nearly 100 degrees lower than its refined sibling, leading to rapid breakdown and off-flavors. These oils undergo extensive processing that strips away impurities, allowing them to reach temperatures that would instantly burn less processed oils.
