There are many benefits for soyabean oil. One of them is High smoke point.
The smoke point of an oil is the temperature at which fats start to break down and oxidize. This results in the formation of harmful, disease-causing compounds called free radicals, which can cause oxidative stress in the body. Soybean oil has a relatively high smoke point of about 450°F (230°C). For reference, unrefined extra-virgin olive oil has a smoke point of about 375°F (191°C), while canola oil has a smoke point of 428–450°F (220–230°C) . This makes soybean oil a good option for high-heat cooking methods like roasting, baking, frying, and sautéing, as it can withstand high temperatures without breaking down.
