The smoke point is a very important characteristic of oils as it shows how we can use the oil. Oils with a low smoke point are suitable only for salad dressing, while oils with a high smoke point can be applied for medium and high-heat cooking. When the oil is heated to its smoke point it breaks down and forms harmful free radicals. Corn oil has the smoke point of 450ºF. It is high enough for all types of cooking. The smoke point of vegetable oil depends on the constituents and may vary. On the whole, the smoke point of vegetable oil is not less than 400ºF as canola oil has such a smoke point and soybean oil and safflower oil smokes only at 450ºF (see Wikipedia for comparison of smoke points).
Usually vegetable oil is neutral in taste. Manufacturers blend oils in such a way to receive the oil without any taste. Corn oil also has a neutral flavor, but it adds some taste of roasted corn to the dishes cooked at a room temperature. Corn oil can sweeten food a little bit when it is heated.
