What is refined cooking oil?
If the oil you buy is light and pale, you can be certain that it has been fully refined, bleached, and deodorized. Refined oils are extracted from clean oilseed/oil cakes by solvent extraction for further refining to produce clear oil, free from rancidity, and foreign matter. These oils are used as medium cooking oils (225°F – 350°F), high cooking oils (350°F – 450°F), and deep-frying oils (greater than 450°F). In essence, refined oils have minimal flavor and aroma ,which can be useful in delicately flavored dishes. Use for baking and sautéing, stir-fry and wok-fry, and oven cooking; to sear, brown, deep fry, and for tempura.
